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.

Melt refining as a means of uranium decontamination of metallic wastes was examined. Samples of mild steel, contaminated with uranium, were melted by adding SiO2-CaO-Al2O3 ternary system fluxes. Various melting temperatures and times were used, and the uranium concentrations in the resulting ingots were determined. Flux, and hence slag, composition was found to influence the level of decontamination, but melting temperature and time had little effect. Using the most effective flux composition (10 SiO2-50 CaO-40 Al2O3), uranium concentration was lowered from a contamination level of 500 to 0.027 ppm, a value nearly that of the initial steel before contamination. When the ionic character of slag was defined using basicity [the mole ratio of basic oxide (CaO) to acidic oxide (SiO2 + Al2O3)], the optimum decontamination value was found near a basicity of 1.6. The slag anions of silicate or aluminate seemed to affect the uranium decontamination.
