Thermonuclear fusion will allow an endless energy source that is safe and clean because, unlike traditional nuclear fission reactors, there is no radioactive waste at the end. Traditional nuclear reactors split atoms to create energy and therefore produce dangerous radioactive waste while thermonuclear fusion compresses atoms at extremely high temperatures to generate energy and generate little waste matter.
There is a parallel global consortium called the International Thermonuclear Experimental Reactor (ITER) which includes US, EU, Russia , China , Japan , South Korea , and India . India already has 2 experimental reactors
Aditya and SST-1 run by the Institute of Plasma Research and was invited to join the
Global Nuclear Energy Partnership by the US. India collaborated with the Center for Nuclear Research (CERN) large hadron collider project with indigenously designed and developed equipment
