NUCLEAR REGULATORY COMMISSION

REGION IV

1600 E. LAMAR BLVD

ARLINGTON, TX 76011-4511

March 1, 2016

Chief Executive Officer

SUBJECT: COLUMBIA GENERATING STATION - NOTIFICATION OF NRC DESIGN

BASES INSPECTION (05000397/2016007) AND INITIAL REQUEST FOR

INFORMATION

Dear Mr. Reddemann:

On June 6, 2016, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial baseline

Design Bases Inspection at the Columbia Generating Station. A 7-person team will perform this

inspection using the NRC Inspection Procedure 71111, Attachment 21M 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 two weeks of onsite inspection by the team. The inspection will consist of

five NRC inspectors and two contractors, of which six will focus on engineering and one on

operations. The current inspection schedule is as follows:

Onsite Information Gathering Visit: March 28-31, 2016

In-Office Preparation Week: May 23-27, 2016

Onsite Weeks: June 6-10, 2016, and June 20-24, 2016

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. During the onsite weeks, several days 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 interviews with

engineering managers, engineers, and probabilistic safety assessment staff throughout the

inspection

M.E. Reddmann -2-

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 April 27, 2016. 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 is 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 both onsite weeks for specific documents needed to complete the review of the

components selected. 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 Mr. Ronald A. Kopriva. We understand that our

licensing engineer contact for this inspection is Ms. Tracey Parmelee. If there are any questions

about the inspection or the requested materials, please contact the lead inspector by telephone

at 817-200-1104 or by e-mail at Ron.Kopriva@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.

M.E. Reddmann -3-

In accordance with 10 CFR 2.390 of the NRCs 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 NRCs document system (ADAMS).

ADAMS is accessible from the NRC Web site at http://www.nrc.gov/readinq-rm/adams.html

(the Public Electronic Reading Room).

Sincerely,
