09/01/2007 · Uranium vs. Thorium: Mining, Processing, Waste Generation January 9, 2007 December 5, 2012 Kirk Sorensen blog, Unegorized I've taken a little time to do another comparison slide between the waste generated in a typical lightwater reactor compared to a liquidfluoride thorium reactor.
28/09/2016 · The idea is to remove plutonium, which is chemically distinct from uranium, and let it fission in proximity to thorium. Then the neutrons it emits while fissioning are captured in thorium to ...
• Natural zircon contains uranium and thorium in varying quantities and from an environmental aspect this is problematic • The industry accepted standard is U+Th <500 ppm • High brightness is a marketing advantage • Removal of uranium and thorium achieves the production of a premium product • Sell a zircon sand to the ceramic market
The sorption of uranium and thorium from their aqueous solutions by using 8hydroxyquinoline modified Nabentonite (HQbentonite) was investigated by the batch technique. Nabentonite and HQbentonite were characterized by Xray fluorescence (XRF), Xray diffraction (XRD), scanning electron microscopy (SEM), and Fourier Transform Infrared (FTIR) spectroscopy.
When including uranium extracted from the oceans it becomes an inexhaustible source of energy. But in a molten salt reactor one can also use thorium as a fuel and it is estimated that there is a factor 3 more thorium on earth that uranium. Thorium is easily accessible and at this moment is mostly a byproduct of rareearth mining.
nuclides. This paper reviews the technologies used for separating uranium and thorium from rare earths in rare earth production, particularly in China. Some potentially applicable methods, such as precipitation and solvent extraction for the separation of uranium and thorium from rare earths in different media were also reviewed. 2015 Elsevier Ltd.
removal of uranium, thorium, radium and possibly all alpha emitting actinides. The established process was able to generate decontaminated effluent up to 1 ppm of uranium, less than 1 ppm of thorium and 35 Bq/L radium which corresponds to Bq/g of solid for alpha and Bq/g of solid for beta activity. ...
Removal of uranium and thorium from aqueous solution by ultrafiltration (UF) and PAMAM dendrimer assisted ultrafiltration (DAUF). Journal of Radioanalytical and Nuclear Chemistry 2015, 303 (1), 441450.
21/07/2021 · SINAP has two streams of TMSR development – solid fuel (TRISO in pebbles or prisms/blocks) with oncethrough fuel cycle, and liquid fuel (dissolved in fluoride coolant) with reprocessing and recycle. A third stream of fast reactors to consume actinides from LWRs is planned. The aim is to develop both the thorium fuel cycle and nonelectrical appliions in a 2030 year .

Apart from the portion of the uranium removed, the sludge contains all the constituents of the ore. As long lived decay products such as thorium230 and radium226 are not removed, the sludge contains 85% of the initial radioactivity of the ore. Due to technical limitations, all of the uranium present in the ore can not be extracted.
26/01/2007 · Extraction chromatography with commercially available UTEVA resin (for uranium and tetravalent actinide) was applied for the separation of Th and U from control solutions prepared from a multielement control solution and from sample solutions of solidified simulated waste. Thorium and U in control solutions with 15mol/dm(3) HNO(3) were ...

Author information: (1)The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Study of the Earth's Interior, Okayama University at Misasa, Tottoriken ...
To optimize the separation of uranium and thorium from the Yen Phu xenotime leachate, countercurrent simulations of extraction, scrubbing and stripping were done in a series of mixersettler units.
