When SpaceX decided to manufacture its own rocket engines, write its own flight software and build its own launch infrastructure, the aerospace industry called it inefficient. Why duplicate what established suppliers already did well?
A decade later, the answer is obvious. Vertical integration gave SpaceX something the traditional defense contractor model could not: the ability to iterate fast, test under real conditions and fix problems without waiting on a supplier’s schedule or a procurement cycle. Speed became a structural feature, not a project management achievement.
The team behind Applied Atomics lived that transformation from the inside. Now they are building the same way in nuclear.
The company’s founding team worked at SpaceX during its formative years, building the infrastructure and systems that proved the vertical integration thesis at scale. Collectively they have designed, delivered and operated billions of dollars of complex technical infrastructure the same way: own the stack, compress the feedback loops, build safety in rather than bolt it on.
They did not come to the nuclear power industry to apply a theory. They came to apply a method they have already proven.
The traditional nuclear deployment model and its limits
For most of the industry’s history, nuclear development has been a procurement and assembly exercise. Developers specify components. Suppliers manufacture them. Integrators bring the pieces together. Regulators review the result.
Each handoff introduces delay. Each delay introduces cost. Over time, those costs compound in ways that make the final number look nothing like the original estimate.
What vertical integration actually changes
Controlling more of your own stack does not mean doing more things poorly. It means reducing the distance between a problem and its solution.
When a developer owns the design, the manufacturing process and the operational knowledge base, a design question does not have to travel through three organizations before it gets answered. A materials issue does not require a contract amendment. A regulatory question about component performance can be answered with internal data rather than a supplier attestation.
That compression of feedback loops changes the pace of development in ways that schedules and budgets alone cannot capture.
Safer systems move faster
In nuclear development, safety and speed are not competing priorities. They are the same variable expressed differently.
A system designed with safety engineered into its architecture, rather than managed through procedural controls and external oversight layers, moves through regulatory review more predictably. Fewer design ambiguities mean fewer NRC questions. Fewer NRC questions mean fewer review cycles. Fewer review cycles mean a more reliable path to an in-service date.
Applied Atomics builds this way deliberately. The company’s nuclear power systems are designed for continuous operation and long service lives, with safety embedded at the component and systems level rather than added on top. The result is a development process that does not treat regulatory engagement as an obstacle to manage but as a validation process the design is built to pass.
That is not a compliance posture. It is an engineering posture. And it moves faster.
What utilities should watch for
Vertical integration is a meaningful differentiator between nuclear companies today. The question is not just what a developer is building but how much of that process they actually control.
A developer who owns their design, their manufacturing relationships and their operational knowledge base is a developer who can answer hard questions quickly, absorb changes without cascading delays and deliver on timelines with genuine confidence rather than optimistic projection.
The SpaceX parallel is instructive not because nuclear is like rocketry but because the underlying dynamic is the same: When you control your stack, you control your schedule. When you control your schedule, you control your cost. And when safety is built into the architecture, you do not slow down to accommodate it. It accelerates you.
That is the model nuclear has been waiting for.
