SUBJECT:
MEETING - TMI-1 STEAM GENERATOR REPAIR Purpose of Meeting A meeting was held at the Foster-Wheeler (F-W) offices located in Livingston, New Jersey on July 21, 1982 to discuss the qualification test prcgram for the.F-W sleeving process to be used in the TMI-1 steam generator restoration program. The objectivesof the meeting were to:
,1.
Present status of GPU, B&W and F-W sleeving program.
2.
Coordinate GPU program with NRC contractor program.

The meeting agenda'is attached hereto as enclosure 1.
. Significant Items The B&W test program should -provide objective data to support a confidence level of.99% in_the sleeving process based on quantitive pull test loads and leak ~ rate tests.
'B&W. test blocks are in preparation. Blocks C, D'and'E are on the critical path to: demonstrate acceptability prior to intiation of repairs. Se attached schedule - enclosure 2.
.B&W will prepare test blocks for the NRC program and F-W.
These blocks are behind schedule.
Preliminary, tests and evaluation by.B&W and F-W have been positive. Accept-ance criteria for pullout tests and leak rate have beep met. The expansion length has been established and explosive charge volumes determined.
F-W t
and B&W are ready to proceed to the QA. controlled test program.
The QA controlled. test program sequence, applied stress and sample size have been determined. Minor changes may be made as a result of NRC concerns.
The-test program details,-including procedures, are considered proprietary E-and will be transmitted to NRC with the appropriate affidant in accordance with 10 CFR 2.790 provisions.
'A meeting is scheduled at TMI-l on August 29, 1982 to discuss eddy current test results.-
.There will be a demonstration of the F-W explosively expanded sleeving process on a mock up SG at B&W, Mt. Vernon, Indiana facility on August 5,1982.
