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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

The burning temperatures and oxidation rates for uranium and zirconium metals in air were investigated analytically. The calculations were based on the assumption that the metal-oxygen reaction is controlled by atmospheric diffusion. Reaction is assumed to be limited by the rate at which oxygen can diffuse through a nitrogen-rich boundary layer. Expressions for mass transfer were obtained by applying the Lewis relation to accepted heat transfer correlations. Calculations were made for the case of vertical plates (foils), horizontal cylinders (wires), and spheres in both natural and forced convection. Characteristic dimensions ranging from 0.02 to 10 cm and flow velocities up to 3162 cm/sec (70 mph) were considered. Computed burning temperatures were compared with experimental measurements of the maximum temperature reached by burning foils of uranium, zirconium, and a zirconium alloy containing 14.9 wt.% titanium in natural convection. Experimental temperatures with zirconium were higher than calculated values while uranium temperatures were somewhat below theoretical. The calculations, however, correctly described the variation of burning temperature with foil width and appear to be good evidence for the proposed model of burning.
