, August 10, 1982 j -Identification of Occurrence The stack gas was not continuously monitored as required by Technical i V . Specifications, paragraph 3 6.A.3 This event is considered to be a reportable occurrence as defined in the Technical Specifications, paragraph 6 9 2.a.2.

' ' Conditions Prior to Occurrence Power: Reactor - 1332 MWt Generator - 420 MWe Reactor Coolant Temperature - 5300F Description of Occurrence  :

On August 10, 1982 at approximately 1445 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.498225e-4 months <br />, the breaker for 'B' Stack Gas Sample Pump tripped. The sample flow decreased to zero. The breaker was reset

! at approximately 1447 hours0.0167 days <br />0.402 hours <br />0.00239 weeks <br />5.505835e-4 months <br /> at which time the stack gas sample flow was returned to n'ormal.

l Apparent Cause of Occurrence The occurrence resulted from an electrical trip of the heater overload protector en the motor controller. Further investigation to determine the cause of the electrical trip found that the stack gas sample system vent fan had been turned off and valve SGM-23 required adjustment in order to increase flow to the pump suction.

Analysis of Occurrence l

l The Stack Gas Sampling System monitors radioactive gaseous effluents released f rom the stack. Since the local radiation monitors and the off-gas radiation monitors showed no change before, during and af ter the occurrence, the safety significance of this event is considered minimal.

Licensee Event Report Pago 2 Reportable Occurrence No. 50-219/82-44/0lT Corrective Action Immediate corrective action was to return the stack gas samplo flow to normal.

Additional corrective actions taken were: 1) install "D0 NOT TURN OFF" tags on the stack gas sample system vent fan, 2) adjust the setting of valve SGM-23 to increase flow to the pump suction; this setting will now be checked three times weekly by chemical technicians, and 3) procedures were revised to assure that both Operations and Chemistry personnel used the proper valve line-up.
