Opposing Group Says Nuclear Reactor Design Has Corrosion Risks

An anti-nuclear coalition says design flaws in Westinghouse’s AP1000 reactor could allow radiation leaks during an accident, and it is calling on federal authorities to suspend licensing and loan guarantees for plants that use it.

The AP1000 Oversight Group (PDF, 12k), made up of 11 environmental organizations, released a report (PDF, 4.46M) Wednesday detailing what it calls a serious safety issue that the Nuclear Regulatory Commission has not addressed on the AP1000 reactor.

The report contends Westinghouse designed the reactor without a corrosion-proof backup to protect against leaks from the containment vessel. In a reactor accident, the reactor’s safety systems would allow any radioactive material that had leaked over time to be released into the air and spread to nearby populated areas, the group contends.
