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.

Laboratory examination of debris recovered from the upper tubesheet of the Three Mile Island Unit 2 Bloop steam generator was performed as part of a series of technical evaluations of postaccident core damage. The analysis of a sample of loose, gravel-like debris is of special interest since it is believed to have been transported from the core region during the core damage sequence between 174 and 192 min to the upper tubesheet when reactor coolant pump B was restarted. The characterization of five size fractions and ten of the largest particles was accomplished by destructive (chemical, radiochemical, metallography, and scanning electron microscopy/energy dispersive spectrometry) and nondestructive (photographic examination and density) methods of analysis. The results of this examination provided direct information on the extent of core damage when restart occurred.
