NRC WILL HOLD A PUBLIC MEETING TO DISCUSS 2010 PERFORMANCE ASSESSMENT OF SOUTH TEXAS PROJECT NUCLEAR POWER PLANT

STP Houston and Corpus ChristiMost of us are familiar with the 10 and 50 mile zones around Fukushima, this map shows those same zones around the South Texas nuclear plant located just 76 miles outside of Houston.

The Nuclear Regulatory Commission staff will meet in Bay City, Texas, on Thursday, May 19, with representatives of South Texas Project (STP) Nuclear Operating Co., to discuss the agency’s assessment of safety performance for the South Texas Project nuclear power plant located near Bay City.

The meeting, which will be open to the public, is scheduled to begin at 5:30 p.m. at the Wharton County Junior College (Center for Energy Development) 4000 Avenue F, Bay City, Texas.

In addition to the performance assessment, the NRC staff will be available to answer questions from the public on the safety performance of the South Texas (Nuclear) Project and the NRC’s role in ensuring safe plant operation.

The meeting will provide an opportunity for NRC to discuss their annual assessment of the plant with the company, local officials and the public.   NRC will answer any questions attendees may have about their oversight.

A letter sent from the NRC Region IV office to plant officials addresses the performance of the plant during 2010 and will serve as the basis for discussion. It is available on the NRC website – click here to read the letter.

In light of public concerns that have emerged regarding the safety of nuclear plants here in the U.S. in the wake of the Japanese nuclear disaster at Fukushima, this public meeting provides an excellent opportunity for citizens living 10, 50, or even 150 miles away to find out what measures are in place at South Texas Project to protect it’s neighbors.

In a memo issued today, the U. S. Nuclear Regulatory Commission (NRC) said that the failure of a low pressure coolant injection valve last fall at the Browns Ferry nuclear plant, located near Athens in north Alabama, was of “high safety significance

NRC inspection findings are evaluated using a safety significance scale with four levels, ranging from “green” for minor significance, through “white” and “yellow” to “red” for high significance. On Oct. 23, 2010, a valve failed to open when operators attempted to use a shutdown cooling loop during refueling. Tennessee Valley Authority (TVA), the plant operator, later determined that the last time the valve had definitely worked as required was on March 12, 2009 when the loop was placed in service. At the time, the public was not endangered because no actual event occurred. However, the system is counted on for core cooling during certain accident scenarios and the valve failure left it inoperable, which potentially could have led to core damage had an accident involving a series of unlikely events occurred.

An accident such as the one that occurred on April 27th when the town of Tuscaloosa, Alabama, only 100 miles south of the Browns Ferry nuclear plant, was devastated by an estimated EF-4 tornado over a mile wide that stayed on the ground for 2 hours, leaving behind a shocking landscape of twisted wreckage for seven miles.  That same storm cell took out transmission lines to the plant causing it to lose offsite power and triggering the three units at the plant to shut down automatically.

A regulatory conference to discuss the issue was held on April 4, just weeks before the massive tornado cell swept through the southeast. TVA stated that the failed valve was the result of defective manufacturing but still would have opened and supplied the necessary cooling water. The NRC review disagreed and concluded the violation was “red” or of “high safety significance.” The valve was repaired after its failure was discovered last October and prior to returning the unit to service, however the NRC has determined that significant problems involving key safety systems warrant more extensive NRC inspection and oversight. 

Had the problem not been discovered and repaired six months before the the tornados shut down the plant, would the outcome have been different?  More Fukashima-like?  The increased scrutiny of the nation’s aging nuclear industry, due in large part to the disaster in Japan, is uncovering some disquieting issues.  Will the NRC’s return to being a regulatory agency instead of a shill for the industry, and their heightened oversight prevent another nuclear disaster – or is it only a matter of time before an undetected problem at a plant, coupled with unforeseen events, has the US coping with its own disaster?

NRC WILL HOLD A PUBLIC MEETING TO DISCUSS 2010 PERFORMANCE ASSESSMENT OF COMANCHE PEAK NUCLEAR POWER PLANT

Comanche Peak

Most of us are familiar with the 10 and 50 mile zones around Fukushima, this map shows those same zones around the Comanche Peak nuclear plant located just 38 miles outside of Fort Worth.

The Nuclear Regulatory Commission staff will meet in Glen Rose, Texas, on Thursday, May 12, with representatives of Luminant Generation Co., to discuss the agency’s assessment of safety performance for the Comanche Peak Nuclear Power Plant. The plant is located near Glen Rose.

