State Nuclear Policy Map
Where each US state stands on nuclear energy — the legal barriers that remain, the legislation moving, the incentives on offer, and what is actually being built. Researched July 2026.
Click any state for the full policy picture.
Posture bands are Nucleation Capital's judgement, not a computed index; every state carries its reasoning and its sources so you can disagree with the call. Legal status is the objective layer and is the better thing to rely on. Eleven states still gate new construction: CA, CT, HI, ME, MA, MN, NJ, NY, OR, RI, VT. Minnesota's is an outright statutory ban; New York's binds only LIPA on Long Island; Connecticut's can be lifted town by town, but only for advanced reactors; New Jersey's April 2026 law relaxed its condition rather than removing it. Statutory claims were verified against primary sources in July 2026. This page is informational and is not investment, legal or policy advice.
The rest of the world
Every country's nuclear programme — operating fleet, capacity, share of electricity, what is under construction, which vendors are winning, and where policy is heading. Reactor figures from IAEA PRIS.

Reactor counts, capacity and share of electricity come from IAEA PRIS, the authoritative register. PRIS lags reality in known ways and these have not been silently corrected: reactors mid-restart remain classified as permanently shut down, which is why the United States shows 94 operating and zero under construction despite an active build pipeline, and Japan's restarted units move across slowly. Those cases are flagged in each country's notes. Status and direction are Nucleation Capital's judgement, with reasoning and sources on every country. Countries in grey have no civil nuclear programme. Informational only; not investment advice.
