SUBJECT: BRAIDWOOD STATION, UNITS 1 AND 2NOTIFICATION OF AN NRC TRIENNIAL HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR INFORMATION; INSPECTION REPORT 05000456/2017004; 05000457/2017004

Dear Mr. Hanson:

On Monday, November 16, 2017, the U.S. Nuclear Regulatory Commission (NRC) will begin the onsite portion of the Triennial Heat Sink Performance Inspection at your Braidwood Station, Units 1 and 2. This inspection will be performed in accordance with NRC Baseline Inspection Procedure 71111.07. In order to minimize the impact that the inspection has on the site and to ensure a productive inspection, we have enclosed a request for documents needed for the inspection. The documents have been divided into three groups. The first group lists information necessary for our initial inspection scoping activities. This information should be available to the lead inspector no later than October 9, 2017. By October 11, 2017, the inspector will communicate the selected set of approximately 23 risk-significant heat exchangers. The second group is needed to support our in-office preparation activities. This set of documents, including the calculations associated with the selected heat exchangers, should be available at the Regional Office no later than November 2, 2017. This information should be separated for each selected component, especially if provided electronically (e.g., folder with component name that includes calculations, condition reports, maintenance history, etc.). During the in-office preparation activities, the inspector may identify additional information needed to support the inspection. The last group includes the additional information above as well as plant specific reference material. This information should be available onsite to the inspector on November 13, 2017. It is also requested that corrective action documents and/or questions developed during the inspection be provided to the inspector as the documents are generated. All requested documents are to be for the time period from the onsite inspection period back to the documents that were provided in response to the previous Heat Sink Performance Inspection. If no activities were accomplished in that time period, then the request applies to the last applicable document in the previous time period. It is important that these documents be as complete as possible, in order to minimize the number of documents requested during the preparation week or during the onsite inspection. The lead inspector for this inspection is We understand that our licensing contact for this inspection is Richard Schliessmann of your organization. If there are any questions about the inspection or the material requested in the enclosure, please contact the lead inspector at 630-829-9624 or via e-mail at Gerard.ODwyer@nrc.gov. 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. This letter and its enclosure will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR
