In brief
Julia DeWahl argues that small nuclear reactors have a realistic first market in places that cannot tolerate power failures, especially the US military, which pays a premium for resilience and wants to escape its dependence on delivered diesel. Public opinion, bipartisan regulatory reform and demand from AI data centers have made this the best moment for nuclear in decades.
The central tension is between momentum and execution. Policy, public sentiment and government demand are all pointing the right way, yet a startup still has to prove its reactor works, raise hundreds of millions of dollars and survive a slow, expensive supply chain. DeWahl's answer is to start where customers are least cost-sensitive and let falling costs open civilian markets later.

Julia DeWahl joined SpaceX as Starlink moved from research and development into go-to-market, to lead that team and its business operations.
“I joined as Starlink was coming out of R &D and into go-to-market. That's why I was joining, to lead that team and the business operations there.”

After early Starlink customers described painful setup, SpaceX formed a cross-functional team to build mounting options sold alongside the Starlink dish.
“it led to basically this cross-functional SWAT team that was dedicated to mounting options to be sold alongside the dish.”

Antares's micro-reactors are below one megawatt, in the hundreds of kilowatts, enough for hundreds of houses.
“we're even sub one megawatt. We're kind of in the hundreds of kilowatt scale. You can think of that as like hundreds of houses worth of electricity.”

Antares plans a criticality test next year and a first demonstration unit by the end of 2027.
“next year, our criticality test is kind of the first milestone. By end of 2027, we want to have our first demonstration unit demonstrated.”

DeWahl said that about half of US casualties in Afghanistan were attributed to fuel and supply logistics.
“it was 50 % of the, I think the Afghanistan casualties were from just logistics.”

The US put a small nuclear reactor into space in the 1960s, and it worked for a few months.
“We actually put one reactor into space in the 1960s to test that out. Did it work? Yeah, for a bit. I mean, a few months.”

DeWahl said US support for nuclear power rose about 17 points in five to ten years, to over 60 percent.
“The like percentage point change we've seen in the last five to ten years is almost 20 points. I mean, it's like 17 points or something. So it's 60 plus percent of people support nuclear.”

DeWahl said Biden-era legislation changed the NRC's mandate so that it no longer focuses only on safety.
“they changed the mandate of the NRC. And they said, you are no longer focused just on safety because what's the safest number of nuclear reactors to license? Zero.”

The NRC regulates civilian power only, so Antares's military reactors can initially avoid NRC licensing.
“The NRC really only license, sorry, regulates civilian electricity, so civilian power. So we actually don't need to even go there yet.”

The 2022 Inflation Reduction Act introduced production tax credits for nuclear power.
“There's now production tax credits for nuclear, which has a lot of ripple effects.”

DeWahl said France deliberately moved to about 70 percent nuclear electricity in the 1970s because it lacked domestic fossil fuels.
“France made a very, very deliberate decision to actually go to 70%, if not more at the time in the 70s, because I had no carbon resources, right?”

DeWahl said only about 1 percent of uranium used in US nuclear fuel was recently mined domestically.
“it's been like 1 % of nuclear fuel used in the U .S. was actually domestically mined.”

DeWahl said the US still buys almost half of its uranium from Russia and former Soviet states.
“we're still buying like almost 50 % of our uranium from Russia and kind of ex-Soviet states.”

DeWahl met her co-founder Jordan after posting a piece on Twitter, and he had the vision of military micro-reactors.
“That's actually how I met Jordan, who's my co-founder. And he's the one who actually had the vision for micro-reactors for the military.”

NASA's Commercial Orbital Transportation Services program used fixed, milestone-based contracts rather than cost-plus contracts, per DeWahl.
“Commercial orbital transport system. Yeah, yeah, yeah. It was like the innovation basically to say, like, let's try something that's not cost plus.”
