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.

Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

The fire time of concern for a component within a used nuclear fuel transport package is the time after fire ignition when that component reaches its temperature of concern. In this work a legal weight truck package that is designed to transport one used pressurized water reactor fuel assembly is assumed to be in proximity to a 12-m-diameter jet propellant fuel pool fire. Container Analysis Fire Environment (CAFE) simulations are used to predict the fire times of concern for the fuel cladding, seal, lead gamma shield, and liquid neutron shield of the package, for different package locations relative to the fire under no-wind conditions. When the package was centered over the pool, the CAFE-predicted time of concern for the cladding to reach its possible burst rupture temperature (nominally 750°C) was between 11.8 and 13.3 h, depending on the modeling parameter values and mesh refinement. As the package was moved away from the pool center, the cladding time of concern increased, and its in-fire steady-state temperature (reached after being exposed to the fire for a long time) decreased. The cladding did not reach its temperature of concern when the package center was 6 m from the pool center (above the pool edge), even in infinitely long-lasting fires. This type of analysis can be used to determine a “safe distance” between the pool and package centers, beyond which certain components important to safety will not reach their temperature of concern, no matter how long a fire lasts. This will help risk analysts determine which accident scenarios can significantly affect public and environmental safety and those that cannot.
