Environmental design and qualification are activities that can affect quality; therefore, components in the scope of this section that are subject to environmental design and qualification must have identifiable and retrievable records that document the fact that they meet 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 SRM-SECY-05-0197, 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 memorandum. III. REVIEW PROCEDURES 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
