NUCLEAR REGULATORY COMMISSION
REGION III
2443 WARRENVILLE RD. SUITE 210
LISLE, IL 60532-4352
August 28, 2015
Mr. Anthony Vitale
Vice President, Operations
Entergy Nuclear Operations, Inc.
Palisades Nuclear Plant
27780 Blue Star Memorial Highway
Covert, MI 49043-9530
SUBJECT: PALISADES NUCLEAR PLANT - NOTIFICATION OF AN NRC TRIENNIAL
HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR INFORMATION
INSPECTION REPORT 05000255/2015004
Dear Mr. Vitale:
On November 16, 2015, the U.S. Nuclear Regulatory Commission (NRC) will begin the onsite
portion of the Triennial Heat Sink Performance Inspection at your Palisades Nuclear Plant. This
inspection will be performed in accordance with NRC baseline Inspection procedure 71111.07.
In order to minimize the impact that the inspection has on the site and to ensure a productive
inspection, we have enclosed a request for documents needed for the inspection. The
documents have been divided into three groups.
The first group lists information necessary for our initial inspection scoping activities. This
information should be available to the lead inspector no later than October 1, 2015. By
October 13, 2015, the inspector will communicate the initial selected set of approximately
2-3 risk-significant heat exchangers.
The second group is needed to support our in-office preparation activities. This set of
documents, including the calculations associated with the selected heat exchangers, should
be available at the Regional Office no later than November 5, 2015. This information should
be separated for each selected component, especially if provided electronically (e.g., folder
with component name that includes calculations, condition reports, maintenance history, etc.).
During the in-office preparation activities, the inspector may identify additional information
needed to support the inspection.
The last group includes the additional information above as well as plant specific reference
material. This information should be available onsite to the inspector on November 16, 2015.
It is also requested that corrective action documents and/or questions developed during the
inspection be provided to the inspector as the documents are generated.
All requested documents are to be for the time period from the onsite inspection period back
to the documents that were provided in response to the previous Heat Sink Performance
Inspection. If no activities were accomplished in that time period, then the request applies to
the last applicable document in the previous time period. It is important that these documents
be as complete as possible, in order to minimize the number of documents requested during
the preparation week or during the onsite inspection.
