SUBJECT: PALO VERDE NUCLEAR GENERATING STATION - NOTIFICATION OF NRC

DESIGN BASES ASSURANCE INSPECTION (PROGRAMS)

05000528/2018011, 05000529/2018011, AND 05000530/2018011 INITIAL

REQUEST FOR INFORMATION

Dear Mr. Bement:

On April 24, 2018, the NRC will begin an inspection at the Palo Verde Nuclear Generating

Station. A three-person team will perform this inspection using NRC Inspection

Procedure 71111.21N, Design Bases Inspection (Programs), Attachment 1, Environmental

Qualification under 10 CFR 50.49 Programs, Processes, and Procedures.

This inspection will evaluate the implementation of the environmental qualification of electrical

equipment program, as required by the Palo Verde Nuclear Generating Station Operating

License. Additionally, the team will perform an inspection of the equipment qualification

documentation files to verify that electrical equipment important to safety meets the

requirements of 10 CFR 50.49. The team will select components that will be subjected to harsh

environments and required mitigate the consequences of a design basis accident.

The inspection will include an information gathering site visit by the team leader and risk

analyst, and two weeks of on-site inspection by the team. The inspection will consist of three

NRC inspectors. The current inspection schedule is as follows:

On-site Information Gathering Visit: April 24-26, 2018

Preparation Weeks: April 30-May 4 and May 14-18, 2018

On-site Weeks: May 7-11 and May 21-25, 2018

The purpose of the information gathering visit is to meet with members of your staff to become

familiar with the Palo Verde Nuclear Generating Station environmental qualification program.

The lead inspector will request a meeting with your personnel to discuss the site environmental

qualification program and procedures. Additionally, the lead inspector will request a discussion

with your staff to become familiar with the equipment qualification regulations and standards to

which the site is committed. Additional information and documentation needed to support the

inspection will be identified during the inspection, including interviews with engineering

managers and engineers.

R. Bement 2

Our experience with these inspections has shown that they are 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. This information should be made available to the lead inspector on or before the

April 24, 2018, visit. Since the inspection will be concentrated on the environmental qualification

of the equipment, the equipment qualification master list should be available to review during

the information gathering visit to assist in our selection of components.

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

on-site week for specific documents needed to complete the review of that component/selection.

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 on-site 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 Sifre. We understand that our licensing

engineer contact for this inspection is Sean Dornseif. 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.

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 and Procedure," a copy of

this letter will be made 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).

Sincerely,
