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.

Senate committee hears from energy secretary nominee Chris Wright
Wright
Chris Wright, president-elect Trump’s pick to lead the U.S. Department of Energy, spent hours today fielding questions from members of the U.S. Senate’s committee on Energy and Natural Resources.
During the hearing, Wright—who’s spent most of his career in fossil fuels—made comments in support of nuclear energy and efforts to expand domestic generation in the near future. Asked what actions he would take as energy secretary to improve the development and deployment of SMRs, Wright said: “It’s a big challenge, and I’m new to government, so I can’t list off the five levers I can pull. But (I’ve been in discussions) about how to make it easier to research, to invest, to build things. The DOE has land at some of its facilities that can be helpful in this regard.”

The neutron spectra in a concrete assembly bombarded by 14-MeV neutrons are measured by a miniature NE-213 spectrometer and the multifoil activation method. The results obtained are within experimental error. The measured spectra are compared with calculated results obtained using the two-dimensional DOT3.5 transport code with 125-group structure cross-section libraries based on ENDF/B—IV, JENDL-2, and JENDL-3T (the test version of JENDL-3). In the deuterium-tritium neutron peak region, the measured and calculated neutron spectra are in agreement. However, all the calculations overestimate the measurements by 10 to 50% in the mega-electron-volt region. In a still lower neutron energy range, where the 197Au(n,γ)198Au reaction is dominant, discrepancies from −30 to +40% are observed. Possible reasons are considered, but none explain the discrepancies. Further investigation of the secondary neutrons in the mega-electron-volt region emitted by elastic and inelastic scattering from the main components of concrete, such as oxygen, silicon, and calcium, is necessary to improve the agreement between experimental and calculated results.
