SUBJECT:

BYRON STATION, UNIT 2 - NOTIFICATION OF NRC INSPECTION AND REQUEST FOR INFORMATION

Dear Mr. Pardee:

On October 6, 2008, the NRC will begin the baseline inservice inspection (NRC Inspection Procedure PI 71111.08) at the Byron Station, Unit 2. This on-site inspection is scheduled to be performed October 6, 2008 through October 23, 2008.

Experience has shown that this inspection is resource intensive both for the NRC inspector and your staff. In order to minimize the impact to your on-site resources, and to ensure a productive inspection for both sides, we have enclosed a request for documents needed for this inspection.

These documents have been divided into two groups. The first group identifies information necessary to ensure that the inspector is adequately prepared. The second group identifies the information the inspector will need upon arrival at the site. 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 onsite portions of the inspection.

We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Ms. T. Hulbert, of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector Mr. D. Jones at (630) 829-9622.

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 Records System (PARS) component of NRC's

C. Pardee 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).

INSERVICE INSPECTION DOCUMENT REQUEST Inspection Dates: October 6, 2008 - October 23, 2008 Inspection Procedures: IP 71111.08, Inservice Inspection Inspectors: Don Jones (630) 829-9622, donald.jones@nrc.gov I. Information Requested for the In-Office Preparation Week The following information (electronic copy CD ROM if possible) is requested by September 17, 2008, to facilitate the selection of specific items that will be reviewed during the on-site inspection week. The inspector will select specific items from the information requested below and request a list of additional documents needed on-site to your staff. We request that the specific items selected from the lists be available and ready for review on the first day of inspection. If you have any questions regarding this information, please call the inspector as soon as possible.

1. A detailed schedule and description of:

a. non-destructive examinations (NDEs) planned for Class 1 and 2 systems and containment, performed as part of your ASME Code ISI Program (include edition and addenda of Code committed to), and NDE examinations planned for other systems performed as part of a Risk Informed (RI)-ISI Program, or other augmented inspection programs commitments as part of an industry initiative such as Alloy 600 weld inspections (MRP-139), during the scheduled inspection weeks, including the weld identification number, description of weld (component name), category, class, type of exam and procedure number, and date of exam;

b. reactor vessel upper head examinations pursuant to NRC Order 03-009; and

c. steam generator (SG) tube inspection and repair activities for the upcoming outage; and welding on Code Class 1, 2 or 3 components.

2. A copy of the NDE procedures and welding procedures used to perform the activities identified in A.1 (including NDE calibration and flaw characterization/sizing procedures and Welding Procedure Qualification Records). For ultrasonic examination procedures qualified in accordance with Appendix VIII, of Section XI of the ASME Code, provide documentation supporting the procedure qualification (e.g., the EPRI performance demonstration qualification summary sheets).

3. A copy of ASME Section XI, Code Relief Requests applicable to the examinations identified in A(1).
