SUMMARY

OF OPERATING EXPERIENCE 05-01-84 Normal plant operation at 64 MWe (gross).

At 1600 hours0.0185 days 0.444 hours 0.00265 weeks 6.088e-4 months , "B"

H022 Analyzer declared inoperable.

" 02-84 At 1650 hours0.0191 days 0.458 hours 0.00273 weeks 6.27825e-4 months , a low reading was noted in the "C" main steam line flow.

At 1811 hours0.021 days 0.503 hours 0.00299 weeks 6.890855e-4 months power was reduced to 25% for investigation of the "C"

steam line.

At 2040 hours0.0236 days 0.567 hours 0.00337 weeks 7.7622e-4 months testing discovered "C"

inboard Isolation valve was inoperable.

MSL "C" was isolated with outboard MSIV.

(LER 84-016) 05-04-84 At 1000 hours0.0116 days 0.278 hours 0.00165 weeks 3.805e-4 months , HPCI auto-started due to personnel error while performing surveillance testing of the reactor low-low water level Instrumentation. The situation was diagnosed immediately and HPCI was-returned to normal standby status.

(LER 84-017) 05-07-84 At 1602 hours0.0185 days 0.445 hours 0.00265 weeks 6.09561e-4 months , the outboard valve of RCIC steam supply unexpectedly isolated during surveillance testing of steam leak detection instrumentation. A differential pressure relay was jarred when the relay cover was remo,ved.

(LER 84-018) 05-16-84 Normal controlled shutdown commenced for Investigation and repair of MSIV's.-

At 1809 hours0.0209 days 0.503 hours 0.00299 weeks 6.883245e-4 months , the "A" 02 analyzer was recalibrated for de-Inertion of drywell.

Due to previous inoperability of the "B"

02 analyzer, a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months voluntary LCO was commenced. An unusual event was declared.

05-17-84 Generator taken off-line at 0450 hours0.00521 days 0.125 hours 7.440476e-4 weeks 1.71225e-4 months .

At 0610 hours0.00706 days 0.169 hours 0.00101 weeks 2.32105e-4 months the reactor was subcritical.

At.1622 hours0.0188 days 0.451 hours 0.00268 weeks 6.17171e-4 months , the reactor head vents were opened, placing reactor in cold shutdown.

At 1704 hours0.0197 days 0.473 hours 0.00282 weeks 6.48372e-4 months , the unusual event for inoperable 02 analyzers was cancelled.

05-21-84 At 0507 hours0.00587 days 0.141 hours 8.382936e-4 weeks 1.929135e-4 months , a spurious half Group V signal resulted in isolation of the Reactor Water Clean-Up system.

At 0528 hours0.00611 days 0.147 hours 8.730159e-4 weeks 2.00904e-4 months the RWCU system was returned to normal status.

(LER 84-019 pending) 05-31-84 Outage for MSIV repair continues. Reactor in cold shutdown.
