Content:
actuated equipment that is not tested during reactor operation, but it does not have provisions for excluding any portion of the protection system from the requirements of Clauses 4.9 and 4.10 of the Institute of Electrical and Electronics Engineers (IEEE) Standard (Std) 279-1971, “Criteria for Protection Systems for Nuclear Power Generating Stations,” or the safety system from the requirements of Clauses 5.7 and 6.5 of IEEE Std 603-1991, “IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations.” B. BRANCH TECHNICAL POSITION All portions of the protection and safety systems should be designed in accordance with IEEE Std 279-1971 or IEEE Std 603-1991, as required by Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(h), “Protection and Safety Systems.” All actuated equipment that is not tested during reactor operation should be identified, and a discussion of how each conforms to the guidance of paragraph D.4 of RG 1.22 should be submitted. In addition to conformance with the guidance in RG 1.22, the review of this topic should also confirm that the proposed design and the justification for test intervals are consistent with the surveillance testing proposed as part of the plant technical specifications. 1. The protection system should satisfy the requirements of the General Design Criteria and 10 CFR 50.55a(h) of 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities.” 10 CFR 50.55a(h) requires compliance with IEEE Std 603-1991, and the correction sheet dated January 30, 1995. For nuclear power plants with construction permits issued before January 1, 1971, the applicant or licensee may elect to comply instead with their plant-specific licensing basis. For nuclear power plants with construction permits issued between January 1, 1971 and May 13, 1999, the applicant/licensee may elect to comply instead with the requirements stated in IEEE Std 279-1971.
