Comment on China’s ‘artificial sun’ breaks nuclear fusion limit thought to be impossible

This is true, the waste issue is different with these two technologies, but I don’t think it’s all that significant in either case.

Fission produces some awful waste, but what I like to point out is just how little it produces. My favorite example is nuclear submarines. Nuke subs have to come to port every so often for food, equipment, supplies, etc, but not because they’re low on fuel. They don’t carry a lot, about 500kg (half ton) and that lasts them a very long time. So how often do they need to be refueled? Once, most subs are refueled just once in their ~30 year lifetime. Some subs will be decommissioned before ever refuelling, using just one set of uranium fuel rods for their whole life.

Given the tiny volume of waste produced over such a long time… We can figure out the storage. Even if the solution is costly, there’s really not much to store, this is very manageable.
