Summary of Operations for _,

MARCH

,'1982' From March 1 to March 26, unit was shutdown for refueling outage. At 0507

-hours on March 26, the reactor was brought critical and plant heatup com-menced. Experienced increase in Relief Valve tail pipe temperatures and unit was brought sub-critical at 0553 hours0.0064 days <br />0.154 hours <br />9.143518e-4 weeks <br />2.104165e-4 months <br />. Discussed relief valve tail-pipe temperatures with vendor who recommended going to higher pressure.

Reactor was taken critical again at 1153' hours. At 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br />, RV-203-3A lifted at approximately 30 psig. The unit was immediately shutdown.

On March 27, after repairs to relief valves were completed, the reactor was taken critical-at 702 hours0.00813 days <br />0.195 hours <br />0.00116 weeks <br />2.67111e-4 months <br />. At 2115 hours0.0245 days <br />0.588 hours <br />0.0035 weeks <br />8.047575e-4 months <br />, a shutdown was initiated due to reactor water level-indication problems. Mode switch was placed in shut-down at 0412 hours0.00477 days <br />0.114 hours <br />6.812169e-4 weeks <br />1.56766e-4 months <br /> on March 28, 1982. The reactor was again brought. critical l,

.at 1652 hours0.0191 days <br />0.459 hours <br />0.00273 weeks <br />6.28586e-4 months <br /> on March 28, and a scram on high IRM's at 1944 hours0.0225 days <br />0.54 hours <br />0.00321 weeks <br />7.39692e-4 months <br /> occurred.

The reactor was brought critical at 0852 hours0.00986 days <br />0.237 hours <br />0.00141 weeks <br />3.24186e-4 months <br /> on March 29, and increased pressure to approximately 150 psig in order to test HPCI, RCIC and ADS.

On March 31, at 2400 hours0.0278 days <br />0.667 hours <br />0.00397 weeks <br />9.132e-4 months <br />, the reactor was at approximately 10% power-l awaiting a turbine generator roll.
