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.

Since all materials of construction are not compatible with spray solutions, an additional problem must be resolved. The corrosion of aluminum and zinc fabricated or coated components in a typical PWR plant when contacted with the sodium hydroxide in the alkaline sodium thiosulfate spray solution is a major contributor to post-accident hydrogen generation. When the hydrogen from metals corrosion is combined with the hydrogen generated from radiolytic decomposition of the coolant and the Zircaloy-water reaction of the overheated fuel cladding, hydrogen can reach a flammable concentration level in the reactor building within 1 to 2 months after a LOCA.
