August 2, 2024 MEMORANDUM TO: Gerond A. George, Chief Licensing Projects Branch Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation FROM:

James V. Delosreyes, Project Manager /RA/

Licensing Projects Branch Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation

SUBJECT:

UPDATE TO THE ACCIDENT TOLERANT FUEL ROADMAP TO READINESS The purpose of this memorandum is to transmit an update to the accident tolerant fuel (ATF)

Roadmap to Readiness graphic. As a complement to the ATF project plan (Agencywide Documents Access and Management System (ADAMS) Accession No. ML21243A298), it has provided: (1) a graphical representation of the project timeline; (2) project efficiency and reliability; (3) regulatory certainty of licensing near-term ATF, increased enrichment, and higher burnup technologies; and (4) a visual of critical milestones anticipated to maintain a mid-to-late 2020s batch loading deployment timeline for the entire suite of near-term ATF, increased enrichment, and higher burnup. This graphic has been updated to reflect critical milestones completed since the last revision was issued in January 2024.

The information presented does not supersede any regulations or guidance and the information presented should not be interpreted as new regulatory requirements or guidance. The future updates will be on an ongoing basis and evaluated biannually, through continued stakeholder engagements.
