UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 June 23, 2010 Mr. George H. Gellrich, Vice President Calvert Cliffs Nuclear Power Plant, LLC Calvert Cliffs Nuclear Power Plant 1650 Calvert Cliffs Parkway Lusby, MD 20657-4702

SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION RE: PROPOSED TRANSITION FROM WESTINGHOUSE TO AREVA NUCLEAR FUEL - CALVERT CLIFFS NUCLEAR POWER PLANT, UNIT NOS. 1 AND 2 - (TAC NOS. ME2831 AND ME2832)

Dear Mr. Gellrich:

By letter dated November 23,2009, Calvert Cliffs Nuclear Power Plant, LLC requested a license amendment for the Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 and 2. The amendment would modify the Calvert Cliffs licensing basis and the Technical Specifications to allow the use of AREVA Advanced CE-14 High Thermal Performance fuel in the Calvert Cliffs reactors.

Calvert Cliffs currently uses Westinghouse Turbo 14x14 fuel assemblies in both units.

The NRC staff has reviewed the information provided and has determined that additional information is needed to complete its review. Enclosed is the staff's request for additional information (RAI). As discussed with your staff, we understand that you intend to respond to this RAI within 30 days of the date of this letter.

Please contact me at 301-415-1364 if you have any questions.

Sincerely,

~'-Jf~

REQUEST FOR ADDITIONAL INFORMATION CALVERT CLIFFS NUCLEAR POWER PLANT, UNIT NOS. 1 AND 2 TRANSITION TO AREVA NUCLEAR FUEL

1. A modification to the licensing basis fuel type can have the potential to change the core isotopic distribution assumed in post accident conditions. Based upon this, please provide additional information regarding the effect the proposed fuel type change has on the current radiological consequence design basis analyses. Please provide any changes to the parameters, assumptions, or methodologies in the radiological design-basis accident (DBA) analyses as a result of the proposed fuel type change and justification for those changes. If there are changes to the radiological DBA analyses, please provide the resulting change to the calculated radiological consequence of the DBAs.
