The newest era of workforce development at ANS
As most attendees of this year’s ANS Annual Conference left breakfast in the Grand Ballroom of the Chicago Downtown Marriott to sit in on presentations covering everything from career pathways in fusion to recently digitized archival nuclear films, 40 of them made their way to the hotel’s fifth floor to take part in the second offering of Nuclear 101, a newly designed certification course that seeks to give professionals who are in or adjacent to the industry an in-depth understanding of the essentials of nuclear energy and engineering from some of the field’s leading experts.

Activation calculations were performed f or 27 elements in the STARFIRE, Mirror Advanced Reactor Study (MARS), and GA Technologies, Inc. (GA) conceptual reactor first-wall neutron spectra. In all the spectra, seven of the elements (nitrogen, aluminum, nickel, molybdenum, copper, niobium, and lead) required restrictions on their concentration in a material in order to meet current regulations for near-surface radioactive waste disposal. For nickel, molybdenum, and niobium in the spectra of MARS and GA, however, the activation levels are two to five times lower than in STARFIRE. Multistep reactions were found to have only a small effect on the limits for these seven elements.
