Please consider this e-mail as the official Request for Information (RFI) for the Upcoming NRC Triennial Heat Sink Performance Inspection (05000266/2016002; 05000301/2016002). Please confirm via e-mail that you have received this RFI. The inspection will be performed in accordance with inspection procedure 71111.07.The inspectors will be on site from June 6, 2016 through June 10, 2016.The assigned inspectors are Lionel Rodriguez and myself (Lead).The requested documents have been divided into three groups: The first group lists information necessary for our initial inspection scoping activities. This informationshould be available to the lead inspector no later than Monday, May 2, 2016. By Tuesday May 10,2016, I will communicate the initial selected set of approximately 2-3 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 theRegional Office no later than Wednesday, May 25, 2016. This information should be separated for eachselected component, especially if provided electronically (e.g., folder with component name thatincludes calculations, condition reports, maintenance history, etc.). During the in-office preparationactivities, the inspectors 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, Monday June 6, 2016. It is alsorequested that corrective action documents and/or questions developed during the inspection beprovided 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 on-site inspection.
