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 release of fission products from the Three Mile Island Unit 2 plant during and following the accident was low and consisted almost entirely of noble gases and an estimated 15 Ci of 131 I. Such a small iodine release is surprising considering that 52% of the core inventory of radiocesium and 40% of the radioiodine were released from the reactor core. Significant releases of fission products to the plant systems commenced at 138 min following failure of the fuel rods. The primary pathway to the environment was through the letdown/makeup purification system to the auxiliary building plant stack. The large releases (40 to 50%) of noble gases, cesium, and iodine to the reactor building were contained within the building for 1 yr until the noble gases were released under controlled conditions.
