Depleted Uranium

6-1-2019Uranium (chemical symbol U) is a naturally occurring radioactive element. In its pure form it is a silver-coloured heavy metal, similar to lead, cadmium and tungsten. Like tungsten it is very dense, about 19 grams per cubic centimetre, 70% more dense than lead. It is so dense a small 10-centimetre cube would weigh 20 kilograms. The

Thorium Myth vs Facts – AIM Truth Bits

The effective use of thorium as a nuclear fuel, by definition, implies a system that employs chemical processing to separate uranium from thorium, and fuel from fission products. Chemical processing of any type is very difficult with solid nuclear fuels, like uranium dioxide fuel or thorium dioxide fuel.

Thorium may also be concentrated from monazite sands by caustic digestion at 150 C and 40–50% NaOH for several hours to form a hydrous metal oxide solution. This solution is crystallized, dried, and dissolved in HCl from which it is precipitated at pH 5.8 by NaOH addition to produce a uranium and thorium bearing cake.

Thorium and Uranium Mining in Haiti?

Whatever grade of uranium-thorium is in Haiti, especially on the Majescor-SOMINE property, would seem to be low grade, making it more of a liability to talk about than to ignore, (lest they be required to take additional precautions).

Uranium-232 has a half-life of 68.9 years and is a side product in the thorium cycle. It has been cited as an obstacle to nuclear proliferation using 233 U as the fissile material, because the intense gamma radiation emitted by 208 Tl (a daughter of 232 U, produced relatively quickly) makes the 233 U contaminated with it more difficult to handle.
