FU :: 6 1986 Docket Nos.: 50-327 and 50-328 Mr. S. A. White Manager of Nuclear Power Tennessee Valley Authority 6N 38A Lookout Place 1101 Market Street Chattanooga, Tennessee 37402-2801
Dear Mr. White:
Subject:
Special Inspection of January 24, 1986 on Welding Concerns -
Sequoyah Nuclear Power Plant On January 21 to 24,1986, NRC staff conducted part of a special inspection to examine Bechtel's Audit program and TVA's weld reinspectfen program at Sequoyah, The staff identified several concerns which were discussed with your personnel at the exit interview. This letter documents those concerns.
Those concerns were as follows:
1.
Because of parallel efforts in performing reinspections while still providing submittals to NRC, reinspections were not being performed exactly in accordance with written comitmants.
Inspection procedures which were being used for PT and MT were written to ASME Section XI. The January 17, 1986, submittal to NRC speci,fied reinspections were to be to ANSI B31.1 and B31.7, 2.
In the " Program Description" submitted to NRC dated January 17, 1986, the terms " adequate for service" and " meet all ccmmit-ments and requirements" appear to be used interchangeably, These tems are not the same. NRC considers that the audit and reinspection program should first detcrmine if commitments and requirements are met. The next step would be to determine
" adequacy for service."
3.
The person in a supervisory / coordination position over the reinspection progran was the same person supervising inspection personnel during original construction. After questions were raised by NRC, that person was relieved of the responsibility.
