This report provides the NRC staff positions regarding selected areas of environmental qualification of safety-related electrical equipment in the resolution of Generic Technical Activity A-24, Qualification of Class 1E Safety-Related Equipment. The positions herein are applicable to plants that are or will be in the construction permit (CP) or operating license (OL) review process and that are required to satisfy the requirements set forth in either the 1971 or the 1974 version of IEEE Standard 323.
