Baseline Data for the Metamic Neutron Poison Coupons Cooper Nuclear Station, Docket No. 50-298, DPR-46

==Reference:==
Letter from Stewart B. Minahan, Nebraska Public Power District, to U.S. Nuclear Regulatory Commission, dated April 17, 2007, 

==Subject:==
 "Response to Request for Additional Information Regarding License Amendment Request for Onsite Spent Fuel Storage Expansion" (NLS2007012)

==Dear Sir or Madam:==

The purpose of this letter is for the Nebraska Public Power District (NPPD) to provide to the Nuclear Regulatory Commission (NRC) the baseline data obtained from unirradiated samples of the Metamic neutron poison used in the new spent fuel racks to be installed at the Cooper Nuclear Station (CNS). The baseline data is provided in Attaclhunent 1.
NPPD committed to submit this data in the Reference letter. The Reference letter was submitted in support of a license amendment request to increase the capacity of the spent fuel storage pool at CNS. The NRC approved the request and issued Amendment No. 227, dated September 6, 2007.
Should you have any questions regarding this matter, please contact me at (402) 825-2904.
Sincerely, David Van Der Kamp Acting Licensing Manager

NLS2007070 Page 2 of 12 The Metamic Coupon Sampling Program at Cooper Nuclear Station consists of ten coupons of the Metamic neutron poison material incorporated into the spent fuel rack supplied by Holtec International, Inc. These ten coupons will be hung on a coupon tree and placed into one of the cells of the rack.
The following table documents the baseline data of the ten coupons prior to being irradiated.
Drawings depicting each of the ten coupons with specific dimensions noted are attached.
