After-Pop! Wait... Should We Recycle Used Nuclear Fuel? The History, Economics, and Proliferation concerns

<p><strong>Ed McGinnis</strong> said something in our last episode that&#39;s hard to shake: 96% of the energy in spent nuclear fuel has never been touched. The physics checks out. But what happens when countries actually try to get that energy back?</p><p>This After Pop digs into the history of nuclear fuel recycling, not the theory, but the track record. France, the UK, Japan. Staggering sums of money. Complicated results. And a 1977 executive order that changed everything.</p><p>We break down what PUREX actually does, why Jimmy Carter banned commercial reprocessing, and what any next-generation recycling technology (including Curio&#39;s NuCycle) would actually have to solve to change the equation.</p><ul><li><strong>France&#39;s La Hague plant:</strong> running since 1976, processing 1,000+ tons of spent fuel per year, and saving roughly 18,000 metric tons of natural uranium. Also: a Court of Auditors estimate ranging from €16 billion to €58 billion in total program costs.</li><li><strong>The UK&#39;s Sellafield THORP:</strong> built for £1.8 billion, promised £500 million in profit, delivered £1 billion in losses, closed in 2018. Decommissioning costs are estimated at up to £250 billion and won&#39;t be finished until 2125.</li><li><strong>Japan&#39;s Rokkasho:</strong> supposed to open in 1997. It&#39;s 2026. Construction costs have hit ¥3.7 trillion (~$25 billion), with lifecycle costs projected above $100 billion. It has never processed a full ton of commercial fuel at capacity.</li><li><strong>PUREX:</strong> what it actually does, why it was designed the way it was (Manhattan Project-era, weapons-grade plutonium), and why producing a pure stream of separated plutonium is the source of the proliferation problem.</li><li><strong>India&#39;s 1974 Smiling Buddha test:</strong> where Carter&#39;s concern came from, and why it wasn&#39;t theoretical.</li><li><strong>The five things next-gen recycling has to solve:</strong> cost, proliferation resistance, regulation, waste, and public trust.</li></ul><p><strong>The numbers that matter:</strong></p><ul><li>~$85/lb: current uranium spot price</li><li>~$140/lb (~$360/kg): the price at which reprocessing starts to break even, per Harvard&#39;s Belfer Center</li><li>99 metric tons: France&#39;s current separated civilian plutonium stockpile</li><li>44.4 metric tons: Japan&#39;s separated plutonium (most of it sitting in France and the UK)</li><li>300 years vs. 100,000+ years: radiotoxicity timeline for recycled waste vs. direct disposal</li></ul><p><strong>Resources:</strong></p><ul><li>Harvard Belfer Center, The Economics of Reprocessing vs. Direct Disposal of Spent Nuclear Fuel: <a href="https://www.belfercenter.org/publication/economics-reprocessing-vs-direct-disposal-spent-nuclear-fuel">https://www.belfercenter.org/publication/economics-reprocessing-vs-direct-disposal-spent-nuclear-fuel</a></li><li>France&#39;s Court of Auditors report on nuclear costs (English summary via World Nuclear Association): <a href="https://world-nuclear.org/information-library/nuclear-fuel-cycle/fuel-recycling/processing-of-used-nuclear-fuel">https://world-nuclear.org/information-library/nuclear-fuel-cycle/fuel-recycling/processing-of-used-nuclear-fuel</a></li><li>UK Nuclear Decommissioning Authority, Sellafield: <a href="https://www.gov.uk/government/organisations/nuclear-decommissioning-authority">https://www.gov.uk/government/organisations/nuclear-decommissioning-authority</a></li><li>Japan Atomic Energy Commission, Rokkasho lifecycle cost estimate: <a href="https://www.jaec.go.jp/en/">https://www.jaec.go.jp/en/</a></li><li>Jimmy Carter&#39;s Executive Order on Reprocessing (1977): <a href="https://www.nrc.gov/docs/ml1209/ML120960615.pdf">https://www.nrc.gov/docs/ml1209/ML120960615.pdf</a></li><li>IAEA, Proliferation resistance of nuclear fuel cycles: <a href="https://www.iaea.org/topics/nuclear-fuel-cycle">https://www.iaea.org/topics/nuclear-fuel-cycle</a></li></ul>
