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.

Hanford teams prepare for first tank waste transfer
The Department of Energy’s Office of Environmental Management said that crews at its Hanford Site in Washington state are preparing for the site’s first-ever transfer of radioactive waste from one of its large underground tanks, Tank AP-106, to the Waste Treatment and Immobilization Plant (WTP).

The tritium burnup fraction fburnup can strongly affect the design of a fusion reactor since it influences the size of the tritium reprocessing plant, the on-site tritium inventory, and hence, the licensing requirements and cost of the entire plant. In this paper a simple analytic expression for fburnup is derived and then applied to typical parameters proposed for three possible fusion devices: ARIES-AT, FDF, and ITER. We find that for these parameters the burnup fraction is most strongly affected by the global recycling coefficient (through the global replacement time) and the fueling efficiency. The latter term may be the most easily influenced by plant design, such as by high-field-side pellet injection, for example. Because of the hotter edge plasmas in these devices compared to present-day tokamaks, the recycling coefficient will be lower, reducing the tritium burnup fraction. While this may not adversely affect ITER, which is limited to 400-s pulses for the inductive scenario, the tritium reprocessing for nearly continuous operation of devices such as ARIES-AT must be carefully considered in the overall plant design.
