SUBJECT: ARKANSAS NUCLEAR ONE - NOTIFICATION OF INSPECTION (NRC

INSPECTION REPORT 050000368/2009004) AND REQUEST FOR

INFORMATION

Dear Mr. Walsh:

From September 3 through September 17, 2009, reactor inspectors from the U.S. Nuclear

Regulatory Commissions (NRC) Region IV office will perform the baseline inservice inspection

at Arkansas Nuclear One, Unit 2, using NRC Inspection Procedure 71111.08, "Inservice

Inspection Activities," and TI 2515/172, "Reactor Coolant System Dissimilar Metal Butt Welds."

Experience has shown that this inspection is a resource intensive inspection both for the NRC

inspectors and your staff. In order to minimize the impact to your onsite resources and to

ensure a productive inspection, we have enclosed a request for documents needed for this

inspection. These documents have been divided into two groups. The first group (Section A of

the enclosure) identified information to be provided prior to the inspection to ensure that the

inspectors are adequately prepared. The second group (Section B of the enclosure) identifies

the information the inspectors 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 Mr. Van Buskirk of your licensing

organization. Our inspection dates are subject to change based on your updated schedule of

outage activities. If there are any questions about this inspection or the material requested,

please contact the lead inspector Michael Bloodgood at (817) 276-6544

(Michael.Bloodgood@nrc.gov) or Jeffrey Josey at (479) 968-3290 (Jeffrey.Josey@nrc.gov).

In accordance with 10 CFR 2.390 of the NRCs "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 (PARS) component of NRCs document

system (ADAMS). ADAMS is accessible from the NRC web site at http://www.nrc.gov/reading-

rm/adams.html (the Public Electronic Reading Room).
