Oklo’s Caroline DeWitte on powering the world using spent nuclear fuel rods
Caroline DeWitte is the co-founder and COO of Oklo, a company building advanced nuclear power plants designed to deliver clean, reliable energy at smaller scale. Her core belief is that nuclear energy is not a legacy technology to tolerate, but a modern infrastructure solution to expand. In this conversation, she explains why the real barrier to nuclear progress has often been business model design, regulatory approach, and industry stagnation rather than technical possibility. The central takeaway is clear: advanced nuclear can become commercially viable when leaders redesign the system around safety by design, manufacturability, and serious customer demand.

The need-to-know:
The constraint is not always the technology. In frontier industries, adoption often stalls because the commercial model, delivery model, and regulatory strategy have not evolved with the science.
Regulators are not a hurdle to manage around. Companies that treat regulators as serious partners in public trust can create faster, stronger pathways to market.
Scale comes from repeatability, not ambition alone. Oklo’s advantage is not just reactor design, but a system built for standardisation, faster licensing, and manufacturable deployment.
Let’s go a little further
There is a familiar mistake leaders make when they look at legacy industries. They assume the technology is old, so the opportunity must be old too.
Caroline DeWitte offers a more useful frame. Nuclear energy has been with us for decades, but its strategic potential is being rediscovered in a new context. The pressures are different now. Energy demand is rising. AI infrastructure is accelerating power consumption. Climate commitments are tightening. Land use matters more. Reliability matters more. In that environment, advanced nuclear starts to look less like a controversial edge case and more like an obvious missing piece.
What makes Caroline’s perspective especially valuable is that she does not reduce the challenge to engineering alone. Oklo’s thesis is not simply that there is a better reactor. It is that the industry has been trapped inside an outdated model. Large plants, sold to large utilities, with long timelines and little flexibility, made sense in an earlier era. They make less sense in a world that increasingly values distributed infrastructure, speed, and customer-specific energy solutions.
That distinction matters for any CEO building in a regulated market. Many companies over-focus on technical novelty and under-focus on system design. Caroline’s point is more strategic: markets do not reward invention in isolation. They reward invention that can be financed, licensed, delivered, and repeated.
Her comments on regulation are particularly strong. She avoids the lazy framing that regulators are the villain in the story. Instead, she points to a harder truth. In her view, parts of the nuclear industry became complacent, slow, and resistant to modernisation. That is a leadership failure, not a regulatory one.
This is where the conversation becomes relevant far beyond energy. In sectors like biotech, health, defence, fintech, and infrastructure, leaders often treat regulation as an obstacle course. Caroline describes a more effective posture. Meet the standard. Respect the mandate. Help define the right process for a new category without assuming the regulator is the enemy.
That is not softness. It is strategic maturity.
Oklo’s approach reflects that mindset. The company has spent years working through how a new class of reactor can fit within existing public safety expectations while also proving a different commercial pathway. Smaller reactors. Safety by design. Reduced land footprint. Standardised components. The ability to reuse fuel that conventional systems have left behind. The ambition is large, but the logic is disciplined.
There is also a deeper leadership lesson in how Caroline talks about scale. She does not describe success as building a single impressive asset. She describes it as building a system that can be reproduced many times. That is a critical distinction. One successful project can win attention. Only repeatable execution changes an industry.
This is why her comments on partnerships are so useful. Whether she is discussing suppliers like Siemens or future energy buyers such as data centres, her lens is readiness. Not interest or headlines. Readiness. Who is willing to commit resources, align on timelines, and engage with the real constraints of deployment.
That is how serious partnerships are built in complex markets. Through shared intent, practical commitment, and clarity about the road ahead.
The broader implication is hard to ignore. Advanced nuclear may become one of the defining infrastructure categories of the next decade, not because the science suddenly appeared, but because commercial urgency has caught up with technical possibility.
For CEOs, that is the real invitation here. Look again at industries you assume are fixed. Often the breakthrough does not come from a brand-new invention. It comes from rethinking the model that surrounds it.
Question for you
Where in your business are you trying to force new potential through an old system?
When you're ready, there are two ways I can help you:
1. CEO Coaching: For CEOs and soon-to-be CEOs who want to lead with clarity and grow their business without sacrificing what matters most. A tailored 12-session experience with three interconnected elements: scaling you as a leader, elevating how you lead others, and creating conditions for sustainable business growth.
2. Leadership Events: What if your leaders left the room thinking differently about ambition and their role in achieving it? I've worked with military special operations leaders and leadership teams at Cochlear and Lifeblood where poor leadership costs lives. Looking for real stories, frameworks and insights that shift how leaders think about ambition, create leverage and build teams worth following? Book me for your next conference, offsite, or leadership event.
