ollowing to verify whether air-operated components function as intended during design-basis events, loss of offsite power, or station blackout: A. The ICAS functional design, including air or nitrogen accumulators, is in accordance with its intended function. B. Air-operated component failure positions are correct for assurance of required functions upon a sudden as well as a gradual loss of air pressure. C. Periodic testing leakage limits ensure air-operated component function as intended for required durations. For each case the design is acceptable if it meets minimum system requirements. 7. The reviewer verifies whether safety-related ICAS systems and components are not shared among nuclear power units unless such sharing is shown not to impair their ability to perform safety functions, including, in an accident in one unit, an orderly shutdown and cool-down of the remaining units. 8. The reviewer determines whether the CAS could become contaminated through interfaces with radioactive systems (e.g., contaminated due to leakage, valving errors, faulty operation in other radioactive systems, etc.). If the system could become contaminated, the reviewer ensures that provisions for detection, collection, and control of system leakage detect leakage of activity from one system to another and preclude its release to the environment. 9. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application,
