The PSB reviews reactor auxiliary cooling water systems (CWS) that are required for safe shutdown during normal, operational transient, and accident conditions and for mitigating the consequences of an accident or preventing the occurrence of an accident. These include closed loop auxiliary cooling water systems for reactor system components, reactor shutdown equipment, ventilation equipment, and components of the emergency core cooling system (ECCS). The review of these systems includes components of the system, valves and piping, and points of connection or interfaces with other systems. Emphasis is placed on the CWS for safety-related components such as LCCS equipment, ventilation equipment, and reactor shutdown equipment. The PSB reviews reactor auxiliary cooling water systems to ensure conformance with the requirements of General Design Criteria 2, 4, 5, 44, 45, and 46. 1. The PS8 reviews the capability of the auxiliary cooling systems to provide adequate cooling water to safety-related ECCS components and reactor auxi-liary equipment for all planned operating conditions. The review includes the following points: a. The functional performance requirements of the system including the ability to withstand adverse operational (i.e., water hammer) and environmental occurrences, operability requirements for normal operation, and requirements for operation during and subsequent to postulated accidents
