Office of Inspection and Enforcement IE: II: JRH Region II - Suite 3100 50-424/79-11 101 Marietta Street 50-425/79-11 Atlanta, GA 30303 File: X7BG10 Log: GM-480 ATTENTION: Mr. C. E. Murphy Gentlemen:

The Georgia Power Company wishes to submit the following information concerning the noncompliances discussed in your inspection report number 50-424/79-11 and 50-425/79-11.

A) Infraction " Backfill Moisture Control" The Bechtel Power Corporation has reviewed the data for the questionable backfill and have detcrmined that the backfill meets their speci-fication requirements. The " oven dry" method has always been used in parallel with the " speedy" method and was the criterion for final acceptance of back-fill placed. The "speedie" moisture machine testing has been deleted as a method of testing backfill at Plant Vogtle Units 1 & 2. The " pan dry" method of testing will be utilized for future tests with additional material taken from one of the test holes for an " oven dry" analysis. The results of the

" oven dry analysis" will be plotted with the results of the " pan dry" tests and will form tt:? basis for final acceptance. The construction specification and field procedure CD-T-01 will be clarified to alleviate future problems in this area.

B1 Deficiency " Backfill Work Stoppage" A " Work Stop Order" was issued June 13, 1979 for Category I backfill. This order was rescinded on July 27, 1979 after Bechtel Power Corporation reviewed and accepted test data for the backfill. Additional training has been implemented in the area of work stoppage.

Georgia Power is presently in full compliance.
