Airspace Over Flooded Nebraska Nuclear Power Plant Still Closed
Ricky Kreitner | Jun. 15, 2011,
...

Fort Calhoun Nuclear Power Plant is an island, but authorities are hoping it stays dry.
...
A fire in Nebraska's Fort Calhoun nuclear power plant briefly knocked out the cooling process for spent nuclear fuel rods, ProPublica reports.  The fire occurred on June 7th, and knocked out cooling for approximately 90 minutes. After 88 hours, the cooling pool would boil dry and highly radioactive materials would be exposed. On June 6th, the Federal Administration Aviation (FAA) issued a directive banning aircraft from entering the airspace within a two-mile radius of the plant.
...
OPPD spokesman Jeff Hanson told Business Insider that the nuclear plant is in a "stable situation." He said the Missouri River is currently at 1005.6" above sea level, and that no radioactive fuel had yet been released or was expected to be released in the future.

Asked about the FAA flight ban, Hanson it was due to high power lines and "security reasons that we can't reveal." He said the flight ban remains in effect.

...
Fort Calhoun's single reactor has been shut down since April for refueling. The plant had already been operating under a heightened level of alert because of nearby flooding on the Missouri River, the NRC said. The cause of the fire remained under investigation this morning.

Is the U.S. Nuclear Plant near Omaha Nebraska at Risk of meltdown?

http://www.youtube.com/watch?v=b_IezA-ZkGw

Uploaded by offgridsurvivalist on Jun 15, 2011

With major flooding along the Missouri River the Ft. Calhoun Nuclear Plant near Omaha Nebraska was put at high alert. It's being reported that water had to be pumped into the containment area to cool the spent nuclear rods. The Local News crew was told not to report on the story or shot video of the plant.

Bad Combination: Floodplains, nuclear materials and understated risk
http://www.stlbeacon.org/voices/in-the-news/111003-flooding-raises-nuclear-risks
By Bob Criss, special to the Beacon  
Posted 7:00 am Fri., 6.17.11

It's only June but one thing is certain: 2011 is another extraordinary flood year. The record high water levels just experienced on the Mississippi from Cairo to Baton Rouge will soon be joined by new record levels on the Missouri River at numerous sites above Kansas City. The vagaries of rainfall delivery will dictate how bad things will become and how far downstream serious problems will propagate, but indications are that many dozens of levees will fail, either by overtopping, under-seepage or simply because they will be water saturated for long periods of time.

How is it that this extraordinary flood year came so soon after the extraordinary flood year of 2008, which came so soon after the extraordinary flood years of 2001, 1995 and 1993? The explanation is that damaging episodes of high water are no longer statistically extraordinary, but rather represent the new norm. Describing these events as "50-year," "100-year" or "500-year" floods grossly mischaracterizes what's happening.

Understated flood risk is not an academic matter. Faulty risk calculations are used by FEMA to set flood insurance rates that are too low and to define flood zones that are too narrow.

Understated risk promotes development projects that place property and lives in hazardous areas. Ironically these same developments encroach on rivers and floodplains in a way that amplifies flood frequency and increases floodwater levels. At the same time, valuable farmland is destroyed, habitat is eliminated and surface water and ground water resources are degraded.

In cases where floodplain development projects are encouraged by TIFFs and other inappropriate financial inducements, tax revenues can actually go down, even as municipal responsibilities to provide services such as police and fire protection go up.

Counterproductive enough? Not for some Now combine the high and progressively increasing likelihood of flooding with the placement of nuclear materials in floodplains. Let's examine two examples.

Incredibly, large volumes of the oldest radioactive waste materials of the Atomic Age were dumped at West Lake landfill in Bridgeton in 1973. From every conceivable viewpoint, the situation is deplorable. Radwaste does not belong in the most populous county in Missouri, near the Missouri River, upstream of several water intakes and within 1.5 miles of Interstates 70 and 270.

This site has high risk factors for flooding and is underlain by soils that have high potential to undergo liquefaction during seismic shaking. USGS maps indicate that the potential for strong shaking is significant in this area, so the possibility for slumping of the landfill or the protective levee is significant, particularly during flood years when shallow sediments become saturated. Moreover, the landfill does not have a clay liner or any other protective barrier, nor does it have the leachate collection and drainage systems that are standard in modern landfills.

The landfill is not capped, so wind erosion and rainwater penetration can disseminate radwaste. Historical slumping of the landfill has already spread radwaste over adjacent fields. The waste has not been adequately characterized, but enough is known to establish that its level of radioactivity will increase approximately tenfold over time. This can occur because the systematic decay of the radionuclides produces several additional short-lived "daughter" radioisotopes that will cause the radioactivity of this waste to grow for thousands of years. Few things are as absurd as burying such waste in a substandard landfill in a floodplain in a populous area.

As another example, two nuclear power plants in Nebraska have been constructed in the Missouri River floodplain where new records for flood levels are expected to be set this June. The Fort Calhoun Nuclear Plant has been recently sandbagged, only a year after the plant was cited for having inadequate flood protection. Floodwaters are already adjacent to several of the buildings, and water levels are projected to increase by at least five feet. Fortunately, the reactor was recently shut down for refueling, but about 300 tons of spent fuel rods have accumulated onsite over the years. Make no mistake; some of the most serious, recent problems and explosions at the Fukushima Daiichi nuclear plant involved spent fuel, not just the active reactors.

