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,
/RA: ERIC J. STAMM FOR/
