CATAWBA NUCLEAR STATION - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION

Dear Mr. Henderson:

The NRC will perform the baseline heat sink (HS) inspection at your Catawba Nuclear Station from January 14 - 18, 2013. In order to minimize the impact to your on-site resources and to ensure a productive inspection, we have enclosed a request for documents needed for this inspection. These documents have been divided into two groups. The first group (Section A of the enclosure) identifies information to be provided prior to the inspection to facilitate the selection of inspection samples and ensure that the inspectors are adequately prepared. The second group (Section B of the enclosure) identifies additional information needed during the onsite inspection week for the selected inspection samples. 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 onsite portions of the inspection.

We have discussed the schedule for these inspection activities with your staff on November 26, 2012 and understand that our regulatory contact for this inspection will be Mr. Paul Simbrat of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector Joel Rivera-Ortiz at 404-997-4825 (Joel.Rivera-Ortiz@nrc.gov).

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document

K. Henderson 2 Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/
