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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

The ITER Neutral Beam Test Facility (PRIMA - Padova Research on ITER Megavolt Accelerator) is planned to be built at Consorzio RFX (Padova, Italy). PRIMA includes two experimental devices: a full-size plasma source with low voltage extraction called SPIDER (Source for Production of Ions of Deuterium Extracted from RF plasma) and a full-size neutral beam injector at full beam power called MITICA (Megavolt ITER Injector Concept Advancement).The beam source components are exposed to high and focused heat loads during beam production, and they are actively cooled, being at high voltage, by ultrapure water, which flows through cooling channels machined inside the components. The high power loads, the complexity of the cooling circuits, and their small, rectangular cross sections are design critical issues.The results of the tests carried out on the single cooling channel prototypes (SCPs) for the SPIDER accelerator grids and their performances in terms of pressure drop and heat exchange calculation are presented. The SCPs have been tested in environmental conditions similar to injector ones, i.e., they have been subjected to thermal loads up to the average heat power density of 1 MW/m2 , in a vacuum environment (0.5 Pa). The experimental results have been cross-checked with computational fluid dynamics analyses and analytical models.
