ollowing an international tendering process, the team of companies headed up by AREVA TA (Paris:CEI) was awarded a contract to design a near surface repository for low and medium level waste on the Ignalina nuclear power plant site in Lithuania. The project, funded primarily by the EBRD, includes the design studies for the repository and on-site support during construction. The repository will receive low and medium level operational waste recovered from the dismantling of the Lithuanian power plant. As part of AREVA's Reactors and Services division, AREVA TA has extensive experience in the design of such facilities for radioactive waste, or in providing support to projects for their design and construction. Other team members include the French national radioactive waste management agency ANDRA, which will provide its expertise in this field, the Lithuanian Energy Institute (LEI), which brings experience in safety an environmental assessment, and knowledge on national regulations, the company Specialus Montazas-NTP (SM-NTP), which contributes skills in geology, civil engineering, seismic design and mechanical design, and the company Pramprojektas (PP), which brings infrastructure know-how.

The Nuclear Regulatory Commission raised safety concerns Thursday with the design of a proposed next-generation reactor to be built by Westinghouse Electric Co., saying a key part of the reactor may not withstand a tornado, earthquake or even high winds. The NRC staff directed Westinghouse to make changes in the reactor design so that its outer shell, which is supposed to protect the reactor's concrete containment structure, is strengthened. The staff concluded the outer steel and composite structure does not meet the design requirements for safety. The reactor, called the AP1000, is one of three next-generation reactor designs under NRC review. The others are being proposed by Areva Inc., the French nuclear company, and GE Hitachi Corp. But the AP1000 is one of the most popular and has been widely viewed as likely to be the first of the new reactors to be built in the United States. At least seven utilities have selected the reactor design in preliminary applications filed with the NRC, anticipating the potential construction of 14 units.

Interim assessment reports for two nuclear power station designs being considered for construction in the UK have been made public today. The Health and Safety Executive (HSE) has published the reports on Step 3 of its Generic Design Assessment of the designs put forward by EDF/AREVA and Westinghouse. The GDA process enables the HSE and the Environment Agency (EA) to assess new nuclear power station designs before an application for a site licence has been received. The reports concerning EDF/AREVA's EPR design and Westinghouse's AP1000 reflect progress to date and highlight issues to be resolved during the next phase, a detailed assessment which will conclude in June 2011.

The Tennessee Valley Authority continues its way on a troubling path of the unknown with nuclear power plants. Given all the potential ramifications of flaws at any nuclear power facility, the public has good reason to question the path taken by TVA. Among the most recent concerns about TVA operations are questions about the design for potential new nuclear reactors at the Bellefonte nuclear power site near Huntsville, Ala. TVA is seeking a license to build a plant based on a new design, the AP-1000 Westinghouse, but environmental groups say while the licensing process goes forward changes are being made to the design. Advertisement TVA insists the changes in the design are only peripheral to the basic plan. Design changes include changes to the pressurizer; changes in the seismic analysis involving rock and soil conditions; changes in instruments and a redesign of fuel racks. Advocates of the licensing process say the design changes at issue are only the kinds of items that can be carried easily on a parallel track with the application process. The basic design is said to be a simpler version of a nuclear reactor. The design is significant because if and when it is approved for Bellefonte, it streamlines the process for other plant sites that might want to build on a Bellefonte model.

The U.S. NRC has informed Westinghouse that the proposed design of the shield building for its AP1000(TM) nuclear power plant will require either additional analysis, testing or actual design modifications to ensure compliance with NRC requirements. As a result of our understanding of the requirements, Westinghouse fully expected that the NRC would require additional analysis, testing or actual design modifications to the shield building. In fact, we had already begun to address certain portions of the design. We have fully committed the resources necessary to both quickly and definitively address the NRC's concerns, and we are confident that we will meet all applicable requirements. Westinghouse continues to work toward our goal of receiving Design Amendment Certification from the NRC in 2011, and we continue to work to bring the first AP1000s online in the United States in the 2016 timeframe.

Work to remove 16 million tons of radioactive waste away from the tourist town of Moab is about to go a little faster. The U.S. Department of Energy says it plans to double the amount of uranium tailings removed each day from the shores of the Colorado River. Right now, rail cars take about 2,800 tons of tailings a day to a dump site 30 miles away, where they're placed in specially designed cells. The DOE says a second train will be added in mid-August.

