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.

Siting of Canadian repository gets support of tribal nation
Canada’s Nuclear Waste Management Organization (NWMO) announced that Wabigoon Lake Ojibway Nation has indicated its willingness to support moving forward to the next phase of the site selection process to host a deep geological repository for Canada’s spent nuclear fuel.

We use molecular dynamics simulations to study the irradiation-induced point-defect clustering kinetics in CeO2 as a surrogate for UO2, the most widely used nuclear fuel. Remarkably, the cluster-formation mechanism involves a partial self-healing response of the perfect crystal to the radiation-induced defects, by spontaneous creation of new point defects with negative formation energy. These "structural" defects neutralize the cluster by screening its long-range Coulomb potential, thereby localizing the damage. The observation of a similar lattice response in MgO and UO2, in spite of very different types of clusters involved, suggests that this partial self-healing screening behavior may be intrinsic to all ionic crystals.
