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.

Primary containment computer codes, REXCOHEP (Lagrangian), ICECO (Eulerian), ALICE (ALE), and REXALE (ALE), developed in the Engineering Mechanics Program of Argonne National Laboratory, were validated by performing comparison with the analytical solution and experimental data. Three problems were used. The first problem deals with the propagation of shock wave in a rigid tube for which analytical solution exists. The second problem concerns the response of a simple flexible vessel to a hypothetical core disruptive accident (HCDA)-in-duced pressure loading for which experimental data exist. The experiment was performed with a well-defined and calibrated energy source. It provided reliable test data for code validation. The third problem concerns the propagation of shock wave in a three-dimensional space for which the experimental data exist. Results of the comparisons show that the Lagrangian, Eulerian, and ALE codes can all give acceptable solutions to the shock wave propagations and on the response of containment vessel to HCDA-induced pressure loading.
