lol...Then you should be glad it's built in France, correct? Anyway, ITER started as a french project, then a EU project, and now I don't even know...
The reactor is a working prototype of a fusion power plant. It is a step up in size over existing plasma chambers, of which there are a few. Its purpose is to learn more about fusion, AND to iron out problems in future fusion power plants (making sure they won't go bang). And, overall, we don't know shit about fusion. We're not talking about fusion bombs here, at least hopefully...
