On May 20, 1987 at 1520 hours0.0176 days <br />0.422 hours <br />0.00251 weeks <br />5.7836e-4 months <br />, the Turbine Room Sump effluent discharge flow sensor and recorder, DFR-700, was removed from service for routine calibration. It was not recognized at that time that the Turbine Room Sump sample compositor received input from the flow instrument. Due to problems encountered, the compositor remained inoperable overnight and the eight hour samples were not analyzed as required by the action statement of Technical Specification 3.3.3.9.

The error was discovered on May 21 1987 at 0730 hours0.00845 days <br />0.203 hours <br />0.00121 weeks <br />2.77765e-4 months <br /> and manual sampling was begun. The instrument was returned to an operable condition by 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br />.

To prevent possible recurrence, Instrumentation personnel who may become involved with this instrument have been informed of this finding. Also, a sign has been added to the recorder informing personnel of its input to the Technical Specification required compositor.

Descri tion of Event On May 20, 1987 at 1520 hours0.0176 days <br />0.422 hours <br />0.00251 weeks <br />5.7836e-4 months <br />, the Instrumentation and Control (I6C)

Section was calibrating the Turbine Room Sump effluent discharge flow recorder (EIIS/FR) for routine preventive maintenance. For this work, the flow sensor is disconnected from the recorder and test equipment is connected to supply a standardized simulated input. The calibration was not completed by t'e end of the shift and the test equipment was left connected and turned off. This action resulted in making the automatic sample compositor (EIIS/ASV) inoperable due to the simulated no-flow signal being applied.

The Chemical Section performs four-hour checks on the compositor receiver to verify automatic operation of the compositor. Due to abnormal work on the Turbine Room Sump causing very intermittent discharge flow, little increase in sample collection was expected. The compositor actuation was verified manually each time, but the automatic signal was not known to be inoperable.

However, by 0730 hours0.00845 days <br />0.203 hours <br />0.00121 weeks <br />2.77765e-4 months <br /> on May 21, 1987 when no increase in sample was noted, manual sampling was begun due to suspected failure of the automatic sampling. By 1045 hours0.0121 days <br />0.29 hours <br />0.00173 weeks <br />3.976225e-4 months <br />, the failure was confirmed by direct observation of flow from the sump with no automatic sample being taken by the compositor.

There were no inoperative structures, components or systems at the start of the event that contributed to the missed surveillance.

Cause of Event The cause of the event was the failure to recognize that the recorder supplies a signal input to the compositor, and to make contingency plans for removing the compositor from service. As the recorder's effect was learned during the calibration, the fact that the compositor being required by Technical Specification was not identified through job order evaluation (prior to job performance).

Anal sis of Event The compositor was inoperable approximately 23.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />. Sampling and analysis of the effluent flow was not performed for approximately 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />. This incident is considered as a missed surveillance and reportable under 10CFR50.73 due to the fact that eight-hour alternate analysis was not performed as required by the action statement of Technical Specification 3.3.3.9.

As., the Turbine Room Sump sample compositor is the last point monitored for radioactive discharge, the related front line radiation monitors were reviewed for that time period and found to be operable. The daily sample requirement of the NPDES permit was determined to be met. A special report was required to estimate flow for the time the recorder was being calibrated, which was submitted.

Corrective Actions When the Chemical Section notified I&C of the problem with the compositor, steps were taken to restore the recorder. The compositor was declared operable at 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br /> on May 21, 1987.

To prevent recurrence, the I&C supervisors and job order evaluation group have been informed of the findings in this system. Also, a sign has been added to the recorder informing personnel of its input to the Technical Specification required compositor.

Failed Com onent Identification None.
