SUBJECT:

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

Dear Mr. Mr. Pacilio:

On January 7, 2013, the U. S. Nuclear Regulatory Commission, (NRC) will begin the Temporary Instruction (TI) inspection, Review of Implementation of the Industry Initiative to Control Degradation of Underground Piping and Tanks, (TI 2515-182) at your Braidwood Station Units 1 and 2. This on-site inspection is scheduled to be performed January 7-11, 2013.

In order to minimize the impact to your on-site resources, and to ensure a productive inspection for both sides, we have enclosed a list of documents pertinent to our inspection. The documents that are requested for this inspection include all relevant documents that will allow the inspector(s) to adequately complete Phase II of this inspection. 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 Mr. A. Murtaza, of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector Mr. M. Holmberg at (630) 829-9748.

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. 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.

M. Pacilio 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/
