av OYSTER CREEK NUCLEAR GENERATING STATION Forked River, New Jersey 08731 Licensee Event Report Reportable Occurrence No. 50-219/82-08/03L Report Date March 19, 1982 Discovery Date February 10, 1982 Identification of Occurrence On February 10, 1982, it was identified that the monthly channel check of the back up accident monitoring system instrumentation requirad by Section 4.13. A.1 of the Technical Specif Leations was not be'ng performed r_s required.

This event is considered to be a reportable

'currence as defined in the Technical Specifications, paragraph 6.9.2.b.3.

Conditions Prior to Occurrence The plant'was in various operating modes during the time the condition existed.

Description of Occurrence On May 13, 1981, the official controlled copy of Amendment #54 to the Technical Specifications was received and included in Section 4.13.

This section requires a channel check of safety and relief valve primary and secondary position indications once every 31 days.

Since Amendment #54 was effective as of the date of issuance, May 8,1981, the surveillance was required by June 15, 1981.

Various delays prevented meeting the surveillance requirement as stated for the secondary valve position indicators. To this date, approximately eight channel check surveillances for the secondary accident monitoring thermocouples have not been performed. One channel check of the thermocouple indication was performed on July 13, 1981, and is recorded.

Since July 13, 1981, the Acoustic Monitoring System has been surveilled with a frequency as required by Technical Specifications. A Plant Operations Review Committee (PORC) action item was issuad to Plant Engineering on July 24, 1981, to revise the applicable surveillance procedure and the Master Surveillance Schedule. Plant Engineering prepared a revision to the daily tour sheet.

This procedure change was subsequently rejected by the PORC with a request to write a separate procedure and change the Master Surveillance Schedule.

Surveillance Procedure 602.4.011,

• Thermocouple Valve Monitoring System Channel Check, was approved by PORC on Janua ry 29, 1982.

The surveillance was completed March 12, 1982.

However, the Master Surveillance Schedule had not been updated.

.w Reportable Occurrence Page 2 Report No. 50-219/82-08/03L Apparent Cause of Occurrence The cause of the occurrence is attributed to the lack of proper administrative and procedural controls.

Analysis of Occurrence There are two systems used to indicate the open and closed position of the safety and relief valves. The primary system, which is the acoustic monitoring system, uses accelerometers to detect valve open or closed position.

The secondary system uses a thermocouple on the discharge side of each valve, and any flow past the valve seat would be indicated by a pronounced rise in temperature.

The safety significance is minimized by the fact that the acoustic monitoring system had been demonstrated to be operable during the entire period af missed thermocouple surveillances.

Corrective Action

A surveillance procedure, #602.4.011, Thermocouple Valve Monitoring System Channel Check, was approved by the PORC. The procedure is being incorporated into the Master Surveillance Schedule to insure the Technical Specification testing frequency requireme ts are met.

The Master Surveillance Schedule was reviewed to verify that all other surveillance requirements are included. The revised Master Surveillance Schedule will be issued by March 31, 1982.

All revisions to the operating license are now reviewed, upon receipt by the Licensing section of the Technical Functions Division, which will assign the appropriate department to update the Master Surveillance Schedule.