The Nuclear Regulatory Commission staff has informed Westinghouse that the company has not demonstrated that certain structural components of the revised AP1000 shield building can withstand design basis loads. An NRC letter to Westinghouse states that progress on the shield building review will require the company to provide modifications to the design, as well as testing that demonstrates the building will perform its intended safety function under design basis loads. The staff will continue its review of the remainder of the AP1000 design certification amendment application. As the name implies, the AP1000 shield building would protect the reactor's primary containment from severe weather and other events. The building's other functions would include providing a radiation barrier during normal operation and supporting an emergency cooling water tank. "We've been talking to Westinghouse regularly about the shield building since October 2008, and we've consistently laid out our questions to the company," said Michael Johnson, director of the NRC's Office of New Reactors. "This is a situation where fundamental engineering standards will have to be met before we can begin determining whether the shield building meets the agency's requirements."

Westinghouse vows to fix all the issues raised by regulators SCOTTSBORO - Westinghouse's failure to show that a shield building for a proposed nuclear plant near Scottsboro is structurally safe is "the tip of the iceberg of problems that lie ahead" for the project, said Lou Zeller, director of the Blue Ridge Environmental Defense League. Zeller said Friday that cracks could cause the steel and concrete buildings housing a nuclear reactor to leak into the air outside the plant. But Westinghouse spokesman Scott Shaw said that the plant "wouldn't be licensed" if that were the case. Zeller said containment buildings at older nuclear plants are "showing signs of wear and tear," including cracks. But Shaw said Westinghouse designed a concrete building with steel plates to prevent any leaks, instead of steel-reinforced bars used in previous nuclear plant designs. The Nuclear Regulatory Commission on Thursday informed Westinghouse, designer of the AP1000 plant proposed at the Tennessee Valley Authority's Bellefonte site, that it will need to modify its design.

RALEIGH - The nuclear plant design favored for new plants by Progress Energy, Duke Energy and three other utilities is the subject of multiple design changes that energy industry watchdogs say undermine the concept of a pre-certified design and could delay the construction of new reactors while adding billions to the cost. The Nuclear Regulatory Commission certified the plant design of Westinghouse Electric Co.'s AP1000 at the end of 2005. Pre-certification was intended to help streamline an approvals process that takes years before plant construction even begins.

The Nuclear Regulatory Commission is raising safety concerns a proposed new reactor designed by Westinghouse, two of which South Carolina Electric & Gas Co. and Santee Cooper plan to install at their existing plant north of Columbia. A key part of the reactor may not withstand a tornado, earthquake or even high winds, NRC said. The commission staff has directed Westinghouse to make changes in the reactor design so its outer shell, which protects the reactor's containment structure, is strengthened. The staff concluded the steel and concrete structure of the AAP-1000 reactor does not meet safety design requirements. SCE&G spokesman Robert Yanity said Thursday the redesign is not expected to affect the schedule of the South Carolina reactors, which are set to come online by 2016 and 2019, respectively. The project at the V.C. Summer nuclear station near Jenkinsville is projected to cost $10 billion. Utility officials hope to have a combined operating and construction license in hand by 2011.

"he nuclear reactor design that Florida Power & Light picked for its expansion at Turkey Point has safety flaws that its manufacturers and federal regulators have overlooked, according to a technical analysis commissioned by environmental groups. The report -- made public Wednesday -- contends that the reactor's steel-walled containment vessel, the protective barrier from radiation, is more vulnerable to developing rust and holes than older reactors. That, coupled with the design of its emergency cooling system, could multiply exposure risks in the event of an accident, the report concludes. Arnold Gundersen, a nuclear engineer who produced the report for a dozen national and regional environmental groups, said during a teleconference that the AP 1000 design by the Westinghouse Electrical Co. was ``entirely different'' from older designs and also ``inherently less safe.'' "

Officials with the U.S. Nuclear Regulatory Commission and the Tennessee Valley Authority said they are unsure how long a proposed AP1000 nuclear plant near here could be delayed after Westinghouse failed to show that certain parts of a shield building can withstand design basis loads. "Obviously, it won't make it shorter," TVA spokesman Terry Johnson said this afternoon. NRC spokesman Roger Hannah said in a phone interivew that the shield building encloses the containment building, which contains the reactor. In a press release issued this afternoon, the NRC said it informed Westinghouse, the designer of the AP1000 proposed for Bellefonte Nuclear Plant, "that it has not demonstrated that certain structural components of the revised...shield building can withstand design basis loads."

