ical code requirements may be granted by the Commission upon application by the applicant. Consideration of the burden on the applicant is a factor in the NRC's review and evaluation.79 b. Approval of Alternatives to the ASME Code Requirements80 Requests for relief fromAuthorization of alternatives to Section XIinservice 81 testing requirements will be granted by the staff if the applicant has adequately 82 demonstrated either of the following;: a.(1) Compliance with the code requirements would result in hardships or unusual difficulties without a compensating increase in the level of safety, and noncompliance will provide an acceptable level of quality and safety. b.(2) Proposed alternatives to the code requirements or portions thereof will provide an acceptable level of quality and safety. DRAFT Rev. 3 - April 1996 3.9.6-14 5. Pump, Valve, and Other Design or Qualification Provisions Related To Inservice Testing of Pumps and Valves83 The following guidance should be applied in review of new applications, based, in part, on staff positions stated in SECY 90-016 (Reference 13) and SECY 93-087 (Reference 14): a. Safety-related pump, valve, and piping designs should include provisions to allow full flow testing of pumps and check valves at maximum design flow.84 b. Prototypical testing of each size, type, and model of MOV and POV should be conducted, under a range of differential pressure and flow conditions up to the design conditions, to ensure the adequacy of the thrust and torque (if applicable) that the valve operator can deliver under design (design-basis and required operating) conditions. (1) The design conditions include fluid flow, differential pressure (including pipe break), system pressure, fluid temperature, ambient temperature, minimum voltage (if applicable), air supply (if applicable), minimum and maximum stroke time requirements (if applicable), and appropriate combinations. (2) The testing of each size, type, and model should include test data from
