Roughly 20% of the U.S. power grid runs on nuclear energy. A quarter of the fuel behind it is headed toward a hard stop. In this episode, I sit down with Scott Nolan, founder and CEO of General Matter, to unpack why uranium enrichment has quietly become one of the most consequential industrial bottlenecks of the 21st century. While at Founders Fund, Scott spent over a year searching for an American enrichment company to back. When he couldn’t find one, he decided to build it himself. Less than a year after emerging from stealth, General Matter secured a historic enrichment site in Paducah, Kentucky, and was awarded a $900 million Department of Energy contract—marking one of the first serious efforts to rebuild domestic enrichment capacity ahead of the 2028 ban on Russian supply.

In this episode, we discuss:

• Why enrichment is the missing link in America’s nuclear supply chain

• How the U.S. went from controlling 86% of global enrichment capacity to effectively none at commercial scale

• The science behind uranium enrichment and why it matters for next-generation reactors

• Why Scott applied the SpaceX playbook to nuclear after more than a decade in venture capital

• How General Matter is revitalizing the historic Paducah, Kentucky enrichment site

• The significance of General Matter’s $900 million Department of Energy contract

• The bipartisan political support for expanding nuclear energy

• Why Scott believes nuclear energy could grow 3-4x by 2050

• The parallels between America’s space and nuclear industries
