SUBJECT: COMMANCHE PEAK NUCLEAR POWER PLANT - NOTIFICATION OF NRC
TRIENNIAL HEAT EXCHANGER INSPECTION REPORT 05000445/2014004
AND 05000446/2014004
Dear Mr. Flores:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission, Region IV,
staff will conduct a triennial heat sink performance inspection at the Comanche Peak Nuclear
Power Plant. The inspection will be comprised of one reactor inspector from the NRC Region IV
office. The inspection will be conducted in accordance with Inspection Procedure 71111.07,
"Heat Sink Performance."
The schedule for the inspection is as follows:
Onsite inspection - July 7-11, 2014
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 onsite 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 June 30, 2014. We request
that during the onsite 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 Gary Merka of your licensing organization. If
there are any questions about this inspection or the material requested, please contact the
inspector, Jim Melfi, at 817-200-1523 or by email, Jim.Melfi@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, 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

Heat Sink Performance Inspection Document Request
Inspection Dates: July 7-11, 2014
Inspection Procedures: IP 71111.07, Triennial Heat Sink Performance
Inspector: Jim Melfi, Project Engineer
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 (ims.certrec.com database preferred), in care of Jim Melfi, by June 30, 2014. The
inspectors will select specific items from the information requested below and then request from
your staff additional documents needed during the on-site inspection week. We also 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.
