Nuclear Regulatory Commission September 24, 2009 – Federal Register Recent Federal Regulation Documents

On August 10, 2009, the Nuclear Regulatory Commission (NRC) published for public comment a supplemental proposed rule that would amend the requirements that govern domestic licensing of production and utilization facilities and licenses, certifications, and approvals for nuclear power plants to allow current and certain future power reactor licensees and applicants to choose to implement a risk-informed alternative to the current requirements for analyzing the performance of emergency core cooling systems (ECCS) during loss-of-coolant accidents (LOCA). The proposed amendments would also establish procedures and acceptance criteria for evaluating certain changes in plant design and operation based upon the results of the new analyses of ECCS performance.
