Accident Tolerant Fuel Roadmap
The NRC's role with ATF is to review the new fuel technologies and their associated enrichment, fabrication, transportation, and storage aspects to ensure that they maintain public health and safety when implemented by NRC licensees.
The NRC reviews the technologies against all applicable guidance, available data, and past precedent applications to determine if the new fuel design continues to meet the NRC's regulations.
