Generation III nuclear reactors: late again | Greenpeace International - 0 views

  •  
    "Yesterday we brought you more of the continuing and farcical story of the state of the art European Pressurised Reactor (EPR) being built by AREVA at Olkiluoto in Finland. The many, many diverse delays incompetence in the project have led to it being (at the time of writing) four years behind schedule and 2.3 billion euros over-budget.

    It's not just in Finland, however, where the reactor that was supposed to relaunch the nuclear 'renaissance' is struggling. In the UK, where the EPR - along with the Westinghouse AP1000 - is being evaluated for possible construction there, the government's Health and Safety Executive has said its design assessment process will miss its June 2011 deadline.

    More information is required from the reactor vendors in a number of areas: fault studies, fuel design and electrical systems for AP1000; and mechanical engineering, environment and fuel design for the EPR. For both reactors the HSE wants more information on structural integrity as well as higher active waste and used fuel management."

NRC to Meet With Toshiba on Nuclear-Reactor Design (Correct) - Bloomberg.com - 0 views

  •  
    U.S. Nuclear Regulatory Commission staff will meet with Toshiba Corp. next week to discuss the safety of its proposed AP1000 nuclear-reactor design.

    Toshiba's Westinghouse unit will address the commission's concern about the structural integrity of the silo-shaped shield building that would contain the reactor and trap radioactivity in an accident, NRC Chairman Gregory Jaczko said today in an interview at Bloomberg's New York bureau.

    Containment buildings at existing reactors were poured at the site as a solid piece of steel-reinforced concrete, Jaczko said. Toshiba wants to piece the building together from sections, he said.

    "Where the staff has some concerns is how those things are tied together," Jaczko said. "When you're dealing with the kinds of accident scenarios that we look at, or hurricanes or tornados or seismic events, will that structure maintain its integrity?"

    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.

NRC orders changes in reactors set for S.C. - Local / Metro - The State - 0 views

  •  
    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.

Westinghouse Statement Regarding NRC News Release on AP1000(TM) Shield Building - 0 views

  •  
    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.

Bellefonte not picked for nuclear pilot project - al.com - 0 views

  •  
    NuStart Energy Development has picked a Georgia nuclear plant over the Bellefonte site near Scottsboro as its pilot project for a new generation of reactors.

    But the Tennessee Valley Authority said it will continue pursuing federal approval to build and operate Units 3 and 4 at the Bellefonte Nuclear Plant.

    TVA said Thursday that NuStart "is transferring the reference designation" to build two Westinghouse AP1000 reactors from Bellefonte to Southern Co.'s Plant Vogtle site near Waynesboro, Ga.

    "The change," it said, "is designed to align industry and regulatory resources with a license application that has specific, near-term construction plans."

    Atlanta-based Southern, parent of Alabama Power, anticipates getting a license to build and run the two new reactors in 2011 and having them online by 2016. TVA is looking at getting a license for Bellefonte in 2012 and having its two units ready by 2018. The Nuclear Regulatory Association must approve all new reactors.

    Public unable to get information to assess safety, viability, critics say

    NASHVILLE - The electric industry's effort to fast-track a new design for nuclear reactors has triggered complaints about transparency and questions about the suitability of a TVA site in Alabama.

    Just over a year ago, the Tennessee Valley Authority, backed by a consortium of other electric utilities, applied for a license to build along the Tennessee River the first of a new generation of nuclear reactors.

Standardized nuclear plant design eluding utility firms - Triangle Business Journal: - 0 views

  •  
    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.

Westinghouse signs agreements on AP1000 construction in UK - 0 views

  •  
    Westinghouse Electric Co. said it signed separate agreements September 4 with three companies to collaborate on work for construction in the UK of its AP1000 reactor design. In a September 4 press statement, Westinghouse said the agreements ? with BAE Systems, Rolls-Royce and Doosan Babcock -- may lead to the UK supply chain providing 70%-80% of the services required to build the AP1000.
