SUBJECT: BYRON STATION, UNITS 1 AND 2 - NOTIFICATION OF NRC TRIENNIAL
FIRE PROTECTION BASELINE INSPECTION REQUEST FOR INFORMATION;
INSPECTION REPORT 05000454/2016007; 05000455/2016007
Dear Mr. Hanson:
On June 6, 2016, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial fire
protection baseline inspection at your Byron Station, Units 1 and 2. This inspection will be
performed in accordance with Inspection Procedure 71111.05T, the NRCs baseline fire
protection inspection procedure.
Changes were made to the Inspection Procedure 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,
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 June 8, 2016.
The schedule for the onsite inspection activity is as follows:
Information Gathering Visit: June 6 - 8, 2016;
B.5.b Requirements: June 8 - 10, 2016; and
Fire Protection Inspection: June 20 - 24 and July 5 - 8, 2016.
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 Byron 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.
B. Hanson
-2-
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 May 20, 2016. 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 June 6, 2016. 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 June 20, 2016. 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. Mark Jeffers. We understand that our regulatory
contact for this inspection is Ms. Amanda Corrigan of your organization. If there are any
questions about the inspection or the material requested, please contact the lead inspector
at (630) 829-9798 or via e-mail at Mark.Jeffers@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 Title 10 of the Code of Federal Regulations (10 CFR) 2.390, Public
Inspections, Exemptions, Requests for Withholding, of the NRC's "Rules of Practice," a copy
of this letter, its enclosure, and your response (if any) will be available electronically for public
inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS)
component of the NRC's Agencywide Documents Access and Management System (ADAMS).
