SUMMARY
OF OPERATING EXPERIENCE Docket No.:
50-266 Unit Name:
Point Beach Unit 1 Date:
June 6, 1985 Completed By:
C. W. Krause Telephone:
414/277-2001 The Unit 1 refueling and maintenance outage completed Weeks 4 through 8 during the month with the control rod guide tube flexureless insert and split pin modification being com-pleted.
Other major work completed includes secondary heat exchanger sludge lancing and tube plugging, disassembly and inspection of the "B" circulating water pump, repairing 1MOV-856A, residual heat removal suction valve to the refueling water storage tank, repairing the "A" and "B" main feed pump rotating assemblies, inspecting and repairing 500 kip and 800 kip snubbers and repairing the main steam stop valves.
Reactor Engineering completed fuel sipping and visual inspection of the spent fuel.
Assemblies were sipped that Westinghouse believed would be likely candidates for leakers.
Three leaking assemblies were found and one of them had visible damage.
The assemblies were also inspected for evidence of " baffle jetting."
Only one fuel assembly was found with evidence of potential " baffle jetting" effects from an inside corner of the reactor core barrel.
After consulting with Westinghouse, the decision was made not to modify any fuel assemblies to mitigate baffle jetting effects during the next cycle.
On May 22, 1985, Operations refueling test, ORT #3,
" Loss of AC & Safety Injection," was successfully performed.
During the recovery from the outage, control rods F12 and J4 stuck in an intermediate position and were not freed using the control rod drive mechanism.
The reactor head has been removed and the internals are being dismantled manually for further investigation.
