SUBJECT: NRC INSPECTION REPORT 50-458/93-04

'

This refers to the inspection conducted by Mr. M. Runyan and the inspectors

!

identified in the enclosed report, of this office on March 29 through April 2,.

1993. The inspection included a review of activities authorized for your

River Bend Station facility. At the conclusion of the inspection, the

!

findings were discussed with those members of your staff identified in the

l

enclosed report.

!

This inspection examined the implementation of your program to meet your

'

comitments to Generic Letter 89-10 " Safety-Related Motor-0perated Valve

!

Testing and Surveillance." We considered the implementation of your motor-

operated valve program to be generally in accordance with your comitments to

,

{

Generic Letter 89-10.

An improper post-test review of diagnostic test data was considered to be in

l

violation of. Criterion XI of Appendix B to 10-CFR Part 50.

This violation is

l

not being cited because the criteria in paragraph VII.B.2 (for licensee-

'

identified violations) of Appendix C to 10 CFR Part 2 of the NRC's " Rules of

Practice," were satisfied. This violation was an isolated occurrence and the

licensee staff-took prompt and effective actions to correct the problem.

i

An unresolved item was identified concerning a potential operability problem

-!

with Valve ICCP*MOV138.

It is our. understanding that you comitted to develop '

5

a corrective-action plan to address this valve. Another unresolved item

concerned several of the design assumptions made in design calculations

,

estimating the capability of your motor-operated valves. _ It is also our ' .

,

understanding that you comitted to validate or revise these assumptions by

'i'

July 1,1993,. based on an analysis of your motor-operated valve test data.

,

This issue is of concern because the assumed values in your calculations did

3

not appear conservative and, if changed, could result 'in operability problems.

-!

for some of your more marginal motor-operated valves.

If your understanding

of these comitments differs. from ours, please contact me imediately.

In accordance with 10 CFR Part 2.790 of the NRC's " Rules of Practice," a copy

i

of this letter and its enclosure will be placed in the NRC's Public Document

Room.
