port systems. The tabulation should include the following information: i. Identification of the systems and components in those systems that use dynamic restraints ii. The number of dynamic restraints used in each system and on components in that system iii. The type(s) of dynamic restraints (hydraulic or mechanical) and the corresponding supplier iv. Specification of whether the dynamic restraint was constructed in accordance with the ASME BPV Code, Section III, Subsection NF i. Statement on whether the dynamic restraint is used as a shock, vibration, or dual purpose dynamic restraint 3.9.6-29 Revision 4 – March 2017 ii. For dynamic restraints identified as either dual purpose or vibration arrestor type, an indication of whether both snubber and component were evaluated for fatigue strength; this evaluation is reviewed under SRP Section 3.9.3, Appendix A. D. The applicant should provide assurance that all dynamic restraints 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 dynamic restraints 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 dynamic restraints consistent with the provisions of the applicable NRC standard technical specifications. 6. Relief Requests and Proposed Alternatives A. Where an applicant requests relief from or an alternative to the provisions of the ASME OM Code, the applicant should identify the component identified for which it requests relief or a proposed alternative as follows: i. Name and number as given in FSAR ii. Component functions iii. ASME BPV Code, Section III,
