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.

An analysis (in terms of different figures of merit) of the performances of several recently proposed tokamaks (IGNITOR, Compact Ignition Tokamak, IGNITEX, JIT, Enhanced Tokamak, Next European Torus, Candor) has been performed. The analysis was carried out according to different scaling laws and in various operating scenarios (temperature and density profile control, low and high energy confinement modes). In the plasma model, profile consistency between current density and temperature was assumed, taking into account neoclassical conductivity and the related physical constraints. The profiles obtained simulate the experimental data fairly well for both lower and higher collisional plasmas. A code was developed for this purpose that produces the stationary state contours for a given tokamak at different additional power levels once the scaling law is fixed. For a given machine, automatic analyses of these diagrams can be carried out for different confinement scaling laws and operating conditions. For a given scaling law and operating scenario, the code scans the configuration space looking for the “machines” capable of reaching ignition according to some simple technological constraints. The results for the most conservative situation are also shown.
