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.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

A previously developed formalism is applied to calculate the sensitivity of cobalt prompt response self-powered neutron detectors. Differential and average sensitivities in thermal and epithermal energy regions are calculated, and their dependence on the geometrical factors is studied. A simple analytical expression is proposed for the first-collision absorption probability, which is a good approximation to the exact function. This expression is used to obtain the epithermal selfshielding factor as a function of the radius of the emitter and the parameters of the interaction. The thermal sensitivity, as the main contributor to the current, is studied as a function of the emitter radius. Finally, a criterion to evaluate the accuracy of the parameters of the model is established in the form of some interval rule. This interval rule should encourage the performance of better measurements and calculations.
