Nuclear Regulatory Commission March 7, 2005 – Federal Register Recent Federal Regulation Documents

The Nuclear Regulatory Commission (NRC) proposes to amend its fire protection regulations for nuclear power facilities operating prior to January 1, 1979. The amendment would allow nuclear power plant licensees to use manual actions by plant operators as an alternative method to achieve hot shutdown conditions in the event of fires in certain plant areas, provided that the actions are evaluated against specified criteria and determined to be acceptable and that fire detectors and an automatic fire suppression system are provided in the fire area. The Commission believes that the proposed action would provide realistically conservative regulatory acceptance criteria for operator manual actions to achieve and maintain hot shutdown condition. The NRC is also proposing and requesting comments on a draft regulatory guide to support this proposed rulemaking. The NRC has developed the Regulatory Guide Series to describe and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses. The draft regulatory guide, entitled ``Demonstrating the Feasibility and Reliability of Operator Manual Actions in Response to Fire,'' is temporarily identified by its task number, DG-1136, which should be mentioned in all related correspondence. This proposed regulatory guide offers guidance for NRC licensees and applicants to use in implementing the feasibility and reliability criteria that the staff developed for post-fire operator manual actions.
