The chemical symbol for Plutonium is Pu. Plutonium is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when ... WebMay 18, 2024 · It will reduce the world’s stock of plutonium; and because of the higher melting point of thorium-MOX, nuclear reactors will be much safer. As thorium is not itself fissile and cannot be directly usable in a thermal neutron reactor, by absorbing a neutron, it will transmute to uranium-233, which is an excellent fissile fuel.

• Abundance. Thorium is three times as abundant as uranium and nearly as abundant as lead and gallium in the Earth's crust. The Thorium Energy Alliance estimates "there is enough thorium in the United States alone to power the country at its current energy level for over 1,000 years." "America has buried tons as a by-product of rare earth metals mining", notes Evans-Pritchard. Almost all thorium is fertile Th-232, compared to uranium that is composed of 99.3% fertile U-238 and 0.7% … WebA method of chemically separating plutonium from thorium. Plutonium and thorium to be separated are dissolved in an aqueous feed solution, preferably as the nitrate salts. The feed solution is acidified and sodium nitrite is added to the solution to adjust the valence of the plutonium to the +4 state. A chloride salt, preferably sodium chloride ...
