Perry Nuclear Power Plant Docket Nos. 50-440; 50-441 Tube Turns Nuclear Class I Flued Head Penetrations
[RDC 144(85)]
Dear Mr. Keppler:
This letter is an interim report pursuant to 10CFR50.55(e) concerning potentially deficient shop welds in containment pene-tration assemblies manufactured by Tube Turns, Inc. of Louisville, Kentucky.
Mr. J. McCormick-Barger of your office was notified by telephone on July 31, 1985 by Mr. Paul P. Martin of The Cleveland Electric Illuminating Company that this condition was being evaluated per Deviation Analysis Report 250.
Tube Turns, Inc. was also notified.
Flued heads are used to support and anchor process piping where it passes through a containment penetration.
During the leak testing of the assemblies installed in Unit 1, indication of leakage was identified in two (2) of the penetration assemblies (P-410 and P-411).
In both instances, the leakage occurred near the shop weld that connects the flued head to the process pipe.
These penetration assemblies including the weld to the process piping were supplied by Tube Turns, Inc. of Louisville, Kentucky.
The leak tests were subsequently repeated and no leakage was identified.