Of course, the NRC and power industry promoters routinely assure us that the risk of nuclear accidents is incredibly low, something akin to the probability of being attacked by a shark while riding a ski lift. The historical record provides a more realistic and vastly higher assessment of nuclear risk. More than 2 percent of the world's 440 nuclear power reactors have been irreparably harmed by nuclear accidents during their operating lifetimes - prominent cases are Chernobyl, Three Mile Island and Fukushima.

The bottom line is that understated risk is rampant and the consequences can be economically and environmentally disastrous. Understated risk fosters inappropriate land use in high-risk geologic areas, causing harm that can spread far beyond the boundaries of the offending properties. In contrast, realistic risk calculations and improved economic assessment of construction projects will promote wise land use and resource conservation, while reducing the economic burden caused by flooding or other disasters. Thoughtful stewardship will increase opportunities for research, innovation, enterprise and job creation, and ensure a brighter and more equitable future for all.

Officials: Nebraska nuke plant is well-protected, even though it’s surrounded by floodwaters
Friday, June 17, 10:50 AM

The plant 20 miles from Omaha is encircled by a giant rubber barrier. And it has been shut down since April. The Omaha Public Power District says the complex will not be reactivated until the flooding subsides.
...
the entire Omaha facility still has full electrical power for safety systems, including those used to cool radioactive waste. It also has at least nine backup power sources.

South Dakota eyes stepped up Missouri River dam releases

Michael Avok Reuters

2:26 p.m. EDT, June 18, 2011

HAMBURG, Iowa (Reuters) - Federal officials increased water releases from two South Dakota dams on Saturday to make room for expected potentially heavy rains through early next week, adding to flooding woes along the Missouri River.

The U.S. Army Corps of Engineers water releases from five dams in North Dakota and South Dakota had already about doubled prior records to relieve reservoirs swollen by heavy winter snows and spring rainfall at the river's Montana headwaters.

With severe storms expected through Tuesday that could dump inches of rain in some areas, the Corps plans to increase flows by nearly 7 percent at the Oahe Dam above Pierre, South Dakota's capital, and the Big Bend Dam just downstream.

"We do have the potential for a strong storm system," Andy Church, a National Weather Service meteorologist in Aberdeen, South Dakota, said on Saturday.

Some 2 to 3 inches of rain could hit areas of North Central and Eastern South Dakota, with flooding possible on the outside of levees in Pierre, Church added...

...The Corps plans to release 155,000 cubic feet per second from the Oahe and Big Bend dams on Saturday and 160,000 on Sunday, up from the roughly 150,000 it has been releasing.

  St' Louis is one of the flattest cities in America--flood prone to the max.

Not true, period.  Low laying areas are susceptible, like anywhere else, but the 93' and 95' floods drove most people out of those areas.

Floodwaters might hit KC by midweek
By MATT PEARCE
The Kansas City Star
FILE - In this June 14, 2011 file photo, the Fort Calhoun nuclear power station, in Fort Calhoun, Neb., is surrounded by flood waters from the Missouri River. The pictures of a Nebraska nuclear power plant were startling: Floodwaters from the swollen Missouri River had risen nearly to the reactor building, with the potential to climb even higher. Coming only a few months after Japan's nuclear disaster, the Associated Press images alarmed many people who saw them earlier this week. But nuclear regulators and the utility that runs the Fort Calhoun reactor say there is little cause for immediate concern.

Coming only a few months after Japan's nuclear disaster, the Associated Press images alarmed many people who saw them earlier this week. But nuclear regulators and the utility that runs the Fort Calhoun reactor say there is little cause for immediate concern.
 

Forecasts now say a peak wave of floodwaters from the Missouri River won’t hit the Kansas City area until roughly Wednesday.

But another forecast has drawn concern from the Army Corps of Engineers.

Heavy rainfall expected over the Dakotas in coming days, combined with rains from the past few weeks, have officials worried they’re running out of space in upstream dams, potentially forcing them to release even more pent-up water downstream.

“We’re watching the forecast every day,” said Jody Farhat, chief of the Army Corps’ Missouri River Basin water management division. “We’re a few days out before we have to make decisions.”

Army Corps officials are using a complex system of dams and levees to stop some water here, release a little there, tensely twiddling the knobs of the Missouri River in an effort to prevent as much flooding as possible.

The river, and the huge basin that feeds it, is a complicated machine where everything is variable: water levels that swell from bursts of rainfall, levees that break unexpectedly and an interconnected series of dams that shoot billions of gallons of water downstream.

One of the Army Corps’ biggest tools is the Gavins Point Dam, the last stop for the Missouri River in South Dakota, which will blast out a record 150,000 cubic feet of water per second through at least mid-August.

Officials now think they might have to boost the amount to 160,000 cubic feet, saying they’re running out of options to manage all the water upstream.

“At this point, we have very little flexibility remaining,” Farhat said.

The endless complexities have made prediction a tough task, said Ross Wolford, a hydrologist working long days for the National Weather Service in order to try to predict the river’s flow.

