About Antares Nuclear
Antares Nuclear is a US-based advanced nuclear company developing solid-state, sodium-cooled high-temperature microreactors. The Mark-0 zero-power test reactor and the planned Antares R1 (100 kW-1 MW) use TRISO fuel and liquid-sodium heat pipes designed to passively cool the core. The company is the first participant in the DOE's Reactor Pilot Program to reach criticality and has been selected for installation at Joint Base San Antonio by 2028.
