SUBJECT: DUANE ARNOLD ENERGY CENTER - REQUEST FOR INFORMATION FOR AN | |||
NRC TRIENNIAL BASELINE DESIGN BASES ASSURANCE INSPECTION | |||
(TEAM): INSPECTION REPORT 05000331/2017008 | |||
Dear Mr. Curtland: | |||
On May 1, 2017, the U. S. Nuclear Regulatory Commission (NRC) will begin a Triennial | |||
Baseline Design Bases Assurance Inspection (Team) at your Duane Arnold Energy Center. | |||
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 in-office | |||
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: April 24 - 28, 2017 | |||
Onsite weeks: May 1 - 5, 2017; and May 15 - 19, 2017. | |||
D. Curtland -2- | |||
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 | |||
March 13, 2017. By April 7, 2017, 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 April 19, 2017. 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 | |||
May 1, 2017. 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 Mr. James Neurauter. We understand that our licensing | |||
contact for this inspection is Ms. Tracy Weaver of your organization. If there are any questions | |||
about the inspection or the material requested in the enclosure, please contact the lead | |||
inspector 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. | |||
D. Curtland -3- | |||
This letter and its enclosure will be made available for public inspection and copying at | |||
http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in | |||
accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding. | |||

SUBJECT: DUANE ARNOLD ENERGY CENTER - REQUEST FOR INFORMATION FOR AN
NRC TRIENNIAL BASELINE DESIGN BASES ASSURANCE INSPECTION
(TEAM): INSPECTION REPORT 05000331/2017008
Dear Mr. Curtland:
On May 1, 2017, the U. S. Nuclear Regulatory Commission (NRC) will begin a Triennial
Baseline Design Bases Assurance Inspection (Team) at your Duane Arnold Energy Center.
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 in-office
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: April 24 - 28, 2017
Onsite weeks: May 1 - 5, 2017; and May 15 - 19, 2017.
D. Curtland -2-
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
March 13, 2017. By April 7, 2017, 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 April 19, 2017. 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
May 1, 2017. 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 Mr. James Neurauter. We understand that our licensing
contact for this inspection is Ms. Tracy Weaver of your organization. If there are any questions
about the inspection or the material requested in the enclosure, please contact the lead
inspector 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.
