Building a Rad Future

This episode covers a critical re-evaluation of the current nuclear energy renaissance, featuring prominent advocates Isabelle Boemeke and Madison Hilly who argue the industry needs a reality check to separate hype from viable solutions.
There are four key takeaways from their discussion on the future of nuclear power.
First, the industry must avoid the trap of prioritizing exotic innovation over proven execution. The conversation challenges the popular Silicon Valley narrative that small, modular, and novel reactor designs are the only path forward. This obsession with novelty risks derailing the industry's recovery. Instead, the speakers advocate for boring nuclear energy, specifically large, proven light-water reactors, as the only currently scalable solution to climate change.
Second, applying the SpaceX model to nuclear energy is a dangerous fallacy. There is a fundamental misunderstanding in applying software or aerospace development cycles to nuclear power. Unlike rocketry, where iteration can happen relatively cheaply, a nuclear prototype costs billions and takes a decade to test. The move fast and break things methodology fails when breaking things implies radiation risks and catastrophic financial losses.
Third, Western nations risk falling behind due to a lack of industrial competence, not a lack of new technology. While the U.S. chases hundreds of startups with unproven designs, China is successfully deploying standard, gigawatt-scale light-water reactors based on established technology. This divergence proves that the barrier to nuclear expansion is not regulatory or technological, but rather a failure to commit to building established designs at scale.
Finally, the most immediate priority must be the preservation of existing infrastructure. Before banking on future technology, policy must focus on extending the life of every currently operating nuclear plant. Keeping a gigawatt-scale plant open is argued to be the single most effective climate action available today, far outweighing the speculative promise of paper reactors that exist only in digital simulations.
In summary, the nuclear sector must undergo a pragmatic exorcism of unproven hype and refocus on the construction mastery of existing designs to avoid squandering what may be its last chance for a renaissance in the West.
Episode Overview
- Re-evaluating the "Nuclear Renaissance": Two prominent nuclear advocates, Isabelle Boemeke and Madison Hilly, discuss why they feel uneasy about the current hype surrounding the nuclear industry, suggesting the sector needs a "nuclear exorcism" to separate reality from wishful thinking.
- The Danger of Exotic Tech: The conversation challenges the popular Silicon Valley-style narrative that small, modular, and exotic reactor designs are the only path forward, arguing that this obsession with novelty risks derailing the industry's recovery.
- Pragmatism over Innovation: The speakers make a case for "boring" nuclear energy—specifically large, proven light-water reactors—as the only scalable solution to climate change, contrasting Western stagnation with China’s successful deployment of standard technology.
Key Concepts
- The "Last Renaissance" Risk: The speakers argue that the West is currently in its "third nuclear renaissance," and if this one fails due to over-promising and under-delivering, the industry may never recover in Western nations. The stakes are existential for the technology in democratic countries.
- The SpaceX Fallacy in Nuclear: There is a fundamental misunderstanding in applying software or aerospace development models to nuclear energy. unlike SpaceX, which can iterate rockets for millions, a nuclear prototype costs billions and takes a decade to test. The "move fast and break things" model does not work when "breaking things" implies radiation risks and billion-dollar losses.
- Innovation vs. Execution: The industry suffers from a fixation on design innovation (new types of reactors) rather than construction execution. The speakers point out that concepts like "small modular reactors" (SMRs) have been pitched since the 1980s without success. Real progress comes from mastering the construction of existing, proven designs.
- The China Reality Check: While the U.S. chases 100 different startups with unproven designs, China is rapidly deploying standard, gigawatt-scale light-water reactors (often based on Western technology). They are proving that the barrier to nuclear is not a lack of new technology, but a lack of industrial competence and commitment to building established designs.
- The Regulatory Scapegoat: While the Nuclear Regulatory Commission (NRC) is often blamed for the industry's stagnation, the speakers argue this is a distraction. The real issue is that startups often lack mature products to license, and the industry has failed to manage construction costs effectively, independent of regulation.
Quotes
- At 1:58 - "What we actually need is a nuclear exorcism... people are too excited about nuclear." - Explaining the central thesis that uncritical hype creates a bubble of expectation that the slow-moving nuclear industry cannot meet, setting it up for failure.
- At 8:39 - "How is it possible that people think it's going to be easier to replace this one nuclear power plant's output with renewables than to just keep it open?" - Highlighting the logical disconnect in energy policy where building massive new infrastructure is viewed as "easier" than maintaining existing, functional clean energy assets.
- At 14:00 - "These enhanced safety features combined with the small size of the modular reactor will allow us to take full advantage of the higher productivity of factory production... This was written 41 years ago by GE." - Demonstrating that the current "revolutionary" promises of Small Modular Reactors (SMRs) are actually recycled ideas that failed to materialize decades ago.
- At 17:42 - "SpaceX could build rockets for a couple million dollars... With nuclear it takes hundreds of millions of dollars to be able to build one reactor... It can't be a distraction." - Clarifying why the Silicon Valley startup model is structurally incompatible with the capital intensity and safety requirements of nuclear energy development.
Takeaways
- Prioritize the "Low Hanging Fruit" of Existing Plants: Before banking on future technology, advocacy and policy must focus on extending the life of every currently operating nuclear plant. Keeping a gigawatt-scale plant open is the single most effective climate action available today.
- Focus on Proven Tech for Grid-Scale Power: When evaluating energy solutions for immediate grid decarbonization, deprioritize "paper reactors" (designs that exist only in digital simulations). Focus investment and policy support on building large, standard light-water reactors that have a track record of operation.
- Be Skeptical of the "Module" Narrative: When presented with claims about factory-built, modular nuclear reactors solving cost issues, recognize this is a historical promise that has historically failed due to the complexities of nuclear physics and regulation. Look for prototypes, not just pitch decks.
