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.

Two three-dimensional neutron streaming problems are analyzed by using the Monte Carlo coupling technique. One is streaming through a two-legged cylindrical-annular duct and the other is streaming through a slit. The main advantage of breaking the problem into two Monte Carlo calculations is that it is then not necessary to repeat the calculation of neutron transport from the reactor to the pseudo-detector when the duct or the slit configuration is changed. The coupling technique provides a remarkable improvement in both the calculated results and the fractional standard deviations as compared with usual Monte Carlo calculations. The agreement between the measured reaction rates and the calculated values is quite satisfactory. The calculated values using the coupling technique agree with the measured values within a factor of 2 for In(n,n′) and Ni(n,p) threshold detectors in the two-legged cylindrical-annular-duct problem, and agree within a factor of 3 with results from cadmium-covered gold activation detectors and from In(n,n′), Ni(n,p), and S(n,p) threshold detectors in the slit problem. However, there is a relatively large discrepancy between the calculated and the measured values from the cadmium-covered gold activation detector in the cylindrical-annular-duct problem.
