SUBJECT: BRAIDWOOD STATION - NOTIFICATION OF AN NRC TRIENNIAL HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR INFORMATION INSPECTION REPORT 05000456/2011005; 05000457/2011005 (DRS)
Dear Mr. Pacilio:
On Monday, November 28, 2011, the U. S. Nuclear Regulatory Commission (NRC) will begin the on-site portion of the Triennial Heat Sink Performance Inspection Braidwood Station. This inspection will be performed in accordance with NRC baseline inspection procedure (IP)
71111.07T. 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 17, 2011. By October 20, 2011, the inspector will communicate the initial selected set of approximately 2-3 risk significant heat exchangers. The second group of documents requested is those items 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 14, 2011. 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 Monday, November 28, 2011. 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. The lead inspector for this inspection is Mr. Gerard O'Dwyer. If there are questions about the material requested, or the inspection, please call Mr. O'Dwyer at (630) 829-9624. Please send the information to the following e-mail address Gerard.ODwyer@nrc.gov. A hard-copy with the required information is also an acceptable option. 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. 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. 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.