Dear Nebraska: Sorry about water, but more on the way. Love, Montana

 

From his tackle shop near Three Forks, Mont., Rich Gay is watching three rivers.
They're running high out of the mountains, skirting his town, fraying his nerves and converging, more than a mile away.
This is the headwaters of the Missouri River -- and the source this summer of so much Nebraska pain.
But this isn't where the flood begins.
The flood begins higher up, at places like Dark Horse Lake in the Bitterroots, where another 2 inches of snow fell late this week, landing on the 8 feet still on the ground.
And when hot weather finally reaches those upper elevations -- starting next month -- all of that snow will melt and flow and become, eventually, the floodwaters threatening Sioux City and Omaha and Plattsmouth and so many other river towns downstream.
"
It's all starting here," said Jim Brusda with the National Weather Service in Great Falls, Mont. "It's going to flow back down there toward Nebraska."
It will take its time to get this far downriver. The Dark Horse snowmelt, for example, first must find its way to the Clark Canyon Reservoir, then to the Beaverhead River, then to the Jefferson River.
The bloated Jefferson will join the Madison and Gallatin rivers near Three Forks -- and near Gay's tackle shop.
Where it was raining Friday afternoon. "And it's snowing in the mountains."
Seems like it's feast or famine with the Missouri, he said. Until this year, it's mostly been famine -- with downstream states demanding more Missouri River water from upstream states to keep barges moving.
Those downstream states have more than enough water now. But so does Montana.
"People who have been here 50 years, 70 years, say they haven't seen anything like this," Gay said. "All small streams, creeks are full. There are towns that are flooded and cut off. And there's a lot of water to come."
The snow-water equivalent in some areas is 400 percent; meaning, snow that usually is 2 feet deep this time of year is 8 feet, something that happens maybe once every 50 years, Brusda said.
I'M A DEPLORABLE KNUCKLEHEAD THAT SUPPORTS PRESIDENT TRUMP.  MAY GOD BLESS HIM AND KEEP HIM SAFE.

Declaration at Cooper Nuclear Station
As the Missouri River rises, the Nebraska Public Power District has declared a “Notification of Unusual Event” for the Cooper Nuclear Station. The notification was made at 4:02am Sunday. It is part of the safety and emergency preparedness plan that the station follows when certain flooding conditions are present.



Posted: 5:23 AM Jun 19, 2011
Reporter: WOWT-TV

NPPD says there is no threat to plant employees or the general public. The plant continues to operate safely. The Omaha Public Power District made the same declaration nearly two weeks ago when the Missouri River continued to rise near the Fort Calhoun Nuclear Station.

NPPD says its plans dictate that when the Missouri River’s water level reaches 42.5 feet, or greater than 899 feet above sea level, the notification of an unusual event is declared. If the river’s level increases to 900 feet above sea level, plant personnel will barricade internal doorways as another layer of protection for facility equipment. At 902 feet, the plant would be taken offline as a protective safety measure.

A Notification of Unusual Event is the lowest and least serious of four emergency classifications established by the Nuclear Regulatory Commission for nuclear power plants.

The Cooper Nuclear Station is three miles southeast of Brownville, Nebraska along the Missouri River.

Fort Calhoun Nuclear Plant: Radioactive Plume Projections Released For the CONUS

The Intel Hub

Looks as is there is more to this whole situation with the Garrison Dam (now at over 103% capacity according to documents obtained by our sources) and the mandatory evacuation of Minot North Dakota put in place by FEMA.

Troop, equipment, and other strange movements have taken place throughout the CONUS over the past week as The Intel Hub and The Power Hour has documented with photos, videos, and TIPs from good citizens.

This is all taking place during massive full scale military exercises — not good.

Over 56 NOTAM’s with a lot of suspicious VIP movements have be put in effect over the last two weeks (this is not normal).

The following is a simulation for a radioactive plume being released from the Nebraska Fort Calhoun Nuclear Plant:

Missouri River crests, breaking records of 1993 floods
By MATT PEARCE
The Kansas City Star

The Missouri River hit historic highs around northwest Missouri on Wednesday as officials prepared to unleash even more water into the area.

National Weather Service measurements taken near Big Lake and Phelps City, both about two hours northwest of Kansas City, showed crests beating every mark on record — even 1993’s peaks.

“Missouri River water will remain dangerously high for the foreseeable future,” said Col. Anthony Hoffman of the U.S. Army Corps of Engineers’ Kansas City office.

Residents in Holt County in northwest Missouri are already facing advancing floodwaters, which have defeated at least one levee there and are nearing the tops of others.

Meanwhile, Army Corps officials slowly opened up the Gavins Point Dam in South Dakota to release even more water downstream into the Missouri River to relieve overwhelmed reservoirs in northern states.

Gavins Point is expected to release 160,000 cubic feet of water per second starting today.

Levee breaks north of Brownville


Floodwaters from the Missouri river overtop a levy in Brownville, Neb., Sunday, June, 19, 2011. When the Missouri River reached 42.5 feet, or 899 feet above sea level Sunday morning, the Nebraska Public Power District issued a flooding alert for its nuclear power plant, Cooper Nuclear Station. Cooper, located near Brownville, is at 903 feet elevation, and NPPD officials said the river would have to climb to 902 feet at Brownville before officials would shut down the plant. (AP)

A levee three miles north of Brownville in Missouri failed at about 9 p.m. Thursday, right in front a pair of people patrolling there.

"It happened so quick that they were concerned that they may not be able to escape," Mark Manchester, deputy emergency management director for Atchison County, Mo., said late Thursday. "The water was coming through fast and hard. … We're not sure what the size of the break is so far."

