Antares Industries specializes in the development and deployment of advanced microreactors designed for both terrestrial and space applications. Their flagship product, the Antares R1, is a military-grade, rapidly deployable microreactor that provides continuous energy without the need for a sustaining supply chain for up to three years. The R1 reactor is engineered for transportability, resilience, and autonomy, fitting on standard military cargo platforms such as 463L pallets or CONEX containers. It features advanced shielding materials like tungsten, titanium carbide, and boron carbide to minimize exclusion zones and expedite deployment. The reactor employs sodium heat pipes for passive and redundant heat removal, ensuring high reliability without moving parts. Automated control systems and boron carbide shutdown rods, derived from space reactor technology, manage reactivity. The core utilizes HALEU TRISO fuel and a graphite moderator, encapsulating each fuel particle in silicon carbide for enhanced safety. The low-pressure closed nitrogen Brayton cycle further maximizes reliability and minimizes maintenance, making the R1 suitable for austere and remote environments. Antares Industries serves military and space agencies, offering a robust energy solution that operates autonomously with minimal specialized workforce requirements.
