This letter confirms the conversation on July 19, 1985, between Mr. E. Greenman of my staff and Mr. B. Stevenson of your staff related to the July 17, 1985 discovery of improperly installed RHR cooling isolation switches on LaSalle Unit 1. With regard to the matters discussed, we understand you have taken or

~w ill take the following actions on LaSalle Units 1 and 2.

1. ReviewtheentirelistofDrawingChangeRequests(DCR's)anddetermine those DCR's that have been rejected or cancelled.

2. Review all rejected or cancelled DCR's and determine the status of their disposition.

3. For those DCR's which have been rejected or cancelled or for which the disposition is unknown,' verify that critical drawings onsite are properly annotated to show the present status of the associated system and/or that drawing aperature cards show they are affected by a DCR. All remaining open DCR's will be reviewed within two weeks of startup.

4. Implement a documented review of all EQ work requests prior to performing the work to ensure that qualification is-preserved. This review applies to all EQ work requests initiated subsequent to July 19, 1985, and will contin ~ue 'until the maintenance procedures have been updated to reflect EQ requirements.-

5. Implement a documented review of surveillances on EQ equipment prior to performance to ensure'that qualification is preserved. This review applies to all surveillances on EQ equipment initiated subsequent to July 19, 1985, and will continue until the surveillance procedures have been updated to reflect EQ requirements.

6. By August 5,1985, complete a documented review of one EQ component of each type for all EQ binders that have been issued to the site and for which a site review has been performed. This review will ensure that all appropriate EQ requirements were accomplished during installation.

7. By September 2,1985, complete a documented review of all EQ binders that have been received by the site, but that have not yet been reviewed, and ensure that appropriate EQ requirements were accomplished during installation.

The improper RHR shutdown cooling high flow isolation switch installation was the result of improper closure of a DCR and drawings or aperature cards not being correctly updated to show the present status of systems. Consequently, we understand that LaSalle Units 1 and 2 will remain in cold shutdown until items 1 through 5 are complete and you provide the resident inspector office with the results of your reviews and conclusions.

Please contact us imediately if your understanding differs from that set forth above.
