I Gentlemen:

On July 29. 1981, in our report logged TXX-3374, we notified you of a '

deficiency involving the componert supports associated with the auxiliary l pii.ing systems for the CPSES Diesel Generators which we deemed reportable j unt er the provisions of 10CFR50.55(e) . This item was subsequently identified '

by our last report logged TXX-6435, dated May 13, 1937, as an item for which a final report had been issued but the Original completion date for the implementation of corrective actions has elapsed but the implementation of those actions is still in progress. This report is submitted to status the impicmentation of corrective actions, t in ar report TXX-3415 dated October 2,1981, we advisea you that all corrective actions would be completed prior to fuel delivery to site.

Corrective action implementation for the Unit 1 "A" and "B" train diesel i generator pipe supports was completed on June 30, 1983. The Unit 2 "A" train {

diesel generator pipe supports were completed on January 15. 1986. Rework of  :

the Unit 2 "B" train diesel generator pipe supports has been completed, i although Nonconformance Report (NCR) M85-201621 related to these supports is scheduled for closure by November 18, 1987.

l I

Delay in the completion of the rework for the Unit 2 diesel generator pipe supports can be attributed to deferred engineering and construction activities  ;

in Unit 2 in support of Unit 1. l l
