SUBJECT: ARKANSAS NUCLEAR ONE, UNIT 2 - NOTIFICATION OF INSPECTION (NRC

INSPECTION REPORT 050-368/2011002) AND REQUEST FOR

INFORMATION

Dear Mr. Berryman:

From February 22 to March 5, 2011, reactor inspectors from the 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. 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), due by February 1, 2011, identifies 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 Ms. Stephanie Pyle 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 Jim Melfi, lead inspector, at (817) 276-6523 (jim.melfi@nrc.gov) or Dustin

Reinert at (817) 860-8244 (dustin.reinert@nrc.gov).

This letter does not contain new or amended information collection requirements subject to the

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection

requirements were approved by the Office of Management and Budget, Control

Number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to

respond to, a request for information or an information collection requirement unless the

requesting document displays a currently valid Office of Management and Budget control

number.

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-
