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.

Are Civil Nuclear Credits still relevant? DOE is asking nuclear operators for input
Interest in new reactor deployments and existing reactor life extensions is surging, encouraged by production and investment tax credits from the Inflation Reduction Act and led by electricity demand from tech companies. Last week alone saw Google and Amazon investing in Kairos Power’s fluoride salt–cooled reactor and X-energy’s high-temperature, gas-cooled reactor, respectively. On October 16, the DOE’s Office of Clean Energy Demonstrations issued a solicitation to award $900 million to support the initial domestic deployment of light water–cooled small modular reactor technologies.

The total neutron cross section of Sm152 has been measured in the energy range from 6.84 to 9.18 ev with the BNL crystal spectrometer using the Be (1231) crystal planes as a monochromator. The resonance at 8.036 ev was fitted to a Breit-Wigner single-level formula by the method of shape analysis. Since the target nucleus is even-even, I = 0, and hence the statistical weight factor g = 1. Consequently all Breit-Wigner parameters can be determined from the total cross section measurements alone. The resonance parameters obtained from the analysis are: E0 = 8.036 ± 0.010 ev, σ0 = 210,000 ± 2000 barns, Γ = 0.201 ± 0.008 ev, Γγ = 0.071 ± 0.010 ev, and Γn = 0.130 ± 0.005 ev.
