05000266/2018004; 05000301/2018004
Dear Mr. Craven:
On October 9, 2018, the U. S. Nuclear Regulatory Commission (NRC) will begin the Baseline
Inservice Inspection (Procedure 71111.08). This onsite inspection is scheduled to be performed
October 9, 2018, through October 26, 2018.
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 onsite 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. T. Schneider, of your organization. If there are
any questions about this inspection or the material requested, please contact the lead inspector
Mr. J. Neurauter at 630 829-9828 or via e-mail at James.Neurauter@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.
