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.

2024: The Year in Nuclear—July through September
Another calendar year has passed. Before heading too far into 2025, let’s look back at what happened in 2024 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from July through September 2024.
Stay tuned for the top stories from the rest of the past year.

The two power peaks during the Chernobyl accident were analyzed using the system thermal-hydraulic code RETRAN-02. The time and magnitude of the first power peak predicted by the RETRAN model compared well with the data presented by the Soviets. The analysis also revealed that one of the contributing factors to the second power peak was the depressurization of the system. Depressurization occurred upon rupture of the pressure boundary, which was caused by the first power peak. The depressurization of the system generated more voids, resulting in additional reactivity insertion, which produced a second peak. A parametric study showed that the positive reactivity introduced by the scram rods and the reactivity caused by the positive void coefficient were both important in contributing to the accident.
