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.

Pew shows majority support for U.S. nuclear
A number of surveys and polls, such as Bisconti Research and University of Michigan surveys, have found steady or growing support for nuclear energy among Americans during the past several years. The Pew Research Center on Aug. 5 reported its nuclear-related findings from its survey conducted in May with a representative sample of U.S. adults. The results show 56 percent of respondents favor the construction of additional nuclear power plants in the United States.
That level of support is similar to last year’s findings (57 percent support) and is up substantially from the 43 percent, 50 percent, and 54 percent that Pew Research reported in 2020, 2021, and 2022, respectively.

In the ANAIS experiments, water was injected as a jet or a spray at a given temperature and a given flow rate onto a superheated (~1600°C) molten steel layer for an imposed value of the heat rate delivered to the steel layer by induction heating. At the beginning of a test, water was injected during a few seconds with a high flow rate. Thereafter, the flow rate was decreased to evacuate the thermal power under steady-state conditions. The heat generation rate in the metal was maintained during the water injection at ~1 MW/m2, which represents a typical reactor situation. The test results showed that the steel-water heat transfer led to different final situations depending on the injection mode and water velocity. In addition, the water-cooling power was rather high at the very beginning of the transient and comparable to the heat rate delivered to the metal layer in steady-state conditions. Also, it was observed that no steam explosion occurred in any case, and that a solid layer always formed at the steel free-surface.
