Compound method for the continuous enrichment of nuclear fuels
Creators
Description
A method is suggested to enable fossil fuels (such as coal, asphalts, oils) to be economically favourable processed with about 0.1 kg uranium per ton raw material and thus enrich the nuclear fuels. The compound method designs the production of calcium carbide and utilization of the waste heat, where the nuclear fuels are enriched in lime mud. Multiple recycling and addition of nuclear fuel contained flux materials where necessary (e.g. non-regenerable ion exchange resins) as well as the inclusion of further process steps are to reduce the costs.

Es wird ein Verfahren vorgeschlagen, das es ermoeglichen soll, fossile Brennstoffe (wie Kohle, Asphalte, Oele) mit ca. 0,1 kg Uran pro Tonne Rohmaterial wirtschaftlich guenstig aufzuarbeiten und dabei die Kernbrennstoffe anzureichern. Das Verbundverfahren zieht die Herstellung von Calciumcarbid und Ausnutzung der Abwaerme vor, wobei sich die Kernbrennstoffe im Kalkschlamm anreichern. Mehrmalige Recyclierung und gegebenenfalls Zusatz von kernbrennstoffhaltigen Zuschlagstoffen (z.B. nicht regenerierbare Ionenaustauscherharze) sowie Zuschalten weiterer Verfahrenschritte sollen die Kosten herabsetzen.
