EDWIN I. HATCH NUCLEAR PLANT - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION
Dear Mr. Madison:
The NRC will perform the baseline heat sink (HS) inspection at your Edwin I. Hatch Nuclear Plant from May 13 - 17, 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 and understand that our regulatory contact for this inspection will be Sharon Beverly of your organization. Our inspection dates are subject to change based on your updated schedule of outage activities. If there are any questions about this inspection or the material requested, please contact the lead inspector Brendan Collins at (404) 997-4420 (Brendan.Collins@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 Room or from the Publicly Available Records (PARS) component of NRC's document system
