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.

A simplified computational scheme that can be efficiently applied to predict fully developed axial flow in rod bundle subchannels is presented and compared with experimental results for different flow conditions. Galerkin's finite element method and the physical model of turbulence proposed by Roco and Zarea (1978) are used in this approach.The flow in the corner, wall, and central subchannels for both triangular and square rod bundles is investigated. Different values of the subchannel pitch-to-diameter ratio and various Reynolds numbers are considered. In all these cases, the present computational scheme gives the correct qualitative trends for the distributions of the axial velocity and wall shear stress. The comparison performed with current measurements in the subchannels of a 3×6 rectangular rod bundle and with other available experimental and analytical results taken from the literature shows good agreement.
