Dear Mr. Madsen:
In accordance with 10 CFR 50.55(e), we are submitting the enclosed report of actions taken to correct a deficiency regarding the new fuel stcrage rack support design. We had previously informed your Mr. Tom Westerman of the deficiency on March 10, 1983. We have submitted an interim report logged TXX-3653 dated April 7,1983.
Supporting documentation is available at the CPSES site for your Inspector's review.

% TXX-3677 May 31, 1983 NEW FUEL STORAGE RACKS DESCRIPTION OF THE DEFICIENCY While verifying verticality, site engineering contacted the A/E j and supplier to evaluate a proposed design change for the new fuel storage rack anchors. Further investigation has indicated the existing anchors were installed without proper authorization. SAFETY ANALYSIS In the event the existing conditions had gone undetected, the structural integrity of the new fuel storage racks could not be assured during a seismic event. CORRECTIVE ACTION An approved anchoring design has been issued and implemented to correct the existing condition. Current construction training programs and procedures for concrete anchor installation preclude additional unauthorized installations. These programs have been implemented since the original installation of the new fuel storage racks. In addition, we have evaluated the possibility of other installations improperly authorized prior to the current program. Procurement and warehouse personnel have completed procurement document and inventory reviews. These efforts have indicated proper control of permanent and non-permanent (construction) anchoring devices. Further field efforts by site quality personnel have revealed no evidence which implies this deficiency is generic. - -}}
