Content:
Category 1 systems, components, equipment, and their supports (including supports for conduit and cable trays, and ventilation ducts). Compliance with the requirements of GDC 1 provides assurance that systems and components within the scope of this SRP section are capable of performing their intended safety functions. 2. GDC 2 requires that SSCs important to safety be designed to withstand the effects of expected natural phenomena combined with effects of normal and accident conditions without loss of capability to perform their safety functions. Vibration testing, dynamic analyses, and suitable comparisons are described in this SRP section for SSCs important to safety. The tests, analyses, and comparisons are in accordance with sound engineering practices and provide assurance that these SSCs are designed to withstand natural phenomena in combination with normal and accident conditions. Compliance with the requirements of GDC 2 provides assurance that SSCs within the scope of this SRP section are capable of performing their intended safety functions. 3. GDC 4 requires that the SSCs important to safety be designed to accommodate the effects of and be compatible with the environmental conditions of normal operation, maintenance, testing, and postulated accidents, including LOCAs. Staff positions on design of SSCs to withstand the dynamic effects of LOCAs in combination with other normal and design basis loads are described in SRP 3.9.2-31 Revision 4 – March 2017 Section 3.9.2. Testing to verify the ability of SSCs to withstand anticipated loads is also described. Compliance with the requirements of GDC 4 provides assurance that SSCs within the scope of this SRP section are capable of performing their intended safety functions. 4. GDC 14 requires that the RCPB be designed, fabricated, erected, and tested to have an extremely low probability of abnormal leakage, rapidly propagating failure, or gross rupture. Staff positions described in SRP Section 3.9.2 address
