Q. Are there any other tokamaks in operation around the world?
A. There are many tokamaks in operation around the world, all contributing to international efforts to realise commercial fusion power. As well as JET, the other tokamaks in Europe, which are part of the EUROfusion agreement include ASDEX -Upgrade, MAST-Upgrade, TCV, and WEST.
There are also tokamaks operating in the USA and Japan, and smaller tokamak experiments all over the world (in countries such as Brazil, India, Australia, China, Russia etc.)
Nick Balshaw, researcher at JET, has put together a website with information about all the tokamaks in the world. Have a look: All the World’s Tokamaks. And Joanne Flanagan, also a JET researcher, has created a map that shows the location of the tokamaks.
