No immediate corrective action was necessary since all data was current at time of the discovery.

The root cause is less than adequate personnel work practices. Personnel involved were subjected to disciplinary measures. Management expectations regarding conduct of tours and accuracy of records and data have been communicated to station personnel.

Further investigations into other departmental logs is ongoing and will be reported in a Supplemental LER.

This event had no significance to the health and safety of-the public. The Supply System believes it has high significance with respect to the Supply System's mission and the public trust and confidence.

HISSED TECHNICAL SPECIFICATION SURVEILLANCE AND FIRE TOUR DATA DUE TO LESS THAN ADEQUATE WORK PRACTICES n

Power Level - 0%

Plant Mode - Reactor defueled v n On May 19, 1992 a Management Review Team concluded that a surveillance data point required by Technical Specifications had not been properly verified by a non-licensed Equipment Operator and, hence, constituted a missed surveillance. The data point was the Area Temperature Monitoring surveillance for the Division I Emergency Diesel Generator.

Management had initiated reviews of Plant Equipment Operator (EO) Log data, which revealed a discrepancy for the area temperature data taken on February 28, 1992. The EO Log entries were compared against security computer records. The comparison revealed that entry into the Diesel Generator Room, within the time frame allowed for the surveillance, could not be verified by security logs. Entry into the area is necessary since the temperature indicator must be locally read.

Similar discrepancies between recorded data and operator location were found in Fire Tour Log information. Fire Tours are also part of EO duties.

Imm i rr iv A on Since the missing data was sporadic and historical, no immediate corrective action was necessary. Area temperature surveillances and fire tours were current at the time reportability was determined.

hr I i n rr iv in Further Evaluation The investigation was undertaken, at Management initiative, in order to reaffirm that log

'eeping problems experienced at other utilities were not present at WNP 2. However management expectations were not verified since discrepant information was discovered in the log records of twenty Equipment Operators. Nineteen other EOs had no instance of log information which disagreed with security records.

Of the twenty EOs, three had between 20 and 40 unexplained discrepancies, seven had 4 to 8 discrepancies and 10 had two or fewer.

HISSED TECHNICAL SPECIFICATION SURVEILLANCE AND FIRE TOUR DATA DUE TO LESS THAN ADEQUATE WORK PRACTICES

2. Of the over three months of fire tour logs reviewed,128 inspections were missed. The investigation revealed that six operator tour data points were also missed. One missed operator tour data point resulted in a violation of the Area Temperature Monitoring Technical Specification (3/4.7.8). This condition is reportable under 10 CFR 50.73(a)(2)(i)(B), a

=

condition prohibited by Technical Specifications.

The missed fire tour data constituted a violation of Technical Specification 6.8.1.g, which requires that a Fire Protection Program be established, implemented and maintained. The investigation results indicate inadequate implementation of this program, which is also reportable under 10 CFR 50.73(a)(2)(i)(B), a condition prohibited by Technical Specifications.

3. The Supply System had been in contact with NRC Regional Management and the local NRC Resident Inspectors throughout the investigation. On May 19, 1992, Plant Management formally notified the NRC that the Supply System considered the combined inspection results to be a violation of 10CFR 50.9, which requires that information provided to the NRC be complete and accurate in all material respects. As outlined in the Statements of Consideration for this rule, the standard for what constitutes "material" information is one of a licensee's own recognition of information with significant public health or safety or common defense or security implications.

Approximately half of the Equipment Operators had discrepant log entries. Although the proportion of missed data points is small, the relatively large percentage of individuals with performance errors is considered a challenge to the credibility of station records. The Supply System believes that WNP-2 records and reputation must be without blemish.

error or pervasive inaccuracy in these records is considered by the Supply System Any'ignificant to be significant.

4. The root cause for these events is less than adequate Personnel Work Practices. Required verifications were not performed in that personnel performing the tours did not personally verify each data point. A minor contributing cause is Management Method - Policy not Adequately Disseminated. Some of the EO's expressed belief that it was not necessary to personally verify each point but that there were acceptable equivalent methods (e.g someone exiting the room attesting to acceptable conditions in the room).

MISSED TECHNICAL SPECIFICATION SURVEILLANCE AND FIRE TOUR DATA DUE TO LESS THAN ADEQUATE WORK PRACTICES Further Corrective Action All EOs with unexplained differences between tour log and security log data received disciplinary action. These actions ranged from unpaid suspension from assigned duties to formal reprimand. Specific individual action was related directly to the number of discrepancies found with the individual's logs.

2. Management expectations regarding the veracity of information were communicated to Operations Directorate personnel via memo on May 18, 1992.

3. Plant Management expectations regarding the conduct of tours were communicated, via memorandum, to personnel with plant access. This was completed on April 27, 1992.

r

4. Similar audits of other selected departmental logs will be completed by July 15, 1992. The results of this audit will be communicated to the NRC by August 15, 1992.

A periodic surveillance is being developed to assess the log keeping performance of various departments. This surveillance will be first implemented by September 30, 1992.

f i nifi These missed data points presented no significant physical challenge to the operability of plant equipment.

The area temperature in the Diesel Generator 1 Room, as measured the shift before and after, was within acceptable limits. The external ambient temperature for the day ranged from 43'F to 48'F, with an average wind speed of 2.6 mph. It is most unlikely that the room temperature could have significantly changed in the twelve hour interval during which the data was missed.

The missed Fire Tour data was sporadic and tours before and after verified no unacceptable conditions in the areas. In most cases other plant personnel were in the area and could have alerted plant emergency personnel in the event of abnormal conditions in the area. Furthermore other sensing and suppression systems in most of the areas were operable.

As noted above, the main significance of this event is related to the implications it has with respect to the veracity of station records. The Supply System requires and expects its records to be complete and accurate in all,aspects. Potentially generic challenge to any record or group of records is considered by Supply System management to have high significance with respect to the Supply System's mission and the public trust and confidence. Even though the above instances of missed data presented no physical, threat to the public, the Supply System considers these performance failures unacceptable.

There have been no similar events at WNP 2.
