t system safety/relief valve in-plant 88 confirmatory test programs or the rationale for not performing such tests. 5. The SCSB evaluates analyses of bypass leakage capability. The SCSB determines the adequacy of proposed bypass leakage tests and surveillance programs based on the results of previous reviews, operating experience at similar plants, and engineering judgment. SCSB will advise the AEBPERB of the bypass leakage. 89 90 6. The SCSB evaluates the conservatism of potential depressurization transients. In evaluating surveillance and test programs for vacuum relief systems, the SCSB uses the 91 DRAFT Rev. 7 - April 1996 6.2.1.1.C-12 results of previous reviews and operating experience with similar systems to determine their adequacy. At the operating license or design certification stage, the TSBSSPB 92 93 reviews the proposed technical specifications to assure that adequate surveillance and administrative control will be maintained over the vacuum relief devices. 7. Upon request, the SEBECGB will review the design of unique flow-limiting devices 94 which are identified during the SCSB review of the containment subcompartments. 95 8. The SCSB reviews the accuracy and range of the instrumentation provided to monitor the post-accident environment. The ICSBHICB , under SRP Section 7.5, and the 96 EQBSPLB , under SRP Section 3.11, have review responsibility for the acceptability of, 97 and the qualification test program for, the sensing and actuation instrumentation of the 98 plant protection system and the postaccident monitoring instrumentation and recording equipment. 9. For new plant applicants, the containment analyses should also consider shutdown conditions, when appropriate, to ensure that a basis is provided for procedures, instrumentation, operator response, equipment interactions and equipment response during shutdown operations. The analyses should encompass shutdown thermodynamic states and physical configurations to which the plant can be subjected
