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.

Gamma-ray heating rates from 60Co and 137Cs are measured independently in a stainless steel sphere using thermoluminescent dosimeters (TLDs) with different sensitivities and atomic numbers, a useful check on dosimetric measurements. Gamma-ray dose-weighting f factors, based on the general cavity ionization theory, are applied to convert the net TLD dose rates into gamma-ray heating rates in stainless steel. Gamma-ray spectra are calculated using the ANISN computer code together with the DLC-41/VITAMINC cross-section library. The experimental and the calculated gamma-ray heating rates are compared. The calculation-to-experiment (C/E) ratios of the heating rates are close to unity at experimental positions near the gamma-ray source and show drop-off at far positions. This C/E discrepancy comes primarily from the calculations; however, there is a minor contribution to the C/E discrepancy from the TLD overresponse at low gamma energies.
