SUBJECT: ARKANSAS NUCLEAR ONE - NOTIFICATION OF INSPECTION (INSPECTION
REPORT 05000313/2011004 AND 05000368/2011004) AND REQUEST FOR
INFORMATION
Dear Mr. Schwarz:
On August 15, 2011, inspectors from the U.S. Nuclear Regulatory Commissions (NRC) Region
IV office will begin the on-site portion of the Gas Accumulation Management in Emergency Core
Cooling, Decay Heat Removal, and Containment Spray Systems Temporary Instruction at your
Arkansas Nuclear One facility. These inspections will be performed in accordance with NRC
Temporary Instruction (TI) 2515/177.
Experience has shown that this inspection is resource intensive 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.
The documents have been divided into two groups.
- The first group lists information necessary for our initial inspection scoping and in-office
preparation activities. This information should be separated by information request number,
especially if provided electronically (e.g., folder with the information request number). This
information should be available to the inspector no later than August 1, 2011. Upon review of
these documents, the inspectors will select additional documentation for review upon arrival.
By August 5, 2011, the inspector will communicate the initial selected samples.
- The second group of documents requested is needed to support our onsite inspection
activities. This set of documents should be available to the inspector on August 15, 2011. It
is also requested that corrective action documents and responses to questions developed
during the inspection be provided to the inspector as the documents are generated.
We have discussed the schedule for these inspection activities with your staff and understand
that our regulatory contact for this inspection will be Bob Clark of your licensing organization. If
there are any questions about this inspection or the material requested, please contact the
inspector, Rayomand Kumana, at 817-860-8185 or by email at rayomand.kumana@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 Code of Federal Regulations, Title 10, Part 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 (PARS)
component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web
site at http://www.nrc.gov/reading-rm/adams (the Public Electronic Reading Room).

The following information should be sent to the Region IV office in hard copy or electronic
format (ims.certrec.com or compact disc, preferred), in care of Rayomand Kumana to facilitate
the selection of specific items that will be reviewed during the onsite inspection week. The
inspector will select specific items from the information requested below and then request from
your staff additional documents needed during the onsite inspection weeks. Also, we request
that you categorize the documents in your response with the numbered list below. Please
provide requested documentation electronically if possible. If requested documents are large
and only hard copy formats are available, please inform the inspector(s), and provide subject
documentation during the first day of the onsite inspection. If you have any questions regarding
this information request, please call the inspector as soon as possible.
