inspection and operability testing of the systems and system components such as pumps, valves, duct pressure- relieving devices, and spray nozzles. 8. To satisfy the system design requirements of GDC 38, instrumentation should be provided to monitor containment heat removal system and system component performance under normal and accident conditions. The instrumentation should be capable of determining whether a system is performing its intended function, or a system train or component is malfunctioning and should be isolated. Technical Rationale The technical rationale for application of these acceptance criteria to reviewing the containment heat removal systems is discussed in the following paragraphs:43 (a) Compliance with GDC 38 requires that systems be provided to remove heat from the reactor containment. The system safety function is to reduce containment pressure and temperature rapidly after any LOCA and to maintain them at acceptably low levels. This SRP section describes staff positions related to the design of containment heat removal systems. Requirements related to spray systems, heat removal systems, cooling water sources, and cooling water recirculation are discussed. Regulatory Guide 1.82 provides guidance for "Water Sources For Long-Term Recirculation Cooling Following a Loss-of-Coolant Accident." Meeting the requirements of GDC 38 regarding the characteristics of containment heat removal systems and their design provides assurance that containment pressure and temperature will be reduced to and maintained at acceptably low levels after any LOCA, thereby protecting the safety function of the containment as an engineered safety feature. 44 (b) Compliance with GDC 39 requires that containment heat removal systems be designed to permit appropriate periodic inspection of important components such as the torus, sumps, spray nozzles, and piping to ensure the integrity and capability of these systems. This SRP section describes staff positions related to
