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.

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.

Tritium exists in environmental samples in three forms: (i) Tissue Free Water Tritium (TFWT) and associated with the organic matter (OBT) under two forms; (ii) bound to oxygen and nitrogen atoms into the material (EOBT); (iii) bound to carbon atoms into the material (NEOBT). The developed analytical procedure allows obtaining accurate and reproducible information for the various tritium fraction determinations.Aiming to follow the distribution and the integration of NE-OBT in the vicinity of a nuclear research centre down to environmental level the analytical procedure was optimized to reduce possible contamination during critical stages such as the E-OBT elimination. Therefore, a new process using steam was designed and investigated leading to promising results.A broad study was initiated to study potential impact of tritium on tree leaves sampled in the vicinity of a nuclear research centre within a radius of about 20 km. Moreover both plane tree and oak leaves have been sampled to establish the NE-OBT mapping. Therefore, for several locations they were sampled twofold for comparison. Appropriate statistical tests allow assessing that the type of tree does not influence the NE-OBT integration in our experimental conditions.
