SUBJECT: BRAIDWOOD STATION, UNITS 1 AND 2 - NOTIFICATION OF NRC TRIENNIAL
FIRE PROTECTION BASELINE INSPECTION REQUEST FOR INFORMATION
05000456/2015007; 05000457/2015007
Dear Mr. Hanson:
On July 27, 2015, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial fire
protection baseline inspection at your Braidwood Station, Units 1 and 2. This inspection will be
performed in accordance with Inspection Procedure (IP) 71111.05T, the NRCs baseline fire
protection inspection procedure.
Changes were made to the IP 71111.05T which now requires the fire protection inspection to
review your actions to mitigate postulated events that could potentially cause loss of large areas
of power reactor facilities due to explosions or fires. This requirement was implemented by the
issuance of the Interim Compensatory Measures Order EA-02-026, Section B.5.b, and the
subsequent requirements of Title 10, Code of Federal Regulations (CFR) Part 50.54(hh)(2),
which are collectively referred to as B.5.b requirements. During this inspection, the B.5.b
requirements review will be performed during the first onsite week of the inspection starting on
July 29, 2015.
The schedule for the onsite inspection activity is as follows:
Information Gathering Visit: July 27-29, 2015;
B.5.b Requirements: July 29-31, 2015; and
Fire Protection Inspection: August 10-14 and August 24-28, 2015.
The purpose of the information gathering visit is: (1) to obtain information and documentation
needed to support the inspection; (2) to become familiar with the Braidwood Stations fire
protection programs, fire protection features, post-fire safe shutdown capabilities, and plant
layout; and (3) to arrange administrative details, such as office space, availability of
knowledgeable office personnel and to ensure unescorted site access privileges.

Experience has shown that the baseline fire protection inspections 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 for both organizations, we have
enclosed a request for documents needed for the inspection. These documents have been
divided into four groups.
The first group lists information necessary to aid the inspection team in choosing specific focus
areas for the inspection. It is requested that this information be provided to the lead inspector
via mail or electronically no later than July 10, 2015.
The second group also lists information and areas for discussion necessary to aid the inspection
team in choosing specific fire protection focus areas for the inspection and to ensure that the
inspection team is adequately prepared for the inspection. It is requested this information be
available during the information gathering visit July 27, 2015.
The third group of requested documents consists of those items that the team will review, or
need access to, during the inspection. Please have this information available by the first day of
the second onsite inspection week August 10, 2015.
The fourth group lists the 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. 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.
The lead inspector for this inspection is Mr. Dariusz Szwarc. We understand that our regulatory
contact for this inspection is Mr. Murtaza Abbas of your organization. If there are any questions
about the inspection or the material requested, please contact the lead inspector at
(630) 829-9803 or via e-mail at Dariusz.Szwarc@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.
