SUBJECT: PRAIRIE ISLAND NUCLEAR GENERATING STATIONNOTIFICATION OF NRC

DESIGN BASES ASSURANCE INSPECTION (PROGRAMS) (05000282/202010;

05000306/202010) AND INITIAL REQUEST FOR INFORMATION

Dear Mr. Sharp,

On May 4, 2020, the U.S. Nuclear Regulatory Commission (NRC) will begin an onsite inspection

at the Prairie Island Nuclear Generating Plant. A three-person team will perform this inspection

using NRC Inspection Procedure 71111.21N, Design Bases Inspection (Programs),

Attachment 2, Design-Basis Capability of Power-Operated Valves Under 10 CFR 50.55a

Requirements.

This inspection will evaluate the reliability, functional capability, and design basis of risk-

important power-operated valves (POVs) as required by 10 CFR 50.55a and applicable 10 CFR Part 50, Appendix A and Appendix B requirements, and as required by the Prairie Island

Nuclear Generating 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 (MOVs) 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 POVs used to prevent and mitigate the consequences of a

design basis accident.

The inspection will include an information gathering week 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:

Information Gathering Week: March 23-27, 2020

Preparation Weeks: April 27 - May 1, 2020,

Onsite Weeks: May 4-8, 2020, and May 18-22, 2020

The purpose of the information gathering week is to conference with members of your staff to

become familiar with the POV activities at the Prairie Island Nuclear Generating Plant. The lead

inspector will request a meeting with your personnel to discuss the site POV procedures.

Additionally, the lead inspector will request a discussion with your staff to become familiar with

the regulations and standards applicable to POVs at the site. Additional information and

S. Sharp 2

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 by March 20, 2020. Since the inspection will be

concentrated on safety-related and risk significant POVs, a list of such POVs should be

available to review during and following the information gathering week to assist in our selection

of appropriate POVs to review.

It is requested that this information be provided to the lead inspector as the information is

generated during the inspection. Information gathering week for specific documents needed to

complete the review of specific POVs 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 Michael A. Jones Jr. We understand that our licensing

engineer contact for this inspection is Ms. Carrie Seipp. If there are any questions about

the inspection or the requested materials, please contact the lead inspector by telephone

at 630-829-9745 or by e-mail at Michael.Jones@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.
