ifying the following: a. The functional design of the ICAS, including air or nitrogen accumulators, is in accordance with its intended function. b. Air-operated component failure positions are correct for assuring required functions upon a sudden as well as a gradual loss of air pressure. c. Periodic testing leakage limits have been established that ensure air-operated components will function as intended for required durations. 92 For each case the design will be acceptable if minimum system requirements are met. 7. The reviewer verifies that ICAS systems and components important to safety are not shared among nuclear power units unless it is shown that such sharing will not impair their ability to perform their safety functions, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units.93 DRAFT Rev. 2 - April 1996 9.3.1-12 8. The reviewer determines whether the compressed air system could possibly become contaminated through interfaces with radioactive systems (e.g. contaminated due to leakage, valving errors or faulty operation in other radioactive systems, etc.). If the system could become contaminated, the reviewer ensures that there are provisions for detection, collection, and control of system leakage and means provided to detect leakage of activity from one system to another and preclude its release to the environment.94 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. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface
