R. McFarland of your office of a Potentially Reportable De-ficiency (PRD) at the Grand Gulf Nuclear Station (CGNS) construction site. The deficiency concerns installation of expansion anchors for conduit hangers, instrument process tubing, and air supply sup-ports without proper approval. An interim report of our progress in evaluating the extent of the deficiency and impact on safe operations of the plant is at-tached. We expect to complete our evaluation and provide you our final report on this deficiency by March 10, 1981. Yours trul fg J. P. McGaughy, Jr. EWC:mt Attachment cc: Mr. N. L.

of the deficiency has been expanded to include instrumentation, ' pipe hangers, electrical, electrical hangers, and General Mechan-i ical Corporation, a subcontractor for HVAC ductwork.

II. Resolution of Deficiency Conduct an investigation to determine the location of all con- , crete expansion anchors which have been installed in-restricted , areas, document the nonconformances and obtain engineering dis-4 position. l l Revise any procedures or other documentation, as necessary, to , preclude recurrence. i

Conduct training and retraining ( personnel.

III. Status of Resolution I , -The Constructor has completed the investigation and has routed

;

nonconformances to the Architect / Engineer for disposition, a The Constructor's Work Plan Procedure, " Installation, Inspection, and Documentation for Concrete Expansion Anchors", has been re-vised to require certification of all installers of expansion.

sonnel, and field engineers involved with the. installation of ex-pansion anchors. The retraining program includes the requirements

of the Work Plan Procedure and the restricted areas defined by ! the Specification. IV.
