e shutdown earthquake. Application of GDC 2 and RG 1.29 to the RCPB leakage detection system ensures that plant operators have the capability to detect and respond to RCPB leakage after an earthquake. The prompt detection of, and response to, RCPB leakage after an earthquake reduces the possibility of a severe loss-of-coolant accident. 2. GDC 30 requires that systems be provided for detecting and, to the extent practical, identifying the location of the source of reactor coolant leakage. The RCPB leakage detection system detects and identifies RCPB leakage. RG 1.45 describes acceptable methods for implementing GDC 30 with respect to the selection of RCPB leakage detection systems. Compliance with GDC 30 and the guidance in RG 1.45 ensure that operators have an early indication of RCPB degradation, thus minimizing the likelihood that an RCPB leak may go undetected and result in a severe loss-of-coolant accident. 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. For the construction permit review, the review should 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 an operating license review, the review should verify whether the initial design criteria and bases are implemented appropriately in the final design as set forth in the final SAR. Upon request from the primary reviewer, the coordinating reviewers provide input for the areas of review stated in subsection I of this SRP section. The primary reviewer uses such input as required to
