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.

Transport calculations have been performed using the one-dimensional gamma-ray transport code ASFIT for materials of high atomic number (Z), such as tin, tungsten, lead, and uranium, for incident energies in the range of 0.030 to 0.5 MeV, where the fluorescent X rays are important. The relative impact of different components of K X rays on the spectra and buildup factors at various depths in the medium has been assessed for a typical case. Approximate analytic results are derived and compared with the computed X-ray contributions. Point isotropic air and medium response buildup factors computed for these materials have been given, filling the gap in the existing standard tables. Since the buildup factors are not amenable for conventional interpolation in this region, the values are given at close intervals of incident photon energy.
