Nuclear energy is one of the most underinvested areas relative to its potential, and I’m thrilled that Alt Capital is leading Antares’s Series A. Fission is one of the most promising sources of energy we have at our disposal, and the 100-300kW micro reactors Antares is building

2024 has been an incredible year for Antares! Since Jan of 2024, we've 5x'd our headcount, contract value, and total capital raised. Come join us in 2025 as we >20x our manufacturing footprint and hit major hardware milestones!

Hope you got out today ✌🏻

👀🇺🇸⚛️

We do too 🫡

Fun celebrating our factory opening last night! We're building microreactors for earth & space -- if you're interested in joining us for the adventure of a lifetime, check out our open roles and reach out! jobs.ashbyhq.com/Antares

A great listen on all things nuclear with our founder & CEO Jordan Bramble 🎧

The U.S. Department of U.S. Department of Energy has selected Antares for its Nuclear Reactor Pilot Program, one of 11 projects fast-tracking advanced test reactors to deployment. energy.gov/articles/depar…

Let the hardware speak for itself

The U.S. Department of U.S. Department of Energy has allocated HALEU to Antares, fuel that will support our advanced microreactor as we move toward criticality. Another step toward delivering reliable fission power where it matters most.

This week, our team joined the Ohio Space Forum at NASA Glenn. An important step toward unlocking the future of space nuclear systems and a multi-billion-dollar industry.

Paper reactors don’t power missions. Tested hardware does. This week we demonstrated the startup of a high-output heat pipe. Delivering critical data just two days after completion. Full video on LI

We believe you have to build a reactor to design a reactor. This is the first of several electrically heated prototypes we’re constructing. Each one designed to validate critical aspects of our system.

Exotic material and turbo pumps require long, costly iteration cycles. We use heat pipes to move heat from the core to our heat exchanger. This choice means higher reliability, fewer single points of failure, and a reactor architecture that's durable in extreme conditions.
