NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 M5 OCT 11 Docket No.: 50-440 Ms. Susan L. Hiatt OCRE Representative 8275 Munson Road Mentor, Ohio 44060
Dear Ms. Hiatt:
This is in response to your letter dated August 30, 1985, in which you expressed a concern regarding the suggestion made in my letter to the Cleveland Electric Illuminating Company (CEICO) dated August 26, 1985, that CEICO should consider licensing Perry Unit I control room design on a Preliminary Design Analysis or PDA basis, as opposed to CEIC0's intent to license on a Detailed Control Room Design Review or DCRDR basis.
made which I believe summarizes the essence of your concern as follows 1.

Correction of Human Engineering Discrepancies (HEDs) per commitment With respect to the first issue, the actions which must be taken for close-out of the Perry DCRDR are identified in the staff's evaluation report enclosed with my letter to CEICO dated August 26, 1985. Each action involves completion of an activity already well underway. CEICO must negotiate a schedule for completion of those actions if it elects to receive a license on the basis of a PDA.
The staff will assure that safety is a key issue in any such negotiation.
Sofae actions would be required to be completed prior to low power licensing.
Others would be required to be completed prior to full power licensing or prior to start-ur Or the second operating cycle depending upon their safety significan%

Ms. Susan L. Hiatt OCT11 1985 ities do exist.
In cases where a DCRDR activity is to extend beyond licen-sing the staff requires interim activities prior to low power licensing.
Given completion of that interim activity, correction of safety significant HEDs, and commitment to a reasonable schedule for completing the activity, there is frequently little reason to delay licensing.
In the case of Perry, the staff believes that it may be reasonable to continue some DCRDR activi-ties beyond licensing.
If such a schedule is requested and justified by CEICO, completion of some DCRDR activities will be addressed by license con-ditions. The possible deferral of DCRDR completion does not negate the value of the review already completed, nor does it negate CEICO's commitment to correct over 300 HEDs prior to low power licensing. The possible deferral does, however, recognize that some DCRDR activities are iterative and that the final iteration might best be perfonned at a date which follows licensing.
I hope that this response will allay your concerns regarding the Perry control room design review process.
