ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Measurements made during cycle 1 operation of Commonwealth Edison Company’s Zion Unit 2 pressurized water reactor core were used to validate the Electric Power Research Institute Advanced Recycle Methodology Program. In addition to the usual reaction rate and axial trace measurements for determining power distributions, gamma scan measurements were available to provide additional data to validate the calculated power shapes. The parallel occurrence of gamma scan measurements and standard nuclear instrumentation measurements provided a unique opportunity to intercompare the results of these measurement methods. The calculated X-Y gamma scan behavior supported the behavior of the calculated X-Y reaction rates. The measured X-Y gamma scans were found to be more accurate than the measured X- Y reaction rates, with the latter showing significant differences among some symmetrically located assemblies. For both types of measurement, however, the modeling of the asymmetrically loaded assembly located furthest in the core periphery produced the poorest results. The axial gamma scan calculation proved very accurate except at the inlet and outlet regions.
