SUMMARY

OF OPERATING EXPERIENCE 02/01/85.

At 0000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br />s-the plant was In normal operation at 425 MWe (gross).

02/02/85 AT 0507 hours0.00587 days <br />0.141 hours <br />8.382936e-4 weeks <br />1.929135e-4 months <br /> the main generator was taken off line.

At 0548 hours0.00634 days <br />0.152 hours <br />9.060847e-4 weeks <br />2.08514e-4 months <br /> the reactor was driven su bc ri ti ca l.

At 1845 hours0.0214 days <br />0.513 hours <br />0.00305 weeks <br />7.020225e-4 months <br /> all control rods were fully inserted. After shutdown a spurious Reactor Protection System trip was experienced due to a f ai led LPRM (resulting in APRM 155 trip) at 2351 hours0.0272 days <br />0.653 hours <br />0.00389 weeks <br />8.945555e-4 months <br />.

(LER 85-04) 02/03/85 At-0402 hours the reactor vessel head vents were opened placing the plant in cold shutdown.

02/05/85 AT 0430 hours0.00498 days <br />0.119 hours <br />7.109788e-4 weeks <br />1.63615e-4 months <br /> the mode switch was placed in the refuel position.

02/07/85' The reactor vessel head bolts were detensioned.

02/09/85 The removal of the reactor vessel head was completed by 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br />.

02/10/85 At 0145 hours0.00168 days <br />0.0403 hours <br />2.397487e-4 weeks <br />5.51725e-5 months <br />.the steam dryer was removed from the vessel.

02/15/85 At 2io7 hours, defueling of the reactor vessel commenced.

02/16/85 Personnel erroneously utlllzed an Internally contaminated hose to flush a nonradioactive floor drain.

The effluent from the drain is routed to a holding tank.

Sampling of the tank confirmed no detectable contamination.

02/19/85 The reactor vessel was fully defueled by 0940 hours0.0109 days <br />0.261 hours <br />0.00155 weeks <br />3.5767e-4 months <br />.

(Normal DAEC refueling practice is' full core defuel to spent fuel pool.)

02/22/85 Plannod comprehensive refuellnq outage Inspection of the HPCI 3-tu r bi ne discovered cracked reversing chambers.

This problem has been reported previously in DAEC-unique reports.

(LER 85-07 pendino)

}

02/28/85 At the end of the month the refuel outage continued with the vessel defueled.
