    What is Uranium? How Does it Work - World Nuclear Association

    Uranium is a heavy metal which has been used as an abundant source of concentrated energy for over 60 years. Uranium occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the Earth's crust as tin, tungsten and molybdenum. Uranium occurs in seawater, and can be recovered from the oceans.

    Thorium vs. Uranium Fuels | Thorium Power Canada Inc.

    Naturally occurring thorium has one isotope- thorium-232. In the DBI reactor, the initial start up fuel mix is a combination of thorium and uranium-235. The uranium acts as the "seed" source of neutrons needed to achieve criticality for the first reactor.

    Uranium - krivarochem

    The enrichment plant concentrates the useful U-235, leaving about 85% of the uranium by separating gaseous uranium hexafluoride into two streams: One stream is enriched to the required level of U-235 and then passes to the next stage of the fuel cycle. The other stream is depleted in U-235 and is called 'tails' or depleted uranium.

And here is one place the thorium-uranium fuel cycle differs from the uranium-plutonium fuel cycle. Most thorium-fueled designs are breeder reactors, meaning they produce more fissile material than they consume.
