SUBJECT: DAVIS-BESSE NUCLEAR POWER STATIONREQUEST FOR INFORMATION
FOR AN NRC TRIENNIAL BASELINE DESIGN BASES ASSURANCE
INSPECTION (TEAM), INSPECTION REPORT 05000346/2018011
Dear Mr. Bezilla:
On September 17, 2018, the U.S. Nuclear Regulatory Commission (NRC) will begin a Triennial
Baseline Design Bases Assurance Inspection (Team) at your Davis-Besse Nuclear Power
Station. This inspection will be performed in accordance with NRC Baseline Inspection
Procedure 71111.21M.
The Design Bases Assurance Inspection focuses on the design, maintenance, and operation
of risk significant components with low margin, or associated with an accident scenario, or a
specific system. The inspection also monitors the implementation of modifications to structures,
systems, and components as modifications to one system may also affect the design bases and
functioning of interfacing systems as well as introduce the potential for common cause failures.
The components and modifications to be reviewed during this baseline inspection will be
identified as part of the preparation for the inspection and finalized during the inoffice
preparation week that occurs prior to the first onsite inspection week. In addition, operating
experience issues, associated with the component samples, will also be selected for review.
The inspection team may request scenarios to be performed on the simulator. This request
would require support from your simulator staff to validate scenarios, simulator time, and a crew
to perform the actions, which would most likely occur during the second onsite week. The team
will work closely with your staff early on during the inspection process to ensure this activity can
be accomplished with minimal impact.
The inspection will include 2 weeks onsite. The inspection team will consist of six NRC
inspectors who will focus on engineering/maintenance/operations of the selected components
and modifications. The current inspection schedule is as follows:
- Preparation week: September 10-14, 2018;
- Onsite weeks: September 17-21, 2018; and
October 1-5, 2018.

Experience with previous baseline design/modification inspections of similar depth and length
has shown that this type of inspection is extremely resource intensive, both for the NRC
inspectors and the licensee staff. In order to minimize the inspection impact on the site and to
ensure a productive inspection for both parties, we have enclosed a request for information
needed for the inspection.
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. Insofar as possible, this information should be provided electronically to the lead
inspector. The information request has been divided into three groups:
- The first group lists information necessary for our initial inspection scoping activities.
This information should be provided to the lead inspector no later than August 3, 2018.
By August 21, 2018, the lead inspector will communicate the initial selected set of
approximately seven components and seven modifications.
- The second group of documents requested is those items needed to support our
in-office preparation activities. This set of documents, including the calculations
associated with the initially selected components and the modification packages
associated with the initially selected modifications, should be provided to the lead
inspector at the Regional Office no later than August 31, 2018. During the in-office
preparation activities, the team 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 to the team onsite on
September 17, 2018. It is also requested that corrective action documents and/or
questions developed during the inspection be provided to the lead inspector as the
documents are generated.
The lead inspector for this inspection is Diana Betancourt-Roldan. We understand that our
licensing contact for this inspection is Gerry Wolf of your organization. If there are any
questions about the inspection or the material requested in the enclosure, please contact the
lead inspector at 815-458-2852, or via e-mail at Diana.Betancourt-Roldan@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.
