SUBJECT: DIABLO CANYON POWER PLANT, UNITS 1 AND 2 - NOTIFICATION
OF CYBER SECURITY INSPECTION (NRC INSPECTION
REPORT 05000275/2020401 AND 05000323/2020401) AND
REQUEST FOR INFORMATION
Dear Mr. Welsch:
On April 27, 2020, the U.S. Nuclear Regulatory Commission (NRC) will begin an inspection in
accordance with Inspection Procedure (IP) 71130.10P, Cyber Security, Revision 0, at Diablo
Canyon Power Plant, Units 1 and 2. This inspection evaluates and verifies your ability to meet
the full implementation requirements of the NRCs Cyber Security Rule, Title 10, Code of
Federal Regulations (CFR), Part 73, Section 54, Protection of Digital Computer and
Communication Systems and Networks. The onsite portion of the inspection will take place
during the weeks of April 27 and May 11, 2020.
Experience has shown that these inspections are extremely resource intensive, both for the
NRC inspectors and 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
documents needed for the inspection. The document request has been divided into four
groups.
The first group specifies information necessary to assist the team in choosing the focus areas
(i.e., sample set) to be inspected in accordance with the cyber security inspection procedure.
This information should be made available using either a secure document management
service or passive media (i.e. CD, DVD) and delivered to the regional office no later than
March 9, 2020. The inspection team will review this information and by the end of the planned
information gathering visit on April 10, 2020, will request the specific items that should be
provided for review.
The second group of requested documents will assist the team in their evaluation of the critical
systems and critical digital assets, defensive architecture, and the areas of the cyber security
plan selected for inspection. This information will be requested for our review in the regional
office prior to the inspection, by April 20, 2020.
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 onsite inspection, April 27, 2020.
J. Welsch 2
The fourth group of information is necessary to aid the 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 Sam Graves. We understand that our regulatory
contact for this inspection is Amanda Sorensen and our technical contact is Chance Siri. If
there are any questions about the inspection or the material requested, please contact the lead
inspector at 817-200-1102 or by e-mail at Samuel.Graves@nrc.gov.

I. Information Requested for In-Office Preparation
The initial request for information (i.e., first RFI) provides the team with the general
information necessary to select appropriate components and cyber security plan
elements to develop a site-specific inspection plan. The team will use the first set of
information requested to identify the list of critical systems and critical digital assets
plus operational and management security control portions of the cyber security plan
to be chosen as the sample set required to be inspected during this inspection. The
first information request is specified in Table RFI #1. Provide the first set of
information to the team lead in the regional office, by March 9, 2020, or sooner, to
facilitate the selection of the specific items that will be reviewed during the onsite
inspection weeks.
The requested information shall be provided on either a secure document management
service or passive media (i.e. CD or DVD) to the lead inspector. If passive media is
chosen, please provide four copies of each media submitted (i.e., one for each
inspector/contractor). The preferred file format for all lists is a searchable Excel
spreadsheet file on a CD or DVD. These files should be indexed and hyperlinked to
facilitate efficient review. If you have any questions regarding this information, please
contact the inspection team lead as soon as possible.
