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 sensitivity of coupled neutron-photon transport simulations to the underlying nuclear data is studied for oil well logging applications using the Monte Carlo radiation transport code MCNP4C. Results obtained with the JEF-2.2, ENDF/B-VI.5, and JENDL-3.2 data libraries reveal large discrepancies, confirming immediately the importance of well-established nuclear data. In order to refine this conclusion, the impact of several nuclides is determined by varying their neutron and photon total cross sections. As a next step, neutron cross sections and photon production cross sections are modified per reaction channel to identify the most important nuclear reactions playing a role in C/O logging. The influence of neutron and photon angular distributions is studied as well. The outcome of this analysis is a list of nuclear reactions that have a significant impact on borehole logging tool simulations in different environments and, therefore, would deserve much attention in the construction of a new library for oil well logging.
