India too has Tokamaks and they are located at Institute for Plasma Research at Ahmedabad. The best nuclear fusion reactor has been the Wendelstein 7-X (W 7-X)stellerator having produced the longest stable plasma.
Replying to @malay11 's comment, Yes it is a fission reactor, but the statement that it has zero nuclear waste is false. They have nuclear waste, but being Thorium232 and the plant using a fast breeder reactor, it is highly efficient and it has much less radioactive waste.
