nical Rationale87 The technical rationale for application of these acceptance criteria to reviewing inservice testing of pumps and valves is discussed in the following paragraphs:88 1. Compliance with GDC 1 requires that components important to safety be tested to quality standards commensurate with the importance of the safety functions to be performed. The inservice testing of pumps and valves described in this SRP section provides for such testing according to the type and service category of the valve. The inservice DRAFT Rev. 3 - April 1996 3.9.6-16 testing requirements are based on sound engineering principles as well as service experience in nuclear plants. Meeting the requirements of GDC 1 provides assurance that pumps and valves important to safety are capable of performing their intended safety function.89 2. Compliance with GDC 37 requires that the emergency core cooling system be designed to permit appropriate periodic and functional testing to ensure the structural and leak tight integrity of its components as well as the operability and performance of the active components of the system. The acceptance criteria in SRP Section 3.9.6 cite inservice tests required by the ASME Code as well as other preoperational and inservice tests for pumps and valves to ensure their leak tight integrity as well as their operability and performance. This testing is specifically applicable to safety-related pumps and valves in the emergency core cooling system and is intended to meet the requirements of GDC 37. Meeting the requirements of GDC 37 provides assurance that pumps and valves important to safety are capable of performing their intended safety function.90 3. Compliance with GDC 40 requires that the containment heat removal system be designed to permit appropriate periodic and functional testing to ensure the structural and leak tight integrity of its components as well as the operability and performance of the active components of the system.
