Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

The extraction of tritium from the liquid alloy 17Li83Pb has been examined taking into consideration the equations related to the design of “droplet spray” and “bubble” extractors in order to verify which are the higher tritium recovery efficiencies which can be realized so as to minimize the permeation of tritium into the water of the cooling system. As far as the droplet spray unit is concerned, the tritium extraction efficiency has been correlated to tritium pressure in the extractor, to the droplet radius and to the residence time of the droplets in the extractor. For the tritium desorption from the alloy, flowing countercurrent to a helium stream in a bubble extractor, the axial dispersion in the liquid and gaseous phases and the effects of gas phase expansion caused by reduced hydrostatic head in the extractor are taken into account. From the results of this study, both the bubble and spray droplet extractors seem to be very appropriate units for tritium recovery from the alloy. Moreover, in order to reach high extraction efficiencies for reducing the tritium permeation to the water cooling system, the spray droplet extractor appears more suitable.
