SUBJECT: COOPER NUCLEAR STATION - NOTIFICATION OF NRC DESIGN BASES | |||
ASSURANCE INSPECTION (TEAMS) (05000298/2018011) AND INITIAL | |||
REQUEST FOR INFORMATION | |||
Dear Mr. Dent: | |||
On March 12, 2018, the NRC will begin a triennial baseline Component Design Bases | |||
Inspection at the Cooper Nuclear Station. A six-person team will perform this inspection using | |||
NRC Inspection Procedure 71111, Attachment 21M, Design Bases Assurance Inspection | |||
(Teams). | |||
The inspection focuses on the maintenance of component design bases and modifications | |||
made to structures, systems, and components. The samples reviewed during this inspection | |||
will be identified during an information gathering visit and during the subsequent in-office | |||
preparation week. In addition, a number of operating experience issues will also be selected for | |||
review. | |||
The inspection will include an information gathering site visit by the team leader, and two weeks | |||
of onsite inspection by the team. The inspection will consist of three NRC inspectors, two | |||
contractors, and one operations examiner. The current inspection schedule is as follows: | |||
On-site Information Gathering Visit: March 12, 2018 | |||
Preparation Week: March 26-30, 2018 | |||
On-site Weeks: April 2-6, 2018; and April 16-20, 2018 | |||
The purpose of the information gathering visit is to meet with members of your staff to identify | |||
potential risk-significant components and operator actions. The lead inspector will also request | |||
a tour of the plant with members of your operations staff and probabilistic safety assessment | |||
staff. During the onsite weeks, several days and administration will be needed on the plant- | |||
referenced simulator in order to facilitate the development of operator action-based scenarios. | |||
Additional information and documentation needed to support the inspection will be identified | |||
during the inspection, including interviews with engineering managers, engineers, and | |||
probabilistic safety assessment staff. | |||
J. Dent, Jr. 2 | |||
Our experience with these inspections has shown that they are 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, we have enclosed a request for information | |||
needed for the inspection. The request has been divided into two groups. The first group lists | |||
information necessary for the information gathering visit and for general preparation. This | |||
information should be available to the regional office no later than March 5, 2018, unless | |||
otherwise stated. If possible, this information should be provided electronically to the lead | |||
inspector. Since the inspection will be concentrated on high risk/low margin components and | |||
modifications, calculations associated with your list of high risk components and modifications | |||
should be available to review during the information gathering visit to assist in our selection of | |||
components based on available design margin. | |||
The second group of documents requested lists information necessary to aid the inspection | |||
team in tracking issues identified as a result of the inspection. It is requested that this | |||
information be provided to the lead inspector as the information is generated during the | |||
inspection. An additional request will be made by the team during the preparation week once | |||
the specific components and modifications have been selected. Additional requests by | |||
inspectors will also be made throughout the onsite weeks for specific documents needed to | |||
complete the review. 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 | |||
onsite portions of the inspection. In order to facilitate the inspection, we request that a contact | |||
individual be assigned to each inspector to ensure information requests, questions, and | |||
concerns are addressed in a timely manner. | |||
The lead inspector for this inspection is Gerond A. George. We understand that our licensing | |||
engineer contact for this inspection is Thomas Forland. If there are any questions about the | |||
inspection or the requested materials, please contact the lead inspector by telephone at | |||
817-521-3555 by e-mail at Gerond.George@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. | |||
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be | |||
made available electronically for public inspection in the NRC Public Document Room or from | |||
the Publicly Available Records (PARS) component of NRCs document system (ADAMS). | |||

SUBJECT: COOPER NUCLEAR STATION - NOTIFICATION OF NRC DESIGN BASES
ASSURANCE INSPECTION (TEAMS) (05000298/2018011) AND INITIAL
REQUEST FOR INFORMATION
Dear Mr. Dent:
On March 12, 2018, the NRC will begin a triennial baseline Component Design Bases
Inspection at the Cooper Nuclear Station. A six-person team will perform this inspection using
NRC Inspection Procedure 71111, Attachment 21M, Design Bases Assurance Inspection
(Teams).
The inspection focuses on the maintenance of component design bases and modifications
made to structures, systems, and components. The samples reviewed during this inspection
will be identified during an information gathering visit and during the subsequent in-office
preparation week. In addition, a number of operating experience issues will also be selected for
review.
The inspection will include an information gathering site visit by the team leader, and two weeks
of onsite inspection by the team. The inspection will consist of three NRC inspectors, two
contractors, and one operations examiner. The current inspection schedule is as follows:
On-site Information Gathering Visit: March 12, 2018
Preparation Week: March 26-30, 2018
On-site Weeks: April 2-6, 2018; and April 16-20, 2018
The purpose of the information gathering visit is to meet with members of your staff to identify
potential risk-significant components and operator actions. The lead inspector will also request
a tour of the plant with members of your operations staff and probabilistic safety assessment
staff. During the onsite weeks, several days and administration will be needed on the plant-
referenced simulator in order to facilitate the development of operator action-based scenarios.
Additional information and documentation needed to support the inspection will be identified
during the inspection, including interviews with engineering managers, engineers, and
probabilistic safety assessment staff.

Our experience with these inspections has shown that they are 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, we have enclosed a request for information
needed for the inspection. The request has been divided into two groups. The first group lists
information necessary for the information gathering visit and for general preparation. This
information should be available to the regional office no later than March 5, 2018, unless
otherwise stated. If possible, this information should be provided electronically to the lead
inspector. Since the inspection will be concentrated on high risk/low margin components and
modifications, calculations associated with your list of high risk components and modifications
should be available to review during the information gathering visit to assist in our selection of
components based on available design margin.
The second group of documents requested lists information necessary to aid the inspection
team in tracking issues identified as a result of the inspection. It is requested that this
information be provided to the lead inspector as the information is generated during the
inspection. An additional request will be made by the team during the preparation week once
the specific components and modifications have been selected. Additional requests by
inspectors will also be made throughout the onsite weeks for specific documents needed to
complete the review. 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
onsite portions of the inspection. In order to facilitate the inspection, we request that a contact
individual be assigned to each inspector to ensure information requests, questions, and
concerns are addressed in a timely manner.
The lead inspector for this inspection is Gerond A. George. We understand that our licensing
engineer contact for this inspection is Thomas Forland. If there are any questions about the
inspection or the requested materials, please contact the lead inspector by telephone at
817-521-3555 by e-mail at Gerond.George@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

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be
made available electronically for public inspection in the NRC Public Document Room or from
the Publicly Available Records (PARS) component of NRCs document system (ADAMS).
