4. Meeting the requirements of GDC 54 provides assurance that valves in such systems are capable of performing their intended safety function. 11. Appendix B to 10 CFR Part 50 requires that applicants establish and execute an acceptable quality assurance program, including design, testing, and records control. Meeting the requirements of Appendix B to 10 CFR Part 50 provides assurance that designs, tests, IST programs and documentation for pumps, valves, and dynamic restraints will comply with established standards and criteria, thereby ensuring that such equipment will be capable of performing its intended safety functions. 12. 10 CFR 50.55a(f) for pumps and valves, and 10 CFR 50.55a(g) for dynamic restraints, requires that such pumps, valves, and dynamic restraints whose function is required for safety (i.e, in code classes 1, 2, and 3) be assessed for their operational readiness in accordance with the applicable revision of the OM Code, as described therein. In 10 CFR 50.55a(b)(3), the regulations take exception to, or supplement, the OM Code provisions for these components. Meeting the requirements of 10 CFR 50.55a(f) and (g) and 10 CFR 50.55a(b)(3) provides assurance that such pumps, valves, and dynamic restraints are capable of performing their intended safety function. The following provides the applicable OM Codes for IST programs: a. Pumps and valves in facilities whose construction permit is issued on or after November 22, 1999 must be designed and provided with access to enable the performance of IST of the pumps and valves for assessing operational readiness as set forth in the editions and addenda of the OM Code incorporated by reference in 10 CFR 50.55a at the time the construction permit is issued. b. IST programs implemented during the initial 120-month interval must comply with the requirements in the latest edition and addenda of the OM Code incorporated by reference in 10 CFR 50.55a on the date 12 months before the date of issuance of the
