ABSTRACT (Limit to 1400 spaces, i.e., approximately 15 single-spaced typewritten lines) (16)

At 2058 hours0.0238 days <br />0.572 hours <br />0.0034 weeks <br />7.83069e-4 months <br /> on 2/24/95, a dedicated 3rd Nuclear Control Operator (NCO) placed control of pressurizer power relief valve 1PR2 in manual to support removal/inspection and channel calibration of a pressurizer pressure controller. Effective.the same time, 1PR2 was declared inoperable, in accordance with Technical Specifications (TSs)

• Subsequently, at 2158 hours0.025 days <br />0.599 hours <br />0.00357 weeks <br />8.21119e-4 months <br /> (same day) the Operations shift did not close the associated block valve, 1PR7, and the 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> timeframe of the TS required action was not met. Event discovery was made at 1910 hours0.0221 days <br />0.531 hours <br />0.00316 weeks <br />7.26755e-4 months <br /> on 2/25/95, by the offgoing Operations crew. Immediately following discovery, 1PR7 was closed to terminate the event. The event is attributed to personnel error (inattention to detail) by the involved Operations shift. Contributors: after selecting 1PR2 to manual control the 3rd NCO delayed closing 1PR7; the desk NCO and 3rd NCO became engaged with other work; and open 1PR7 was not recognized during the following shift turnover. Positive discipline has been taken regarding this event.

The Operations Engineer met.with the involved personnel and stressed the need for attention to detail and Management expectations regarding station operation and TS compliance. Nuclear Shift Supervisors have reviewed this event and-lessons learned with their respective shifts.

This event will be covered in licensed operator requalification training.  !

Westinghouse - Pressurized Water Reactor Energy Industry Identification System (EIIS) codes appear in the text as {xx}

Identification of Occurrence:

Failure to Restore Automatic Control Of Pressurizer Power Operated Relief Valve (PORV) 1PR2 Or Close Associated Block Valve 1PR7 Within One Hour Event Date: February 24, 1995 Report Date: March 27, 1995 This report was initiated by Incident Report No.95-173 Conditions Prior to Occurrence:

Mode 3 Reactor Power  % Unit Load MWe 1*'**

Heatup to normal operating temperature and pressure was in progress. To assist the Unit console Nuclear Control I.

- Operator (NCO) and the desk NCO, a dedicated third NCO was controlling pressurizer pressure, in manual.

Description of Occurrence:

At 2058 hours0.0238 days <br />0.572 hours <br />0.0034 weeks <br />7.83069e-4 months <br /> on February 24, 1995, the third NCO placed control of PORV 1PR2 in manual to support removal/inspection and channel calibration of pressurizer pressure controller 1PC-455K, in accordance with procedure Sl.IC-CC.RC-0082(Q).

Effective the same time, the valve was declared inoperable, in accordance with Technical Specification (TS) 3.4.3, ACTION: a. Subsequently, at 2158 hours0.025 days <br />0.599 hours <br />0.00357 weeks <br />8.21119e-4 months <br /> (same day) the Operations shift did not close the associated block valve, 1PR7, and therefore the one hour timeframe of the TS required action was not met. Discovery of this occurrence was made at 1910 hours0.0221 days <br />0.531 hours <br />0.00316 weeks <br />7.26755e-4 months <br /> on February 25, 1995, by the offgoing Operations crew, during shift turnover.

Immediately following event discovery, 1PR7 was then closed, which terminated the occurrence.

Unit # 1

• 50-272 LER Number 95-002-00 LICENSEE EVENT REPORT (LER) TEXT CONTINUATION Salem Generating Station Docket Number Page 3 of 4 Analysis of Occurrence:

In MODE 3 (HOT STANDBY), TS 3.4.3, ACTION: a., requires that with one PORV inoperable and capable of being manually cycled, within one hour either restore the PORV to OPERABLE status or close the associated block valve, with power maintained to the block valve; otherwise, be in HOT SHUTDOWN within the following six hours An operable PORV was administratively rendered ~noperable by placing it in manual control. Subsequently, the TS action time frame to close the associated block valve was not met and the occurrence was not discovered until approximately 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and 12 minutes later.

Apparent Cause of Occurrence:

This occurrence is attributed to "Personnel Error", as classified in NUREG-1022, Appendix B due to inattention to detail by the involved Operations shift crew. When the third NCO selected control of 1PR2 to manual he announced this action to the desk NCO, who logged that the TS action had been entered. However, within the immediate timeframe of placing control of the PORV to manual, the third NCO delayed closing 1PR7. In addition, both NCOs then became engaged with other work in progress and consequently overlooked the required closing of the block valve.

Subsequently, the open 1PR7 was not recognized by the involved NCOs and Nuclear Shift Supervisors (NSSs) during the following Operations shift turnover.

Prior Similar Occurrence:

Review of documentation shows this event is an isolated occurrence. In this event, the TS action statement was appropriately entered; however the required action was not completed within the one hour time frame, as the result of personnel error.

LER 311/94-006-00 reported a Unit 2 occurrence on March 3, 1994, where documented entry into ACTION: ,a of corresponding Unit 2 TS 3.4.5 was not performed following closure of the PORV block valves. In the 1994 occurrence, the TS action statement was not entered due to an interpretive misunderstanding of the action statement.

'f Unit # 1 LICENSEE EVENT REPORT (LER) TEXT CONTINUATION Salem Generating Station Docket Number 50-272 LER Number 95-002-00 Page 4 of 4 Prior Similar Occurrence: (cont'd)

Corrective action to the 1994 occurrence included appropriate TS revision.

Safety Significance:

This occurrence is reportable pursuant to 10CFR50.73(a) (2) (i) (B) due to failure to comply with TS.

This occurrence had minimal safety significance as credit is not taken for PORV operation in the accident analyses of the Salem Updated Final Safety Analysis Report. In addition, during this occurrence the PORV remained functionally operable and capable of being opened, if required.

Corrective Action:

Positive discipline has been taken regarding the personnel error.

As a result of this occurrence, the Operations Engineer met with the involved Operations shift personnel and stressed the need for attention to detail and Management expectations regarding operation of the station and TS compliance.

Senior Nuclear Shift Supervisors have reviewed the circumstances of this occurrence and lessons learned with their respective shifts.

In addition, this occurrence will be covered in licensed operator requalification training.
