uranium thorium coal

power plants (such as coal). In light of pushes for more clean energy, this investigation analyzes the current state of the U.S.'s nuclear system and suggests an alternative to the uranium paradigm – thorium. Thorium is an element that is more than 3 times more abundant worldwide and is an alternate source of nuclear power.

Reactors that use thorium are operating on what's called the Thorium-Uranium (Th-U) fuel cycle. The vast majority of existing or proposed nuclear reactors, however, use enriched uranium (U-235) or reprocessed plutonium (Pu-239) as fuel (in the Uranium-Plutonium cycle), and only a handful have used thorium.

In contrast, uranium is found in both the mineral and organic fractions of coal. Some uranium may be added slowly over geologic time because organic matter can extract dissolved uranium from ground water. In fly ash, the uranium is more concentrated in the finer sized particles.

The reason uranium won out over thorium at the dawn of the Atomic Age was its ability to undergo fission and provide material for atomic weapons. Thorium was safer, cleaner and more abundant than uranium, but because nuclear weapons could not be built from it, it was relegated to a footnote in atomic energy journals for the past half century.

More Fuel efficient. Thorium provides a much more fuel efficient process than uranium, coal, oil, natural gas, and any renewable source. If thorium reactors provided all the needed electricity for the US, we would only need 5,000 tons of thorium per year as opposed to 35,000 tons of uranium per year, or 3.5 million tons of coal per year.

There is a vast difference between the use of thorium in conventional technology and its use in Thorium Power Canada technology.. One of the key ways Thorium Power Canada's technology differs is that the Thorium Reactors are designed to breed artificial uranium-233 from thorium, burn most of that fuel as soon as it is bred, and store the minor amount of unburned fuel.

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.
