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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Cryogenic distillation cascades are proposed to be used today to separate hydrogen isotopes in the fuel cycle of a fusion reactor. It is necessary to design these cascades so that their tritium inventory is minimal. We have thus developed optimization tools in order to simultaneously optimize the structure and the operating parameters of these distillation sequences. This leads to the implementation of a mixed-integer nonlinear programming procedure in a process simulator. The application concerns the International Thermonuclear Experimental Reactor (ITER) isotope separation system. Successive simulation and optimization studies have been carried out which show the accuracy of the simulation and lead to the suggestion of a new arrangement of units for the cascade, with a higher number of columns.
