REVIEW RESPONSIBILITIES Primary - Materials Engineering Branch (MTEB) Secondary - Chemical Engineering Branch (CMEB) I. AREAS OF REVIEW Engineered safety features (ESF) are provided in nuclear plants to mitigate the consequenes of design basis or loss-of-coolant accidents, even though the occur- rence of tlese accidents is very unlikely. The General Design Criteria (GDC) 1, 4, 14, 31, 35, 41 and Appendix B of 10 CFR Part 50, and 10 CFR Part 50, §50.55a require that certain systems be provided to serve as Engineered safety features (ESF). To meet GDC 14 the fluids used in ESF systems when interacting with the reactor coolant pressure boundary should have a low probability of causing abnormal leakage, rapidly propagating failure and of gross rupture. Containment systems, residual heat removal system, emergency core cooling systems, containment heat removal systems, containment atmosphere cleanup systems, and certain cooling water systems are typical of the systems that are required to be provided as ESF. The materials and fluids compatibility for these systems are reviewed in this Standard Review Plan (SRP) section. The General Design Criteria (GDC) establish functional requirements for specific systems. Specific acceptance criteria identified in subsection II of this SRP section establish the basis for acceptance of materials and fluids compatibility of the ESF systems. The emergency core cooling system, the containment heat removal system, the con- tainment cleanup systems and other ESF systems are described in Section 6 of the SAR and are reviewed in accordance with the SRP sections for the individual sys- tems. The fluids compatibility and materials for these systems are reviewed in this SRP section. The fluid and material compatibility for the auxiliary systems that directly sup- port the ESF systems identified above, include systems such as the CCW, SW, ESF ventilation. These systems are reviewed in this SRP section upon request of the respective primary
