Conventional reactors use only 5% of their fuel. Oklo's technology recycles the remaining 95%, transforming the nation's nuclear "waste"—a massive liability—into an energy asset with more potential energy than Saudi Arabia's oil reserves.

For new nuclear tech, competing with cheap solar on cost is a losing battle. The winning strategy is targeting "premium power" customers—like the military or hyperscalers—who have mission-critical needs for 24/7 clean, reliable energy and are willing to pay above market rates. This creates a viable beachhead market.

Today's nuclear energy boom is propelled by strong commercial demand from AI data centers and defense, not government R&D. This market-driven "demand pull" for energy is finally creating the business case for advanced and small modular reactors.

Radically departing from the traditional model of massive, on-site construction, Radiant is designing portable micro-reactors to be mass-produced in a factory. This "reactor as a product" approach aims to deliver power solutions that can be shipped and activated in 48 hours.

AI hyperscalers' urgent need for power makes them willing to pay a premium for rapid deployment (months vs. years). This high-margin initial market can fund the transition to factory-based mass production for nuclear energy, eventually allowing costs to drop for broader markets like utilities and industrial users.

Oklo vertically integrates by designing, building, and operating its reactors. Customers simply sign long-term power purchase agreements, which removes the immense capital risk and operational complexity of constructing their own nuclear facility.

The idea for Radiant's portable nuclear micro-reactors originated from a practical problem at SpaceX: how to generate megawatts of power on Mars to create fuel from ice. Solar power was insufficient, leading Elon Musk to suggest exploring nuclear, which ultimately inspired the founder's new company.

The biggest bottlenecks for the nuclear sector aren't just reactor design. The industry needs a competitive, free market for nuclear fuel and enrichment, along with a centralized national repository for waste. Solving these systemic issues is a prerequisite for startups and the broader industry to thrive.

Nuclear startup Antares is focusing on defense and space applications, what it calls "strategic energy." These are markets where nuclear's unique characteristics—high uptime and a minimal supply chain—provide value that alternatives can't match, allowing them to bypass direct competition with cheaper energy sources on the main grid.
