SUBJECT: RIVER BEND STATION - NOTIFICATION OF NRC COMPONENT DESIGN BASES INSPECTION (05000458/2014007) AND INITIAL REQUEST FOR INFORMATION

Dear Mr. Olson:

On July 8, 2014, the NRC will begin a triennial baseline Component Design Bases Inspection at the River Bend Station. A seven person team will perform this inspection using NRC Inspection Procedure 71111.21, "Component Design Bases Inspection." The inspection focuses on components and operator actions that have high risk and low design margins. The samples reviewed during this inspection will be identified during an information gathering visit and during the subsequent in-office preparation week. In addition, a number of operating experience issues will also be selected for review. The inspection will include an information gathering site visit by the team leader and a senior reactor analyst, and three weeks of onsite inspection by the team. The inspection team will consist of seven members; a team leader, four NRC inspectors, and two contractors. Five of the members will focus on engineering and one on operations. The current inspection schedule is as follows: Onsite Information Gathering Visit: July 8, 2014 Preparation Week: July 14-18, 2014 Onsite Weeks: July 21-25, 2014; August 4-8, 2014; and August 18-22, 2014 The purpose of the information gathering visit is to meet with members of your staff to identify potential risk-significant systems, components, and operator actions. The team leader will also request a tour of the plant with members of your operations staff and probabilistic safety assessment staff. During the onsite weeks, several days of time will be needed on the plant-

referenced simulator in order to facilitate the development of operator action-based scenarios.

Additional information and documentation needed to support the inspection will be identified during the inspection, including interviews with engineering managers, engineers, and probabilistic safety assessment staff. Our experience with these inspections has shown that they are extremely resource intensive, both for the NRC inspectors and the licensee staff. In order to minimize the inspection impact on the site and to ensure a productive inspection, we have enclosed a request for information needed for the inspection. The request has been divided into three groups. The first group lists information necessary for the information gathering visit and for general preparation. This information should be available to the regional office no later than June 23, 2014. Insofar as possible, this information should be provided electronically to the team leader. Since the inspection will be concentrated on high risk/low margin components, calculations associated with your list of high risk components should be available to review during the information gathering visit to assist in our selection of components based on available design margin. The second group of documents requested are those items that the team will need access to during the preparation week in order to finalize the samples to be inspected. The third group lists information necessary to aid the inspection team in tracking issues identified as a result of the inspection. It is requested that this information be provided to the lead inspector as the information is generated during the inspection. Additional requests by inspectors will be made throughout all three onsite weeks for specific documents needed to complete the review of that component/selection. 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. In order to facilitate the inspection, we request that a contact individual be assigned to each inspector to ensure information requests, questions, and concerns are addressed in a timely manner. The lead inspector for this inspection is Gerond A. George. We understand that our licensing engineer contact for this inspection is Kristi Huffstatler. If there are any questions about the inspection or the requested materials, please contact the lead inspector by telephone at 817-200-1562 or by e-mail at Gerond.George@nrc.gov. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be made 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.html (the Public Electronic Reading Room).

Sincerely,/RA/ Thomas R. Farnholtz, Chief Engineering Branch 1 Division of Reactor Safety
