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.

Annual Conference opening plenary: Full speed ahead
The 2024 American Nuclear Society Annual Conference opened with a bang yesterday as 1,200 attendees gathered in Las Vegas to network, collaborate, and socialize. Honors and awards were presented to several recipients, and ANS welcomed twelve new Fellows.
The plenary opened with an address from ANS Executive Director/Chief Executive Officer Craig Piercy that brought this year’s theme to the fore straight away: The time is now to deploy new nuclear projects—and not acting at this moment is simply not an option.

The objective is to develop equilibrium fuel cycle designs for a typical pressurized water reactor (PWR) loaded with homogeneously mixed uranium-thorium dioxide (ThO2-UO2) fuel and compare those designs with more conventional UO2 designs.The fuel cycle analyses indicate that ThO2-UO2 fuel cycles are technically feasible in modern PWRs. Both power peaking and soluble boron concentrations tend to be lower than in conventional UO2 fuel cycles, and the burnable poison requirements are less.However, the additional costs associated with the use of homogeneous ThO2-UO2 fuel in a PWR are significant, and extrapolation of the results gives no indication that further increases in burnup will make thoria-urania fuel economically competitive with the current UO2 fuel used in light water reactors.
