.49, as applicable, and specifying the duration of which its function is required. The staff also reviews the applicant’s determination of the required functional duration for equipment important to safety, and the associated bases. For a COL applicant, the staff reviews the incorporation by reference of the environmental qualification provisions for mechanical, electrical, and I&C equipment important to safety in the design certification DCD/FSAR. The staff also reviews the description of the COL program provided by the applicant for the site-specific environmental qualification for electrical, mechanical, and I&C equipment important to safety. 6. The NRC regulations in 10 CFR 52.47, “Contents of Applications; Technical Information,” state that the Commission will require, before design certification, that information normally contained in certain procurement specifications and construction and installation specifications be completed and available for audit if the information is necessary for the Commission to make its safety determination. The staff performed design specification audits for all design applications to verify that EQ requirements were properly translated into the design specification. Based on the results of these audits, staff finds it necessary to perform these audits in order to make a safety finding. Therefore, the staff will conduct an audit of the procurement specifications as discussed in the introduction of 10 CFR 52.47 for the environmental qualification of mechanical and electrical equipment. This audit could be conducted as part of the review of the COL application if NRC staff review of the design certification application and initial COL application are underway at the same time. 7. Operational Program Description and Implementation. For DC and COL applications the staff reviews the full description of the environmental qualification operational program consistent with the guidance in SECY-05-0197. The staff also reviews FSAR