Officials have ordered the evacuation of all of the county west of Interstate 29, he said. That includes the towns of Phelps City, Langdon and Watson, as well as the Nishnabotna Conservation Area.

Manchester said the extent of the breach likely wouldn't be clear until daybreak.

Flood berm collapsed at Nebraska nuclear plant

Posted: Jun 26, 2011 11:59 AM Updated: Jun 26, 2011 11:59 AM

FORT CALHOUN, Neb. (AP) - A berm holding back floodwater at the Fort Calhoun Nuclear Station has collapsed.

The U.S. Nuclear Regulatory Commission says it's monitoring the Missouri River flooding at the plant, which has been shut down since early April for refueling.

The 2,000-foot berm collapsed about 1:30 a.m. Sunday, allowing the swollen river to surround two buildings at the plant. The NRC says those buildings are designed to handle flooding up to 1014 feet above sea level. The river is at 1006.3 feet and isn't forecast to exceed 1008 feet.

The NRC says its inspectors were at the plant when the berm failed and have confirmed that the flooding has had no impact on the reactor shutdown cooling or the spent fuel pool cooling.

Flood wall fails at Fort Calhoun



By Sam Womack
WORLD-HERALD STAFF WRITER

Floodwaters surrounded several buildings at the Fort Calhoun Nuclear Station early Sunday morning after a water-filled wall collapsed.

The plant, about 19 miles north of Omaha, remains safe, Omaha Public Power District officials said Sunday afternoon.

The U.S. Nuclear Regulatory Commission is monitoring the Missouri River at the plant, which has been shut down since early April for refueling.

The 2,000-foot berm collapsed about 1:25 a.m. Sunday due to “onsite activities,” OPPD officials said. The Aqua Dam provided supplemental flood protection and was not required under NRC regulations.

According to the NRC, the berm was eight-feet tall and 16-feet wide at the base. It was designed to provide protection for the plant's "powerblock" for up to six feet of water.

Floodwater surrounded the nuclear plant's main electrical transformers, and power was transferred to emergency diesel generators.

OPPD spokesman Jeff Hanson said the transfer was precautionary because of water leaking around the concrete berm surrounding the main transformers.

He said efforts are underway to reconnect to offsite power once all safety checks have been completed.

The floodwaters also surrounded auxiliary and containment buildings, which are designed to handle water up to 1,014 feet above sea level. The Missouri River is at 1,006.3 feet and isn't expected to exceed 1008 feet

I dont want to be a fear-monger, but when Fukushima was still being sold as a minor incident they set up a 500 mile zone around the plants, so for our purposes here, assuming a low-level radioactive incident is taking place around Omaha ( which has been given evacuation information for the flooding by Fox news ), I have extrapolated a NON-SCIENTIFIC map of a 500 mile green zone and a 200 mile red zone. Im no certified expert, so dont go sharing this map as if its something certain, but i personally would recommend to friends or family living in the red zone to leave immediately. The reason for this, is that I would not stay there.

Flood wall fails at Fort Calhoun

By Sam Womack
WORLD-HERALD STAFF WRITER

The Fort Calhoun Nuclear Station turned to diesel-powered generators Sunday after disconnecting from the main grid because of rising floodwaters.

That move came after water surrounded several buildings when a water-filled floodwall collapsed.

The plant, about 19 miles north of Omaha, remains safe, Omaha Public Power District officials said Sunday afternoon.

Sunday's event offers even more evidence that the relentlessly rising Missouri River is testing the flood worthiness of an American nuclear power plant like never before. The now-idle plant has become an island. And unlike other plants in the past, Fort Calhoun faces months of flooding.

Floodwater surrounded the nuclear plant's main electrical transformers after the Aqua Dam, a water-filled tubular levee, collapsed, and power was transferred to emergency diesel generators.

OPPD officials said the transfer was precautionary because of water leaking around the concrete berm surrounding the main transformers.

Plant operators later reconnected to off-site power once all safety checks had been completed.

Water now surrounds the auxiliary and containment buildings, which are designed to handle flooding up to 1,014 feet above sea level. The river is at 1,006.3 feet and isn't forecast to exceed 1,008 feet.

The U.S. Nuclear Regulatory Commission is monitoring the Missouri River at the plant, which has been shut down since early April for refueling. The Fort Calhoun plant will remain surrounded at least through August as the U.S. Army Corps of Engineers continues dumping unprecedented amounts of water from upstream dams.

The 2,000-foot berm collapsed about 1:25 a.m. Sunday due to “onsite activities,” OPPD officials said. The Aqua Dam provided supplemental flood protection and was not required under NRC regulations.

“We put up the aqua-berm as additional protection,” said OPPD spokesman Mike Jones. “(The plant) is in the same situation it would have been in if the berm had not been added. We're still within NRC regulations.”

The NRC says its inspectors were at the plant when the berm failed and have confirmed that the flooding has had no impact on the reactor shutdown cooling or the spent fuel pool cooling.

PCTRAN
http://www.ues-egypt.com/Nuclear_Power.htm

PCTRAN is nuclear power plant simulation software specifically designed for beyond - design-basis accidents including severe accidents and intentional sabotage . Core melt, containment and spent fuel pool failures are within its scope.

