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.

The maximum conversion ratio is relative to the highest degree of undermoderation, which is fixed by the necessities of heat removal. But before this utmost limit is reached, other conditions lowering the conversion become effective. Besides safety-relevant coefficients of reactivity and high fissile inventories, there are other symptoms of a potential economic disequilibrium, which can be visualized by examining the whole domain between the highest possible undermoderation and that of today. The physics underlying the changes in fuel recovery have been investigated by studying the neutron balances and the results have been summarized.
