Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

A new procedure has been developed to decontaminate carbonate wash streams relevant to the Purex process from alpha-emitting actinides (238U, 237Np, 240Pu) and the fission products (95Zr, 144Ce, 106Ru). The actinides, forming with Na2CO3 carbonato complexes, for example, [UO2(CO3)3]4-, [NpO2(CO3)3]4-, and unstable Pu(IV) complexes, are retained on the weakly basic anion exchanger resin Bio Rex 5. Plutonium(IV) forms complexes or precipitates nearly completely, when standing for some time or heating up to 70°C. The precipitate can be separated from the carbonate solution by a 2-µm filter mounted in front of the column. Neptunium and the fission products coprecipitate partially at the same time and therefore are also retained. Uranium and the species (neptunium and fission products) remaining in the filtrate are also removed by the Bio Rex 5 column, whereby the effluent of the column is decontaminated to >99%. The recovery of the actinides and fission products from the resin and the filter is performed with three column volumes of 4MHNO3 >99%.
