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.

Energy-dependent diffusion theory with a modified one-term degenerate kernel is employed to derive an expression for the detector response in neutron-wave experiments performed in a slab and a cylinder of crystalline moderator. The Watson transform and the Laplace transform modified to finite systems are used and different mathematical representations of the detector output are discussed. From the derived expressions, various decaying modes, including the continuum mode, are calculated for a 100-cm graphite slab. The condition for the existence of the discrete mode is studied, and the maximum frequencies obtained are 7440 cps for graphite and 9300 cps for beryllium. The experiment reported by Utsuro et al. is interpreted and the observed interference pattern is reproduced analytically with a slight discrepancy in the resonance frequency. The potential of this experiment for measuring moderator properties is also discussed.
