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 i ssued 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 ins pections 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.

In accordance with 10 CFR 2.390 of the NRC's "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 Record s System (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS

), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
