REVIEW RESPONSIBILITIES Primary - Organization responsible for review of component integrity issues related to engineered safety features Secondary - None I. AREAS OF REVIEW Engineered safety features (ESF) are provided in nuclear plants to mitigate the consequences of design-basis or loss-of-coolant accidents, even though the occurrence of these accidents is very unlikely. The Commission regulations of 10 CFR Part 50 require that certain systems be provided to serve as ESF systems. The fluids used in ESF systems, when interacting with the reactor coolant pressure boundary (RCPB), should have a low probability of causing abnormal leakage, of rapidly propagating failure, and of gross rupture. Containment systems, residual heat removal systems, 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. 6.1.1-2 Revision 2 - March 2007 The emergency core cooling system, the containment heat removal system, the containment cleanup systems, and other ESF systems are described in the safety analysis report (SAR) and are reviewed in accordance with the SRP sections for the individual systems. The fluids compatibility and materials for these systems are reviewed in this SRP section. Auxiliary systems that directly support the ESF systems include systems such as the component cooling water (CCW), station service water (SSW), and ESF ventilation. The fluid and material compatibility of these systems are reviewed in this SRP section upon request of the responsible
