, n 9 t OCONEE NUCLEAR STATION UNIT 1 CONFORMANCE WITH ASME SECTION XI, SUBSECTION IWV VALVE TESTING The inservice testing program for valves at Oconee Nuclear Station Unit 1 will be conducted in accordance with the methods described in Subsection IWV of Section XI of the ASME Boiler and Pressure Vessel Code where practicable, consistent with existing station design. The valve inservice testing program has been examined to determine which valves should be inspected and the extent of testing required for each valve. The following discussion describes the selection of valves to be tested:
- 1. Category A Valves These valves are those for which seal leakage is limited to a specific maximum amount in the closed position for fulfillment of their function.
In accordance with IWV-3410, exercise tests of Category A valves will be performed only on those valves which may be required to change position for the fulfillment of their function in an accident or for safe shutdown of the unit.
- 2. Category B Valves These are Class 1, 2 or.3 valves which may be required to change position for the fulfillment of their function in an accident or for safe shutdown of the unit but for which seat leakage is inconsequential.
- 3. Category C Valves Class 1, 2 and 3 check valves which must change position for fulfillment of their safety function will be exercise tested. The only relief valves for which testing is considered necessary are the pressurizer and main steam relief valves as all other relief valves serve no safety-related function.
- 4. Category D Valves There are no Category D valves at Oconee.
- 5. Category E Valves These valves shall be verified to be locked or sealed.
The attached is a listing of valves which are enecmpassed by the criteria listed above. Specific instances in which the code requirements are considered impractical are indicated.
