ASME CODE CASE N-508 SALEM AND HOPE CREEK GENERATING STATIONS DOCKET NOS. 50-272, 50-311 AND 50-354 Public Service Electric and Gas Company (PSE&G) requests approval, per 10CFR.50.55a, Section (a) (3) and footnote 6, to use ASME Code Case N-508 (copy attached) for Salem and Hope Creek Generating Stations. This ASME Section XI Code Case entitled,"Rotation of Serviced Snubbers and Pressure Relief Valves for the Purposes of Testing," was approved by ASME and published on March 11, 1993. The use of this Code Case is not presently referenced in NRC Regulatory Guide 1.147,"Inservice Inspection Code Case Acceptability," Revision 10, dated July 1993.
Code Case N-508 provides an alternative to the current Section XI, Paragraph IWA-7000 requirements to generate a replacement plan when removing snubbers or pressure relief valves for testing. PSE&G's Code Job Package (CJP) is the equivalent of the Section XI replacement plan. As an alternative to this replacement plan (i.e., PSE&G CJP), nine requirements must be met
{Code Case items (a) thru (i)). PSE&G intends to meet all of these requirements.
Code Case item (f) requires a separate mechanism for tracking snubbers and pressure relief valves, which ensures traceability of Inservice Inspection {ISI) and testing records. PSE&G's ISI group utilizes a computer data base program to track the current test results of all snubbers by type, rating and serial number. I' This data base provides specifics identifying a snubbers physical plant location at any point in time. This program has been used by PSE&G for several years and is far more efficient than a CJP for providing test result traceability. A similar independent tracking mechanism will be used by the InserVice Testing (IST) group for relief valves prior to application of Code Case N-508.
These mechanisms will satisfy item (f) of Code Case N-508.

~UL211994 NLR-N94064 Each PSE&G CJP requires a significant effort by several PSE&G organizations (Maintenance, Technical, ISI and QA). Generating a separate CJP for each snubber or relief valve removed for testing does not provide improved quality or safety. Code Case N-508, through the elimination of the added work necessary to prepare CJPs, would substantially reduce the resources expended by various station groups, particularly during outages when the requisite testing and possibility of expanded testing exists.
This Code Case does not create any technical or administrative changes that would impact the existing Salem or Hope Creek: ISI Programs, IST Programs, or Technical Specifications. Also, it does not introduce a condition that would compromise existing levels of quality or safety.
PSE&G considers this submittal a Cost Beneficial Licensing Action (CBLA). We have estimated the cost savings as $4k/yr at each
- Salem Unit and $22k/yr at Hope Creek. Savings over the life of the plants is $88k Salem Unit 1, $104k Salem Unit 2 and $704k Hope Creek.