The meeting, which will be open to the public, is scheduled to begin at 6 p.m. at the Somervell County Expo Exhibit Hall, 102 Northeast Vine Street, Glen Rose, Texas.

In addition to the performance assessment, the NRC staff will be available to answer questions from the public on the safety performance of Comanche Peak and the NRC’s role in ensuring safe plant operation.

The past several days have been yet another reminder that the hubris of modern engineering can be brought low by the extreme power of mother nature.

The Nuclear Regulatory Commission said it was monitoring the Browns Ferry nuclear power plant near Athens in north Alabama, after it lost offsite power Wednesday night due to the storms.  While there was no direct hit from a tornado at the plant, the storms did take down the transmission lines from the plant causing the three units at the plant to shut down automatically when power was lost.

According to the Tennessee Valley Authority, which operates the plant, one of the plant’s diesel generators was out of service for maintenance, but the other seven started to power the units’ emergency loads that provide cooling for the reactors.  No radiation was released as a result to the shutdown and the plant remains in a “safe” shutdown mode (you know, like Fukushima Dai-ichi’s units 4 thru 6).  Plant operators and Tennessee Valley Authority line crews are working to restore offsite power to all three units but the plant is expected to be down for days and possibly weeks while repairs to the transmission lines are made.

Meanwhile, less than two weeks ago, the Surry nuclear power plant lost offsite power early in the evening, of April 16th when a tornado touched down in an electrical switchyard next to the plant.

The two units at the Surry plant automatically shut down and four of the plant’s diesel generators started to power the units’ emergency loads. As of this writing, NRC’s website shows Surry 1 back online, but Surry 2 is still offline. 

Tuscaloosa, Alabama, only 100 miles south of the Browns Ferry nuclear plant, was devastated by an estimated EF-4 tornado over a mile wide that stayed on the ground for 2 hours, leaving behind a shocking landscape of twisted wreckage for seven miles.  In light of the devastation wrought by this storm, we should count ourselves very fortunate that these nuclear plants were only the victims of downed transmission lines and damaged adjacent switching yards.  While the reactor containment might be able to withstand a tornado of this magnitude, we don’t know how vulnerable the backup systems would be. 

One of the lessons we should take away from Fukushima should be – never underestimate the power of mother nature or overestimate our ability to engineer things to withstand the extremes that nature can throw at us.

The Nuclear Regulatory Commission (NRC) voted to launch a review of US nuclear power plant safety in response to the March 11th Japan earthquake and tsunami which resulted in the crisis at Japanese nuclear power plants.

The NRC plans to establish an agency task force, made up of current staff and former NRC experts that will conduct both short- and long-term analysis of the situation in Japan and implications for U.S. nuclear plants.  They also announced that the results of their work will be made public.

In addition to the NRC’s response to the events happening in Japan, investors are scaling back their investments in U.S. power companies that have the biggest exposure to nuclear plants because of regulatory uncertainty in reaction to the Japanese crisis.

Public and political scrutiny of the 104 U.S. nuclear reactors erupted as the world watched Japan racing to prevent a meltdown and contain radiation at Tokyo Electric Power’s (Tepco) Fukushima Dai-ichi reactors in the wake of the Japanese earthquake and tsunami. The ensuing sell-off in U.S. utilities with nuclear plants points to fears that these companies face greater regulatory hurdles and significant costs to keep their plants open.

Interestingly enough, NRG Energy (NRG) shares jumped 5.4%  on expectations that the power company will abandon its South Texas nuclear Project expansion, especially if its Japanese partners pull out, including Tepco who had announced they were going to partner with NRG and Toshiba for  a 10% share of the expansion, and possibly increase that to 20% if a U.S. loan guarantee was awarded to the project.