Watchdog warns £20bn programme faces delay unless reactor designers improve performance The UK's £20bn nuclear programme is facing delays because of a failure to tackle design problems with their reactors, the Health and Safety Executive has warned. A report by the HSE, seen by Building, said the two firms in the running to build the reactors had to put more resources into dealing with the safety assessment process if it was to be completed on time. One of them, Japanese-owned Westinghouse, came in for particular criticism for failing to provide a report on external hazards such as flooding.

Designs for new nuclear power stations that could be built in this country will be under public scrutiny from today. EU law requires that before any new nuclear power station is built, their designs must be 'Justified'. This involves a generic assessment to determine whether the overall benefit of the practice of ionising radiation outweighs any associated health detriment. Minister of State for Energy and Climate Change Mike O'Brien said: "This Justification process is yet another example of the facilitative actions the government is taking to support new nuclear power in the UK. At the same time it gives people the opportunity to have their say on the benefits and detriments of the practices involved."

The Nuclear Regulatory Commission has made available to the public the combined license (COL) application for a new reactor at the River Bend site near Baton Rouge, La. The applicant, Entergy, submitted the application and associated information Sept. 25. The application, minus proprietary or security-related details, is available on the NRC Web site at: http://www.nrc.gov/reactors/new-reactors/col/river-bend.html. The Entergy application seeks approval to build and operate an Economic Simplified Boiling Water Reactor (ESBWR) at the site, approximately 24 miles northwest of Baton Rouge. The ESBWR is a General Electric-designed, 1,500 MWe natural-circulation boiling water reactor that incorporates passive safety systems. The NRC is currently reviewing the design for possible certification. More information on this design is available on the NRC Web site at: http://www.nrc.gov/reactors/new-reactors/design-cert/esbwr.html.

As part of India's strategic programme, the Bhabha Atomic Research Centre (BARC) has developed fourth generation uranium enrichment gas centrifuges with an output of more than 10 times the earlier design, a top BARC official has said. "An experimental cascade of the fourth generation design is in operation at BARC and will soon be ready for induction at the Rare Materials Plant (RMP) in Ratnahalli near Mysore," BARC director Sreekumar Banerjee said addressing the Founder's Day celebration yesterday. "The Third generation design with 5 times more output than earlier designs are presently being inducted at RMP," he said.

GE Hitachi Nuclear Energy said on Wednesday it has submitted the revised design documents for its Economic Simplified Boiling Water Reactor (ESBWR) to the U.S. Nuclear Regulatory Commission. GE Hitachi said the submission marks a milestone in the company's effort to move forward with the 1,520-megawatt design which two U.S. utilities have selected to use for two new nuclear plants, some of the first reactors proposed after a three-decade lapse in U.S. nuclear expansion. Two other U.S. utilities dropped the ESBWR design fearing that the time needed to obtain NRC certification would slow their efforts to pursue construction of new reactors.

The Nuclear Regulatory Commission has made available the public version of a combined license (COL) application for two new reactors at the Turkey Point site near Miami. The applicant, Florida Power & Light (FP&L), submitted the application and associated information June 30. The application, minus proprietary and security-related details, is available on the NRC Web site at: http://www.nrc.gov/reactors/new-reactors/col/turkey-point.html. FP&L's COL application seeks approval to build and operate two AP1000 reactors at the site, approximately 25 miles south of Miami. The AP1000 is a Westinghouse 1,100 MWe pressurized-water reactor design the NRC certified in 2006. Westinghouse submitted an application in May 2007 to amend the certified design. The design certification amendment application (minus proprietary and security-related details) is available on the NRC Web site at: http://www.nrc.gov/reactors/new-reactors/design-cert/amended-ap1000.html.
