On 7/3/95, at 0735 hours0.00851 days <br />0.204 hours <br />0.00122 weeks <br />2.796675e-4 months <br />, the once per 31 days interval was missed for channel checking the 3 Seismic Monitoring Triaxial Time-History Accelograph Sensors and 4 Triaxial Peak Accelograph Sensors on Salem Unit 1. As such, Technical Specification (TS) SURVEILLANCE REQUIREMENT 4.3.3.3.1 was missed for the subject instruments, identified in TS Table 4.3-4. The involved surveillance was subsequently and I

satisfactorily completed approximately 6.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> late, on 7/3/95, at approximately 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br />. This occurrence is attributed to: personnel error - failure to adequately recognize/determine the necessity to perform the surveillance, failure to communicate the necessity to perform the procedure, and failure to take ownership to schedule the surveillance. Contributor: responsibilities for daily and outage scheduling were being streamlined/integrated for daily and outage scheduling, which allowed a lapse I

in identifying the subject surveillance. The appropriate levels of discipline (consistent with PSE&G personnel policies) were provided to involved personnel. The surveillance performance tracking report has been modified to enhance human factors.

The commitment for the required frequency of the review of this report has been clarified. The surveillance performance scheduling system has been changed to preclude a future similar occurrence. A position of "Surveillance Coordinator" in the Station Planning and Scheduling Group has been established for each Unit as an additional barrier to ensure continuity of sur~eillance scheduling and completion during plant at "power .and outage conditions .

As such, TS SURVEILLANCE REQUIREMENT 4.3.3.3.1 was not met for the subject instruments, which are identified in TS Table 4.3-4. The involved surveillance was subsequently and satisfactorily completed approximately six (6) and one half hours late, on July 3, 1995, at approximately 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br />. -

Analysis of Occurrence:

Operability of seismic monitoring Time-History Accelograph sensors and Triaxial Peak Accelograph sensors ensures the capability is available to compare a,measured seismic event to that established by the plant design basis. This occurrence involved an approximate six and one half hour lapse in the performance of the required periodic channel

LICENSEE EVENT REPORT (LER) TEXT CONTINUATION Salem Generating Station Docket Number LER Number Page 3 of 6 Unit# 1 50-272 95-013-00 Analysis of Occurrence: (cont'd) testing of this instrumentation. Discovery of this occurrence was made by the Maintenance - Controls Department TS Surveillance Coordinator (TSSC), approximately one half hour after the subject surveillance, "Seismic Strong Motion Instrumentation Channel Check", IC-13.2.003, went overdue.

Apparent Cause of Occurrence:

This occurrence is attributed to "Personnel Error", with contributors resulting from "Management/Quality Assurance Deficiency", both as classified in Appendix B of NUREG-1022.

Prior to July 3, 1995, the TSSC failed to adequately recognize or seek an understanding of the surveillance performance tracking report code information field.

Consequently, the TSSC was not aware of the necessity to perform the surveillance. Computer coding associated with the subject surveillance identified that performance of the surveillance is required in all operational modes.

Prior to this occurrence, on June 30, 1995, the Station TS Administrator recognized the necessity to advise the TSSC of the upcoming due date of the subject surveillance. However, he became distracted from performing this function and overlooked notifying the TSSC.

The Station Planning and Scheduling Group failed to adequately review the TS surveillance schedules and to ensure timely communication with the Maintenance Department of upcoming surveillances. Consequently, the surveillance was not included on the daily outage schedule for performance.

Management/Quality Assurance Contributors:

The TSSC failed to recognize or understand the meaning of applicable modes coding "7" on the surveillance report, which indicates (is applicable to) all plant operating modes. Prior to this occurrence, the requirements associated with the "7" mode coding had been conveyed via memorandum, dated May 22, 1992.

At the time of this occurrence, roles, responsibilities,

LICENSEE EVENT REPORT (LER) TEXT CONTINUATION Sale~ Generating Station Docket Number LER Number Page 4 of 6 Unit# 1 50-272 95-013-00 Cause of Occurrence: (cont'd)

Management/Quality Assurance Contributors: (cont'd) and positions of daily and outage scheduling of the Station Planning and Scheduling Group personnel were being streamlined and integrated into a uniform structure for daily and outage scheduling. This period of transition allowed a lapse in identifying the subject surveillance, which resulted in a lack of ownership for scheduling its completion. In addition, involved individuals in the Station Planning and Scheduling Group and the Maintenance - Controls Department, had been recently assigned to their positions.

Prior Similar Occurrences:

Prior similar occurrences of. late performances of TS surveillances have been reported in LERs 311/94-005-00, 311/88-011-00, 311/87-003-00, and 272/92-006-00. Corrective actions.to these prior occurrences have included: coaching and counseling of involved personnel, review of the events, stressing the importance of adequate communications, review of administrative procedure requirements, establishment of a Maintenance Controls Department TS Surveillance Coordinator sign-off log for daily review of reports listing upcoming overdue TS surveillances, and Management directive for a TS Administrator to inform TS surveillance coordinators of upcoming surveillances in a timely manner. While review shows these corrective actions were appropriate for these occurrences, the clear accountability for the schedule was not appropriately addressed. As such, the accountability for surveillance tracking has been enhanced through improvement in the Surveillance Performance Scheduling System.

Safety Significance:

This occurrence is reportable pursuant to 10CFRS0.73 (a) (2) (i) (B), due to failure to meet the requirements of the TS 4.3.3.3.1, Table 4.3-4. Although the subject surveillance was performed late, subsequent completion of this testing demonstrated continued operability of the instruments (required in all Operating Modes) during the period of time that completion of the testing was overdue.

LICENSEE EVENT REPORT (LER) TEXT CONTINUATION Salem Generating Station Docket Number LER Number Page 5 of 6 Unit# 1 50-272 95-013-00 Corrective Action:

The appropriate levels of discipline (consistent with PSE&G personnel policies) were provided to involved personnel.

The surveillance performance tracking report has been modified to enhance human factors, in order to provide a better understanding of coding information. This report will continue to be reviewed for potential overdue surveillances. However, PSE&G has modified this commitment (as described in LER 311/94-005-00) to clarify the required frequencies of this review.

Appropriate changes have been made to the surveillance performance scheduling system to preclude a future similar occurrence. These changes include identification of clear responsibilities for daily and outage scheduling. In addition, a position of "Surveillance Coordinator" has been established in the Station Planning and Scheduling Group (one coordinator per Salem Unit). These coordinators will serve as an additional barrier to ensure continuity of surveillance scheduling and completion during plant at power and outage conditions.
