SUBJECT: COMANCHE PEAK NUCLEAR POWER PLANT, UNITS 1 AND 2 -
NOTIFICATION OF NRC DESIGN BASES ASSURANCE INSPECTION
(PROGRAMS) (05000445/2020010 AND 05000446/2020010) AND INITIAL
REQUEST FOR INFORMATION
Dear Mr. Peters:
On August 10, 2020, the U.S. Nuclear Regulatory Commission (NRC) will begin an onsite
inspection at the Comanche Peak Nuclear Power Plant. A three-person team will perform this
inspection using NRC Inspection Procedure 71111.21N.02, Design Bases Inspection
(Programs), Attachment 2, Design-Basis Capability of Power-Operated Valves Under
Title 10 of the Code of Federal Regulations (10 CFR) 50.55a Requirements.
This inspection will evaluate the reliability, functional capability, and design basis of
risk-important power-operated valves as required by 10 CFR 50.55a and applicable
10 CFR Part 50, Appendix A and Appendix B, requirements, and as required by the Comanche
Peak Nuclear Power Plant Operating License. Additionally, the team will perform an inspection
of the documentation files to verify that the plant activities associated with safety-related
motor-operated valves meet your commitments to Generic Letter (GL) 89-10, Safety-Related
Motor-Operated Valve Testing and Surveillance, and GL 96-05, "Periodic Verification of
Design-Basis Capability of Safety-Related Motor-Operated Valves." In conducting this
inspection, the team will select power-operated valves used to prevent and mitigate the
consequences of a design basis accident.
The inspection will include an information gathering site visit by the team leader and 2 weeks of
onsite inspection by the team. The inspection will consist of three NRC inspectors. The current
inspection schedule is as follows:
Onsite Information Gathering Visit: July 28-29, 2020
Preparation Weeks: August 3-7, 2020, and August 17 - 21, 2020
Onsite Weeks: August10-14, 2020, and August 24 - 28, 2020

The purpose of the information gathering visit is to meet with members of your staff to become
familiar with the power-operated valve activities at the Comanche Peak Nuclear Power Plant.
The lead inspector will request a meeting with your personnel to discuss the site power-
operated valve procedures. Additionally, the lead inspector will request a discussion with your
staff to become familiar with the regulations and standards applicable to power-operated valves
at the site. Additional information and documentation needed to support the inspection will be
identified during the inspection, including interviews with engineering managers and engineers.
In order to minimize the inspection impact on the site and to ensure a productive inspection, we
have enclosed a request for information needed for the inspection. This information should be
made available to the lead inspector during the July 28-29, 2020, visit. Since the inspection will
be concentrated on safety-related and risk-significant power-operated valves, a list of such
power-operated valves should be available to review during and following the information
gathering visit to assist in our selection of appropriate power-operated valves to review.
It is requested that this information be provided to the lead inspector as the information is
generated during the inspection. Additional requests by inspectors will be made during the
onsite weeks for specific documents needed to complete the review of specific power-operated
valves and associated activities. 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. In order to facilitate the inspection, we
request that a contact individual be assigned to each inspector to ensure information requests,
questions, and concerns are addressed in a timely manner.
The lead inspector for this inspection is Wayne C. Sifre. We understand that our licensing
engineer contact for this inspection is Gary Murka. If there are any questions about
the inspection or the requested materials, please contact the lead inspector by telephone
at 817-200-1193 or by e-mail at Wayne.Sifre@nrc.gov.

I. Information Requested for Information Gathering Visit (July 28, 2020)
The following information should be provided to the lead inspector in hard copy or
electronic format to the attention of Wayne Sifre by July 20, 2020, to facilitate the
reduction in the items to be selected for a final list of components. The inspection team
will finalize the selected list during the prep week using the documents requested in this
enclosure. The specific items selected from the lists shall be available and ready for
review on the day indicated in this request. *Please provide requested documentation
electronically in pdf files, Excel, or other searchable formats, if possible. The
information 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 pressurized water reactor
technology. If requested documents are large and only hard copy formats are available,
please inform the inspectors and provide subject documentation during the first day of
the onsite inspection.
