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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Several types of adsorbers have been studied as they are considered for the first stage of water detritiation systems processing more than 100kg/h of high-level tritiated water generated in a future fusion plant. Zeolite is a suitable adsorbent since it is an inorganic material having a large water capacity. Rapid dehydration characteristics as well as a large HTO/H2O separation factor is necessary for the adsorber to minimize its size. Present experiments were focused on the effect of cations on HTO / H2O separation and dehydration characteristics of Y-type zeolites. The selected cations are Na, K and Ca. The flamework SiO2/Al2O3 ratio of the zeolites is fixed to 5.0 in the present experiments. It was found that the isotope separation factors are around 1.1-1.2 under static conditions. As for dehydration, operating temperature fixes the capacity of movable water from the zeolites. The capacity at room temperature is NaY > CaY > KY. HTO dehydration characteristics depend on the accumulated purge gas amount, while the purge gas rate is less influential. Effect of temperature on HTO dehydration is also less influential especially in the early stage of dehydration. Pressure swing is an effective method for HTO dehydration.
