In this light, in 1987 the Community, Japan, the USA and USSR jointly decided to cooperate in this area, through the ITER project which brings together all four major fusion programmes as equal partners in the conceptual design of an engineering test reactor (*) A tokamak is a ring-form construction inside which fusion reactions are confined which liberate temperatures of several millions degrees centigrade.
