SUBJECT: NOTIFICATION OF OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3
COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION REPORT
05000269/2014007, 05000270/2014007, 05000287/2014007
Dear Mr. Batson:
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 Oconee
Nuclear Station, Units 1, 2, and 3 during the weeks of February 10 - 14, March 3 - 7, and
March 17 - 21, 2014. Jason Eargle, a Senior Reactor Inspector from the NRCs Region II
Office, will lead the inspection team. This inspection will be conducted in accordance with the
baseline inspection procedure, Procedure 71111.21, Component Design Bases Inspection,
issued August 14, 2012.
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 2, 2013, Mr. Eargle confirmed with Mr. Bob Meixell
and Ms. Judy Smith of your staff, arrangements for an information-gathering site visit and the
three-week onsite inspection. The schedule is as follows:
- Information-gathering visit: Week of January 13-17, 2014
- Onsite weeks: February 10 - 14, March 3 - 7, and March 17 - 21, 2014
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. Rudy Bernhard, a Region II Senior Reactor
Analyst, will support Mr. Eargle during the information-gathering visit to review probabilistic risk
assessment data and identify risk-significant components, which will 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 December 13, 2013.
S. Batson 2
Additional documents will 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 3, 2014.
Mr. Eargle 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 10 CFR 2.390 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. Eargle at 404-997-4632 or contact
me at 404-997-4530.
Sincerely,
