Response to Request for Additional information Regarding the Nine Mile Point Unit 1 Detailed Control Room Design Revie)v 0

Gentlemen:

Niagara Mohawk's letter of February 3, 1995 (NMP1L 0900) informed the Commission that we had evaluated Human Engineering Observations (HEOs) EA-006 (installation of a high pressure coolant injection override switch) and EA-007 (elimination of automatic initiation of containment spray) and determined that no plant modifications were warranted. An informal Request for Additional Information (RAI) was faxed to us on February 22, 1995 and was discussed with Messrs. West and Eckenrode in an April 5, 1995 telephone conference.

During that telephone conference, a request for a written response to selected RAI questions was made. The answers are provided in the Attachment to this letter.

Should you have any questions or wish to discuss this matter further, please contact Mr. W.

David Baker at (315) 349-4245.

Very truly yours, C. D. Terry Vice President - Nuclear Engineering CDT/JTP/kab Enclosure XC: Regional Administrator, Region I Mr. L. B. Marsh, Director, Project Directorate I-l, NRR Mr. G. E.
