DATE (15) ABSTRACT (Limit to 1400 spaces, i.e., approximately 15 single-spaced typewritten lines) (16) On March 7, 1996, it was identified that the requirements of Technical Specification 4.6.1.1 were not fully implemented at Units 1 and 2 . Specifically, the monthly surveillance procedure that has been used to implement Technical Specification 4.6.1.1 did not direct position verification of the Refueling Canal Supply and Discharge Containment Isolation Valves.' This condition has existed since at least 1986. The apparent cause of this occurrence is attributed to a lack of adequate controls for the development and maintenance of Technical Specification surveillance procedures.

This weakness was previously identified in LER 311/95-008.

Corrective actions as stated in this previous LER are still in progress, and will include verification of the adequacy of all Technical Specification surveillance procedures, with 1-imi ted exceptions, and verification that controls are in place to maint3in the adequacy of the procedures.

This event is reportable in accordance with 10 CFR 73(a) (2) (i) (B) I any condition prohibited by the plant's Technical Specifications.

-Pressurized Water Reactor Waste Disposal Liquid System (WL) IDENTIFICATION OF OCCURRENCE Discovery Date: March 7, 1996 LER NUMBER (6) YEAR I SEQUENTIAL I REVISION NUMBER NUMBER 9 6 00 PAGE (3) 2 OF 4 Event Dates: The failure to perform adequate, documented verification of the referenced containment isolation valves occurred during each required surveillance interval, possibly since initial licer.sing, with the plants in Modes 1 through 4. CONDITIONS PRIOR TO OCCURRENCE At the time of identification, Salem Uni ts 1 and 2 were shutdown and defueled.

The Technical Specification surveillance Mode applicability is 1 through 4. DESCRIPTION OF OCCURRENCE Technical Specification 4.6.1.1 states, "Primary CONTAINMENT INTEGRITY shall be demonstrated at least once per 31 days by verifying that all penetrations not capable of being closed by OPERABLE containment automatic isolation valves and required to be closed during accident conditions are closed by valves, blind flanges, or deactivated automatic valves secured in their positions, except as provided ip Table 3.6-1 of Specification 3.6.3.1, and all equipment hatches are closed and sealed." In response to questions raised during the NRC Restart Team Inspection at Hope Creek, Salem Station initiated a review of its procedure for containment isolation valve position verification.

The review identified four valves (1WL190, 1WL191, 2WL190, ana 2WL191) that were not included in the monthly (31 day) Containment Isolation Valves surveillance procedure.

A random sampling of historical records showed that the valves had been missing from the surveillance tests at both units since at least 1986. The valves have been listed in Table 3.6-1 of the Unit 1 and 2 Technical Specifications since the licenses were issued. NRC FORM 366A (4-95)

This weakness was previously identified in LER 311/95-008.

PRIOR SIMILAR OCCURRENCES A review of LERs for Salem Units 1 and 2 identified the following two LERs issued in the last two years relating to missed Technical Specification surveillances due to procedural deficiencies:

LER 272/94-008 "Quarterly Channel Functional Testing of Position Indication For Power Operated Relief Valves Missed On Both Units" identified an occurrence where a procedure was revised in response to Generic Letter 90-06 without a revision to Technical Specifications which resulted in missed surveillance testing of Power Operated Relief Valves while in Modes 1 and 2. LER 311/95-008 "Technical Specifications

4. 9. 9 Missed Isolation Testing" identified that the surveillance testing performed, prior to core alterations, for the Containment Purge and Pressure-Vacuum Relief isolation system did not confirm the manually initiated isolation function as required by Technical Specifications 4.9.9. SAFETY CONSEQUENCES AND IMPLICATIONS Administrative controls such as post outage valve lineup checks would likely have ensured that the valves were properly shut prior to power operations following an outage. Additionally, the monthly surveillance procedures did include position verification of the outside Containment Refueling Canal Supply and Discharge isolation valves (1SF22, 1SF36, 2SF22, and 2SF36). Thus there were no safety consequences associated with this condition since containment integrity would not have been affected in the unlikely event of an accident.

Based on the above, the heal th and safety of the public were not affected.