The sixth generation of PCTRAN extends NPP simulation to offsite dose projection. All operational and radiological release data are accessible by onsite and remote technical support or corporate personnel. During a training or exercise session, a client may even conduct its own projections and feedback to the server end instructor or emergency control director.

Given increased concern in intentional or complicated events, PCTRAN prepares a nuclear power plant's personnel with realistic training and exercise. The web-based simulator extends to severe accidents, generates radiological release source terms and makes area dose projection according to live meteorological conditions . Its speed can be either real-time or many times faster. Operation is user-friendly in its graphical-user-interface (GUI). All graphics, text messages and data are transmitted seamlessly back and forth via existing IE Explorer.

In the plant mimic, there are icons showing simultaneous containment failure, reactor coolant boundary leak and fuel pool damage. The combined radiological releases contribute to dose distribution in EPZ. This can aid EAL determination as well as protective shielding or evacuation recommendation.

Transient Simulations

Selection of a transient is menu-driven that includes all possible disturbances to a plant such as:

•  Normal operation control - startup, shutdown, power ramp
•  Loss-of-coolant-accident (LOCA) or steamline break
•  Loss of flow, single or two-phase natural circulation
•  Turbine trip with or with bypass, station blackout
•  Steam generator tube rupture (PWR)
•  Feedwater transients
•  Anticipated transient without scram (ATWS)
•  Damage to containment or spent fuel storage facility (for example, caused by airplane crash)
•  Intentional sabotage by terrorist group to cause a reactivity event, fire or loss of diesel

•  Any combination of above

Severe Accident Model

The core is modeled into six vertical nodes. Each one will generate a portion of the decay heat. When the boundary heat removal rate is less than the core heat, the core node is heated up to the point of melting. Molten fuel may collapse into the bottom of the vessel. The vessel lower head may then heat up to the melting point, too. The molten debris may drop into the containment cavity floor. During the fuel damage process, first the fission gas in the clad may leak out. Later if the fuel and cladding continue their degradation, fuel isotopes will release also. In addition to iodine and noble gases, there are alkali metals, tellurium, barium, cerium, lanthanides, etc. The elevated concentration of these radioactive isotopes would find their ways through the vessel break, relief valves, and containment leakage into the environment.

PCTRAN is most powerful in its versatile and interactive control. The user can at any time manually trip the reactor or the pumps, open or close a relief valve, override the ECCS or change the set points for a number of the control systems. All transient parameters are available for trending during execution or printed after the run. The data can be saved in Access or Excel files for later usage. The restart capability can virtually extend a transient simulation to indefinite time period.

RMS Source Term & Area Dose Projection

Available as an option, the extended simulation model keeps track of fission product transport along the major release pathways. Normal and accident condition readings of major area, effluent, and process radiation monitors throughout the plant are displayed in a separate mimic. Iodine, noble gases and other fission products based on Regulatory Guide 1.183 Revised Source Terms are calculated periodically. Plume or puff release is then projected for variable wind speed and stability factors in the Emergency Planning Zone.

Available Plant Models

MST has completed the following models in Windows:

•  GE BWR 2 (Oyster Creek), 4 (Peach Bottom), 5 ( La Salle ), 6 (River Bend) and ABWR (Lungmen) with Mark I, II, III or advanced containment
•  Westinghouse 2-loop ( Point Beach ), 3-loop (Turkey Point) and 4-loop ( Salem ) PWR dry containment or ice condenser containment (Sequoyah)
•  Westinghouse AP1000
•  C-E PWR's of 2x4 hot/cold loops (St Lucie and Fort Calhoun ), System 80+, Korean Advanced PWR
•  B&W (now Areva) PWR's of once through steam generators (TMI)
•  Framatome PWR's ( Guangdong ) or Areva EPR 1600
•  ABB BWR's (TVO)
•  Russian VVER-440 and 1000 of horizontal steam generators
•  Westinghouse AP1000 Passive Containment Cooling System

Computer Configuration   

Any Pentium or compatible PC with SVGA graphic monitor and color printer is required. The operating system should be Windows 2000, XP or NT with MS Office Suite installed. Simulation speed is adjustable from real-time to fast time. For a 1.4 GHz processor, the maximum speed is about 16 times faster than real-time.

Free CDROM   

A full capability demonstration package is available upon request. Alternatively, a number of plant types' can be downloaded from MST's website http://www.microsimtech.com

APPLICATIONS

ABSTRACT

The PC-based reactor simulation software PCTRAN was recently expanded to cover light water advanced reactors. The plant models include Generation III+ advanced PWR and BWR. The evolutionary designs are Areva EPR and GE ABWR by adding cooling path redundancy and devises for severe accident mitigation. One-step further is the passive-cooled Westinghouse AP1000 and GE ESBWR. Combined with PCTRAN’s models of experimental pool reactor and conventional PWR and BWR with server accident and dose dispersion capability, it forms a complete series for education in nuclear technology. The PC-based simulation system helps to train the first generation of technical staff for countries entering the nuclear era.

