Executive Vice President Nuclear/
Chief Nuclear Officer
Arizona Public Service Company
P.O. Box 52034, MS 7602
Phoenix, AZ 85072-2034
SUBJECT: PALO VERDE NUCLEAR GENERATING STATION - NOTIFICATION OF NRC
DESIGN BASES ASSURANCE INSPECTION (TEAMS) (05000528/2019011,
05000529/2019011, AND 05000530/2019011) AND INITIAL REQUEST FOR
INFORMATION
Dear Mr. Bement:
On January 24, 2019, the NRC will begin a triennial baseline design bases assurance
inspection at the Palo Verde Nuclear Generating Station. A six person team will perform this
inspection using NRC Inspection Procedure (IP) 71111, Attachment 21M, Design Bases
Assurance Inspection (Teams).
The inspection focuses on the maintenance of the design bases and modifications made to
structures, systems, and components. The samples reviewed during this inspection will be
identified during an information gathering visit. In addition, a number of operating experience
issues will also be selected for review during the in-office preparation week.
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 and two NRC
contractors, who will focus on engineering, and one NRC inspector that will focus on operations.
The current inspection schedule is as follows:
Onsite Information Gathering Visit: January 24, 2019
Preparation Week: February 4-8, 2019
Onsite Weeks: February 11-15, 2019, and February 25, 2019 - March 1, 2019
The purpose of the information gathering visit is to meet with members of your staff to identify
potential risk-significant components and operator actions. The lead inspector will also request
a tour of the plant with members of your operations staff and probabilistic safety assessment
staff. During the onsite weeks, several days and administration will be needed on the plant-
referenced simulator in order to facilitate the development of operator action-based scenarios.
R. Bement 2
Additional information and documentation needed to support the inspection will be identified
during the inspection, including interviews with engineering managers, engineers, and
probabilistic safety assessment staff.
Our experience with these inspections has shown that they 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, we have enclosed a request for information
needed for the inspection. The request has been divided into two groups. The first group lists
information necessary for the information gathering visit and for general preparation. This
information should be available to the regional office no later than January 21, 2019, unless
otherwise stated. If possible, this information should be provided electronically to the lead
inspector. Since the inspection will be concentrated on high risk/low margin components and
modifications, calculations associated with your list of high risk components and modifications
should be available to review during the information gathering visit to assist in our selection of
components based on available design margin.
The second group of documents requested lists 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. An additional request will be made by the team during the preparation week once
the specific components and modifications have been selected. Additional requests by
inspectors will also be made throughout the onsite weeks for specific documents needed to
complete the review. 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
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 Gerond A. George, Senior Reactor Inspector. We
understand that our licensing engineer contact for this inspection is Ms. L. Weaver. If there are
any questions about the inspection or the requested materials, please contact the lead inspector
by telephone at 817-200-1562 or by e-mail at Gerond.George@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 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be
made available electronically for public inspection in the NRC Public Document Room or from
R. Bement 3
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
