INFORMATION REQUEST FOR NRC TRIENNIAL BASELINE
COMPONENT DESIGN BASES INSPECTION NRC INSPECTION
REPORT 05000382/2011007
Dear Mr. Kowalewski:
On August 22, 2011, the NRC will begin a triennial baseline Component Design Bases
Inspection at the Waterford Steam Electric Station, Unit 3. A six-person team will
perform this inspection using NRC Inspection Procedure 71111.21, "Component Design
Bases Inspection."
The inspection focuses on components and operator actions that have high risk and low
design margins. 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 a
senior reactor analyst, and 3-weeks of onsite inspection by the team. The inspection will
consist of four NRC inspectors, one inspector in training, and two contractors, of which
four will focus on engineering and one on operations. The current inspection schedule is
as follows:
Onsite information gathering visit: Week of August 22, 2011
Preparation Week: August 29, 2011
Onsite weeks: September, 52011; September 19, 2011; October 3,2011
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 of time 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.

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
three 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 August 15, 2011. Insofar as possible, this information should be
provided electronically to the lead inspector. Since the inspection will be concentrated
on high risk/low margin components, calculations associated with your list of high risk
components 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 is those items that the team will need access
to during the preparation week in order to finalize the samples to be inspected. The third
group 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. Additional requests by
inspectors wiii be made throughout aii three onsite weeks for specific documents needed
to complete the review of that component/selection. 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.
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 Wayne C. Sifre. We understand that our
licensing engineer contact for this inspection is Billy Steelman. If there are any
questions about the inspection or the requested materials, please contact the lead
inspector at (817) 860-8193 or via e-mail at ."-~"":c~::c"""~.:;~'"";;~:..="-'-'"
In accordance with 1 0 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 NRC's document
system (ADAMS). ADAMS is accessible from the NRC Web site at

Information Requested Prior to the information Gathering Visit (August 22,
2011)
The following information (Section I of this enclosure) should be sent to the
Region IV office in hard copy or electronic format (ims.certrec.com or compact
disc, preferred), in care of Wayne C. Sifre, by August 15, 2011 to facilitate the
reduction in the items to be selected for a final list during the preparation week of
August 22. 2011. The inspection team will finalize the selected list during the
prep week using the additional documents requested in Section II of this
enclosure. The specific items selected from the lists shall be available and ready
for review on the day indicated in this request. *Please provide requested
documentation electronically in "pdf" files, Excel, or other searchable formats, if
possible. The information should contain descriptive names, and be indexed and
hyperlinked to facilitate ease of use. Information in "lists" should contain enough
information to be easily understood by someone who has knowledge of
pressurized water reactor technology. If requested documents are large and only
hard copy formats are available, please inform the inspector(s), and provide
subject documentation during the first day of the onsite inspection.
