| | Dear Mr. Halpin |
| | 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 your Diablo Canyon Power |
| | Plant. The inspection will be comprised of two reactor inspectors from the NRC Region IV |
| | office. The inspection will be conducted in accordance with NRC Inspection Procedure |
| | 71111.07, "Heat Sink Performance." |
| | The schedule for the inspection is as follows: |
| | Onsite Inspection Dates: September 9 - 12, 2013 |
| | 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 August 26, 2013. 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. |

SUBJECT: DIABLO CANYON POWER PLANT - NOTIFICATION OF NRC TRIENNIAL
HEAT SINK PERFORMANCE INSPECTION (05000275/2013004 AND
05000323/2013004) AND REQUEST FOR INFORMATION
Dear Mr. Halpin
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 your Diablo Canyon Power
Plant. The inspection will be comprised of two reactor inspectors from the NRC Region IV
office. The inspection will be conducted in accordance with NRC Inspection Procedure
71111.07, "Heat Sink Performance."
The schedule for the inspection is as follows:
Onsite Inspection Dates: September 9 - 12, 2013
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 August 26, 2013. 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.
E. Halpin -2-
We have discussed the schedule for this inspection activity with your staff and understand that
our regulatory contact for this inspection will be Mike McCoy of your licensing organization. If
there are any questions about this inspection or the material requested, please contact the
inspectors, Wayne Sifre, at 817-200-1193 or by e-mail at Wayne.Sifre@nrc.gov, or Christie Hale
at 650-479-5434 or e-mail at Christie.Hale@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 http://www.nrc.gov/reading-

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 Wayne Sifre, by August 26, 2013. 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.
