uranium thorium Solutions Just Right For You

Thorium is a dark grey radioactive metal of which the principal source is the ore monazite a complex phosphate of thorium uranium cerium and lanthanides The metal is soft and ductile and is extracted by precipitation as the hydroxide along with cerium and uranium separation is achieved by further extraction with tributyl phosphate from an acid solution Thorium dioxide (ThO 2) also called thorium(IV) oxide is a crystalline solid often white or yellow in color Also known as thoria it is produced mainly as a by-product of lanthanide and uranium production Thorianite is the name of the mineralogical form of thorium dioxide It is moderately rare and crystallizes in an isometric system The melting point of thorium oxide is 3300 C – the

A brief summary of recent British work on the powder metallurgy of uranium and thorium is presented Uranium powder is produced directly from urania following production of a stable homogeneous oxide attained by decomposing ammonium diuranate The urania thus produced is reduced with calcium or magnesium followed by compacting and sintering

Thorium occurs in several minerals the most common being the rare earth-thorium-phosphate mineral monazite which contains up to about 12% thorium oxide but on average 6-7% Thorium-232 decays very slowly (its half-life is about three times the age of the earth) but other thorium isotopes occur in its and in uranium's decay chains

Basically this is carried out in a fast or thermal reactor where the thorium-232 is irradiated with uranium 233 and absorbs a neutron converting it to thorium–233U a fertile material which can now be used as a fuel in a thorium nuclear reactor Overview of Reactors Operating on Uranium and Thorium Fuels 1 Uranium Reactors

In contrast with the uranium-plutonium cycle described above thorium reactors are fuelled with non-fissile thorium and a small amount of fissile uranium-235 which starts the fission chain reaction As thorium reactors are breeder reactors once they start running there is no need to add more fissile material as it is generated within the reactor

Thorium fuels can breed fissile uranium-233 This uranium-233 can further be used in various kinds of nuclear reactors Recent indications are that in the near future thorium would emerge as a fission fuel of greater potential than thorium Distribution of Thorium in the world Monazite is the chief source of thorium in the world

General Information About Uranium in Ceramics Paul Frame Oak Ridge Associated Universities General Ordinary ceramics often contain elevated levels of naturally occurring radionuclides e g K-40 and the various members of the uranium and thorium decay series

Thorium oxide is used for high-temperatore laboratory crucibles it is added to glass to create glasses with an high refractive index and low dispersion (lenses for cameras and scientific instruments) Like uranium thorium could be a source if nuclear fuel Thorium can be burnt in a nuclear reactor without generating plutonium

Even more available than uranium in the earth's crust is thorium (roughly three times the abundance) which can be used in conventional reactors to breed uranium fuel (U-233) Once-through thorium fuel cycles in CANDU for example can achieve near-breeder status and almost render uranium availability an irrelevant issue

Why aren't we using thorium in nuclear reactors given the possibility of a meltdown is nearly zero and the waste cannot be used to make bombs? — Dennis Dorando Concord Calif In a word precedent It's certainly possible to base nuclear reactors around thorium as opposed to the most commonly used element uranium

Thorium thinkers please let me clue you in Uranium is not your enemy Thorium does not work as a fuel without substantial quantities of either U-235 or Pu-239 to provide the neutron flux that turns your favorite element into an isotope that will fission to release almost exactly the same amount of heat per unit mass as fissioning either uranium or plutonium
