these requirements. Meeting 10 CFR Part 50, Appendix B, Criterion XVII provides assurance that identifiable and retrievable records are maintained to furnish evidence of activities affecting quality, which includes environmental design and qualification. 10. In Staff Requirements Memorandum SECY-05-0197, “Review of Operational Programs in a Combined License Application and Generic Emergency Planning Inspections, Tests, Analyses, and Acceptance Criteria,” dated February 22, 2006, the Commission approved the use of a license condition for operational program implementation milestones that are fully described or referenced in the final safety analysis report. The 10 CFR 50.49 environmental qualification regulation for electrical and I&C equipment located in a harsh environment was identified as an operational program in that memo. III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. For each area of review specified in subsection I of this SRP section, the review procedure is identified below. These review procedures are based on the identified SRP acceptance criteria. For deviations from these specific acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives to the SRP criteria provide an acceptable method of complying with the relevant NRC requirements identified in subsection II. 1. At the CP stage, the staff reviews the program that the applicant has described in the preliminary safety analysis report (PSAR) for the environmental design and qualification of the mechanical, electrical, and I&C equipment. The program is measured against the acceptance criteria listed in Subsection II of this SRP section. Of particular interest to the reviewer is the proper use of test and analytical procedures. Equipment should be tested unless testing of the component is impractical due to size limitations or partial type-test
