Attachm:nt to PLN-254 ENVIRONMENTAL QUALIFICATION OF SAFETY RELATED ELEC'1RICAL EQUIPMENT Description Several aspects of equipment qualifications will be pursued by the NRC Staff and the nuclear industry on a generic basis, in order to achieve a more uniform implementation of requirements established in IEEE Standard 323-1974. Generic Task A-24 involves the development of the NRC's Interim Staff provisions with regard to how the requirements of IEEE Standard 323-1974 can be met.
Resolution As presented in Sections 3.11, 7.1 and 8.3 of the S/HNP PSAR and in Sections 3.11 and 7.1 of the 251 NSSS GESSAR which is incorporated as part of the S/HNP PSAR, S/HNP Class IE equipment qualification is based on IEEE 323-1974.
The commitments outline program described in the aforementioned sections are found to be acceptable by the NRC in Section 3.11 of the Skagit SER, NUREG-0309, September, 1977.
The NRC has issued a proposed rule, " Environmental Qualification of Electrical Equipment for Nuclear Power Plants" in the Federal Register on January 20,1982 at pp. 2,876-2,879.
The comment period for the proposed rule expires March 22, 1982 indicating that the final rule can be anticipated to be published in a timely manner with incorporation in the S/HNP equipment qualification efforts. The environmental qualifications of electrical equipment for the S/HNP will comply with the requirements of the final rule, and the details of the qualification program will be described in the appropriate sections of the S/HNP FSAR.
A description of S/HNP conformance to the final rule will be presented in the appropriate sections of the S/HNP Final Safety Analysis Report.
