Public Service Electric and Gas Company Stanley LaBruna Public Service Electric and Gas Company P.O. Box 236, Hancocks Bridge, NJ 08038 609-339-4800 Vice President - Nuclear Operations December 21, 1989 NLR-N89240 United States Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 Gentlemen:
REVISION TO ATTACHMENT 1 OF RESPONSE TO NRC GENERIC LETTER NO. 89-04 SALEM GENERATING STATION UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 Public Service Electric and Gas Company (PSE&G) hereby submits a revision to Attachment 1 of response to Generic Letter 89-04 dated October 3, 1989 (ref: NLR-N89196).
Position 5 on page 2 of states "Any procedural revisions brought about by design value changes or by the addition/deletion of any valves will be incorporated by December 31, 1989 (which corresponds to the current test frequency)".
We request that the December 31, 1989 date be changed to read January 15, 1990.
All appropriate procedures have been revised; however, since they must be approved by the Station Operations Review Committee (SORC) it is felt that the January 15, 1990 dated is more appropriate.
Should you have any questions with regard to this submittal, we will be pleased to discuss them with you.

ATTACHMENT 1 NLR-N89240 Po1ition 4 - PRESSURE ISOLATION VALVE TESTilfi The pre11ur1 isolation valves (PtV's) at Salem Generating Station units are identified in each plant's Technical Specifications CTSl along with their maximum allowable leakaqe.
The IST Pro9ram was reviewed to ensure that all of these valves, and their associated allowable leakage values, are included in its scope.
Additionally, the test procedures for these valves were reviewed to aaaure that the valves were beinq individually tested as required.
P21itiog 5 - LIKITIHG VALUES or FULL-STROKE TIMES FOR PoliR OPERATED VALVES The Code intent. vith respect to measurinq the tull-stroke times of* power operated valves is to detect valve deqradation.
PSE&G's Salem Generating Station presently complies fully with ASHE Section XI, subsection IWV, reqardinq limitin9 stroke time values for power operated valves and required corrective actions.
Presently, if the stroke time increases by the code specified amount from the previous stroke time, the test frequency is increased to once per month (if the testin9 in that operating mode is possible) until corrective action can be ta~en.
At Salem Station, the 4.0.5(V) -,lintenance Procedure controls the monthly testing requirements and issuance of work requests tor corrective actions.
Because, as the Generic Letter states, "The code does not provide any requirements or guidelines for establishinq these limits nor does it identify the relationship ttlat should e.'<1St between these limits and any limits identified for the relevant valves in the plant TS or safety analysis, we have reviewed the licensin9 and/or desiqn bases for each power operated valve in our program and taken the followin9 position:
- 1)
All valves have been reviewed and provided with a "desiqn basis or
- 11censin9 value 11 for declaring valve operability (sources are Technical Specifications, CFSAR, Manufacturer. NSSS Vendor. etc.).
- 2)
The standard code requirements of IWV-3413(a) and IWV-3417(b) will continue to be followed by comparinq previous valve stroke times w1th present stroke time and taking the appropriate actions.
Jl PSE&G continue* to follov industry efforts and is presen~ly reviewinq our 4.0.5 (V) Proqram1 for chanqes that will enhance our trending capabilities tor power operated valves.
In summary, for each power operated valve in our pro~ram, a '
1desi9a value" tor determininq operability haa been established and if that value is exceeded that valve or its associated system will be declared inoperable in accordance ~itl1 the Technical Specifications. Any procedural revisions brouqht about by desiqn value chanqes. or by the addition/deletion ot any valves will be incorporate~ by t Janu~ry 15, l990~..,/ (which corruponds to the current test trequency).
Baaed upon their review of our current 4.0.S (V) Proqram techni~ues, an IST task team (comprised of a Central Preventative Maintenance Group and Technical Department personnel from each station) vill detail improvements in IST testing, trending and tracking by March* Jl, 1990.
The1e improvements will be implemented in accordance with existin9 Reliability Centered Maintenance methodology.
