U.K.’s NWS gets input from young people on geological disposal
Nuclear Waste Services, the radioactive waste management subsidiary of the United Kingdom’s Nuclear Decommissioning Authority, has reported on its inaugural year of the National Youth Forum on Geological Disposal forum. NWS set up the initiative, in partnership with the environmental consultancy firm ARUP and the not-for-profit organization The Young Foundation, to give young people the chance to share their views on the government’s plans to develop a geological disposal facility (GDF) for the safe, secure, and long-term disposal of radioactive waste.

The methodology necessary to design a solvent extraction plant for isotope separation by chemical exchange is outlined. This process involves the calculation of the number of stages used in banks of mixer settlers used in such a plant. The feed is introduced at both ends of the plant, and the product is withdrawn at one end and the tailings at another. The resulting analysis, illustrated for the case of uranium enrichment, produces a fairly simple algorithm, and then more complicated configurations are examined. The method of design can be used for other systems where the isotope separation factors are more favorable.
