Comment on China’s ‘artificial sun’ breaks nuclear fusion limit thought to be impossible
Cocodapuf@lemmy.world 8 hours agoThis 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.

My problem is that waste being unborn next generation’s problem. Who are we to demand them to keep guarding our shit? With fusion, the waste is the alive-generation’s problem.

You could say that of any infrastructure. Bridges are expenses, ongoing maintenance for them is a burden our children will have to bear. But I expect they’ll be willing to do it.
The fact is, most of what we do affects the next generation, we just don’t think about it, or can’t quantify it. The only difference with nuclear is that we can quantify it.
