leakage, and functional testing is necessary to assure operational readiness. In addition, the staff will review the applicant’s plans for Service Life Monitoring of dynamic restraints. The dynamic restraints can be mechanical or hydraulic. C. The staff will review the applicant’s plans for establishing the duration (frequency) of IST program activities for dynamic restraints. D. The staff will review the applicant’s functional testing criteria or parameters for dynamic restraints. E. The staff will use SRP Section 3.9.3 for additional guidance on the design and testing of dynamic restraints. 6. Relief Requests and Alternative Authorizations to ASME Codes A. Pursuant to 10 CFR 50.55a(z), the Commission may authorize alternatives to ASME Code requirements if the alternatives will provide an acceptable level of quality and safety, or compliance will result in hardship or unusual difficulty without a compensating increase in the level of quality and safety. An applicant or licensee may submit a request for use of an alternative to specific ASME Code provisions for review by the NRC staff. The NRC provides guidance for the submittal of requests for alternatives to the ASME Code in NUREG-1482 (Revision 2). B. The ASME BPV Code and OM Code provide for alternatives to specific Code provisions for the code user in Code Cases. The NRC staff identifies acceptable code cases in RG 1.147, “Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1,” and RG 1.192, “Operation and Maintenance Code Case Acceptability, ASME OM Code,” with appropriate conditions, as incorporated by reference in 10 CFR 50.55a. C. Pursuant to 10 CFR 50.55a(f)(6)(i) for pumps and valves, and 10 CFR 50.55a(g)(6)(i) for dynamic restraints, the Commission may grant relief from the ASME OM Code requirements or ASME BPV Code, Section XI requirements, if conformance would be impractical for the facility (10 CFR 50.55a(f)(5)(iii) or 10 CFR 50.55a(g)(5)(iii), as applicable) and may
