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.

Confinement and engineering issues of a small (average minor radius ā ≃ 1 m) moderate-aspect-ratio torsatron reactor are evaluated. The Advanced Toroidal Facility design is used as a starting point because of its relatively low aspect ratio and high beta capabilities. The major limitation of the compact size is the lack of space under the helical coils for the blanket and shield. Some combination of lower aspect ratio coils, higher coil current density, thinner coils, and more effective shielding material under the coils should be incorporated into future designs to improve the feasibility of small torsatron reactor concepts. Current neoclassical confinement models for helically trapped particles show that a large radial electric field (in terms of the electric potential, eφ/T ≥ 3) is necessary to achieve ignition in a device of this size.
