ATTN: Mr. Cordell Reed

Senior Vice President

Post Office Box 767

Chicago, IL 60690

Gentlemen:

l

This refers to the inspection conducted from June 1 through 20, 1989, at the

The Inspection concerned an event (ori

l

Braidwood Station.

50-456/89017(DRP);50-457/89017(DRP))ginallydiscussed

'

in Inspection Report

in which emergency

core cooling system (ECCS) operability was affected by a mispositioned-

isolation valve. Details of the event, as well-as details of two previous

events involving mispositioned ECCS valves, were discussed during an

enforcement conference held in the NRC Region III office in Glen Ellyn,

,

l

Illinois on July 11, 1989. The enclosed copy of our report identifies areas

discussed during the meeting.

I

As discursed during the enforcement conference, although the events involved

'

oifferent circumstances, we are concerned with the effectiveness of the

controls you presently have in place to ensure the continuous operability

of all ECCS equipment. We understand you are presently reviewing these

controls and request that you discuss any changes you have made or plan to

l

make to your program in your response to this violation.

,

l

Based on the information obtained during the inspection and provided at the

i

enforcement conference, we have concluded that the safety significance of the

most recent valve mispositioning event, even when considered in conjunction-

with the two previous events, does not warrant escalated enforcement' action.

However, Braidwood may be subject to escalated enforcement upon discovery

of additional valve mispositioning which affects ECCS operability.

In accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2,

. Title 10, Code of Federal Regulations, a copy of this letter and-its

enclosures will be placed in the NRC Public Document Room.
