SUPPLEMENTAL REPORT EXPECTED (14) EXPECTED MONTH DAY YEAR 'YES XINO SUBMISSION (If yes, complete EXPECTED SUBMISSION DATE). DATE(15) ABSTRACT (Limitto 1400 spaces, I.e., approximately 15 single-spaced typewritten lines) (16) On March 25 ,. 1996, the Technical Specification Surveillc..nce Improvement Project Team identified a potential Technical Specification violation regarding Channel Checks required by Technical Specification 4.3.2.1.1.

Items 1.f and 4.d of Table 4.3-2 require that Channel Checks be performed on the Steam Line Flow, Steam Line Pressure, and Reactor Coolant Average Temperature (Tavg) instrumentation at least once per shift in modes 1, 2 and 3. A further review determined that Tavg instruments are not Channel Checked as required by Specification 4.3.2.1.1.

A review of historical documentation indicates that both Salem Units 1 and 2 have not performed the Channel Check of Tavg instruments in modes 1, 2 and 3, potent-ially since initial plant startup. The cause of this occurrence is attributed to a lack of adequate controls for the development and maintenance of Technical Specifications surveillance procedures.

This weakness was previously identified in LER 311/95-008-00.

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

• Energy Industry Identification System (EIIS) codes and component function identifier codes appear in the text as (SS/CCC) CONDITIONS PRIOR TO OCCURRENCE i At the time of identification, Salem Units 1 and 2 were shutdown and defueled.

Technical Specification surveillance Mode applicability is 1, 2 and 3 for the Tavg Channel Check. DESCRIPTION OF OCCURRENCE As a Corrective Action from LER 311/95-006 a Technical Specification Surveillance Improvement Project (TSSIP) has been initiated.

Additional deficiencies found during the TSSIP will be documented in supplements to this LER. On March 25, 1996 during a review of the implementation of Technical Specification Surveillance Requirement 4.3.2.1.1, the TSSIP Team identified a potential Technical Specification violation regarding Channel Checks. Surveillance Requirement 4.3.2.1.1 requires a Channel Check on the instrument channels listed in Table 4.3-2. Items 1.f and 4.d of Table 4.3-2 list Engineered Safety Feature Actuations which occur on Steam Flow in Two Steam Lines--HIGH coincident with Tavg--LOW-LOW or Steam Line Pressure--LOW.

The Channel Check requirements apply such that a comparison of the Steam Line Flow {SB/-} indications is to be made once per shift in modes 1, 2 and 3, as are comparisons of the Tavg instruments, and the Steam Line Pressure instruments.

A further review determined that Channel Checks were being performed on the Steam Line Flow and Pressure instruments, but not on the Tavg instruments.

A review indicated the Channel Checks for Tavg have been required once per shift in Modes 1, 2 and 3 since the original issue of Technical Specifications for both Units 1 and 2. A historical review of the station operating log revisions since November 23, 1979 indicated that Channel Checks were not recorded for Tavg instruments in Modes 1, 2 and 3. CAUSE OF OCCURRENCE The 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.

NRC FORM 366A (4-95) U.S. NUCLEAR REGULATORY COMMISSION LICENSEE EVENT REPORT (LER) TEXT CONTINUATION FACILITY NAME (1) DOCKET NUMBER (2) LER NUMBER (6) 05000272 YEAR I SEQUENTIAL I REVISION NUMBER NUMBER SALEM GENERATING STATION, UNIT 1 96 -005 -00 TEXT (If more apace is required, use additional copies of NRC Form 366A) (17) PRIOR SIMILAR OCCURRENCES PAGE(3) 3 OF A review of LERs for Salem Units 1 and 2 identified three LERs in the last two years related to missed Technical Specification Surveillances due to a procedural deficiency:

3 LER 272/96-004 "Technical 4.6.1.1 Incomplete Containment Isolation Valve Position Verification Surveillance" identified an occurrence where Containment Isolation valves were omitted from monthly position verification surveillances due to inadequate implementation of Technical Specification surveillance requirements into procedures.

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 Specification

4.9.9 Missed

Isolation Initiation Testing," identified an occurrence where Containment Purge and Pressure-Vacuum Relief system isolation logic was not fully tested prior to and during Core Alterations due to inadequate implementation of Technical Specification surveillance requirements into procedures.

SAFETY CONSEQUENCES AND IMPLICATIONS There were no safety consequences for this occurrence since plant operators monitor Tavg readings for each loop every eight (8) hours in Modes 1 and 2, and every 30 minutes if the reactor is critical and Tavg is below 551 degrees F with the Tavg-Tref in alarm. In addition, the RC Loops Tavg Deviation alarm provides a continuous monitor of the deviation between all Tavg channels -alarming at a preset value. While not a Technical Specification required function, this alarm would readily alert operators to any significant deviation between Tavg indications.

The alarm response requires monitoring Tavg readings and initiating repairs to restore faulty instrumentation.

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

CORRECTIVE ACTIONS 1. Channel Checks of Tavg instruments will be incorporated into the operating logs for Modes 1 through 4 prior to each Unit restart. 2. A Technical Specification Surveillance Improvement Project (TSSIP) has been initiated for Salem Units 1 and 2. The scope and content of the TSSIP program was described previously in LER 311/95-008-00.

The TSSIP review is expected to be completed by December 31, 1997. NRC FORM 366A (4-95)