NRG has announced that they will back off of additional development of STP reactors 3 & 4, while awaiting federal guidance regarding safety issues resulting from the nuclear disaster in Japan. The reactor site in Bay City, Texas, is 100 miles from Houston.
Reactor safety has long been a concern of Public Citizen and the Sustainable Energy and Economic Development (SEED) Coalition. The disaster in Japan illustrates the danger of fires and explosions and of putting many nuclear reactors in the same location.  The SEED Coalition raised these concerns in legal opposition to the licensing of two additional South Texas Project reactors and anticipate an Atomic Safety and Licensing Board hearing this Fall. This case is likely to set important precedent as it will be the first in the nation to examine these safety issues in new reactor licenses.
The risks of nuclear power are real and apply to U.S. reactors as well as those in Japan. At the South Texas site, a hurricane could knock out power and flood diesel generators, leading to a loss of coolant and potentially a meltdown.  Human error or technological problems can lead to accident scenarios.  Drought conditions are expected to worsen so low river flows could threaten the ability to cool existing reactors. Hopefully, we’ll never see a terrorist attack, but that is a possibility too. We believe it is time to use safer, more affordable ways to generate electricity.
SEED Coalition recently raised safety issues in opposition to the re-licensing of reactors 1 and 2, which are set to retire in 2027 and 2028. The NRC is considering allowing them to operate another 20 years past their originally intended lifespan. Reactors become more risky as they age, and we do not believe another 20 years of operation is safe. We must prevent a serious accident from happening here.
There have been plenty of problems with the existing reactors, both of which were shut down for over a year in the 1993-94 timeframe due to problems with the auxiliary feedwater pumps and diesel generators. Houston Lighting and Power was fined $500,000 for safety violations.
Click here for a summary of historical problems at the site.
The public can comment on STP re-licensing until April 1st.  Click here for information on how to comment.

Even as the Japanese attempt increasingly frantic tactics to cool an overheated nuclear complex:  

  • U.S. officials warned the situation is deteriorating and challenged the Japanese government’s assessment of the radiation risks telling U.S. civilians and military personnel to stay at least 50 miles from the facility, in contrast to the 12-mile evacuation zone set by Japan.
  • The Nuclear Regulatory Commission Chairman Gregory Jaczko told lawmakers that the U.S. believed the damage at the Fukushima Daiichi nuclear power complex was even graver than Japanese officials had outlined in public; and
  • U.S. Energy Secretary Steven Chu told those same lawmakers that he believed a “partial meltdown” had occurred at the Japanese nuclear power plant and that the accident was “more serious” than the 1979 partial core meltdown at Three Mile Island in Pennsylvania.

In the meantime, Jonathan Silver, executive director of the Energy Department’s loan guarantee program affirmed that it will continue to finance nuclear projects in the United States during a presentation he made today at the Cleantech Forum conference in San Francisco.

Mr. Silver’s remarks followed Congressional testimony in Washington by Energy Secretary Steven Chu and Gregory B. Jaczko, chairman of the Nuclear Regulatory Commission. In the same testimony that cautioned the situation at the Fukushima Dai-ichi plant was more serious than Japanese officials were saying,  Dr. Chu said that the Obama administration continued to support nuclear energy, noting the president had requested that $36 billion be appropriated for the nuclear loan guarantee program.

The loan guarantee program has come under fire from all sides, with Congressional Republicans, questioning whether the department has spent its money wisely and moving to cut funding for the $71 billion program.

An audit released last week by the Energy Department’s inspector general found that poor record-keeping made it difficult to evaluate some loan decisions.  This is especially concerning when considering the high capital cost and high default rate of nuclear projects both here at home and internationally.

NRG’s South Texas Project (STP) proposed expansion near Bay City, TX is high on the list of projects being considered for a federal loan guarantee under this program.  Many of NRG’s financial partners on this project, Toshiba, Tepco (the operators of the doomed Fukushima Dai-ichi plant) and the Japanese government (through loan guarantees)  are probably looking at considerable contraints in being able to make substantial financial investments in projects outside of Japan for the foreseeable future.  Taxpayers should be concerned about issues with loan guarantee program’s ability to adequately assess the risks of their loan decisions.

The U.S. should immediately halt subsidies and instead focus on developing solar and wind power.

Take Action on Nuclear Subsidies

The administration must take off the blinders, look hard at what is going on in Japan and realize that yes, a catastrophe can happen here.

Back in January, Texans For A Sound Energy Policy (TSEP) filed formal legal contentions with the Nuclear Regulatory Commission (NRC) urging denial of Exelon’s application for an Early Site Permit (ESP) for a proposed nuclear power plant site south of Victoria, Texas.

Yesterday, TSEP appeared at a hearing before a three-judge panel of the Atomic Safety & Licensing Board (ASLB) to press its legal and scientific arguments.  This is the first NRC proceeding since onset of the ongoing Japanese nuclear disaster. 

