Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Physics calculations have been performed for repeated plutonium recycling in tight pressurized water reactor lattices. These calculations made use of the transport theory code CASMO combined with a 70-group nuclear data library variant that was created recently. The calculational model, which performs well for normal thermal reactors, was tested against measured data for tight lattices from the Swiss reactor PROTEUS. The test results are reasonably good and the model was applied to tight lattice power reactors without any modification. Four reactor systems, three of which contain tight lattices with plutonium recycling, were treated. The fourth one represents recycling in a normal lattice. Calculated results are given for various parameters. Particularly important are the natural uranium savings in the tight lattice systems relative to net consumption in the normal lattice system. The values found are between 10 and 35% for an ∼50-yr operating time for each system. However, in some of the calculations, the void reactivity results are positive. For these cases, there may actually be positive values in reality—especially in the latter part of the time period studied— which would lead to restrictions and somewhat reduced savings.
