SUMMARY
OF OPERATING EXPERIENCE OPERATION:
The plant began the month at full power, sustained one inadvertent trip on 10-2-79, and shutdown on 10-12-79 to plug small leaks in the 1. and D steam generators amounting to 125 gallons per day and to inspect seismic hangers and restraints inside the containments.
A positive displacement charging pump packing leak was discovered and repaired that had been responsible for periodic increases in Auxiliary Building airborne activity levels.
Temporary backup RCS cooling hoses were placed in the field pending resolution of the seismic integrity of hanger support under block walls.
MAJOR SAFETY-RELATED MAINTENANCE:
Work continued on improvement modifications to the Plant Security and Fire Protection Systems.
Work continues on the program of upgrading pipe hanger and restraints for seismic loading.
An inspection was conducted on the seismic hangers and restraints inside the containment.
Some repairs were made as defects were found.
Work was completed en repairing hanger SA-83 to correct its seismic interface with a cinder block wall in the RHR pump room area.
Work was completed on cteam generators A and D eddy current testing. Work began on steam generator tube plugging operation.
Work continued on a program to investigate stress corrosion cracking on stagnant water lines.
Completed the periodic overhaul of the electric tire pump.
Discovered and repaired a small surface crack found on the suction line pipe elbow of the south safety injection pump.
LICENSE CHANGES:
None.
MISCELLANEOUS:
During the steam generator eddy current testing, some contractor personnel were involved in radiological control incidents.
One person received a dose of 2.9R which is near the quarterly dose limit of 3R.
A few persons received some exposure without proper dosimetry.
These circumstances are now under reviet An investigation began on the seismic integrity of some cinder block walls to which seismic hangers are attached.
