SUBJECT: NOTIFICATION OF SEQUOYAH NUCLEAR PLANT DESIGN BASES

ASSURANCE INSPECTION (TEAM) - U.S. NUCLEAR REGULATORY

COMMISSION INSPECTION REPORT 05000327/2022010 AND

Dear Mr. Barstow:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

Region II staff will conduct a Design Bases Assurance Inspection (DBAI) at your Sequoyah

Nuclear Plant Units 1 & 2 during the weeks of February 28 and March 14, 2022. Mr. R.

Patterson, a Sr. Reactor inspector from the NRCs Region II office, will lead the inspection team.

The inspection will be conducted in accordance with Inspection Procedure 71111.21M, Design

Bases Assurance Inspection (Teams), dated December 8, 2016 (ADAMS ML16238A320).

The inspection will evaluate the capability of components that have been modified and risk-

significant/low-margin components to function as designed and to support proper system

operation. The inspection will also include a review of selected operator actions, operating

experience, and modifications.

During a telephone conversation on December 14, 2021, with Scott, Bowman we confirmed

arrangements for an information-gathering site visit and the two-week onsite inspection. The

schedule is as follows:

  • Information-gathering visit: Week of February 7, 2022
  • Onsite weeks: Weeks of February 28 and March 14, 2022

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

components that have been modified, risk-significant components and operator actions.

Information and documentation needed to support the inspection will also be identified.

Mr. Shane Sandal, a Region II Senior Risk Analyst, will support Mr. Patterson during the

information-gathering visit to review probabilistic risk assessment data and identify components

to be examined during the inspection. Additionally, during the onsite weeks, time will be needed

on the plant-
