SUBJECT: NOTIFICATION OF ST. LUCIE PLANT COMPONENT DESIGN BASES
INSPECTION - U.S. NUCLEAR REGULATORY COMMISSION INSPECTION
REPORT 05000335/2016008 AND 05000389/2016008
Dear Mr. Nazar:
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 St. Lucie Plant
during the weeks of February 8 - 12, and February 29 - March 4, 2016. Mr. Eric Stamm, a
Senior Reactor Inspector from the NRCs Region II office, will lead the inspection team. This
inspection will be a pilot to test the feasibility of conducting a two-week CDBI. The inspection
will be conducted in accordance with Inspection Procedure 71111.21T, Component Design
Bases Inspection (Teams), which will be issued at a future date. The inspection procedure is in
the NRCs Agency Documents Access and Management System (ADAMS) as #ML15154A586.
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 October 5, 2015, with Mr. Eric Katzman, we confirmed
arrangements for an information-gathering site visit and the two-week onsite inspection. The
schedule is as follows:
Information-gathering visit: Week of January 11 - 15, 2016
Onsite weeks: February 8 - 12, and February 29 - March 4, 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. John Hanna, 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.

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 Thursday, December 31,
2015. Additional documents may be requested during 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 need to be
available to the team in the Region II office prior to the inspection teams preparation week of
February 1, 2016. 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/
