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.

Flow experiment and analysis were performed to determine flow instability condition in a single thin vertical rectangular flow channel (1.98 mm in channel gap, 50.8mm in width, and 121.92 or 60.96 cm in heated height), which represents one of the Advanced Test Reactor’s inner coolant channels between fuel plates. The maximum surface heat flux and flow rate are 159.8kW/m2 and 462.5 kg/s-m2, respectively, which simulates decay heat removal from the single heated surface of the Advanced Test Reactor. The tests are conducted at atmospheric and subatmospheric pressure, simulating expected conditions during a hypothetical loss-of-coolant accident. The precursor of the flow instability [the point of net void generation and the onset of flow instability (OFI) defined by Saha and Zuber] was compared, and the OFI map (power density versus minimum mass flux at OFI) was developed in this study.
