Comment on China has world’s first operational thorium nuclear reactor thanks to ‘strategic stamina’
ameancow@lemmy.world 4 days agoFor the amount of actual nuclear waste, it kind of is. Earth is so huge and the amount of waste so small, that you could bury some under a mountain somewhere and chances are high that it would never see daylight again nor would never be found by anyone in the future.
Even despite this, extraordinary measures are taken to make sure nothing escapes the containment until such time that Earth’s crust has completely rolled down into the mantle or the mountain erodes, which by then it wouldn’t be nuclear waste anymore.

We need to store the waste for thousands of years. This is bad. We are able to recycle the waste for more power but we’re not allowed to because it produces a tiny bit enriched uranium and that’s not allowed by the pact the US and Russia made. But recycling waste is tech from the 70’s and it can reduce the half life of 100.000 years to 100 years.
Thorium however, is a different story. It doesn’t work with gamma radiation but with alpha radiation. Alpha radiation is the most dangerous form of radiation, but it doesn’t go far and doesn’t go through many things. You can contain it with a piece of paper. Gamma radiation is the least harmful form of radiation but the big issue is it goes really far and goes through almost anything.
So waste from a Thorium reactor is much less harmful, easy to contain, also has a very short half life (I don’t know how long but it’s really short, as in several years) so Thorium really is awesome. Thorium is also a waste product of many other mining operations so it’s already a form of recycling. The downside of a Thorium reactor is that it’s far more complex than the reactors we know so it’s very hard and expensive to build, more than a regular reactor. So it will cost a lot, takes a long time, but it’s an extremily safe and wise investment.

I feel like you didn’t read my comment and just wanted to talk about thorium. Which is fine, yes I know it generates less waste and creates its own fuel and all that, I am speaking about nuclear waste as we know it right now, from our hundreds of traditional power plants, the things that MOST people associate with dangers of nuclear waste. Which I explained is not even remotely the problem people think it is, because those thousands of years pass in a blink of an eye deep under earth’s crust.

Yeah but traditional nuclear power can be with much less waste which has a much shorter half life if we recycle the waste, is my point. Less than 100 years instead of thousands. But the recycling process which dates from the 70’s is banned because the process also provides a tiny bit of enriched uranium.
So I’m not against traditional nuclear power, I think we can do much better if we recycle, plus Thorium reactors are a good addition.

so thorium is harmless… unless you eat it.

Don’t eat Thorium kids!

I don’t eat any type of kids.
