SUMMARY
[ JULY 1993 l t UNIT 1 l l' Unit I remained in Mode 6 at the beginning of July. On July.5, the fuel ! assembly that had tilted over because of foreign material on the core { plate, as reported last month, was removed from the core and placed in l the spent fuel pit. On July 7, the decision was made to offload or l l reposition fuel assemblies in the Unit 1 core to allow 100 percent core ! plate inspection. At 2345 Eastern daylight time (EDT) on July 7,. the core offload was initiated. At 0948 EDT on July 8, the core had been offloaded except for two assemblies. The lower core plate inspection was completed with no additional problems identified. At 2058 EDT on July 8, : che reload of the Unit I core was initiated. On July 12 at 0346 EDT, the core reload was completed. On July 13 at 0549 EDT, all control rods had : been latched. Unit i remained in Mode 6 at the end of July. The i scheduled date for generator synchronization is November 19, 1993. {; UNIT 2 > 1 Unit 2 remained in Mode 5 during the entire month of July as a result of l inspection / repairs on secondary side piping as a result of erosion / corrosion problems. The scheduled date for generator , synchronization is September 10, 1993. ' l 1 POWER-OPERATED RELIEF VALVES (PORVs) AND SAFETY VALVES
