Are tokamaks safe?

The results show that fusion can be a very safe and sustainable energy source. A fusion power plant possesses not only intrinsic advantages with respect to safety compared to other sources of energy, but also a negligible long term impact on the environment provided certain precautions are taken in its design.

Has fusion been achieved?

Steady progress has been made since in fusion devices around the world. The Tore Supra tokamak in France holds the record for the longest plasma duration time of any tokamak: 6 minutes and 30 seconds. US fusion installations have reached temperatures of several hundred million degrees Celsius. Why fusion is impossible on Earth? Normally, fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur.

What is bad about nuclear fusion?

But fusion reactors have other serious problems that also afflict today's fission reactors, including neutron radiation damage and radioactive waste, potential tritium release, the burden on coolant resources, outsize operating costs, and increased risks of nuclear weapons proliferation. Is Cold Fusion theoretically possible? There is currently no accepted theoretical model that would allow cold fusion to occur. By late 1989, most scientists considered cold fusion claims dead, and cold fusion subsequently gained a reputation as pathological science.

Subsequently, is there waste from nuclear fusion?

A fusion power plant produces radioactive waste because the high-energy neutrons produced by fusion activate the walls of the plasma vessel. The intensity and duration of this activation depend on the material impinged on by the neutrons. Is a pure fusion bomb possible? Despite the many millions of dollars spent by the U.S. between to produce a pure fusion weapon, no measurable success was ever achieved. It has been claimed that it is possible to conceive of a crude, deliverable, pure fusion weapon, using only present-day, unclassified technology.
