Environmental Qualification of Electric Equipment

The Commission has undertaken a major initiative to answer questions related to the environmental qualification (EQ) of electric equipment in nuclear power plants, 10 CFR 50.49. In November 1993, the Office of Nuclear Regulatory Research held a public workshop to obtain technical input for the formulation of EQ research program. One of the recommendations made at this workshop was that the NRC staff should review all previous work in the EQ area and endeavor to have its research program cost effective without duplicating past efforts. The participants at the workshop stated that the focus of the NRC's attention should be on components such as cables and electrical penetrations, that are long lived and very burdensome to replace. The NRC staff accepted these recommendations and the current research efforts are limited to EQ issues pertaining to cables. In this context, the staff plans to review approximately 300 EQ documents (test reports, technical papers and reports, etc.). The listing of these references is available in the NRC Public Document Room. The staff is seeking public input to determine the completeness of this list of references.
