Safety

Safety built into the physics.

Built into every part of the design, which also removes refueling, fuel handling and spent-fuel systems.

Full-scale prototype, non-fueled

AMPERA's full-scale, non-fueled nuclear reactor module prototype
01

Subcritical by design

Normal operation is subcritical, sustained by an integrated neutron source. Remove the source and the reaction stops.

02

Walk-away safe

A walk-away safety design with passive emergency cooling.

03

Compact by design

Designed for containerized deployment. No reliance on control rod motion during operation, a minimal shutdown absorber system, and reduced vessel height and penetrations make a fundamentally smaller reactor.

04

Safeguards by design

Natural thorium needs no enrichment, reduces safeguard requirements and minimizes proliferation risk.

Command center

Every unit, watched in real time.

A command center monitors and controls every deployed unit for performance and rapid response.

Regulatory path

Engaging the NRC early.

On October 5, 2026, AMPERA submitted a Regulatory Engagement Plan to the U.S. Nuclear Regulatory Commission in the pre-application phase. It expects to file its combined manufacturing and fuel fabrication facility license application by October 2027.
