Nuclear Regulatory Commission.


Proposed rule: Extension of comment period.


On May 16, 2003 (68 FR 26511), the Nuclear Regulatory Commission (NRC) published in the Federal Register for a 75-day comment period proposed 10 CFR 50.69 “Risk-Informed Categorization and Treatment of Structures, Systems, and Components for Nuclear Power Plants.” The comment period for this proposed rule was to have expired on July 30, 2003. By letter dated July 3, 2003, Nuclear Energy Institute (NEI) requested a 30-day extension to the comment period. NEI indicated that this extension is to allow for the thorough review and refinement of comments developed by NEI's Option 2 task force and other constituents in the industry. In view of the importance of both the proposed rule and the industry's comments on it, the NRC has decided to extend the comment period by 30 days as requested.


The comment period has been extended and now expires on August 30, 2003. 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 on or before this date.