1. INTRODUCTION

PCTRAN is a PC-based simulation code using reduced thermal hydraulic nodes for transient prediction. Advancedtechnique significantly simplifies numerical solution process. Since its first introduction (Po 1988), it has evolved from DOS to Windows-XP environment. Operation is in standard Windows graphical-user-interface (GUI) for friendly interactive control.  For training and education of the first generation of technical staff in countries emerging into nuclear power, PCTRAN is a “live” simulation tool complementing classroom lectures. Concepts of neutron multiplication, criticality, feedback, decay heat and Xenon poisoning can be demonstrated in PCTRAN’s experimental pool reactor model. For that many of the countries have already operated for years with ample experience. Next there are conventional PWR and BWR models. In addition to normal operation of start-up, power manoeuvre and shutdown, operational transients and accidents can be simulated at a speed faster than real-time. The severe accident model allows core-melt and containment failure in the event of multiple failures of the emergency core cooling system or human error.

Anticipating second coming of nuclear era, new constructions are likely advanced models with additional core-cooling redundancy and passive devises. There are European, Russian, Japanese and Korean designs of evolutionary PWRs with improved ECCS and containment designs. The calculated core degradation frequency (CDF) is reduced by one order of magnitude (to 10-6 /year) than the conventional PWR’s. Westinghouse AP1000 (Westinghouse 2004) uses passive heat sink and natural forces to remove decay heat. On the BWR side there is General Electric/Hitachi Advanced BWR (ABWR) with reduced piping and enhanced severe accident mitigation capability. Using the same passive concept, the Economical and Simplified BWR (ESBWR) also eliminates active ECCS. Its CDF is reported down to 10-8 /year (GE/Hitachi 2005).

In this paper the experimental pool, AP1000 and ABWR are selected for presentation. In order to cover nuclear safety all the way to general public, radiological release from severe accident and offsite dose dispersion forms the integrated PCTRAN simulation system.

Since 1996 the International Atomic Energy Agency (IAEA) has selected PCTRAN as the training material in its annual Advanced Reactor Simulation Workshop (Cleveland 2006). Over the years a number of institutions all over the world have licensed various models into their curricula. As the Gulf States are in the dawn of nuclear power development, it could contribute further in the region’s education and development.

2. WINDOWS BASED SIMULATION SYSTEM

Taking advantage of 32-bit PC technology, PCTRAN is written in Microsoft Visual Basic 6. Operation follows strictly the Windows XP environment in graphic-user-interface (GUI). Data input/output are in Access database format. Selection of equipment malfunctions and accident types are from a drop-down menu. It includes all possible disturbances to a plant:

• Normal operation control – start-up, shutdown, power ramp
• Loss-of-coolant-accident (LOCA) or steam line break
• Loss of flow, single or two-phase natural circulation
• Turbine trip with or with bypass, station blackout
• Steam generator tube rupture (PWR)
• Feedwater transients (pipe break, loss of feed or loss of heating)
• Anticipated transient without scram (ATWS)

• Containment failure (failed isolation or containment breach)
• Loss of AC power (loss of offsite grid and loss of diesel emergency power)
• Any combination of above

Execution is default to real-time speed. It could be accelerated to 2, 4, and 8 or up to16 times faster for long transients. All automatic and manual actions are recorded in a log text file. Transient curves can be transferred conveniently through Office Suite over a network. Online “Help” is provided that assists comprehensive user’s manual for easy instruction.

3. EXPERIMENTAL POOL REACTOR

The reactor is rated at 200 KW thermal with neutron flux at 2x1010 n/cm2/sec. It is intended for education of reactor principles, isotope production and research in irradiation. Concepts of delayed-neutron effect, multiplication factor, control by rods and boron concentration, feedback on fuel (Doppler) and moderator temperatures, criticality, xenon and samarium poisoning, etc. can be demonstrated. Delicate manoeuvre of the rods during start-up to criticality is possible. It is a powerful tool complementing classroom lectures. The database is structured to allow varying the reactor size from a few kilowatts up to megawatt range for any specific pool reactor.

4. WESTINGHOUSE AP1000

Westinghouse AP1000’s nuclear and secondary steam supply system (NSSS) is similar to a conventional PWR. The core is rated at 3400 MWt or 1000 MW electric at full power. The reactor primary coolant has two steam generators with four coolant pumps (2x4 configuration). PCTRAN’s Figure 2 right hand side control panels are for normal operation. There are rod control system, pressurizer and steam generator pressure and level controls to keep the plant at desired operating condition. The Chemical and Volume Control System (CVCC) panel is located in the lower left. It is composed of charging pumps and letdown valves for reactor coolant purity and inventory control - the same as conventional PWR.

At left there are panels for the passive emergency core cooling systems. At top there is In-Containment Refuelling Water Storage Tank (IRWST). Two Passive Residual Heat Removal (PRHR) heat exchangers are submerged in the IRWST. Three stages of Automatic Depressurization System (ADS) on top of the pressurizer are provided to relieve steam into the IRWST. The fourth-stage ADS valves are connected to the hot legs and relieve steam directly into the containment atmosphere. They are opened in sequence during a small break loss-of-coolant accident to accelerate depressurization.

Instead of an active high-pressure injection system that requires safety-graded pumps and emergency AC power supply, a passive system of Core Makeup Tanks (CMT), accumulators (ACC) and drain valves from the IRWST are provided. Their respective panels are located in the middle-left section. Depending upon extent of pressure reduction following a LOCA, CMT, ACC and IRWST drains are initiated in sequence to provide coolant makeup into the core.

