UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 March 4, 1986 Docket No. 50-410 Mr. B.
G. Hooten Executive Director of Nuclear Operations Niagara Mohawk Power Corporation 300 Erie Boulevard West
- Syracuse, New York 13202
Dear Mr. Hooten:
Subject:
Water Gap Between Adjacent Fuel Racks in the Spent Fuel Pool for Nine Mile Point, Unit 2 In a letter dated January l, 1986, Niagara Nohawk provided a detailed discussion of a change made in Amendment 23 of the Nine Mile Point, Unit 2 (NMP-2)
FSAR concerning the 3 inch water gap between adjacent fuel racks in the spent fuel pool.
That letter indicated that the gaps between adjacent racks in the north-south direction, as well as the gaps between the racks and the standoffs on portions of the periphery, vary between 2 3/4 inches and 3 1/2 inches.
In addition, your letter of January 9, 1986, indicated that a review of the criticality analysis revealed that the effect of the water gap is so strongly negative that the difference between -the nominal 3 inch and the 2 3/4 to 3 1/2 inch actual gaps is insignificant.
The staff has reviewed your letter of January 9, 1986, and concludes that no change to the conclusion of the SER on the spent fuel pool is needed.
The effect of the small change (minimum spacing of 2.75 inches) in the rack-to-rack spacing is insignificant.
Sincerely, v~M<~
Elinor G. Adensam, Director BWR Project Directorate No.
