SUMMARY

OF OPERATING EXPERIENCE 4-1-83 Plant in Refuel Mode, all fuel removed from vessel.

4-4-83 Suspended fuel movement due to "A"

IRM determined to be not fully inserted.

("D" and "E"

IRMs were Inoperable at this time).

.4-5-83

'A" 1RM' determined operable following evaluation.

4-8-83 Reactor scram 8 0758 during design change problems.

8 1417 reactor scram-from APRM A & B (LPRM 32-33-3A falled upscale).

4-9-83 1813 Core fully reloaded and core verification commenced.

1950 reactor In Shutdown Mode.

4-10-83 Core verification completed satisfactorily.

Fuel pool to reactor cavity gates Installed.

4-11-83 Secured draining reactor cavity, separator being lowered into cavi ry.

4-12-83 Steam dryer in place.

4-13-83 Reactor head In place, commenced ralsIng reactor vessel water level to flange.

4-14-83 "E"

1RM returned to operable status.

4-19-83 Integrated Leak Rate Test completed satisfactory (2 MSIVs, Drywell Water Cooling Water Supply A and B side control valves, Drywell and Torus Nitrogen Makeup valve CV-4311, Steam Line Drain Valves MO-4423 and MO-4424, RCIC Steam Supply Valves MO-2400, MO-2401 a nd Standby Liquid Control check val ve V-26-9 were repaired following LLRT).
