NUCLEAR REGULATORY COMMISSION

10 CFR Part 50

RIN 3150-AH29

Risk-Informed Changes to Loss-of-Coolant Accident Technical Requirements; Extension of Comment Period

AGENCY: Nuclear Regulatory Commission.

ACTION: Proposed rule: Extension of comment period.

SUMMARY: On November 7, 2005 (70 FR 67598), the Nuclear Regulatory Commission (NRC) published for public comment a proposed rule amending its regulations to permit current power reactor licensees to implement a voluntary, risk-informed alternative to the current requirements for analyzing the performance of emergency core cooling systems during loss-of-coolant accidents. On December 6, 2005, the Nuclear Energy Institute (NEI) requested a 30 day extension to the comment period for the proposed rule. On December 20, 2005, the Westinghouse Owners Group submitted a letter endorsing the NEI extension request. The extension requests were based on the occurrence of two major holidays during the comment period which limited the time available to coordinate industry comments from owners groups, vendors, and licensees. The NRC is extending the comment period on the proposed rule by an additional 30 days from the original February 6, 2006 deadline until March 8, 2006. This comment period extension also applies to related public comments submitted on the NRC report on Seismic Considerations for the Transition Break Size (70 FR 75501).

DATES: The comment period has been extended and now expires on March 8, 2006. Comments received after this date will be considered if it is practical to do so, but the Commission is able to ensure consideration only for comments received before this date.

ADDRESSES: Mail written comments to: Secretary, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001. Attn: Rulemakings and Adjudications Staff.

Hand delivered comments should also be addressed to the Secretary, U.S. Nuclear Regulatory Commission, and delivered to: 11555 Rockville Pike, Rockville, MD, between 7:30 am and 4:15 pm Federal workdays.
