SUBJECT: DIABLO CANYON POWER PLANT - NOTIFICATION OF AN NRC TRIENNIAL
FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION
REPORT 05000275/2016008 and 05000323/2016008) AND REQUEST FOR
INFORMATION
Dear Mr. Halpin:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC),
Region IV staff will conduct a triennial fire protection baseline inspection at the Diablo Canyon
Power Plant in October 2016. The inspection team will be comprised of five reactor inspectors
from the NRC Region IV office. The inspection will be conducted in accordance with Inspection
Procedure 71111.05XT, Fire Protection - NFPA 805 (Triennial), the NRCs baseline fire
protection inspection procedure.
The schedule for the inspection is as follows:
- Information gathering visit: August 30 - 31, 2016
- On-site inspection: October 3 - 7, 2016
October 17 - 21, 2016
The purpose of the information gathering visit is to obtain information and documentation
needed to support the inspection and to become familiar with the fire protection program, fire
protection features, safe shutdown success paths, plant layout, and mitigating strategies to
address Section B.5.b of NRC Order EA-02-026, Order for Interim Safeguards and Security
Compensatory Measures, dated February 25, 2002, and 10 CFR 50.54(hh)(2).
The team leader will participate in the information gathering visit to select the fire areas for
evaluation, identify additional documents needed to support the inspection, obtain unescorted
access, and meet with the key personnel who will support the inspection. The fire area
selection will require a walkdown of candidate fire areas with key personnel from your staff. The
enclosures to this letter provide an initial list of the documents the team will need for their
review.
E. Halpin -2-
During the information gathering visit, the team leader will also discuss the following inspection
support administrative details: (1) office space size and location; (2) specific documents
requested to be made available to the team in their office spaces; (3) arrangements for reactor
site access (including radiation protection training, security, safety, and fitness for duty
requirements); and (4) the availability of knowledgeable plant staff and licensing organization
personnel to serve as points of contact during the inspection.
We request that during the on-site inspection weeks you ensure that copies of analyses,
evaluations, or documentation regarding the implementation and maintenance of the station fire
protection program, including the success path necessary to achieve and maintain the nuclear
safety performance criteria, be readily accessible to the team for their review. Of specific
interest for the fire protection portion of the inspection are those documents which establish that
your fire protection program satisfies NRC regulatory requirements and conforms to applicable
NRC and industry fire protection guidance (i.e., fire protection compliance assessment
documents). For the 10 CFR 50.54(hh)(2) portion of the inspection, those documents
implementing your mitigating strategies and demonstrating the management of your
commitments for the strategies are of specific interest. Also, personnel should be available at
the site during the inspection who are knowledgeable regarding those plant systems required to
achieve and maintain safe and stable plant conditions, including the electrical aspects of the
nuclear safety capability assessment, reactor plant fire protection systems and features, and the
station fire protection program and its implementation.
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 under 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 and Procedure, 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). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-
rm/adams.html (the Public Electronic Reading Room).
Your cooperation and support during this inspection will be appreciated. If you have questions
concerning this inspection or the inspection teams information or logistical needs, please
E. Halpin -3-
contact Dr. Steven Alferink, the team lead inspector, in the Region IV office at (817) 200-1548 or

Triennial Fire Protection Inspection Document Request
The documents and information requested below should generally be made available to the
inspection team during the inspection. Electronic format is the preferred format, except where
specifically noted. If electronic files are made available via the internet-based inspection
management system (IMS), then the remote document access must allow inspectors to
download, save, and print the documents in the NRCs regional office.
If IMS is utilized, it is recommended that a separate folder be used corresponding to each item
listed below and that multiple documents within each folder be combined into a ZIP file before
uploading. Electronic files on compact disc or paper records (hard copy) are also acceptable.
To allow review before the on-site information gathering visit, the following documents should be
made available to the team in the regional office no later than August 15, 2016:
- Post-fire nuclear safety capability, systems, and separation analysis (request A.1)
- Fire hazards analysis and/or NFPA 805 design basis document (request A.2)
- Fire probabilistic risk assessment (PRA) summary document or full PRA document
(request A.3)
- Fire risk evaluations (i.e., NFPA 805, Section 2.4.3) (request A.5)
- Plant change evaluations (i.e., NFPA 805, Section 2.4.4) (request A.6)
- Analysis that demonstrates nuclear safety performance criteria can be achieved and
maintained for those areas that require recovery actions (request A.7)
Based on a review of the above seven items, the team leader should identify a preliminary list of
fire areas being considered for inspection prior to the on-site information gathering visit. During
the information gathering visit, or shortly thereafter, the fire areas selected for inspection will be
determined.
This document request is based on typical documents that a generic plant might have. As such,
this generic document request is not meant to imply that any specific plant is required to have all
of the listed documents. It is recognized that some documents listed below may not be
available for your plant. In addition, the document titles listed below are based on typical
industry document names; your plant-specific document titles may vary.
To allow review before the on-site inspection weeks, the following documents should be made
available to the team in the regional office no later than September 12, 2016.
