For forty years, nuclear power was a stranded asset in American energy policy — expensive to build, politically toxic after Three Mile Island and Chernobyl, and undercut by cheap natural gas. That era is ending. A convergence of forces has put Washington firmly behind nuclear: AI data centers are devouring electricity faster than the grid can supply it, the Pentagon wants energy-independent bases, and both parties have found common ground in the idea that zero-carbon baseload power is a national security asset. The result is a rare, durable policy tailwind that cuts across multiple federal agencies — the Department of Energy, the Nuclear Regulatory Commission, the Department of Defense, and the IRS — all moving in the same direction at the same time.
The policy mechanisms are specific and consequential. The Inflation Reduction Act created a production tax credit for existing nuclear plants, making previously marginal reactors economically viable again. Congress funded a domestic uranium enrichment restart to break reliance on Russian-supplied HALEU (high-assay low-enriched uranium). The NRC's ADVANCE Act accelerated licensing timelines for advanced reactor designs. The Department of Defense is running microreactor programs for forward operating bases. And Big Tech — Microsoft, Google, Amazon — has signed direct power purchase agreements with nuclear operators to feed AI infrastructure, turning utilities into growth companies overnight.
Understanding this playbook means understanding a supply chain, not just a single ticker. Uranium miners sit at the base; enrichers and fuel fabricators sit above them; reactor vendors and engineering firms sit above that; and utilities and power producers sit at the top, closest to the actual electrons. Policy moves at each layer differently, on different timelines, and creates different risk profiles. A reader who can map Washington's actions to the right layer of the stack will spot the trades before they become obvious.
