f safety valves and relief valves. These ASME Code sections will be referred to as "OM 6," "OM 10," and "OM 1," respectively, in this SRP section. See Reference 8. DRAFT Rev. 3 - April 1996 3.9.6-2 is required for safety, and in addition includes pumps not categorized as Code 11 Class 1, 2, or 3 but which are considered to be safety related. b. Procedures for testing for speed, fluid pressure, flow rate, vibration amplitude, 12 lubricant level or pressure, and bearing temperature at normal pump operating conditions are reviewed. c. The pump test schedule is reviewed. d. The methods described in the SAR for measuring the reference values and inservice values for the pump parameters above are reviewed. 2. Inservice Testing of Valves The descriptive information in the SAR covering the inservice test program is reviewed for those ASME Code Class 1, 2 and 3 valves whose function is required for safety. 13 14 This review does not include those nonsafety-related valves exempted by the Code. 15 16 3. Relief Requests 10 CFR Part 50, §50.55a(g)Subsection 50.55a(f)(4) of 10 CFR requires a nuclear power 17 facility to periodically update its inservice testing program to meet the requirements of future revisions of Section XI of the ASME Code, as specified in 10 CFR 50.55a at 1 18 the time the inservice testing program is revised. However, if it proves impractical to 19 implement these criteria, the applicant is allowed to submit requests for relief from Section XIthe ASME Code requirements on a case-by-case basis. Accordingly, any 20 requests for relief are reviewed by the staff to determine if the proposed exceptions to Section XI will degrade the overall plant safety. Due consideration is given to the 21 burden upon the applicant that could result if the updated inservice testing criteria of Section XI were imposed on the facility. 22 4. Design and Qualification Provisions to Accommodate Inservice Testing General system and component designs and equipment qualification
