How much more uranium and/or thorium does that make available? For instance for Thorium, the Atomic Energy Commission has studied the available resources in 1969 (section 4.2, table 4.2). Of this thorium, we've hardly used anything since those days. The report raises the question how much thorium is recoverable at a price of 500$/kg in …

• Thorium is 3 to 4 times more abundant than uranium, widely distributed in nature as an easily exploitable resource in many countries and has not been exploited commercially so far. Thorium fuels, therefore, complement uranium fuels and ensure long term sustainability of nuclear power.

Thorium and uranium reactors use different fission reactions, which means the reactions have different products and properties. Uranium reactors use uranium-235 as their fissile fuel, as well as the plutonium-239 that is produced from the uranium-238 that is also present in the fuel, and this reaction produces enough neutrons to perpetuate the ...

The benefit of a thorium reactor is that just one ton of this element can produce as much energy as an estimated 200 tons of uranium. Yet, when thorium is compared to coal-fired power plants, the difference is much greater. One ton of thorium can create the same amount of energy as 3.5 million tons of coal.
