reviewed for completeness. For pumps and valves the reviewer utilizes the information contained in the following documents in addition to the acceptance criteria cited under subsections II.1 and II.2 in order to evaluate the functional specifications selected for review: (1) NRC Regulatory Guide 1.148, "Functional Specification for Active Valve Assemblies in Systems Important to Safety in Nuclear Power Plants." (2) ANSI N278.1-1975, 'Self-Operated and Power-Operated Safety-Related Valves Functional Specification Standard" (endorsed by Regulatory Guide 1.148, as supplemental and modified). (3) ANSI/ASME N551.1, "Standard for Qualification of ASME Code Class 2 & 3 Pump Assemblies for Safety Systems Service, General Requirements" (DRAFT). (Although this draft standard has not been endorsed by the NRC, it will be used for guidance purposes.) It is important that the applicants program is complete in this area so that the staff may be assured that the proper system parameters are specified and appropriate loads defined. The review will screen several key components in the systems to establish the program objectives. e. The test procedures are reviewed against the criteria set forth in subsections II.1 or II.2. In evaluating an applicant's program for pumps and valves, the reviewer also utilizes, for guidance purposes, the information contained in the following documents, although these. draft documents have not been endorsed by the NRC: (1) ANSI 6.16.41, uFunctional Qualification Requirements for Power Operated Active Valve Assemblies for Nuclear Power Plants" (DRAFT) (2) ANSI N41.6, "Functional Qualification Requirements for Actuators for Power Operated Valve Assemblies for Nuclear Power Plants' (DRAFT) (3) ANSI/ASME N551.2, Standard for Qualification of ASME Code Class 2 & 3 Pumps for Safety Systems Service" (DRAFT) (4) ANSI N45 N551.4, 'Functional Qualification of Motor Drives for Safety Related Code Class 2 and 3 Pumps for Nuclear Power Plants" (DRAFT) 3.10-12 Rev.
