Advanced Nuclear Tracker

The Advanced Nuclear Tracker is a directory of the companies developing new nuclear technology, from fission and fusion reactors to fuel supply, nuclear batteries and waste management. It covers 179 companies: 146 still private or venture-backed and 33 trading on public markets. Each record carries the technology, the country, disclosed funding to date, the executive team and recent headlines. The public names add delayed price, day change, market cap and 30-day and one-year price history.

The Map tab plots the global footprint: 174 geolocated companies across 22 countries, fanned around each national centroid and coloured by technology segment — fission, fusion, fuel cycle, isotopes. It shows where the new entrants are clustered, and how thin the field still is outside a handful of countries.

Who is in the tracker

Fission and fusion developers make up the largest groups. The rest work across the fuel cycle (uranium mining, conversion, enrichment and fuel fabrication), medical and industrial isotopes, nuclear propulsion, materials, engineering services, and waste and decommissioning. Many companies span more than one segment.

Just over half of the companies, 91 of 179, are headquartered in the United States. The United Kingdom and France have 13 each, followed by Japan, China, Canada, Germany and Sweden.
