Radiographic film for reactor vessel CRDM housing welds supplied by Westinghouse does not meet the requirements of ASME Section III Appendix IX.
Initial Report Or June 3,1981, Mr. J. Bryant of NRC Reaion II, Atlanta, GA, was notified of this deficiency by Messers. W. O. Henry, J. E. Cavender, and J. K. Berry of Duke Power Company, Charlotte, NC 28247. This notification was a result of i
potentially reportable items CA-81-19 and MC-81-ll.
30-day Follo.-Up Report
~
Westinghouse determined on June 24,1981 that 13 RT films at Catenba and 11 RT films at McGuire exceeded the film density requirements. These welds will require additional volumetric examination by Westinghouse. This work is expected to start about August 15, 1981, when the Catawba reactor vessel head can be removed. The Catawba resident NRC inspector was present during the film evaluation by Duke and Westinghouse.
)
One film for a CRDM weld was not found in the McGuire records and will also be included in the reexamination.
Westinghouse is continuing their technical. evaluation of the radiograph tech-nique used. Also a CRDM mockup is being made to evaluate different volumetric examination techniques.
A final report will be provided by December 15, 1981.
