Attcchment to AECM-81/217 Pag 2 1 of 1 FINAL REPORT TO PRD-80/46 1- I. Description of Deficiency Expansion anchors for conduit hangers, instrument process tubing, and air supply supports have been installed without prior engineering approval, as required by the specification. The scope of the deficiency has been expanded to include instrumentation, pipe hangers, electrical, electrical hangers, and General Mechanical' Corporation, a subcontractor for HVAC ductwork.

11, Analysis of Safety Implientions 1

Our Architect / Engineer performed calculatious to determine the adequacy of the structural integrity of the columns and of the local ef fects to the attachments. The evaluation resulted in the conclusion that, had the conditions remained uncorrected, they would not have af fected the safe operation of the nuclear plant.

III. Corrective Actions-Taken An investigation to determine the location of all concrete expansion anchors which have been installed in restricted areas has been completed, the nonconformances documented and engineering disposition _ obtained.

The Constructor's Work Plan Procedure, " Installation, Inspection, and Documentation for Concrete Expansion Anchors", has-been revised to require certification of all installers of expansion anchors. This certification signifies the installers have completed training and testing on installation of expansion anchors.

Retraining has been conducted for all craf tsmen, non-manual personnel, and field engineers involved with the installation of expansion j anchore. The retraining program includes the requirements of the Work

[ Plan Procedure and the restricted areas defined by the Specification.

Corrective actions are tracked by our Constructor's Management Corrective

! Action Request (MCAR)-94.
