development of IST programs for POVs that incorporate the lessons learned from MOV analysis and tests in response to GL 89-10, “Safety- Related Motor-Operated Valve Testing and Surveillance.” With respect to AOVs, the following attributes meet the intent of RIS 2000-03: (a) Setpoints for AOVs will be defined based on current vendor information or valve qualification testing, such that the valve is capable of performing its design-basis functions. (b) Periodic static testing will be performed to identify potential degradation, unless those valves are periodically cycled during normal plant operation under conditions that meet or exceed the worst case operating conditions within the licensing basis of the plant for the valve, which would provide adequate periodic demonstration of AOV capability. If necessary based on valve qualification or operating experience, periodic dynamic testing will be performed to re-verify the capability of the valve to perform its safety functions. (c) Sufficient testing will be used to collect relevant data (e.g., valve stem thrust and torque, fluid pressure and temperature, stroke time, operating and/or control air pressure, etc.) to verify the valve meets the functional requirements of the qualification specification. (d) Test frequency will be specified and evaluated each refueling outage based on data trends as a result of testing. Frequency for periodic testing will be in accordance with the JOG AOV Program Document and the NRC staff comments on this program in an NRC staff letter dated October 8, 1999, from Eugene V. Imbro. (e) Safety-related AOVs are assigned the highest category according to the JOG AOV program. (f) Post-maintenance procedures will include appropriate instructions and criteria to demonstrate baseline testing is re-performed as necessary when maintenance on a valve, valve repair, or replacement has the potential to affect valve functional performance. 3.9.6-22 Revision 4 – March 2017 (g) Guidance is included
