    If anything has been consistent about fusion its always them desperately trying to spin babysteps and monumental leaps forward and trying to make themselves seem super clean and safe especially compared to fission.

      That’s usually the media outlets sensationalising the results to the point where the articles are grossly misleading.

      trying to make themselves seem super clean and safe especially compared to fission.

      That’s just a fact, no need to try. The Fusion process is inherently safe the radioactive byproducts are generally short lived and easier to handle.

        If publications keep misreporting your work, stop talking to them, and see different publications with a stronger commitment to the truth.

        Fusion is not inherently safe. It has significantly higher rate of neutron discharge for the enegy produced which can damage the reactor vessel and potential to cause nonfuel material to become radioactive.

        Ontop of any power disruption of the system has the potential for radioactive plasma to escape with nothing even remotely equivalent of a SCRAM to bring it back under control.

        The only reason fusion appears safe right now is because its all still developmental phase and any issues are being handwaved as prototyping issues and not treated like the actual potential catastrophes they are.

          The total mass of reactants in the fusion chamber is below milligram, some of which is bound in stable isotopes. Even if all of it escaped, it would be far from catastrophic.
          The reaction itself cannot run away on its own because it requires a delicate balance in temperature and density, which will be immediately disturbed if there was a breach in containment.

          The walls will be activated by neutrons, but short of blowing the reactor up, there’s not much chance of materials escaping in a significant amount to pose a danger.

            Just for comparison: The nuclear safety requirements of a fusion reactor are ballpark those of the radiology department in your local hospital: An accident will give you, if you’re unlucky, a dose on the order of a dental x-ray. Decommissioning involves letting it sit there for 100years until it has cooled down to ambient radioactivity levels, if you’re cheeky you could send it to a place where the natural radiation levels are higher and declare it cool much faster.

            Why does noone talk about those ludicrously strong magnet fields and gigantic vacuum vessels? You’re standing right next to a massive volume of practically nothing and are worried that something leaks out?
