The @USArmy has awarded Radiant $750 million to deliver 15 Kaleidos microreactors through the Janus program, one of the largest contracts @DIU_x has issued to date.
The Army launched the Janus Program to strengthen the energy resilience of military installations and mission-critical infrastructure. Radiant was chosen after extensive evaluation of reactor design, technical maturity, manufacturing readiness, deployment strategy, and commercial viability. Radiant’s 15 microreactors will enable the Army to deploy nuclear power across multiple locations. In tandem, the operational data acquired through the Program will accelerate commercial deployments across a global footprint of commercial customers.

Top of mind for us at Climate Week NYC: the power gap. Our CFO, Ale Palma, joined leaders from @BCapitalGroup, @Orrick, and @StarCatcherInd to discuss what it will take to close it and how Radiant is working toward that today.
As Ale put it, moments like these help the industry and investors separate signal from noise and understand what really matters in this nuclear renaissance.

Today, we're announcing a long-term partnership with @centrus_energy to supply HALEU for our Kaleidos fleet, adding another domestic source of fuel to support our commercial and military deployments.
Scaling advanced nuclear takes fuel, manufacturing capacity, and a supplier ecosystem that can move with you. We have all three.

Our Chief Nuclear Officer @RitaB66 took a minute to grab a selfie with attendees at our Oak Ridge event - because moments like this are meant to be shared with the community. Thank you to the @ORChamber and everyone who joined us to learn about our R-50 manufacturing facility and the future of energy!

Kaleidos is making history. The @INL DOME hasn't hosted a new reactor design test since EBR-II shut down in the 1990s. That's roughly 30 years without this kind of hands-on, full-power testing & validation of new nuclear technology on U.S. soil. That changes today.
Radiant earned this spot through a competitive DOE down-select, evaluated on design maturity and execution readiness against the rest of the field. We were assessed as the most mature company in the space, and we now hold exclusive use of DOME for full-scale, full temperature commercial testing.
Proud doesn't quite cover it. @NRICnuclear Let's get to work!

The uranium in our Kaleidos reactor is a "child of the stars", forged by neutron stars formed in the milky way... which you can see here, on our way to the @INL DOME.

The road to @INL DOME – we were chosen for the maturity of our product and our path to commercialization.
When we were selected for the DOME, it was a competitive process that pitted us against 40+ companies. We competed 3 times. FEEED, DEED, and final selection. We were chosen for the maturity of our product and our path to commercialization. That vision we build for at Radiant is not on the horizon, it’s driving down the 395. Kaleidos is transportable and on the way to the DOME!

Kaleidos has left the building!
Our transportable microreactor is on its way to @INL's DOME facility, where it will begin full-scale testing.
Over the coming months, we'll validate commercial performance through a full-scale, full-power extended-duration testing program that progresses in 5 phases:
-Install and fuel Kaleidos
-Reach zero-power criticality
-Sustain 1MW thermal operation
-Full-temperature and full-power operation
-150-hours continuous operation
In 2020, our CEO @DougBernauer said we’d have a reactor at the DOME in 2026 - and we will!
