f Per Technical Specification 6.9.1.7, the following is a summary of effluent monitoring instrumentation inoperable for a period of time longer than specified in Technical Specifications 3.3.3.9 and 3.3.3.10, including an explanation why the instrumentation was not repaired in the specified time frame.

1.

Essential Service Water /RCFC Outlet Monitors 1RE-PR002 and 1RE-PR003 were inoperable from 0610 on 11-8-84 to 0500 on 7-7-85; greater than the 30 day limitation.

Due to piping design problems, these monitors were unable to attain adequate flow to consider them operable.

A major engineering design change, including a formal engineering review and modification documentation, was necessary to correct the problem; this process accounted for the time delay in repairing the inoperable monitors.

For the duration of the monitors' inoperability, grab samples were obtained and analyzed every 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months as required by Technical Specifications.

2.

Efficent System Flow Rate Measuring Device LOOP-VA019 was inoperable from 1216 on 11-19-84 to 1619 on 1-19-85; greater than the 30 day limitation.

LOOP-VA019 was inoperable for an extended period due to extensive mechanical repairs and subsequent testing needed to correct the damaged flow sensor.

For the duration of the sensor's inoperability, vent stack flow rate was determined every 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months as required by Technical Specifications.

3.

Noble Gas Activity Monitors (Gas Decay Tank Effluent) ORE-PR002A and ORE-PR002B were inoperable from 1845 on 3-30-85 to 2213 on 4-27-85; greater than the 14 day limitation.

The extended inoperability was due to electrical noise problems causing spurious alanns on the monitor. Due to the amount of investigation required to determine the source of the electrical noise, the monitor was not repaired within 14 days.

No Gas Decay Tank releases were performed during the period of the monitor inoperability.