For containment cooling the reactor building is designed as a Passive Cooled Containment System (PCCS). Different from conventional PWR, the containment spray is applied on the outside shell of a steel lining. The PCCS water storage tank is located at the top of the concrete structure. For a design basis scenario, it is activated in the event of high-pressure reading within the containment. It would take place if the normal heat removal (the containment fan coolers) unavailable for an extended period of time. The heat transfer is enhanced by a water film formed by gravity drain of water onto the containment shell.  The tank has sufficient water to provide three days of cooling. The atmosphere is the ultimate heat sink for the reactor system. In PCTRAN AP1000 containment mimic (Figure 3), the valve colour changes and digitally displayed flow rate indicates activation of the passive systems. The containment concrete structure with the baffle provides for natural circulation of outside air. The air enters into the gap between the concrete containment and the baffle at the top, flows down the outside of the baffle, and rises up along the steel containment vessel. The heat is thus transferred through the containment vessel to the environment.

5. GENERAL ELECTRIC ABWR

The plant model is the General Electric (GE) designed Advanced Boiling Water Reactor (ABWR) plant of 1350 MWe. The reactor uses 10 reactor internal pumps that reduce probability of external pipe break. A containment overpressure protection system is designed to mitigate consequence of a severe accident. The Standard ABWR Final Safety Analysis Report (FSAR) and Taiwan Power Company’s Fourth Nuclear Power Plant Lungmen Project was used for PCTRAN-ABWR model input.  The upper and lower drywell is modeled in the containment model. The suppression pool (wetwell) surrounds the drywell. Horizontal vents connect the two compartments. There are vacuum breakers to balance the pressures of the two compartments after a major blowdown. The nuclear steam supply system is designed in a mimic as shown in Figure 4.  PCTRAN/ABWR was used for verification and validation of Lungmen Project’s instrumentation and control system software at the Institute of Nuclear Energy Research of Taiwan (Huang 2007).

6. SEVERE ACCIDENT MODEL

A severe accident is defined as beyond design-basis with significant core damage and containment failure. A borderline is usually set in probability safety assessment (PSA) Division 2 for top of the fuel (TAF) uncovery, and Division 3 for fission product relocation. During the clad heat-up Zirconium may interact with steam to generate hydrogen and release more heat into the system.

The core is modelled into six vertical nodes. Each one will generate a portion of the decay heat. When the boundary heat removal rate is less than the core heat, the core node is heated up to the point of melting. Molten fuel may collapse into the bottom of the vessel. The vessel lower head may then heat up to the melting point, too. The molten debris may break the vessel bottom and drop into the containment cavity floor. During the fuel damage process, first the fission gas in the clad may leak out.  Later if the fuel and cladding continue their degradation, fuel isotopes will release also. In addition to iodine and noble gases, there are alkali metals, tellurium, barium, cerium, lanthanides, etc. The elevated concentration of these radioactive isotopes would find their ways through the vessel break, relief valves, and containment leakage into the environment. The molten core and metal mixture is called corium as it interacts with concrete and forms a slump. At lower temperatures, degassing of concrete occurs and steam, hydrogen and carbon dioxide can be released. At higher temperatures concrete can also be melt and mixed with metals. Since Ca, Fe, Si, Al, Na, Mg, Mn, Cr, etc. normally form concrete, the most important corium-concrete interactions (CCI) are:

Fe + CO2 -> FeO + CO + Q1
Fe + H2O-> FeO + H2 + Q2
Ni + H2O -> NiO + H2 + Q3
Zr + 2H2O -> ZrO2 + 2H2 + Q4
2 Cr + 3 H2O -> Cr 2O3 + 3 H2 + Q5

Where Q’s are reaction heat that could be either positive or negative. Each reaction rate is temperature-dependent and given by the parabolic law:

K = R5 exp (-G/T) (kg/M2)/sec, T in Kelvin

In PCTRAN they are weighted and lumped together into a single form representing progression of CCI. In the core Zr-water reaction calculation, cylindrical geometry has been used for vertical tube bundle configuration. For CCI it is instead a semi-hemisphere configuration to represent the slump pile of debris.  The top hemisphere interacts with atmosphere above, and the bottom flat surface interacts with concrete floor. A red slab represents the molten pool of concrete in Figure 6 mimic display.

7. OFFSITE DOSE DISPERSION

Having generated the release source term from a power plant, the Gaussian puff model and numerical techniques (Cheng, 2008) are utilized to calculate the radioactive effluent dispersion. During the transient simulation, puffs are sequentially generated and dispersed in all directions governed by the Pasquill stability category, wind velocity and wind direction. The thyroid dose rate and whole body dose rate (as well as their accumulations) at every spatial location in the neighbourhood are shown as a color-shaded plot (Figure 7).

The releases of radioactive materials are treated as unsteady emissions in non-homogeneous dispersion conditions. The meteorological condition can vary between Pasquill stability category A (most unstable) to F (most stable), wind speed in meters per second and release elevation from ground up to a few hundred meters. The Gaussian puff model is used to predict the time-varying dose distributions. It is more realistic than the Gaussian plume model that assumes the emission is continuous and constant in steady-state meteorological conditions. The model describes the effluent dispersion in the horizontal and vertical directions. It is two-dimensional semi-infinite sphere with elevated release. The projected dose rate and integrated dose are used for emergency activation level determination and recommendation of shielding or evacuation during an exercise (Po 2008).

