Web8 nov. 2013 · Here are some facts about polonium. What is polonium? Polonium-210 is one of the world's rarest elements, discovered in 1898 by scientists Marie and Pierre Curie and named in honour of her country of origin, Poland. It occurs naturally in very low concentrations in the Earth's crust and also is produced artificially in nuclear reactors. WebA D-T Fuel powered reactor can achieve injection rates of up to 1000 mb/t, however a very large supply of fuel is needed to sustain the reaction. The injection rate determines how fast fuel is pumped into the reactor, and thus how much energy is produced. The minimum injection rate for most reactors is 2, for water-cooled reactors it is 4.
