Content:
14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. 9. For reviews under 10 CFR Part 50, the procedures are used during the construction permit review to determine whether the design criteria and bases and the preliminary design as set forth in the preliminary SAR meet the acceptance criteria of subsection II of this SRP section. For the review of operating license (OL) applications, the procedures are used to determine whether the initial design criteria and bases are implemented appropriately in the final design as set forth in the final SAR. OL review procedures include a determination whether the content and intent of the applicant’s technical specifications agree with the requirements for system testing, minimum performance, and surveillance developed in the staff review as indicated in subsection I of this SRP section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. 1. The EDECWS includes all piping, valves, heat exchangers, and pumps up to the points where the cooling water piping connects to the engine interfaces. The EDECWS scope of review for the plant included layout drawings, process flow diagrams, piping and instrumentation diagrams, and descriptive information for the system and auxiliary supporting systems essential to its operation. EDECWS essential portions necessary to mitigate the consequences of an accident are designed to seismic Category I and quality Group C. The basis for EDECWS acceptance in our review was compliance of the designs, design criteria, and bases with NRC regulations as set forth in the GDCs of Appendix A to 10 CFR Part 50. The staff concludes that the plant design is acceptable and meets
