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,
