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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

NEA panel on AI hosted at World Governments Summit
A panel on the potential of artificial intelligence to accelerate small modular reactors was held at the World Governments Summit (WGS) in February in Dubai, United Arab Emirates. The OECD Nuclear Energy Agency cohosted the event, which attracted leaders from developers, IT companies, regulators, and other experts.

High-resolution and high-accuracy total cross sections of 9Be, 10,11B, and 12,13C have been measured from 1.0 to 14 MeV. The Los Alamos Scientific Laboratory Tandem Accelerator was used to produce a “white” source of neutrons by stopping a pulsed beam of 15-MeV deuterons in a thick beryllium target. The neutron energy resolution (full-width at half-maximum) achieved in kiloelectron volts is given by 1.4E(MeV)3/2, and the accuracy of the neutron energy scale in kiloelectron volts is given by ±E(MeV) [0.00744E(MeV) + 0.01592]1/2. The statistical uncertainties in the transmission vary from 0.5 to 2%, and the systematic error in the transmission is estimated to ±1.7%. The cross sections are compared with those in the ENDF/BIV library where appropriate. The high statistical accuracy of the 11B data, for example, has revealed fine structure at high excitation energy (around 9 MeV), which correlates with the structure observed in charged particle measurements on the same compound nucleus. There are also indications of additional structures that have not been seen previously in the 12B compound nucleus at this excitation energy.
