July 15,1992 COMPLETED BY; Glenn Davis TELEPHONE:

817 897-5277 MONTH: JUNE 1992 06/01 0000 Unit started.he month in Mode 1, with the reactor operating at approximately 100 percent of rated thermal power.

06/f>J 0215 A plant shutdown was initiated as required tsy plant Technical Specifications after one of two compressors associated with Train A of tle Control Room HVAC system tripped and could not be restarted, Train 8 of the Control Room HVAC system had yeviously been removed from service for corrective maintenance.

(

0250 A Notification of Unusual Event (NOUE) was declared following initiation of tha plant shutdown.

1 0640 The plant shutdown was terminated wnh tho reactor at approxims.le!y 8 percent of rated thermal l

power after Train A of the Control Ro.3m HVAC was retumed to service.

i 0823 The NOUSE was terminated.

1300 Reactor power increase initiated; however, power was required to remain below 50 percent to allow stabilization of tM reactor core flux distribution.

06/05 0542 Commenced increase to 100 pr rcent of rated thermal power.

06/11 0528 The reactor was manually tripped when both niain feedwater pumps tripped due to problems in printed circuit cards in the solid state protection system (SSPS).

06/13 0550 Achieved criticality and began power increase after replacement of several SSPS circuit cards and a relay.

06/23 1948 A thunderstorm damaged transformer 1ST re6utung in the safeguards busses transferring to the attemate power supply and the blackout suquencer actuating.
