dual purpose or vibration arrestor type, an indication of whether both snubber and component were evaluated for fatigue strength, the evaluation is performed under SRP Section 3.9.3 Appendix A. D. The applicant should provide assurance that all snubbers are properly installed before preoperational piping vibration and plant startup tests. The applicant may use visual observation of piping systems and measurement of thermal movements during plant startup tests to verify that snubbers are operable (not locked up). The piping preoperational vibration and plant startup test programs should discuss the provisions for such examinations and measurements as described in SRP Section 3.9.2. E. The applicant should discuss accessibility provisions for maintenance, inservice inspection and testing, and possible repair or replacement of snubbers consistent with the provisions of the applicable NRC standard technical specifications. 5. Relief Requests and Proposed Alternatives A. The applicant should identify the component identified for which it requests relief: i. Name and number as given in SAR ii. Component functions iii. ASME Code, Section III, Code Class iv. Valve category as defined in Subsection ISTC-1300 of the OM Code v. Pump group as defined in Subsection ISTB-2000 of the OM Code 3.9.6-16 Revision 3 - March 2007 B. The applicant should identify the ASME OM Code requirement(s) from which it is requesting relief. C. The applicant should specify the basis under which it is requesting relief and then explain why complying with the OM Code is impractical. D. For alternatives to the OM Code requirements, the applicant should provide sufficient details to demonstrate that (1) the proposed alternative will provide an acceptable level of quality and safety, or (2) compliance with the specified requirement would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety. E. The applicant should specify a schedule for the
