until the ICAS safety function is no longer required.20 d. Capability of the system (including interconnected systems designed to provide backup capability to the ICAS) to supply clean, dry, oil-free instrument air. 21 e. The provisions to allow periodic testing of the quality of the air delivered to the ICAS components.22 f. The provisions to allow periodic pressure, leakage, and functional testing of the safety-related portions of the ICAS.23 g. The provisions to ensure adequate inventory and quality for performance of ICAS functions when equipment is out of service for maintenance or repair.24 9.3.1-3 DRAFT Rev. 2 - April 1996 h. The potential for radiological contamination of the ICAS, and if applicable, reviews the means provided to detect leakage from radioactive systems to the ICAS and preclude releases to the environment.25 i. The air quality and overpressure protection from air or nitrogen accumulators, or nitrogen systems used for PWR primary and secondary system power operated relief valves (PORVs) and BWR safety relief valves (SRVs).26 j. The provisions to allow periodic pressure and leakage testing of the accumulators provided for PWR PORVs or BWR SRVs.27 Review Interfaces:28 5. ASBSPLB also performs the following reviews under the SRP sections indicated: 29 1. Review of the protection against external events is performed as follows: 5.aa. Review of flood protection is performed under SRP Section 3.4.1,. 5.cb. Review of the structures, systems, and components to be protected against externally generated missiles is performed under SRP Section 3.5.2., and A statement to the effect that the system is located in a seismic Category I structure that is tornado missile and flood protected, or that components of the system will be located in individual cubicles or rooms that will withstand the effects of tornado winds, flooding, and missiles is acceptable.30 5.b.2.
