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.

A continuous duty cryopump system has been designed and developed that comprises a self-contained cryopump for installation into a vacuum chamber, and a microprocessor controller for automatic operation. This deuterium pump has two units in a single housing, arranged so that one is pumping while the other is regenerating. Liquid helium-cooled and finned sections in each unit pump deuterium by condensation, and an integral collector pump captures the regenerated gas. A microprocessor unit controls distribution of liquid and gaseous helium for conditioning the pumping units and operation of remote actuators for regeneration. Software provides fully automatic, timed sequencing of the repetitive cryopump events, which can be reprogrammed through a keyboard. An override allows manual operation, and interlocks prevent cryogen lockup. The pump is being prepared for testing this Spring.