TSEP argued that nuclear power is a high risk, high stakes business, and that the events in Japan must be paramount in the board’s determination of the suitability of the site for the construction of one or more nuclear power reactors – a determination that includes both safety concerns and environmental impact concerns.  TSEP believes that this site is neither safe nor environmentally acceptable and that the key to preventing nuclear and environmental disasters is to address site selection honestly, openly and comprehensively.

From a safety perspective, TSEP has raised four proposed contentions and noted, from the outset, their concerns with the cavalier attitude of Exelon, and a process that appears designed to deliberately obscure key safety issues regarding the site from the public.

TSEP said that their perception is that Exelon believes that it does not matter if there is faulting, hundreds of oil and gas wells, toxic gas and methane and inadequate water supply as long as the power block itself is not directly affected.  Additionally, there is a total disdain for any instability and uncertainty of the geologic platform for the proposed facility which is silt and clay riddled by fractures and oil and gas penetrations.  That coupled with the fact that there is co-location with toxic and explosive gas  poses potential dangers to the safe operation of a nuclear

TSEP believes good engineering can address many potential safety issues, but that we cannot engineer around issues that are not recognized, studied and evaluated.

In light of what the Fukushima Dai-ichi plant is dealing with, water – which has been a major environmental concern – now shows itself to be a major safety issue.  According to Jim Blackburn, the attorney representing TSEP,

Exelon’s proposed plan includes a cooling pond that is clearly crossed by two and potentially four subsurface faults.  These faults clearly threaten the stability of the cooling pond.  Exelon does not deny this but instead argues that it does not matter if the cooling pond fails because it is not a safety feature.  It seems that the Japanese situation suggests that a reserve supply of water may in fact be a major safety issue.  Without the salt water to pour on the core as a last resort, the situation in Japan would already have been worse.  There is no such fall-back plan here.  The cooling pond would function as a last resort facility, but it may in fact be breached and drained, assuming sufficient water to fill the pond at all.

We hope the NRC will slow some of these license approvals and re-licensing applications down until they have had time to evaluate what worked and what didn’t work when backup systems fail. 

The ASLB will be reviewing and deciding which contentions put forth by TSEP will be heard in a licensing hearing later this year.

The tragic events unfolding in Japan demand a re-examination of U.S. nuclear policy.  While stocks in nuclear plummet and nuclear industry lobbyists scramble on Capitol Hill to shore up support for massive federal subsidies to kick-start the stagnate industry, concerns regarding the existing aging fleet are surfacing and should be heeded.  Click here to read more about specific concerns about some of the aging US nuclear fleet.

Amazingly, despite emerging concerns about existing and proposed reactors, the Obama administration has said it will not back off its plans to further prop up the nuclear industry through increased taxpayer-backed loan guarantees and the inclusion of nuclear power technology in the administration’s clean energy standard. The administration has included $36 billion in loan guarantees in its budget proposal for fiscal year 2012. Instead, it should immediately halt subsidies and instead focus on developing solar and wind power.  Take Action on Nuclear Subsidies

According to an update from the Nuclear Information and Resource Service (NIRS) an explosion has occurred at Fukushima Daiichi Unit 1.

[youtube=http://www.youtube.com/watch?v=jMEV-_X5b_8]

Video of the aftermath of the explosion shows that the containment building
has been destroyed.

[youtube=http://www.youtube.com/watch?v=ELR3hdlce2g]

The NIRS update goes on to explain, in a General Electric Mark I reactor, the containment building is fairly weak and is considered the secondary containment. The primary containment is a steel liner that surrounds the reactor core. So far, video and photos have not been clear enough for us to determine whether this steel liner is intact.

Radiation levels at the site are reported to be 1,015 micro/Sieverts per hour. This is roughly equivalent to 100 millirems/hour. The allowable annual dose for members of the public from nuclear facilities in the U.S. is 100 millirems/year. The allowable annual dose for nuclear workers is 5,000 millirems/year. The average annual background dose from all radiation sources in the U.S. is about 360 millirems/year.

The explosion in Unit 1 was almost surely a hydrogen explosion. Pressure has been building up in the containment since offsite power was lost to the reactor because of the earthquake/tsunami. The GE Mark I reactor design is called a “pressure suppression” design. Rather than be built to withstand large pressure increases, General Electric sought with this design to attempt to reduce such increases in an accident scenario. The design has been criticized by independent nuclear experts and even Nuclear Regulatory Commission staff for many years (see: http://www.nirs.org/factsheets/bwrfact.htm).  In this case, the design clearly did not work. 24 U.S. reactors use the GE Mark I design.

