Docket No. 50-461

Illinois Power Company

ATTN:

Mr. J. S. Perry

Senior Vice President

Clinton Power Station

Mail Code V-275

P. O. Box 678

Clinton, IL 61727

Dear Mr. Perry:

This letter refers to the inspection conducted by Mr. H. A. Walker and others

of this office from July 6 through August 3,1993, and further discussions at

a meeting in Region 111 on August 24, 1993. The inspection included a review

of authorized activities for your Clinton Power Station. At the conclusion of

the inspection, the findings were discussed with those members of your staff

identified in the enclosed report.

Areas examined during the inspection are identified in the report.

Within

these areas, the inspection consisted of selective examinations of procedures

and representative records, interviews with personnel and observation of

activities in progress. The purpose of the inspection was to determine

whether activities authorized by the license were conducted safely and in

accordance with NRC requirements.

The inspection verified that engineering activities at Clinton Station were

being conducted safely and in accordance with NRC requirement.

The inspection

team also concluded that engineering and technical support function

performance was good with improvements noted over our last engineering and

technical support inspection.

While improvements were observed, we are concerned with the apparent lack of

rigor in evaluating damage to residual heat removal system pipe restraints and

their impact on system operability.

In your safety assessment, the RHR

restraint problems were individually considered minor; however, the number of

restraint damage problems combined with the damage found in the same areas,

indicated these problems may have been significant.

Based on this inspection's results, certain of your activities appeared to be

in violation of NRC requirements, as specified in the enclosed Notice of

Violation (Notice). The violation is of concern because the failure to

determine and correct the cause of the RHR pipe support damage could result in

similar and more significant failures.
