Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

In the solvent extraction processes for reprocessing spent nuclear fuel, operational flow problems may be caused by the formation of stable emulsions, commonly called “crud.” Our experiments have demonstrated that crud is generated by finely dispersed solids. Such fines can be produced by precipitation of zirconium with degradation products of tributyl phosphate. Experiments show that crud can also be produced by other solids, however, viz., finely divided silica and bentonite. Therefore, fines present in the aqueous feed solution might also produce crud. A special problem arises in the reextraction step in the Thorex process, where a precipitate of thorium dibutyl phosphate causes crud formation.
