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 Dynamic behavior of the JT-60 vacuum vessel was examined during its power tests to confirm the validity of the dynamic response analyses of the vacuum vessel. Observed accelerations and displacements showed good linearity with electromagnetic forces and reached maxima of 48 m/s2 in acceleration and 0.46 mm in displacement at full power operation. The observed natural frequency was approximately 50 Hz, showing good agreement with that predicted by the dynamic response analysis. Dynamic response analyses showed that the vibration mode with a natural frequency of 46.3 Hz had a displacement amplitude of around 0.1 mm at the rigid ring under the misfire start-up operation conditions. The difference between the displacement predicted in the dynamic response analyses and that observed at the lateral port could be explained by the lever ratio effect of the lateral port.
