SUBJECT: DONALD C. COOK NUCLEAR POWER PLANT, UNIT 1 - NOTIFICATION OF
NRC BASELINE INSPECTION AND REQUEST FOR INFORMATION
(05000315/2017003; 05000316/2017003)
Dear Mr. Gebbie:
On September 18, 2017, the U. S. Nuclear Regulatory Commission (NRC) will begin the
Baseline Inservice Inspection (Procedure 71111.08). This onsite inspection is scheduled to be
performed September 18, 2017, through September 28, 2017.
Experience has shown that this inspection is resource intensive both for the NRC inspector and
your staff. In order to minimize the impact to your on-site resources, and to ensure a productive
inspection for both sides, we have enclosed a request for documents needed for this inspection.
These documents have been divided into two groups. The first group identifies information
necessary to ensure that the inspector is adequately prepared. The second group identifies the
information the inspector will need upon arrival at the site. It is important that all of these
documents are up-to-date, and complete, in order to minimize the number of additional
documents requested during the preparation and/or the onsite portions of the inspection.
We have discussed the schedule for inspection activities with your staff and understand that our
regulatory contact for this inspection will be Mr. M. Ellet, of your organization. If there are any
questions about this inspection or the material requested, please contact the lead inspector
Mr. M. Holmberg at 630-829-9748 or via e-mail at msh@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.
