Content:
g compressed air capacity, when determining the plant’s capability to cope with a station blackout. RG 1.155, Position 3.3.3, provides guidance for the use of alternate compressed air sources if the compressed air capacity is not sufficient to cope with a station blackout. RG 1.155, Position 3.5, provides guidance for quality assurance and specifications for nonsafety-related equipment under 10 CFR 50.63 not already under 10 CFR Part 50, Appendix B quality assurance requirements. 10 CFR 50.63 and the positions of RG 1.155 on the ability to withstand, cope with, and recover from a station blackout provide additional defense in depth against unacceptable offsite consequences if both offsite and onsite emergency alternating current power systems fail concurrently. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. 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. 9.3.1-7 Revision 2 - March 2007 The procedures below during the construction permit review determine whether the design criteria and bases and the preliminary design as set forth in the preliminary SAR meet the recommendations and requirements of Subsection II of this SRP section. For operating license reviews, 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 procedures for operating license and DC reviews 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 from the staff’s review.
