The Georgia Power Company wishes to submit the following information concerning the violation discussed in your inspection report 50-424/84-04 and 50-425/84-04:
Violation 50-424/84-04-01, " Failure to Follow Procedure for Concrete Ex-1 pansion Anchor Inspection" - Severity Level V.
(1) Georgia Power Company acknowledges the conditions identified in the violation in that one wedge anchor in each of two base plates were found at less-than-specified torque value; however, Georgia Power Company denies that the conditions are due to a failure to follow inspection procedures.
(2) Georgia Power Company is reviewing' avail'able. literature and test results on concrete expansion anchor studies which in-dicate that relaxation of wedge ~ anchors may occur within a relatively short time following the application of preload. ine torque.~ Georgia Power will conduct an evaluation'to determ if this phenomenon may have contributed to the " discrepancies" found by the USNRC Inspector. The studies being reviewed show that the relaxation of the bolt does not affect the strength of the anchor..
(3) A review has been conducted of Vogtle Procedure GD-T-27,
" Installation of Concrete Expansion Anchors", and of the inspection documentation for the concrete expansion anchors speci#ied in the violation. The inspector who conducted both inspections is a highly respected individual whose werk is extremely thorough and accurate. Georgia Power Company is 9407050328 840620 PDR ADOCK 05000424
