SUMMARY

OF OPERATING EXPERIENCE 11-1

. At the beginning of the report period the plant was operating at 237 MWe.

The plant was being operated at reduced power levels due-to lack of system

. demand.

11-4 Control rod group 36 was withdrawn to position 48. A power increase 'was begun.

11-5.

The plant was operating at 341 MWe, 11-6.

'During normal operation while performing an operational inspection, a leak was discovered in the reactor water cleanup system outboard of both isolation valves.

R0 Report 81-041 11-14

-During a weekly control rod exercise surveillance test, an overtravel alarm was received for control rod 26-15, indicating the CRD had uncoupled.

R0 Report 81-042 11-17 During power operation, the instrument line drain valve, V-18-20, for "B" scram instrument volume level switch LS-1861 was found locked open.

i R0 Report 81-039 11-18 During normal operation, it was found that reactor water cleanup system return isolation valve M0V 2740 would not cycle.

R0 Report 81-040 11-24 During normal operation secondary containment-isolation' damper IV-AD-15B began cycling and was removed from service.

R0 Report Pending 11-24 While testing the "A" control building standby filter unit, isolation. damper IV-AD-31A was found inoperable.
