SUBJECT:
BYRON STATION, UNITS 1 AND 2 INFORMATION REQUEST FOR AN NRC TRIENNIAL PERMANENT MODIFICATIONS, 10 CFR 50.59 (MOD/50.59) BASELINE INSPECTION AND TEMPORARY INSTRUCTION 2515/166, PRESSURIZED WATER REACTOR CONTAINMENT SUMP BLOCKAGE
Dear Mr. Crane:
On January 14, 2008, the NRC will begin a Modifications, 10 CFR 50.59 (MOD/50.59) baseline inspection at the Byron Station, Units 1 and 2. In addition, we intend to complete Temporary Instruction (TI) 2515/166, Pressurized Water Reactor Containment Sump Blockage. This inspection will be performed in accordance with the NRC baseline Inspection Procedures (IP) 71111.02, IP 71111.17 and TI 2515/166. However, please note that in accordance with recent Reactor Oversight Process inspection program realignment results, IP 71111.02 and IP 71111.17 are planned to be combined into a new revised procedure. This procedure is currently under development, but will likely be issued in time for implementation for this inspection. The on-site portions of the inspection will take place on January 14 through January 18, 2008 and January 28 through February 1, 2008.
Experience has shown that these baseline inspections are extremely resource intensive, both for the NRC inspectors and the licensee staff. In order to minimize the inspection impact on the site and to ensure a productive inspection for both parties, we have enclosed a request for documents needed for the inspection. These documents have been divided into four groups. The first group is necessary to ensure that the inspection team is adequately prepared for the inspection. This information should be available to the Regional Office no later than December 10, 2007. The inspection team will review this information and, by December 21, 2007, will request specific items that should be available for review by January 7, 2008, i.e., the second group of documents. The third group of requested documents contains items that the team will review, or need access to, during the inspection and should be available by the first day of the on-site inspection, January 14, 2008. The fourth group lists information necessary to aid the inspection team in tracking issues identified as a result of the inspection. It is requested that this information be provided to the lead inspector as the information is generated during the inspection. 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 on-site portions of the inspection.
The lead inspector for this inspection is Mr. Langstaff. We understand that our contacts with your organization for this inspection are Mr. Perchiazzi and Ms. Hubert, for technical and regulatory areas, respectively. If there are any questions about the inspection or the material
C. Crane requested, please contact the lead inspector at (301) 415-1082 (through December 7, 2007, or at (630) 829-9747 thereafter) or via e-mail at RAL4@nrc.gov.
