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.
As such, since 1 kg is equal to 2.204 pounds, a ton falls short of 1 Tonne by a few kilograms. 1 Ton= 1000 X2.204= 2204 pounds. Ton is mostly used in the US where it contains 2000 pounds. If one tries to calculate its value in kilograms, it comes to around 910 kg.In the old British system of weights, 14 pounds make up one stone, 8 stones make up 1 hundredweight, and twenty hundredweight make up one ton.f you ask someone the difference between a ton and a tonne, it is likely that you may draw a blank as most people think that they are one and the same.
