""""Nddk*bieO'***" S April 30,1985 '66-298 Director, Nuclear Reactor Regulation Attention: Mr. Domenic B. Vassallo, Chief Operating Reactors Branch No. 2 Division of Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Vassallo:

Subject:

Detailed Control Room Design Review (DCRDR) -

In-Progress Audit Report Response

Reference:

1) Letter from J. M. Pilant to D. B. Vassallo, dated February 4, 1985, "NUREG-0737, Supplement 1 -

Detailed Control Room Design Review Summary Report" Your letter of March 20, if65, requested that the District provide our NRC Project Manager with a schedule for addressing various recommendations not already resolved in our DCRDR Summary Report of Reference 1. It is anticipated that the Supplement to our Summary Report will be submitted approximately February,1986. The District must implement an action plan with considerable scope in order to address the staff's recommendations. The most probable action plan is outlined in Attachr.ient 1, including the estimated completion date for each of the various phases. The scheduled dates for completion provided herein are coasidered estimated dates in accordance with our April 15, 1983, response to NUREG-0737, Supplement 1. As defined in Attachment 8 to that document, our NRC Project Manager will be kept informed of all substantive changes in the implementation schedule.

It should be noted that the District will not directly impleraent some of the staff's recommendations. For example, the staff recommends that Regulatory Guide 1.97 instrumentation be available prior to EOP implementation; however, the District is under Order to implement the EOP's prior. to September,1985, before the Regulatory Guide 1.97 efforts are complete. If the staff wishes to discuss-any of the enclosed information in further detail prior to submittal . of our Supplement to the Summary l

Report, the District would welcome an additional meeting with the i staff or a conference call. l goS t i j

P;ge - 2 _

April 30,1985 It must also -be -recognized that the schedules submitted in Reference' l for accomplishing modifications to the Control Room are . subject to change due to the additional effort required in implementing the staff's recommendations.

-If you have any questions, please call.

Sincerely, Jay. M.- Pilant Manager, Technical Staff Nuclerr-Power Group JMP::?s30/1 2
