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.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

A novel concept of thorium once-through fuel cycle for CANDU-type reactors is proposed. The main innovation of the concept is described, including segregation of enriched uranium from thorium to allow separate fuel management routes. Geometry is chosen to enhance leakage of uranium-born neutrons to subcritical thorium parts of the core. Discharged burnup values for thorium and uranium are subjects to optimization regarding uranium savings benefit. Neu-tronic analysis indicated a potential for significant savings in the uranium requirement (∼50%). Fuel cycle cost calculations based on a simple economic model and reasonable set of economic parameters show no economic penalty in realizing fuel utilization improvements.
