Executive Vice President Nuclear/CNO

Arizona Public Service Company

P.O. Box 52034, MS 7602

SUBJECT: PALO VERDE NUCLEAR GENERATING STATION, UNITS 1, 2, AND 3 - NOTIFICATION OF NRC COMPONENT DESIGN BASES INSPECTION

(05000528/2016007; 05000529/2016007; 05000530/2016007)

AND INITIAL REQUEST FOR INFORMATION

Dear Mr. Edington:

On July 18, 2016, the U.S. Nuclear Regulatory Commission (NRC) w

ill begin a triennial baseline Component Design Bases Inspection at the Palo Verde Generating Station. A seven-person

team will perform this inspection using NRC Inspection Procedure 71111.21, "Component Design Bases Inspection."

The inspection focuses on components and operator actions that have high risk and low design

margins. The samples reviewed during this inspection will be identified during an information

gathering visit and during the subsequent in-office preparation week. In addition, a number of

operating experience issues will also be selected for review.

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

reactor analyst, and 3-weeks of onsite inspection by the team. The inspection will consist of five NRC inspectors and two contractors, of which six

will focus on engineering and one on operations. The current inspection schedule is as follows:

Onsite Information Gathering Visit: July 18 - 22, 2016 Preparation Week: July 25 - 29, 2016

Onsite Weeks: August 1 - 5, 15 - 19, and August 29 - September 2, 2016.

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 of time will be needed on the plant-referenced

simulator in order to facilitate the development of operator action-based scenarios. 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 July 11, 2016. Insofar as

possible, this information should be provided electronically to the lead inspector. Since the

inspection will be concentrated on high risk/low margin components, calculations associated with your list of high risk components 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 have been selected. Additional requests by inspectors will also be made throughout all three onsite weeks 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 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 Sifre. We understand that our licensing engineer contact for this inspection is Mr. Dave Heckman.

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 O

ffice 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 the Publicly Available Records (PARS) component of NRC's document system (ADAMS).

Lead Inspector: Wayne Sifre, Senior Reactor Inspector

I. Information Requested Prior to Information Gathering Visit (July 18, 2016)

The following information (Section I of this enclosure) should be sent to the Region IV

office in hard copy or electronic format (Certrec IMS preferred), to the attention of Wayne

Sifre by July 11, 2016, to facilitate the reduction in the items to be selected for a final list

during the preparation week July 25, 2016. The inspection team will finalize its sample

selections during the prep week and will provide an additional information request with specific items by sample. This information shall be made available by the first day of the onsite portion of the inspection. 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/or only hard copy

formats are available, please inform the inspector(s), and provide subject documentation during the first day of the onsite inspection.
