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 designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

The spatial and temporal evolution of the 3H levels in the water of the River Tagus in its passage through various regions of Spain and Portugal was analysed. Using mathematical time-series techniques, analytical expressions were obtained for the temporal trend and the periodicity present in the data.These expressions were used to determine the transit times between the sampling sites. The results indicated that the mean speed of 3H displacement was 12 km/month. The residence times of tritium in the water were also obtained. They were found to depend on the sampling points, with values ranging between 31 and 77 months. The concentrations of 3H varied cyclically at the six sampling points, with periods of around 24 months upstream of the Almaraz Nuclear Power Plant and about 12 months downstream.
