I have to throw a little water on the "clean" part of the claim, unfortunately. JET does deuterium/tritium fusion, which produces neutron radiation that causes the lining of the reactor to become radioactive. The lining needs to be replaced every once in a while, producing nuclear waste.
While true, that is misleading. The nuclear waste produced will be radioactive for some decades, in contrast to the waste products from nuclear fission, which stay radioactive virtually forever. Most people think of fission waste if you don't specify and thus make fusion waste far scarier than it actually is.
