unguarded lines, 'the CSB reviews analyses of the consequences of postulated ruptures in these lines. The CSB bases its acceptance of the analyses on the conser- vatism of the methods and assumptions and on the margin provided to assure against exceeding the design pressure of the containment. If leakage detection and isolation equipment are provided, the ICSB evaluates the effectiveness of the detection instrumentation and isolation devices to mitigate the consequences of a pipe rupture and the electrical design criteria for these systems under SRP Section 7.3. 4. The CSB reviews the analyses of the suppression pool temperature for transients involving the actuation of reactor coolant system safety/relief valves in Mark I, II and III plants. The CSB evaluates the assumptions and conservatisms employed in the analyses to assure that the acceptance criteria set forth in NUREG-0783 are met. The CSB also reviews the proposed reactor coolant system safety/relief valve in-plant confirmatory test programs or the rationale for not per- forming such tests. 5. The CSB evaluates analyses of bypass leakage capability. The CSB deter- mines 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. CSB will advise the AEB of the bypass leakage. 6. The CSB evaluates the conservatism of potential depressurization transients. In evaluating surveillance and test programs for vacuum relief systems, the CSB uses the results of previous reviews and operating experience with similar systems to determine their adequacy. At the operating license stage, the SSPB reviews the proposed technical specifications to assure 6. 2.1. 1.C-7 Rev. 6 - August 1984 that adequate surveillance and administrative control will be maintained over the vacuum relief devices. 7. Upon request, the SEB will review the design of unique flow-limiting devices which are identified during the CSB
