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.

The application of nuclear heat in chemical processes involves a novel safety problem caused by contamination of the product gas with tritium. For a 3000-MW(thermal) nuclear process heat installation, a study was made on tritium distribution. Based on conservative assumptions and a calculation model for source/sink balances, an upper limit for the tritium concentration in the product gas of ∼5900 Bq/m3 (STP) was derived. The critical pathway in the application of the product gas then leads to a radiation exposure being far below the German 0.3 mGy ( 30 mrem) annual whole-body dose concept. Improvements in the calculation model and additional data for modified design features may further reduce the tritium contamination.
