Do you even want floating, radioactive tritium plasma that would also destroy the ozone layer, if it leaks out of its electromagnetic containment and melts and penetrates everything on its way up?
The conditions required to start and maintain a fusion reaction make a fission-type accident or nuclear meltdown based on a chain reaction impossible. Nuclear fusion power plants will require out-of-this-world conditions — temperatures exceeding 100 million degrees Celsius to achieve high enough particle density for the reaction to take place. As fusion reactions can only take place under such extreme conditions, a ‘runaway’ chain reaction is impossible
“Fusion is a self-limiting process: if you cannot control the reaction, the machine switches itself off,”
fusion does not produce highly radioactive, long lived nuclear waste.
I didn't say it could cause "a fission-type accident or nuclear meltdown".
It can cause something entirely different: Escaping tritium plasma. For example when the magnetic containment field fails. The plasma will still be hot and radioactive; lighter than air; able to penetrate every component of the reactor.
It can also slowly leak if not perfectly adjusted.
Can you provide a reputable source for these claims? Otherwise I'll delete the OG comment and its replies. There's no point in leaving up misinformation.
