Apollo Atomics: The Modern Nuclear Company
Hey everyone 👋
We're Assil and Drew — co-founders of Apollo Atomics.
TL;DR
Apollo Atomics took the pressurized water reactor technology that already powers 80% of the world's nuclear plants and flipped one part, the steam generator, to make the plant an order of magnitude smaller without compromising power. That single change turns a decade-long construction project into a factory-built machine that fits on a truck. We've built a working demonstrator, tested it, and our fuel is already critical before July 4th.
We put the whole story into just over two minutes — it's the clearest version of what we're building we've made so far: ▶️ <https://youtu.be/vy8y_t1KAK4?si=FmGF4Q7w6eFkn4No>
The Problem
The existing nuclear playbook doesn't work for customers who need power now.
- Gigawatt-scale nuclear takes 10+ years and \~$20B per plant.
- Most Small Modular Reactors (SMRs) in development rely on exotic fuels, unproven coolants, or supply chains that don't exist yet.
- Customers who need power in 2030 are being told to wait until 2035+ and hope.
Data centers, industrials, and utilities have demand today — and no credible nuclear option that can ship on their timeline.
Our Solution
Apollo builds compact pressurized water reactors — the same technology that runs \~80% of the world's nuclear plants today. The difference is that our reactor is roughly 40x more compact, because we shrank only one component: the steam generator.
We keep everything the NRC has already licensed dozens of times — light water, low-enriched uranium, fuel, and components from existing qualified supply chains. The innovation is a single part: the steam generator.
Our Compact Steam Generator (CSG) replaces the massive, hand-built steam generator at the heart of a conventional PWR with a component 20x smaller, delivering the same thermal power — pre-tested, transportable, and contracted at a fixed price. That one change is what takes a reactor from a decade-long construction project to a factory-built machine deployable in less than 24 months.
Our product roadmap is three reactors, each on a truck, each for a different customer segment:
- A-10 — 10 MWe
- A-50 — 50 MWe
- A-300 — 300 MWe
Our Ask
If any of these are you, we'd love to talk:
- Data center operators and hyperscalers sourcing 24/7 firm power for 2028–2035 deployment.
- Industrial offtakers (chemicals, refining, heavy manufacturing) needing process heat or behind-the-meter electricity.
- Utilities evaluating SMRs for grid-connected generation.
