Ref: LCR 81-25 PROPOSED CHANGE TECHNICAL SPECIFICATIONS SALEM GENERATING STATION UNIT NOS. 1 AND 2 DESCRIPTION OF CHANGE A new page, 3/4 6-8a, containing specifications on Containment Purge Supply and Exhaust isolation valves and the Containment Pressure-Vacuum Relief isolation*valves, should be added for Unit No 1 and the corresponding page in Unit No. 2 specifications 3/4 6-9 should be modified to ensure the Purge and Supply isola-tion valves are locked shut in Modes 1 thru 4. Additionally, a surveillance requirement for each unit should be added to provide valve seal testing on the above valves to identify possible degradation of the seals due to environmental and/or usage conditions over the life of the seals. Lastly, on Unit No. 1, a revision to TABLE 3.6-1, CONTAINMENT ISOLATION VALVES, should delete an asterisk/footnote which allows administratively controlled opening of lVCl, 2, .3, and 4.

REASON FOR CHANGE These changes are in response to NRC request to resolve generic concerns of purging and venting containments. Specifically, the changes address items in a November 6, 1981 letter from Mr. Varga of the NRC to Mr. F.W. Schneider, Vice President - Production.

SAFETY EVALUATION This change request involves .no-Unreviewed.Safefy-.Question. The valves which are locked shut in Modes 1 thru 4 by this change are presently administratively closed in those modes and the increase in surveillance on the valve seals is strictly a conservative measure which enhances the possibility of detecting valve seal problems before they reach a degree of leakage which would impose a .limit on plant operation.

BASIS FOR FEE CLASSIFICATION This change is deemed *.not to* involve a significant hazards consideration and is therefore a class III amendment for Unit No. 1 and a class I amendment for Unit No. 2.
