Contact Congress about H.R. 2504: The U.S.-European Nuclear Energy Cooperation Act of 2025

The State Department would have to write a plan for expanding U.S.-European nuclear energy work. The goal is to help Europe rely less on Russian and Chinese nuclear technology, fuel, and influence. The bill would also allow $30 million a year for related work from 2025 through 2029.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

The U.S.-European Nuclear Energy Cooperation Act of 2025 is a House bill in committee. The latest recorded action: Ordered to be Reported in the Nature of a Substitute by the Yeas and Nays: 43 - 3.

Latest action on H.R. 2504: Ordered to be Reported in the Nature of a Substitute by the Yeas and Nays: 43 - 3.

Who this affects: This bill mainly affects European countries that have nuclear power programs or may build them. It also affects U.S. and allied nuclear companies that want to sell reactors, fuel, or services in Europe. U.S. agencies would have to plan and coordinate this work. Russia, China, and Rosatom could be affected because the bill aims to reduce their role in Europe’s nuclear sector.

Why this matters: Europe’s nuclear choices can affect energy security and how much leverage Russia has over European countries. Many nuclear systems depend on long-term technology, fuel, and service contracts. This bill would push the United States to plan for a bigger role in those choices. It could also shape clean energy plans, but the bill does not directly decide how much nuclear power Europe will use.

Key provisions in H.R. 2504

  • The Secretary of State must write a plan for U.S.-European nuclear energy cooperation. The Secretary of Energy and other agencies must help shape it.
  • The plan must explain how more U.S. nuclear companies can work in Europe. It must also show how they can better compete with Russian and Chinese nuclear technology.
  • The plan must study the reactor types Europe uses or is considering. It must explain how each type could reduce Russian influence by 2030, 2035, 2040, 2045, and 2050.
  • The plan must identify what makes each reactor type hard to deploy. That includes high costs, market barriers, supply chain limits, and government approval rules.
  • The plan must review Europe’s nuclear fuel supply chain. It must cover low enriched uranium and high assay low enriched uranium, and how fuel choices could cut Russia’s share of uranium, conversion, enrichment, and fuel markets by 2030.
