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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

ANS announces 2025 Presidential Citations
One of the privileges of being president of the American Nuclear Society is awarding Presidential Citations to individuals who have demonstrated outstanding effort in some manner for the benefit of ANS or the nuclear community at large. Citations are conferred twice each year, at the Annual and Winter Meetings.
ANS President Lisa Marshall has named this season’s recipients, who will receive recognition at the upcoming Annual Conference in Chicago during the Special Session on Tuesday, June 17.

A MOOSE (Multiphysics Object-Oriented Simulation Environment) based application, TREX, has been developed for modeling and simulation of advanced ceramic waste forms at multiple length scales. A method was developed for incorporating microstructural details at the mesoscale and computing effective material properties that can then be applied at the engineering scale capable of modeling the entire waste form. The work described includes the creation of Kernel, Material, and Postprocessor objects necessary to model the advanced ceramic waste form. Using these developed tools, the diffusion of cesium was modeled in a hollandite waste form. Experimental data and first principle calculations taken from the literature were used to inform models of the hollandite material properties.
