While fusion is a nuclear process, the products of the fusion reaction (helium and a neutron) are not radioactive, and with proper design a fusion power plant would be passively safe, and would produce no long-lived radioactive waste.
In the United States and formerly Canada a ton is defined to be 2,000 pounds (907 kg). Where confusion is possible, the 2240 lb ton is called  long ton  and the 2000 lb ton  short ton ; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.here confusion is possible, the 2240 lb ton is called  long ton  and the 2000 lb ton  short ton ; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.
I've read a statement in an educational lecture that there is 2000 pounds in 1 ton. Is that true? If there is 1000 kg in 1 ton and there is 2.2pounds to 1 kg then how can 1 ton be 2000 pounds? It should be 2200 pounds, right? What is the story here?
