A Contrary to the requirements of 10CFR50, Appendix B, Criterion IX, the Enrico Fermi 2 Final Safety Analysis Report Section B17.1.9, and the ASME Boiler and Pressure Vessel Code,Section III,1971 Edition, Winter 1971 Addenda, Appendix IX, Paragraph IX-3325, AS'IM E142 penetramers were not used to check the radiographic technique employed on shop fabricated welds.
Corrective Actio_n taken and the Results Achieved A review of Dravo radiographic film supplied to the Fermi 2 Project has been Over 4,000 film packages were reviewed and approximately 2,600 carpleted.
The problem were found to have the problem with the improper pentra:reter.

Disposit. ion for the welds will be based on the written for each group.

Disposition has been determined for film in the first three cat-carpleted.
Sixteen safety related welds were found to be in cate-egories noted above.

Dear Mr. ?!orelius:
Roquest for Extension of Time to Respond to NRC inspection Report 50-341/81-07 8
This letter is to document the granting of a request by Detroit Edison for additional tim'e to respond to NRC Inspection Report 50-341/81-07 This
'l' report covers the inspection conducted by Mr. K. D. Ward of NRC Region ill 1
at the Fermi 2 Site on June 16-19, 1981. We requested the extension to allow adequate time to complete our investigation. To reply within the allotted time would probably require the submittal of additional infor-f' mation at a later date.
Mr. J. Smith of your organization indicated by telephone on July 20, 1981, that the request for additional time was acceptable to the NRC. The response is now due on or before August 20, 1981.
m Very truly yours
