Bear in mind that Helion's magnets will not be superconductors. Last I saw, they were looking at an aluminum alloy. Exposure to D-D neutrons isn't likely to be a structural problem at least, since you don't get the helium buildup in materials that you get with D-T.
The presentation says they think they can get a 5X gain with D-3He, and they think that's sufficient given the efficiencies of their heating and extraction.
- _0w8t 4y agoThe new video by the same guy https://youtube.com/live/wK5v1Nw98xs https://youtube.com/live/wK5v1Nw98xs from 32 min describes how Helion will get a lot of D+T neutrons from the secondary reactions despite all their efforts. Even without that the neutron flux from D+D reaction by Helion own admission will be enough to do a lot of damage within days of operation based on experience with slower fission neutrons.
