e l g: SALEM UNIT 2 - IST INSPECTION INTERVAL FINAL RELIEF REQUEST - # 2 COMPONENT DESCRIPTIOl{:

Pressure Retaining Valves ASME CODE CL&SE:

ASME Section XI, Class 1 Valves ASME EXAMINATION REOUIREMENTS:

Relief is being requested from the visual (VT) examination requirements of Table IWB-2500 Examination Category B-M-2 Item No.

B6.7.

BASIS FOR RELIEF:

The disassembly of functional valves during the first ten year inspection interval for the sole purpose of performing a visual examination of the internals would have increased the likelihood-for component failure in the future and was contrary to good maintenance practices. Considering the uncertainy of the benefit involved with this examination, it is difficult to justify the additional radiation exposure that would be incurred as a result of the disassembly, examination and reassembly these valves. For example, estimates from radiation surveys performed on and around valve 2RH1 indicate that the total job dose that would be received in disassembling, examining and reassembling this valve be in excess of 4 man-rem. Public Service Electric & Gas feels implementation of this examinaticn is impractical for valves not scheduled for disassembly because of preventive or corrective maintenance. In later editions of Section XI, this examination is only required to be performed on valves scheduled for disassembly for maintenance purposes.

ALTERNATIVE EXAMINATION:

Public Service Electric and Gas examined at least one valve in a valve ,

group (valves of similar design and function) where at least one valve in the-group was disassembled for maintenance purposes during the inspection interval. If any valve examined was found to require corrective action, additional valves in that group would be disassembled and inspected as required by Section XI. ,

Utilizing the above guidelines, the following valves listed by group were never disassembled during the first inspection interval and therefore, the internals were not visually examined. A similar relief request has been submitted for the second ten year interval per later editions of the Code.
