08-07-84 At 1504 hours0.0174 days <br />0.418 hours <br />0.00249 weeks <br />5.72272e-4 months <br /> diesel generator 1G-31 was declared inoperable due to room ventilation supply fan IV-$F-20 being inoperable due to SV-7000A which affected the fan control. This commenced a 7-day LCO.

At 1824 hours0.0211 days <br />0.507 hours <br />0.00302 weeks <br />6.94032e-4 months <br /> 1G-31 was restored to operable status ending the 7-day LCO.

08-08-84 At 0319 hours0.00369 days <br />0.0886 hours <br />5.274471e-4 weeks <br />1.213795e-4 months <br /> surveillance testing discovered that the electrical supply breaker to the RCIC steam supply valve MO-2404 tripped out each time tho valve was closed.

The valves torque switch was out of adjustment. RCIC was declared inoperable, commencing a 7-day LCO.

At 1414 hours0.0164 days <br />0.393 hours <br />0.00234 weeks <br />5.38027e-4 months <br /> RCIC was f ully operable ending the 7-day LCO.

08-20-84 in association with repairs to the off-gas chlller a small volume of glycol (on the order of 1 quart) passed into the red wa ste system.

This resulted in the total organics concentration exceeding administrative limits. Processing of the effluent is being Investigated.

At 1717 hours0.0199 days <br />0.477 hours <br />0.00284 weeks <br />6.533185e-4 months <br /> the electric fire pump was declared inoperable when It was found that there was a break In the air line to the mlnlmum flow valve.

This commenced a 7-day LCO.

By 2229 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.481345e-4 months <br /> the air line was repaired ending the 7-day LCO.

08-21-84 At 0530 hours0.00613 days <br />0.147 hours <br />8.763227e-4 weeks <br />2.01665e-4 months <br /> the diesel fuel oll transfer pump IP-44A was found to exceed the upper IlmIt of ASME flow rate specifications.

The corresponding diesel generator was conservatively declared inoperable beginning a 7-day LCO.

By 1138 hours0.0132 days <br />0.316 hours <br />0.00188 weeks <br />4.33009e-4 months <br /> Plant Performance engineers determined that the pump was fully capable of performing its function thus ending the LCO on Inoperability of the diesel generator.

At 1148 hours0.0133 days <br />0.319 hours <br />0.0019 weeks <br />4.36814e-4 months <br /> a personnel error resulted in secondary containment being momentarily violated via the railway airlock.

flow requirements.

The pump was declared Inoperable commencing a 7-day LCO.
