UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE ROAD, SUITE 210 LISLE, IL 60532-4352 February 3, 2011 Mr. Michael J. Pacilio Senior Vice President, Exelon Generation Company, LLC President and Chief Nuclear Officer (CNO), Exelon Nuclear 4300 Winfield Road Warrenville IL 60555

SUBJECT:

BYRON STATION UNITS 1 AND 2 - NOTIFICATION OF NRC INSPECTION AND REQUEST FOR INFORMATION

Dear Mr. Pacilio:

On April 25, 2011, the NRC will begin inspection of refueling and other outage activities (NRC Inspection Procedure 71111.20). This inspection will utilize NRC Operating Experience Smart Sample: (OpESS) FY2007-03, Revision 2, Crane and Heavy Lift Inspection, Supplemental Guidance for IP 71111.20, issued September 12, 2008. This inspection will focus on the impact of load handling activities on the reactor core and its cooling and plant support systems.

Specifically, this inspection will review the upgrade of the containment polar cranes to single-failure-proof equivalency using guidelines developed by the Nuclear Energy Institute (NEI) and contained in NEI 08-05, Industry Initiative on Control of Heavy Loads, Revision 0, and NRC Regulatory Issue Summary 2008-28, Endorsement of Nuclear Energy Institute Guidance for Reactor Vessel Head Heavy Load Lifts, dated December 1, 2008. The on-site inspection is scheduled to take place on April 25 through April 29, 2011, and May 23 through May 27, 2011.

Experience has shown that inspection of these activities is resource intensive both for the NRC inspector and licensee staff. In order to minimize the inspection impact to the site and to ensure a productive inspection for both parties, we have enclosed a request for information needed for the inspection. This information should be available in Region III by April 11, 2011, (preparation week). It is important that all of these documents are up to date and complete in order to minimize the number of additional documents requested during the preparation and/or the on-site portions of the inspection.

We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Ms. T. Hulbert, of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector Mr. J. Neurauter at (630) 829-9828.

This letter does not contain new or amended information collection requirements subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection requirements were approved by the Office of Management and Budget, control number 3150-0011.

M. Pacilio The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget control number.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/