The evacuation zone around the site has been expanded to 20 kilometers (about 12 miles). Another reactor at Fukushima Daiichi, Unit 2, is reported to be without cooling capability at this time. Three reactors at the nearby Fukushima Daini site are reported to be without cooling capability. These are GE Mark II designs, which are considered a mild improvement over the Mark I design. Both sites are on the Pacific Ocean, about six miles apart.

This morning’s quake on the other side of the world has implications for nuclear plants here in the U.S.   The Nuclear Regulatory Commission (NRC), through its regional office in Arlington, TX, announced they are closely monitoring this situation – the Japanese earthquake and subsequent tsunami – as it unfolds with respect to nuclear facilities within the United States.

Earlier today the NRC issued a “notice of unusual event” (NOUE) at the Diablo Canyon Power Plant, located near San Luis Obispo, CA.  In addition to the Diablo Canyon plant, the NRC is also monitoring the San Onofre nuclear power plant, the Humboldt Bay spent fuel storage site and NRC-regulated nuclear materials sites in Hawaii and Alaska to name a few.

A push to build new nuclear facililties in the U.S. has catapulted the nation’s aging nuclear industry into the limelight and the NRC is being quick to assure the public that nuclear power plants are engineered to withstand environmental hazards, including earthquakes, tsunamis and other natural disasters.

The NRC claims plants are designed to take into account the most severe natural phenomena historically reported for the site and surrounding area.  Still, while the emergency situation at two Japanese plants is seemingly contained at this point, with one Texas plant situated on the hurricane prone Texas Gulf coast and the other in the middle of tornado alley, one has to wonder . . . what if we haven’t yet seen the most severe natural phenomena for those areas?

The Atomic Safety and Licensing Board (ASLB) will hear oral argument relating to the Victoria County Station Early Site Permit (ESP) proceeding on March 16-17 in Victoria, Texas.

The ASLB is the independent body within the NRC that presides over hearings where the public can challenge proposed licensing and enforcement actions.

Oral arguments will begin at 9 a.m. CDT on Wednesday, March 16, in the Theatre Victoria at the Leo J. Welder Center for the Performing Arts, 214 N. Main St. in Victoria. The session will continue at 9 a.m. CDT on March 17. The session is open for public observation, but participation will be limited to authorized representatives of the groups taking part in the proceeding (Texans for a Sound Energy Policy [TSEP], the applicant – Exelon Nuclear Texas Holdings – and NRC staff involved in the proceeding).

Early arrival is suggested to allow for security screening for all members of the public interested in attending. NRC policy prohibits signs, banners, posters or displays in the hearing room.

Exelon submitted an ESP application March 25, 2010, seeking approval of the Victoria County Station site, which is approximately 13 miles south of Victoria. The ASLB is considering whether to grant TSEP intervenor status. The group has submitted several objections, or contentions, challenging Exelon’s application. The ASLB will hear oral argument on whether TSEP’s contentions meet the NRC’s requirements to be admitted for hearing under the NRC’s jurisdiction.

Documents related to the Victoria County Station ESP application are available on the NRC Web site at: http://www.nrc.gov/reactors/new-reactors/esp/victoria.html .

Documents pertaining to the ASLB proceeding are available in the agency’s electronic hearing docket at: http://ehd1.nrc.gov/EHD .

PUBLIC MEETING FEB. 24 TO DISCUSS REVISIONS TO KEY NRC DOCUMENT ON
CLASSIFICATION OF LOW-LEVEL RADIOACTIVE WASTE

The Nuclear Regulatory Commission will hold a public meeting Feb. 24 in Rockville, Md., to discuss potential revisions to a key document used by agency staff in classifying low-level radioactive waste for disposal.

The agency is also seeking written public comment on revisions to the document, known as the Branch Technical Position on Concentration Averaging and Encapsulation (CABTP).  (Yeah, I have no idea what that means either, but I do know that there are plans afoot to bring a whole lot of low-level radioactive waste to Texas so we should probably pay attention to what is classified as low-level radioactive waste)

The public meeting will be held at the Legacy Hotel Meeting Rooms, 1775 Rockville Pike, Rockville, Md., from 8 a.m. to 5 p.m. on Feb. 24. Public comments will be accepted through April 15.
