SUBJECT: POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 REQUEST FOR
INFORMATION FOR AN NRC TRIENNIAL BASELINE COMPONENT DESIGN
BASES INSPECTION (CDBI) REPORT 05000266/2011009; 05000301/2011009
Dear Mr. Meyer:
On August 1, 2011, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial
baseline Component Design Bases Inspection (CDBI) at your Point Beach Nuclear Plant. A
team of six inspectors will perform this 3-week inspection. This inspection will be performed in
accordance with NRC Baseline Inspection Procedure (IP) 71111.21.
The CDBI focuses on the design, maintenance, and operation of risk significant components
associated with one or more accident scenarios. The components to be reviewed during this
baseline inspection will be identified during the in-office preparation week that occurs prior to the
first on-site inspection week. In addition, operating experience issues, associated with the
component samples, will also be selected for review.
The inspection will include three weeks on-site. The inspection team will consist of six NRC
inspectors, of which five will focus on engineering and one on operations. The current
inspection schedule is as follows:
- On-site weeks: August 1 through 5, 2011;
August 15 through 19, 2011; and
August 29 through September 2, 2011.
The team will be preparing for the inspection, mainly during the week of July 25, 2011, as
discussed in the attached enclosure. A Region III Senior Reactor Analyst may accompany the
inspection team during the week of August 1, 2011, to review probabilistic risk-assessment
data, and assist in identifying risk significant components and/or specific component functions,
which will be reviewed during the inspection.
Experience with previous baseline design 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 on-site 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 June 3, 2011. By
June 24, 2011, the lead inspector will communicate the initial selected set of approximately
20 components.
- 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
initial selected components, should be provided to the lead inspector at the Regional Office
no later than July 15, 2011. During the in-office preparation activities, the team may identify
additional information needed to support the inspection.
- The last group includes the additional information mentioned above, as well as plant
specific reference material. This information should be available to the team on-site on
August 1, 2011. 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. Alan Dahbur. We understand that our licensing
contact for this inspection is Ms. Kim Locke 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) 829-9810 or via e-mail at alan.dahbur@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 NRCs Rules of Practice, a copy of this letter and its
enclosure will be available electronically for public inspection in the NRC Public Document
Room or from the Publicly Available Records (PARS) component of NRCs document system
(ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the

I. Information Requested Prior to the On-site Information Gathering/Inspection Week
The following information is requested by June 3, 2011, or sooner, to facilitate inspection
preparation. If you have any questions regarding this information, please call the team
leader as soon as possible. (Please provide the information electronically in pdf files,
Excel, or other searchable formats, preferably on some portable electronic media (e.g.,
CDROM, DVD, flash drive, etc.). The portable electronic media 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 light water reactor technology. Inspection Procedure 71111.21
describes three approaches to use in selecting components: (1) system; (2) risk
significance/low margin; and (3) event scenario-based. During this inspection, the
inspectors will primarily use the system-approach and select components associated
with the Auxiliary Feedwater System (AFW) and its supporting systems/equipment.
Therefore, please clearly identify items pertaining to the AFW system and supporting
equipment. However, additional components not associated with AFW may be selected
at the team leaders discretion.
1. Risk ranking of top 250 components from your site specific probabilistic safety
analysis (PSA) sorted by Risk-Achievement Worth (RAW). Include values for
Birnbaum Importance, Risk-Reduction Worth (RRW), and Fussell-Veseley (FV)
(as applicable). In addition, provide similar information of all components
associated with the AFW system.
2. Risk ranking of top 100 components from your site specific PSA sorted by Large
Early Release Frequency (LERF), including all components associated with the
AFW system.
3. Provide a list of the top 200 cut-sets from your PSA.
