Thea Energy releases preconceptual plans for Helios fusion power plant
Fusion technology company Thea Energy announced this week that it has completed the preconceptual design of its fusion power plant, called Helios. According to the company, Helios is “the first stellarator fusion power plant architecture that is realistic to build and operate with hardware that is available today, and that is tolerant to the rigors of manufacturing, construction, long-term operation, and maintenance of a commercial device.”

Summary Paragraph: UNF-ST&DARDS is being developed to provide the ability to perform automated analysis of spent fuel storage and transportation systems. One of the key capabilities of UNF-ST&DARDS is to perform criticality analysis of dry casks. UNF-ST&DARDS allows for modelling the variation of cask payload burnup enrichments and cooling times through a flexible GUI. Users can also modify, neutron absorber loadings, water soluble boron concentrations, and fuel and canister dimensions for fresh and spent fuel. This demonstration will show users how to perform criticality analysis for casks using templates and graphical user interface. Attendees have no requirements to watch the demonstrate, however, an RSICC license for UNF-ST&DARDS and SCALE is necessary if they would like to follow along.
