Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Bolometers are a powerful tool for diagnosing plasma radiation in a reactor-relevant environment. Resistive and imaging bolometers have been applied to the Large Helical Device (LHD) to measure radiative phenomena. Installed on LHD are 56 channels of resistive bolometers at four different ports, providing total radiated power measurements and radial profiles with 5-ms temporal resolution. Calibration coefficients are seen to vary slightly year to year. Imaging bolometer foils are installed at four ports. Infrared cameras have been used at some of these ports to provide an image of the foil temperature, which can be analyzed to give an image of the radiated power absorbed by the foil. Upgrades of existing imaging bolometers using platinum foils and more advanced infrared cameras with frame rates of 345 and 420 frames/s (minimum time resolutions of 3 and 2.5 s, respectively) are introduced. Variations of the thermal parameters on thin platinum (2.5-m) foils are measured in a calibration experiment. The thermal properties of the foil can be quantified experimentally by measuring the responses of the foil temperature in the form of the peak change in temperature and thermal time (average of thermal decay and rise times) to a chopped HeNe laser. These measurements are made in 1-cm increments moving in two dimensions across the foil or at 63 separate locations. The imaging bolometers are intended to give images of complex three-dimensional radiative phenomena and ultimately provide the data for one-, two-, and three-dimensional tomographic inversions.
