Content:
es assurance that an EDELS failure in one unit will not propagate to other units of the site. 4. GDC 17 requires an onsite electric power system for the functioning of SSCs important to safety. GDC 17 requires that the onsite electric power system have sufficient independence and redundancy for safety functions, assuming a single failure. GDC 17 requirements provide assurance that electric power will be available for systems necessary (i) to prevent fuel damage in the event of anticipated operational occurrences and (ii) to maintain core cooling and containment integrity in postulated accidents. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. 9.5.7-7 Revision 3 - March 2007 These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. For reviews under 10 CFR Part 50, the procedures below 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 verify whether the initial design criteria and bases are implemented appropriately in the final design as set forth in the final SAR. The OL review determines whether the content and intent of the applicant’s technical specifications agree with the requirements for system testing, minimum performance, and surveillance developed as a result of the staff’s review as indicated in subsection I of this SRP section. 2. For review of a DC application, the reviewer should follow the procedures to verify that the design, including requirements and
