Dear Mr. O ' Re illy :
PG LAR G AN TRY CRANE - GEAR MISALIGNMENT a
NO. 1 Uh2T SA LEM NUC LEA R GENERATIN G STATION On June ll, 1976 a verbal report was made to Region 1, Office of Inspection and Enforcement advising that during an inspection s,
it was discovered that there was a misalignment of gearing in the No. 1 Unit Polar Gantry Crane.
This report was in accordance with the provisions of 10CFR50.55(e).
=
The following is a detailed analysis and report on the subject:
~
While performing a service-inspection of the Polar Gantry Crane during turnover from the plant construction phase to the plant operating phase, excessive vibraticn of the main hoist was observed.
After investigating, the cause of the vibration was determined to be the misalignment of the hoist drum gear (drum assembly) ano pinion.
Corrective action consisting of realigning and securing the drum assembly, and dressing the gears has been initiated.
There was no affe^t to the safety or health of the operating staff or the general public.
The implications of this condition, if it were not corrected, are that the hoist assembly would be subjected to above normal wear and over an extended period of
=
years the load carrying capability of the crane would have been adversely effected.
The corrective action vill be comple ted by July 1, 1976.
