SUBJECT: CALLAWAY PLANT - INFORMATION REQUEST FOR NRC TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION NRC INSPECTION REPORT 05000483/2014007

Dear Mr. Heflin:

On April 14, 2014, the NRC will begin a triennial baseline Component Design Bases Inspection at the Callaway Plant. 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 3-weeks of onsite inspection by the team. The inspection will consist of seven NRC inspectors, of which six will focus on engineering and one on operations. The current inspection schedule is as follows:

Onsite information gathering visit: Week of March 24, 2014 Onsite weeks: First On-Site Week - April 14-18, 2014 Second On-Site Week - April 28 - May 2, 2014 Third On-Site Week - May 12-16, 2014 The purpose of the information gathering visit is to meet with members of your staff to identify potential risk-significant components and operator actions. The lead inspector will also request a tour of the plant with members of your operations staff and probabilistic safety assessment staff. Additional information and documentation needed to support the inspection will be identified, including interviews with engineering managers, engineers, and probabilistic safety assessment staff. Our experience with these inspections has shown 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 March 17, 2014. Insofar as possible, this information should be provided electronically to the lead inspector. 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 when onsite and after the inspection samples are selected. 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. It is important that all of these documents are up to date and completed 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 Mr. Ronald Kopriva. We understand that our licensing engineer contact for this inspection is Mr. Steve Petzel. If there are any questions about the inspection or the requested materials, please contact the lead inspector at (817) 200-1104 or via e-mail at Ron.Kopriva@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 Docket: 50-483 License: NPF-30
