Content:
containment heat removal systems allow for 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 the inspection of containment heat removal systems, indicating that provisions should be made for periodic inspection of system components. Meeting the requirements of GDC 39 with regard to periodic inspection of containment heat removal systems 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. 3. Compliance with GDC 40 requires that the design of containment heat removal systems permits periodic pressure and functional testing to ensure leaktight integrity, operability, and performance of active components, as well as overall system operability. This SRP section describes staff positions related to the testing of containment heat removal systems, indicating that provisions should be made for startup and periodic operability testing of these systems and their components. Meeting the requirements of GDC 40 with regard to testing of containment heat removal systems provides assurance that containment pressure and temperature are reduced to and maintained at acceptably low levels after any LOCA, thereby protecting the safety function of the containment as an engineered safety feature. 4. Compliance with 10 CFR 50.46(b)(5) requires that systems be provided to ensure long-term cooling after any initial operation of the ECCS. The system safety function is to maintain the core temperature at acceptably low levels after any LOCA. This SRP section describes staff positions and is intended to ensure that systems are provided to maintain adequate core cooling. Meeting the requirements of 10 CFR 50.46(b)(5) with regard to long-term cooling
