SUBJECT:

DUANE ARNOLD ENERGY CENTER REQUEST FOR INFORMATION FOR AN NRC TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION (CDBI) INSPECTION REPORT 05000 331/201400 8

Dear Mr. Anderson:

On Ma y 19, 201 4 , the U. S. Nuclear Regulatory Commission (NRC) will begin a triennial baseline Component Design Bases Inspection (CDBI) at Duane Arnold Energy Center

. A team of six inspectors will perform this 3-week inspection. This inspection will be performed in accordance with NRC Baseline Inspection Procedure (IP) 71111.21.

The CDBI focuses on the design, maintenance, and operation of risk

-significant components associated with one or more accident scenario. The components to be reviewed during this baseline inspection will be identified during the in-office preparation week that occurs prior to th e first on-site inspection week. In addition, operating experience issues, associated with the component samples, will also be selected for review. The inspection team may request scenarios to be performed on the simulator. This request would require support from you r simulator staff to validate scenarios, simulator time, and a crew to perform the actions which would most likely occur during the second on

-site week. The team will work closely with your staff early on during the inspection process to ensure this activity can be accomplished with minimal impact.

The inspection will include three weeks on-site. The inspection team will consist of six NRC inspectors, of which five will focus on engineering/maintenance and one on operations. The current inspection schedule is as follows:

On-site weeks:

Ma y 19, 201 4; June 02, 201 4; and June 16, 201 4 The team will be preparing for the inspection, mainly during the week of May 1 2, 201 4, as discussed in the attached enclosure.

R. Anderson Experience with previous baseline design inspections of similar depth and length has shown that th is type of inspection is 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 for both parties, we have enclosed a request for information needed for the inspection.

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 on

-site portions of the inspection. Insofar as possible, this information should be provided electronically to the lead inspector. The information request has been divided into three groups:

The first group lists information necessary for our initial inspection scoping activities. This information should be provided to the lead inspector no later than March 31, 201 4. By April 18, 2014, the lead inspector will communicate the initial selected set of approximately 20 components.

The second group of documents requested is those items needed to support our in

-office preparation activities. This set of documents, including the calculations associated with the initial selected components, should be provided to the lead inspector at the Regional Office no later than May 7, 2014. During the in

-office preparation activities, the team may identify additional information needed to support the inspection.

The last group includes the additional information above

, as well as plant specific reference material. This information should be available to the team onsite on May 19, 2014. It is also requested that corrective action documents and/or questions developed during the inspection be provided to the lead inspector as the documents are generated.

The lead inspector for this inspection is Benny Jose. We understand that our licensing contact for this inspection is Robert Murrell of your organization. If there are any questions about the inspection or the material requested in the enclosure, please contact the lead inspector at (630) 829-97 5 6 or via e-mail at benny.jose@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.

R. Anderson In accordance with Title 10, Code of Federal Regulations (CFR) "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 System (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading

-rm/adams.html (the Public Electronic Reading Room).
