S. Nuclear Regulatory Commission 50-305 Washington, DC 20555-0001 License No.: DPR-43 DOMINION ENERGY KEWAUNEE, INC.
KEWAUNEE POWER STATION INDEPENDENT SPENT FUEL STORAGE INSTALLATION CASK REGISTRATION FOR SPENT FUEL STORAGE Pursuant to 10 CFR 72.212, "Conditions of general license issued under §72.210,"
paragraph (b)(1)(ii), Dominion Energy Kewaunee, Inc. (DEK) hereby provides the Nuclear Regulatory Commission (NRC) notification regarding the registration of spent fuel storage casks approved under NRC Certificate of Compliance No. 1004.
Licensee Name: Dominion Energy Kewaunee, Inc.
Licensee Address: N490 Highway 42 Kewaunee, WI 54216 Reactor License No.: DPR-43 Reactor Docket No.: 50-305 Cask Certificate No.: 1004 Cask Model No.: Standardized NUHOMS-32PT Canister Cask Identification Nos.: KPS32PT-S100-A-HZ005 Initial Use: 6/10/2010 KPS32 PT-S 100-A-HZ004 Initial Use: 6/17/2010 Licensee Contact Name/Title: John Helfenberger, Reactor Engineer The above named casks are in use under Amendment 9 of Certificate of Compliance No. 1004.
In addition, pursuant to the General Requirements and Conditions of the Technical Specifications for Certificate of Compliance No. 1004, Amendment 9, Paragraph 1.1.7, "Special Requirements for First System in Place," a summary of the thermal performance of the highest heat load Standardized NUHOMS-32PT Dry Shielded Canister (DSC) placed in service at the Kewaunee Power Station independent spent fuel storage installation is provided. The decay heat load for canister KPS32PT-S100-A-HZ005 is greater than those canisters previously loaded. KPS32PT-S100-A-HZ005 was loaded with Unit 1 spent fuel and stored in a NUHOMS Model 102 Horizontal Storage Module (HSM). The calculated thermal loading for this DSC is approximately 16.6 kW. The inlet and outlet air temperatures for the HSM were measured consistent
Serial No.10-385 Page 2 of 3 with the method provided in Certificate No. 1004 Technical Specification 1.2.8. Upon obtaining equilibrium conditions, the measured inlet air temperature was 71.4 degrees F and measured outlet air temperature was 129.9 degrees F, corresponding to a temperature difference of 58.5 degrees F. This temperature difference is within the thermal performance temperature differential of 70 degrees F expected for a Model 102 HSM containing a DSC with a thermal loading of 16.6 kW at the given ambient conditions.
Also, since the heat load for canister KPS32PT-S100-A-HZ004 is greater than previously loaded canisters and was loaded after canister KPS32PT-S100-A-HZ005, a summary of the thermal performance is provided. KPS32PT-S100-A-HZ004 was loaded with Unit 1 spent fuel and stored in a NUHOMS Model 102 Horizontal Storage Module (HSM). The calculated thermal loading for this DSC is approximately 16.7 kW.
The inlet and outlet air temperatures for the HSM were measured consistent with the method provided in Certificate No. 1004 Technical Specification 1.2.8. Upon obtaining equilibrium conditions, the measured inlet air temperature was 71.4 degrees F and measured outlet air temperature was 134.9 degrees F, corresponding to a temperature difference of 63.5 degrees F. This temperature difference is within the thermal performance temperature differential of 70 degrees F expected for a Model 102 HSM containing a DSC with a thermal loading of 16.7 kW at the given ambient conditions.
Equilibrium conditions were reached for both canisters by June 30, 2010, based on HSM concrete temperatures. However, DEK staff discovered that the temporary temperature probes used to monitor outlet air temperatures on canister KPS32PT-S100-A-HZ005 had been inserted too deeply into the air outlet vent of its associated HSM. This resulted in the temperature probes measuring temperatures that were higher than the representative value of outlet air temperature (which produced an erroneous temperature differential in excess of the 70 degrees F expected for this HSM). Once this condition was identified, the probes were repositioned to accurately measure the representative value of outlet air temperature. DEK continues to evaluate the circumstances that led to this condition and appropriate corrective actions.

Jack Gadzala at 920-388-8604.
