Today, Valar Atomics became the first startup in history to split the atom.
Announcing Project Nova, a series of zero power critical tests on Valar Atomics' Nova Core in collaboration with Los Alamos NCERC and NNSS.
Nova went critical for the first time this morning at 11:45am.
The Nova core is a subset of our Ward250 core, using the same moderator, fuel, and reactivity control. Taking Nova critical gives us real-world data about the characteristics of our geometry and control scheme, and allows us to test our models and simulations against reality.
We're grateful for the close partnership of Los Alamos National Laboratory (LANL), the National Criticality Experiments Research Center (NCERC) and the Nevada National Security Site (NNSS), which all do extremely important work to maintain our nation's nuclear capabilities.
Today is a historic day for nuclear and for Valar Atomics.
But it's only the beginning. The President has ordered 3 advanced reactors on American soil by July 4th. Making power in Ward250 remains our goal for the Pilot Program, and Nova gives us the data we need to move quickly.
I am once again humbled to be working with the Valar Atomics team. This is the smartest, hardest working, and most motivated group of people I have ever had the pleasure of working with. I have seen them perform miracles.
Together, this team will make the world's energy cheaper.
Today we're announcing Valar Atomics' $130m Series A, led by Doug Philippone at Snowpoint Ventures and co-lead by Day One and Dream.
Also joining Team Valar are Balerion, Contrary, DTX, Alumni, Crosscut, Triplepoint, Palmer Luckey, Shyam Sankar, and more great funds and angels.
Doug Philippone brings decades of experience as an investor and operator, from Army Rangers and JSOC Commander to Head of Global Defense at Palantir, and most recently co-founder and GP at Snowpoint.
We're thrilled to welcome Doug to our board of directors.
The Valar Team is executing at an unprecedented rate, with several big announcements later this week. We're grateful that our previous leads, Riot Ventures, Initialized Capital, and AlleyCorp, have doubled down and deepened our existing partnerships.
Valar Atomics is honored to announce that we've been selected by the Department of Energy to achieve criticality on American soil by July 4th, 2026, pursuant to Executive Order 14301.
We're grateful to President Trump and Secretary Wright for their leadership in this matter. 1/x
Today, America embarks on a second Manhattan Project. This time, we seek to unlock the atom for energy, intelligence, and industrial might. But we must work with the same fervor and tenacity as our forebears to accomplish the President’s ambitious goal.
America faces a great challenge. For 40 years, we underinvested in energy and exported our energy-intense industries to other places.
The challenge today is to bring these industries back, while at the same time winning an energy-hungry race in AI.
Today, President Trump established a new policy for nuclear energy which represents a fundamental shift from the last 45 years of stagnation. This shift is codified in four executive orders.
Let's dig in!
First the history. The United States was once the undisputed leader in atomic energy. We created the world’s first reactor, and piloted every major reactor architecture since, from LWRs to to molten salt to my own favorite, the HTGR.
But two things happened in the 1970s which stopped us in our tracks. The first was India's development of the nuclear bomb from a US-provided civilian reactor. The second was Three Mile Island. American nuclear energy screeched to a halt.
It took about 10 years to get to Valar Atomics. I began pursuing this question in earnest when I was 14. In 2 years I had an idea of the problem, which I still believe. But it took 8 more years to build an accurate mental model of the industry and of reality, then find a solution
1. Describe my mental model in writing 2. Make specific predictions about what I expect to find in reality 2. Spend a few months Googling, reading, and talking to people with experience 3. Figure out why my predictions were wrong 4. Repeat
I had a to learn a lot of general things too—I started 2 companies and a family, worked on some hard projects.
Around 5 yrs ago I noticed that my predictions were getting very accurate. Prices, timelines, political decisions, tech stacks.
This morning Samo Burja went on a podcast with some very hard words for nuclear energy. I want address them immediately. But not because he's wrong.
Instead, because he got a few CRUCIAL things right; and the hard truths he tells go to the core of why I started Valar Atomics.
Burja argues two things:
1. Energy demand is unexpectedly low. 2. In order to make anything cheap, you need to make thousands of it. Nuclear is too powerful and energy demand too anemic to justify thousands of reactors. There's no market!
(he's right; I'll get to that shortly)
First, what he gets right: energy consumption in the US and much of the western world has flatlined in the last 20 years, after tepid growth since 1970. And in the same time, the inflation-adjusted price of energy has stagnated or risen.
Valar is my master plan to make energy 10x cheaper in 10 years by pulling oil and gas out of thin air with nuclear fission.
This will untether energy from climate and politics, fuel American industry, and unlock a new era of growth
All of our greatest ambitions — interplanetary life, artificial intelligence, robotics, and biotech — need energy that is orders of magnitude cheaper and more abundant than we have now.
In 1970 we stopped our century-long march of making energy cheaper.
I'm here to restart it.
Today, the vast majority of our energy comes from oil and gas. So if you want cheaper energy, the most direct way to get that is to make oil and gas much cheaper! ⛽️
And the cheapest way that I know to get oil and gas is to pull it out of thin air. 💨
