SUBJECT:
NOTIFICATION OF EDWIN I. HATCH NUCLEAR PLANT - NRC
COMPONENT DESIGN BASES INSPECTION - INSPECTION REPORT
05000321/2012008 AND 05000366/2012008
Dear Mr. Madison:
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 at your Edwin I. Hatch Nuclear
Plant during the weeks of June 25 - June 29, July 9 - July 13, and July 23 - July 27, 2012.
Patrick Higgins, 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 December 6,
2010.
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 March 12, 2012, Mr. Higgins confirmed with Mr. Tipps 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 June 4 - 8, 2012
Onsite weeks: June 25 - June 29, July 9 - July 13, and July 23 - July 27, 2012
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 accompany Mr. Higgins during the information-gathering visit to review probabilistic
risk assessment data and identify risk significant components that 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 May 21, 2012. Contact Mr.
Higgins with any questions concerning the requested information. The inspectors will try to
SNC, Inc.

minimize your administrative burden by specifically identifying only those documents required
for inspection preparation.
Additional documents will be requested during the information-gathering visit. The additional
information will need to be available to the team in the Region II office prior to the inspection
teams preparation week of June 18, 2012. Mr. Higgins will also discuss the following inspection
support administrative details: availability of knowledgeable plant engineering and licensing
personnel to serve as points of contact during the inspection; method of tracking inspector
requests during the inspection; licensee computer access; working space; arrangements for site
access; and 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 document system
(ADAMS). ADAMS is accessible from the NRC Web site 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. Higgins at 404-997-4615 or me at
404-997-4530.
Sincerely,
/RA/
