sults with other branches as necessary to be assured that the proper environmental parameters are being used for the equipment qualification. 3.11-15 DRAFT Rev. 3 - April 1996 For each area of review, the following procedures are used: (1) At the CP stage, the staff reviews the program which the applicant has described in the preliminary safety analysis report (PSAR) for the environmental qualification of the 123 mechanical and electrical equipment. The program is measured against the requirements listed in subsection II. Of particular interest to the reviewer areis the proper use of test 124 and analytical procedures. Equipment should be tested unless testing of the component is impractical due to size limitations or partial type-test data areis provided to support the analytical assumptions and conclusions reached. The qualification is reviewed for the identification of normal, abnormal, accident, and postaccident environmental conditions; anticipated operational occurrences; required operating time; and chemical, and submergence, aging, and margin considerations, including the acceptance criteria of the test results.125 (2) At the OL stage, the staff reviews the program again as described by the applicant in the FSAR. In addition, the FSAR is reviewed for documentation of the successful implementation of the environmental qualification program, including test and analytical results. The reviewer verifies that the applicant's list of systems, which includes the list of equipment associated with each such system, is consistent with the definition of the systems and equipment as delineated in paragraph 1 of subsection Idescribed in the second paragraph of subsection I.126 To confirm the extent to which the equipment meets the requirements of subsection II, the staff audits the equipment qualification file and conducts a plant site review. For selected equipment, the staff reviews the test procedure and test results, and examines the equipment configuration and
