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
