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.

WHAM: Realta gets first plasma with 17 Tesla magnets in mirror fusion test
The magnetic mirror fusion concept dates to the early 1950s, but decades ago it was sidelined by technical difficulties and researchers turned to tokamak fusion in their quest for confinement. Now it’s getting another look—with significantly more powerful technology—through WHAM, the Wisconsin HTS Axisymmetric Mirror, an experiment in partnership between startup Realta Fusion and the University of Wisconsin–Madison.

No-public evacuation is an expectation for fusion power plants (FPPs) from the public and governments. In this technical note, a preliminary consequence assessment of an ITER wet bypass–like accident (the accident with the most severe consequence in ITER) of a helium-cooled deuterium-tritium tokamak FPP is performed and compared with that of ITER. Ideal gas–based methodology is proposed to evaluate the released materials in accidents, which is verified by typical accident cases in FPPs. The verification indicates that, compared with the best estimated codes, the proposed method is much simpler and easier with effectiveness. The accident assessment shows that this helium-cooled FPP design may still need public evacuation if the accident happens, which demonstrates the requirement of further investigations for FPP accidents. Some suggestions are proposed to improve the safety of FPPs based on the assessment.
