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.

The possibility of burn control by hydrogen feeding was investigated for tokamak plasma under a self-sustained condition. When fusion power shifts higher than a target value, increases in hydrogen feed rate can lower the power by a reduction in ion temperature due to enhanced hydrogen density. Conversely, when the power shifts lower than the target, stopping hydrogen feeding and exhaust can increase the power through an increase in ion temperature due to reduced hydrogen density. Especially in the latter, in order to enlarge the recoverable magnitude of power shift, it is necessary to select a self-sustained condition having the highest hydrogen density. The results confirmed the possibility of burn control by hydrogen feeding.
