SUBJECT: NOTIFICATION OF BRUNSWICK STEAM ELECTRIC PLANT COMPONENT

DESIGN BASES INSPECTION - U.S. NUCLEAR REGULATORY COMMISSION

INSPECTION REPORT 05000325/2016007 AND 05000324/2016007

Dear Mr. Gideon:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

Region II staff will conduct a component design bases inspection (CDBI) at your Brunswick

Steam Electric Plant, Units 1 and 2, during the weeks of November 14, November 28, and

December 12, 2016. Mr. Eric Stamm, a Senior Reactor Inspector from the NRCs Region II

office, will lead the inspection team. The inspection will be conducted in accordance with

Inspection Procedure 71111.21, Component Design Bases Inspection, dated November 29,

2013.

The inspection will evaluate the capability of risk-significant/low-margin components to function

as designed and to support proper system operation. The inspection will also include a review

of selected operator actions, operating experience, and modifications.

During a telephone conversation on July 11, 2016, with Mr. Lee Grzeck, we confirmed

arrangements for an information-gathering site visit and the three-week onsite inspection. The

schedule is as follows:

Information-gathering visit: Week of October 17, 2016

Onsite weeks: Weeks of November 14-18, November 28-December 2, and

December 12-16, 2016

The purpose of the information-gathering visit is to meet with members of your staff to identify

risk-significant components and operator actions. Information and documentation needed to

support the inspection will also be identified. Mr. Rudolph Bernhard, a Region II Senior Risk

Analyst, will support Mr. Stamm during the information-gathering visit to review probabilistic risk

assessment data and identify risk-significant components to be examined during the inspection.

Additionally, during the onsite weeks, time will be needed on the plant-referenced simulator in

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

The enclosure lists documents that will be needed prior to the information-gathering visit.

Please provide the referenced information to the Region II Office by Friday, October 7, 2016.

Additional documents will be requested following the information-gathering visit. The inspectors

will try to minimize your administrative burden by specifically identifying only those documents

required for inspection preparation. The additional information will be needed in the Region II

office by Friday, October 28, 2016, to support the inspection teams preparation week. During

the information-gathering trip, Mr. Stamm will also discuss the following inspection support

administrative details: (1) availability of knowledgeable plant engineering and licensing

personnel to serve as points of contact during the inspection; (2) method of tracking inspector

requests during the inspection; (3) licensee computer access; (4) working space; (5)

arrangements for site access; and (6) other applicable information.

In accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections,

Exemptions, Requests for Withholding, 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) component of NRC's

Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible

from the NRC website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic

Reading Room).

Thank you for your cooperation in this matter. If you have any questions, regarding the

information requested or the inspection, please contact Mr. Stamm at 404-997-4575 or contact

me at 404-997-4607.

Sincerely,
