, §50.55a(g)Subsection 50.55a(f) of 10 CFR, as it relates to including 37 pumps and valves whose function is required for safety in the Inservice Inspection Program to verify operational readiness by periodic testing. Specific criteria necessary to meet the relevant requirements of the Commission regulations identified above are as follows:provided in the following subsections. Additional guidance 38 regarding the historical and current perspectives on the regulatory requirements for inservice testing programs for pumps and valves is provided in NUREG-1482, which includes information on the suggested format and content for inservice testing programs and relief requests, examples of relief requests, clarification of issues described in NRC communications on inservice testing, and information regarding current staff positions on inservice testing. Applicants should use NUREG-1482 as guidance for developing inservice testing programs. 39 ASME Code cases that refer to inservice testing of pumps and valves are acceptable as endorsed in Regulatory Guide 1.147.40 1. Inservice Testing of Pumps a. The scope of the applicant's test program is acceptable if it is in agreement with IWP-1000 of Section XI of the Code includes all of the ASME Code Class 1, 2, and 3 (or equivalent for older plants) pumps described in 10 CFR 50.55a(f), Section 1 of OM 6, and, in addition, may includes pumps not categorized as 41 42 Code Class 1, 2, or 3, but which are considered to be safety-related (see Position 43 11 of Generic Letter 89-04, Attachment 1 (Reference 12)) . Since the pump test 44 program is based on the detection of changes in the hydraulic and mechanical condition of a pump relative to a reference test specified in IWP-3000, the establishment of a reference set of parametersset of reference values, as described in Section 2, and paragraphs 4.3 and 5.2 of OM 6, and a consistent test method 45 is aare basic criteriaon of the program. 46 b. The pump test program is acceptable if it
