SUBJECT: GRAND GULF NUCLEAR STATION - NOTIFICATION OF NRC TRIENNIAL HEAT
SINK PERFORMANCE INSPECTION (05000416/2016003) AND REQUEST FOR
INFORMATION
Dear Mr. Fallacara:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff
will conduct a triennial heat sink performance inspection at your Grand Gulf Nuclear Station
from September 19, 2016 to September 23, 2016. The inspection will consist of one reactor
inspector from the NRCs Region IV office for one week. The inspection will be conducted in
accordance with NRC Inspection Procedure 71111.07, "Heat Sink Performance."
Experience has shown that this inspection is resource intensive both for the NRC inspectors
and your staff. In order to minimize the impact to your on-site resources and to ensure a
productive inspection, we have enclosed a request for documents needed for this inspection.
Please note that the documents are requested to be provided by September 12, 2016. We
request that during the on-site inspection week, you ensure that copies of analyses, evaluations,
or documentation regarding the implementation and maintenance of your heat exchanger
program are available. Of specific interest are those documents that establish that your heat
exchanger program satisfies NRC regulatory requirements and conforms to applicable NRC
guidance. Also, appropriate personnel knowledgeable of safety-related heat exchangers should
be available to support the inspector at the site during the inspection.
We have discussed the schedule for this inspection activity with your staff and understand that
our regulatory contact for this inspection will be Taylor Coles of your licensing organization. If
there are any questions about this inspection or the material requested, please contact the
inspector, Jim Drake, by telephone at 817-200-1558 or by e-mail at James.Drake@nrc.gov.
This letter does not contain new or amended information collection requirements subject
to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information
collection requirements were approved by the Office of Management and Budget, control
number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to
respond to, a request for information or an information collection requirement unless the
requesting document displays a currently valid Office of Management and Budget control
number.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice and Procedure, 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 Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic
Reading Room).

Triennial Heat Sink Performance Inspection
Grand Gulf Nuclear Station
Inspection Report: 05000416/2016003
Inspection Dates: September 19 - 23, 2016
Inspection Procedure: IP 71111.07, Triennial Heat Sink Performance
Inspector: Jim Drake, Senior Reactor Inspector
Information Requested for the In-Office Preparation Week
The following information should be sent to the Region IV office in hard copy or electronic
format (Certrec IMS preferred), to the attention of Jim Drake, by September 12, 2016. The
inspector will select specific items from the information requested below and then request from
your staff additional documents needed during the onsite inspection week. Also, we request
that you categorize the documents in your response with the numbered list below. Please
provide requested documentation electronically if possible. If requested documents are large
and only hard copy formats are available, please inform the inspector, and provide subject
documentation during the first day of the onsite inspection. If you have any questions regarding
this information request, please call the lead inspector as soon as possible.