8. CONCLUSION

PCTRAN family of codes form a complete teaching platform for nuclear technology. The following aspects are integrated into one simulation system:
- On Basic Reactor Concept: From reactor physics, thermal-hydraulics to plant control
- On Actual Plant Designs: From experimental pool reactor to advanced PWR and BWR
- On Plant Operations: From normal start-up, shutdown, power operation to transient and accident mitigation
- On Defence-in-depth Concept: From fuel element, reactor coolant and containment boundary to severe accident and offsite dose dispersion

Other than the generic version acquired by IAEA and taught in its workshop for the pass twelve years, various models have been licensed to universities all over the world. These include universities of Cincinnati, Georgia Tech, Lowell, Michigan, MIT, NJIT, North Texas, Rensselaer Polytechnic and Naval Academy in the US; Fukui Tech, Kobe Shosen, Kyushu, Osaka, Tokyo, Tohoku and Tokyo IT in Japan; Tsinghua (Beijing), Tsinghua (Taiwan), SJTU, XJTU, Hong Kong U and HK City U in China; Polytechnic Madrid and Polytechnic Barcelona in Spain; Sharif of Iran; King Abdulaziz of Saudi Arabia; Chulalongkorn of Thailand and Sherbrooke and McMaster in Canada.

These institutions have used the executable programs and accompanied documentation as teaching aid in their reactor physics and nuclear power plant technology classes. Some of them have further acquired external sponsors’ financial support for licensing the source codes and assistance from Micro-Simulation Technology. Their faculty and graduate students have then developed advanced models and specific applications using PCTRAN’s Visual Basic platform. Over the years two PhD’s and dozens of Masters have completed their thesis. Examples are Taiwan Tsinghua’s contribution in the puff dispersion model (Cheng 2007) and a fault detection system for Lungmen Project’s (ABWR) I&C system (Huang 2007). University of Cincinnati has contributed in the severe accident model.

PCTRAN was first introduced to King Abdulaziz University via IAEA’s sponsorship in 1998. As the Gulf States are in the dawn of nuclear power construction, it could contribute further in the region’s nuclear education and development.

While examining the data sets from our most recent gathering in the effort to produce the upcoming (July 1 most probably) report, data relating to the [nuclear plants (central USofA)] emerged in 3/three different entities.

First we note this is a projection of language that *may* emerge in the mainstream media (aka propaganda press) over these next few weeks. Second we note that the data sets referenced are from the most recently gathered immediacy value sets.

The primary aspect/attribute that we have for the [flooded nuclear plants] headed by the descriptor of [fog]. This is a multiple layered context, and includes supporting sets for [fog (over knowledge)], and [fog (radioactive)], and [fog (of confusion from officialdom)], and further, [fog (of confusion (in populace) over what to do/where to go?)]. Deeper layers of detail show the [fog] becoming [so dense] as to [obscure] the [center (of the site).

More distressing is that the [fog] is described as [obscuring the details (of the restraints?)] and [limiting (the view of) the developing disaster]. Please note it is a bad sign when our data sets have such bespoke nasty words as [disaster]. Further disturbing words include [isolation], and [humilation (of attendees)], and [not good news (that must be absorbed)]. Other details include sets for [punishment] {ed note: associated with minion class, officialdom...again, not a good sign}, and [attempt (at restoring) order], and [failure (to take every precaution) at the beginning]. Again, NOT good signs for a good resolution.

Other NOT good signs include a heavy weighting of release language from the 21st through the 25th of June with a special emphasis on the Populace/USofA. Especially noteworthy is a set of data with very high emotional sums that is centered on [release (of explosive noises) over water] that will be in place in about 9/nine days.

Also please note that we are only nearing 46 per cent of the forecast [flood] language for the Populace/USofA for this Spring/Summer. Sooooo.....likely a few more [flood] related news stories will be showing up after we cross the solstice in a few days.

As this is immediacy data, and likely is manifesting as you read this, not too much more that can be said of a meaningful nature as time will very soon provide the unfolding of the next stage of the [flood] language for our edification and elucidation.

Omaha is clearly going to get the worst of it but there are a number of towns within this 200 mile area that should probably leave before floods or otherwise. That means Lincoln, Fremont, Arlington, Blair, Tekamah, Oakland, Logan, Missouri Valley, Woodbine, Blair, Onawa, Mapleton, Sloan, Sioux City, Norfolk, Stanton, Wisner, Madison, West Point, Wayne, Wakefield, Pender, David City, Stromsburg, Seward, York, Geneva, Friend, Crete, Wilber, Beatrice, Wymore, Pawnee City, Tecumseh, Auburn, Falls City, Mound City, Oregon, Sabetha, Rock Port, Tarkio, Maryville, Bedford, Clarinda, Villisca, Corning, Lenox, Mt Ayr, Creston, Griswold, Greenfield, Atlantic, Anita, Stuart, Guthrie Center, Panora, Audubon, Manning, Cooper, Jefferson, Glidden, Carrol, Dennison, Lake City, Lake View, Odebolt, Sac City, Holstein, Ida Grove, and the rest of them.

  Ekim, many of these places should be OK because they are at higher elevations UNLESS THERE IS A MELTDOWN.

something to keep an eye on, as well,  is the Gavin's Point Dam
Nothing I write has any relevance to anything and cannot be proven one way or another. If you're looking to point the finger, point it at AJ, it's his fault.
