Content:
ould increase risk under existing or imminent degraded grid reliability conditions, including: (1) conditions that could increase the likelihood of a plant trip, (2) conditions that could increase the likelihood of LOOP or SBO, and (3) conditions that have an impact on the plant’s ability to cope with a LOOP or SBO, such as, out-of-service risk- significant equipment (e.g., an EDG, a battery, a steam-driven pump, and alternate ac power source). 12. For reviews of DC and COL applications under 10 CFR Part 52, the reviewer should follow the above procedures to verify that the design set forth in the safety analysis report, and if applicable, site interface requirements meet the acceptance criteria. For DC applications, the reviewer should identify necessary COL action items. With respect to COL applications, the scope of the review is dependent on whether the COL applicant references a DC, an ESP or other NRC-approved material, applications, and/or reports. After this review, SRP Section 14.3 should be followed for the review of Tier I information for the design, including the postulated site parameters, interface criteria, and ITAAC. 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. The offsite power system includes two or more identified circuits from the grid and its transmission lines to the onsite distribution system. The review of the offsite power system for the __________ plant covered single-line diagrams, station layout drawings and schematic diagrams, and descriptive information. The basis for acceptance of the offsite power system in our review was conformance of the design criteria and bases to the Commission's regulations as set forth in the General Design Criteria of Appendix A to 10 CFR Part 50.
