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.

Defueling operations at Three Mile Island Unit 2 involve underwater plasma arc cutting of reactor vessel stainless steel components. Sampling and analysis of released off-gases and aerosols during steady-state plasma arc cutting tests established a conversion fraction of nitrogen-to-nitrogen oxides, off-gas composition, and aerosol concentrations for engineering evaluations of potential health and safety and corrosion issues. The sample results indicate that (a) <1 vol% of nitrogen is converted to nitrogen oxides, (b) the airborne particulate concentrations for the major steel components (chromium, iron, nickel, etc.) could exceed the threshold limit values without off-gas capability, (c) the volume percent hydrogen could exceed its lower flammability limit without off-gas capability, and (d) there is low corrosion potential for off-gas system components for the given torch operations.
