system flow and heat transfer requirements are met for each accident situation for the required time spans. For each case, the design will be acceptable if minimum system requirements are met. D. The boron recovery system is not required for safe shutdown, or for the prevention or mitigation of postulated accidents. The BRS will be reviewed for the following: if the system tankage is of nonseismic Category I design, the results of analyses which postulate the rupture of tanks are reviewed by AEBPERB to verify that the accident 60 releases are in accordance with safe limits. DRAFT Rev. 3 - April 1996 9.3.4-14 E. The reviewer confirms that the CVCS system's capability is sufficient with respect to the plant's ability to withstand or cope with, as applicable, and recover from, a SBO by determining compliance with Regulatory Guide 1.155 positions C.3.2, C.3.3.4, and C.3.5. This review is coordinated with the review of the SBO event under SRP Section 8.4 (proposed).61 For plants/applicants that do not submit adequate test data to demonstrate the integrity of the reactor coolant pump seals during a SBO for an extended period, the reviewer verifies that there are adequate means to provide RCP seal cooling during a SBO. A diverse seal injection system, that is independent of the CVCS and associated support systems to the extent practicable, is an acceptable approach. If a diverse seal injection system is proposed by the applicant, the reviewer verifies that the system can be powered from the alternate AC power source for station blackout.62 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II.
