0l1 0l2 OF 0l2 rext en ., M ,we r asuwnn During the month of February (1984), the testing requirements as required by Technical Spacification 4.3.7.11 for the performance of SI-072-201, " Monthly Functional Test of Off-Gas Hydrogen Analyzers AIT-06973A,B", were scheduled to be met by the performance of the quarterly (calibration) eurveillance procedure SI-072-301. The due date and violation date were, however. inadvertently omitted from the Surveillance Authorization (SA) cover sheet for the quarterly calibration procedure, SI-072-301, and as a result, the foreman was not aware that the viols *f an date for the monthly functional test was 2/25/84. Functional testing of Hydrogen Analyzer Channel A was completed on 2/23/84, two days before the violation date. Hydrogen Analyzer Channel B was functionally tested on 2/29/84, four days following the violation date. The missed surveillance for the Chrnnel B Hydrogen Analyzer was discovered at 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> on February 29, 1984 upon completion of the quarterly surveillance procedure SI-072-301. Hydrogen Analyzer Chrnnel A was properly surveilled and operational during this event.

A review of Unit 1 operating power history indicates the plant was at approximately 50%

power for nineteen hours on February 25, 1984, shutdown during February 26 and 27, 1984, in startup for four hours on February 28, 1984 and at a maximum power level of 45% on February 29, 1984. The Hydrogen Analyzers for the Off-Gas System are required to be functioning when the Off-Gas System and hence Unit 1 is operational.

Data recorded during the period of this event indicates the percent of H2 s recorded for (redundant) Channels A and B of the Hydrogen Analyzers shows no changes in the p:rcent of H2 by either channel. The H2 recombiner outlet temperature, as recorded during the event, indicates the recombiners were operational and that no abnormal H2 concentrations existed in the Off-Gas Stream. Furthermore, all twenty-four Off Gas System alarms and the six alarm functions (i.e. result in Off-Gas System isolation) rrmained operable. Had an excessive amount of H2 gas entered the Off-Gas System be-tw:en February 25 and February 29, 1984, while Unit 1 was operating, the missed sur-vaillance on Hydrogen Analyzer Channel B would not have prevented the system from functioning as it was designed.

Corrective actions were taken thru changes in Administrative Procedure AD-QA-422,

" Surveillance Testing Program", by the inclusion of the statement " Satisfies surveillance requirement due / / violation date / / ."

1 (Specify) in the REMARKS section of the Surveillance Authorization Cover Sheet when similar test-ing requirements are to be met by a similar procedure of different surveillance fre-qu;ncy. This change makes personnel aware of the surveillance requirement date and its corresponding violation date.

Since the Off-Gas System Hydrogen Recombiner functioned properly, no abnormal concen-tretions of H2 occurred and diverse system isolation / alarms existed. The health and c fety of the public was not affected.

This event was originally determined to be reportable per 10CFR50.73(a)(2)(i) in that functional testing of the Common Off-Gas System Hydrogen Analyzer Channel B, required by February 25, 1984 in accordance with Technical Specification 4.3.7.11, was not performed until February 29, 1984. Revision 1 of the Licensee Event Report is provided for additional information concerning the corrective actions taken as a result of this event.
