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.

Nu-HOPE (Nuclear-Highly Optimized Prandtl number Experiment facility) is a newly built facility in UNIST to simulate molten salt reactor. Due to the high-temperature corrosion and toxicity issue, the heat transfer phenomena of molten salt are studied under similarity technique with high-Prandtl number simulant fluid. 12-meter-high Nu-HOPE was designed for the study of both natural and forced circulation of high-Prandtl number fluid. Experimental results of natural and forced circulation can give the evaluation of heat transfer characteristics and fluid stability model for the simulant molten salt. In this paper, design of Nu-HOPE based on numerical approach to developing heat transfer model of high-Prandtl number fluid is suggested.
