Tritium Release Reported for 1990 and 1991 The amount of tritium released for the years 1990 and 1991 were incorrectly reported. The reported values and the correct values are f
listed in the table below.
The value for Station Vent Stack flow used in calculating the amount of tritium released was incorrect. The ve.lue used was to low by a factor of one hundred. The error was identified during a audit performed by Corporate Assessment in May of 1992.

_ RESIDUAL HEAT PEMOVAL
=i:
SERVICE WATER PROCESS RADIATION MONITOR I
DESCRIPTION OF EVENT:
- l On March 2, 1992, Unit 2 was in Operational Condition 5 (Defueled) at 0%
power. _ At approx 4mately 0135 hours0.00156 days <br />0.0375 hours <br />2.232143e-4 weeks <br />5.13675e-5 months <br />, the timeclock for the Unit 2 "B" Residual Heat Removal (RHR) Service Water (WS) Process Radiation Monitor (PRM) was exceeded. The timeclock was entered on February-1, 1992 at 0135 hours0.00156 days <br />0.0375 hours <br />2.232143e-4 weeks <br />5.13675e-5 months <br /> due to RHR WS valve and Heat Exchanger wark.
While this work was going on, other work was being_ started on February 10,1992 that also made the-PRM inoperable. This work was on a Primary Containment Vent and Purge Vacuum Breaker and it required that a length of crble tray be removed.
The electrical cables remained connected and in place, but it was determined that all cable from that tray would not be able to withstand a seismic-event. 'Therefore the cables from that tray and the associated
~
equipment were conservatively considered inoperable even though the equipment was still functional. While'this work was going on, the work on the RHR WS valve and Heat Exchanger was co.tpleted and that source for the inoperable PRM was cleared, but the PRM was still inoperable due to the work on the Primary Containment Vent and Purge Vacuum Breaker. This work continued until the 6th of March, 1992 at 1450 hours0.0168 days <br />0.403 hours <br />0.0024 weeks <br />5.51725e-4 months <br /> at which time the cable tray was replaced and the PRM was returned back to service.
[
However, the return to service of the PRM was past the required 30 day timeclock.
APPARENT CAUSE OF EVENT 7
The cause of this event was the. length of time that was needed to' complete the work on the Primary Containment Vent and Purge Vacuum Breaker, that is, the repair work on the 2VQO29 extended beyond what was originally anticipated to ecmplete the valve actuator replacement. This overlap created a situation that did not allow the return of the PRM to operability before-the timeclock was exceeded.
CORRECTIVE ACTION:
On March 6, 1992_at 1450 hours0.0168 days <br />0.403 hours <br />0.0024 weeks <br />5.51725e-4 months <br />,.t"he cable tray was replaced and the PRM was returned to service.
In addition,-this. event is being placed in the Semi-Annual' Effluent Report as required byfthe Technical Specifications, c
