SUBJECT: RIVER BEND STATION- NOTIFICATION OF INSPECTION (INSPECTION

REPORT 05000458/2011005) AND REQUEST FOR INFORMATION

Dear Mr. Olson:

On November 14, 2011, the NRC 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 River Bend Station. This inspection 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 on-site 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 October 31, 2011. Upon review

of these documents, the inspectors will select additional documentation for review upon

arrival. By November 3, 2011, the inspector will communicate the initial selected samples.

• The second group of documents requested is needed to support our on-site inspection

activities. This set of documents should be available to the inspector on November 14, 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 Danny Williamson of your licensing

organization. If there are any questions about this inspection or the material requested, please

contact the inspector, Matt Young, at 817-276-6545 or by email at matt.young@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

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)

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 Matt Young, 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 then request from

your staff additional documents needed during the on-site 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 on-site inspection. If you have any questions

regarding this information request, please call the inspector as soon as possible.
