Katy Huff reflects on her time in the Office of Nuclear Energy
After three years in the Department of Energy, including two as assistant secretary of the Office of Nuclear Energy, Katy Huff stepped down in May to return to the world of academia as a professor at the University of Illinois–Urbana-Champaign.
Among her many accomplishments while serving as NE-1, Huff pushed for energy security—both at home and abroad, in places like war-torn Ukraine—and for the development of additional advanced and traditional nuclear plants, the potential restart of shuttered nuclear facilities, and a better funding stream for college nuclear programs.

This paper addresses radiological issues that are unique for accelerator-driven neutron generation with much attention given to the limited area in a spallation target that encloses the propagation of high-energy cascade reactions. At certain beam options, a cascade of neutron-producing processes leaves the alpha-emitting spallation products belonging to the class of rare earths, like 62146Sm, 64148Gd, 64150Gd, and 66154Dy, whose overall toxicity in a lead target might overrun the alpha-emitting activation product 84210Po. To suppress their accumulation, the concept of a heterogeneous liquid-metal spallation module is proposed. This concept envisages the separation of a spallation target into two zones with specifically designated roles of neutron production and neutron multiplication. The main idea is to localize the proton-induced neutron production in a material with Z number <60 so as to exclude accumulation of problematic rare earths. Radioactive 50126Sn from fission products is considered as a material for this zone. Such a configuration not only lifts the great deal of spallation product burden from the lead target but also helps in eliminating the most troublesome long-lived fission ash, and what is important is that, compared to the bulk lead target, there is no appreciable detrimental effect on the overall neutron production.
