T his chapter outlines the basic steps involved in mining processing and reclamation that might be suitable for uranium ore deposits in the Commonwealth of ia For uranium ore deposits the choice of mining methods and processing options is very deposit-specific and dependent on many variables such as the quality and quantity of the ore the shape and depth of the ore greater abundance of thorium than uranium confers no advantage other than a very marginal advantage in energy security to those countries in which it is abundant 3 2 Relative utility of thorium and uranium as fuel Claim: of the thorium is usable as fuel in contrast to the low (~0 7%) proportion of fissile 235U in natural uranium

Now that you have your raw material you need to process it in a Centrifuge to get Uranium-235 and Uranium-238 Both of these types of uranium are needed in nuclear power generation The recipe for a Centrifuge is: Although mining is the best way to obtain uranium it can also be obtained by as process called Nuclear fuel repossessing This

Thorium is a gray heavy metal often mined with rare earth metals It was also used mig welding rods and Coleman lamp mantels Today thorium is no longer used in most applications and has little commercial use It can be converted to nuclear fuel in an atomic reactor and its waste products are not as problematic as uranium fission products

Transport d'uranium Le cycle de l'uranium ncessite de nombreux transports comme celui par le rail de ce conteneur contenant du nitrate d'uranyle L'uranium tant peu radioactif les prcautions prendre tiennent surtout aux proprits chimiques des produits transporter

Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90 Thorium is silvery and tarnishes black when it is exposed to air forming thorium dioxide it is moderately hard malleable and has a high melting point Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state it is quite

Plutonium as an Energy Source

These surpluses have re-ignited the debates around the world about the use of plutonium as an energy source and provided new arguments for continued assistance to on-going plutonium projects This article reviews the basic facts regarding plutonium use and provides some cost and technical analysis of the issue

Les avantages des racteurs au thorium sont trs nombreux : le Thorium 232 est plus abondant que l'uranium on peut l'utiliser contre quelques pourcents pour l'uranium et il n'y a pas besoin de l'enrichir le 232Th tant fertile et non fissile il

Aluminium with a purety exceeding 99 998 % produced by electrolytic refining such as obtained at the outlet of the refining tank without subsequent processing its rare earth content being less than 100 ppb and its total uranium and thorium content being less than 20 ppb The invention also concerns a cost-reducing method for the manufacture of said aluminium
