Slow, expensive, riddeled with corruption, long ago surpassed by renewables. Why should we use it?

[–] mEEGal@lemmy.world 50 points 15 hours ago (27 children)

only antimatter could provide more energy density, it's insanely powerful.

produces amounts of waste orders of magnitude lower than any other means of energy production

reliable when done well

it shouldn't be replaced with renewables, but work with them

[–] Hugohase@startrek.website 11 points 15 hours ago (11 children)

Yes, but energy density doesn't matter for most applications and the waste it produces is highly problematic.

85% of used fuel rods can be recycled to new fuel rods. And there's military uses for depleted uranium too. So, essentially every bit of the waste can be recycled. Can't say the same for fossil fuels.

"85% of used fuel rods can be recycled" is like "We can totally capture nearly all the carbon from burning fossil fuels and then remove the rest from the atmosphere by other means".

In theory it's correct. In reality it's bullshit that will never happen because it's completely uneconomical and it's just used as an excuse to not use the affordable technology we already have available and keep burning fossil fuels.

Capturing all the extra carbon from the atmosphere is not as expensive as it sounds like. It can easily be done by a few rich countries in very few decades once we stop adding more there every day.

Recycling nuclear waste is one of those problems that should be easy but nobody knows what the easy way looks like. It's impossible to tell if some breakthrough will make it viable tomorrow or if people will have to work for 200 years to get to it. But yeah, currently it's best described as "impossible".

What?

For starters, carbon capture takes an insane amount of power. And to follow up: we couldn't even build the facilities is "a few decades" even if we free power and infinite money.

[–] marcos@lemmy.world 2 points 5 hours ago

Yep, "insane amounts" of power like you what you get by investing something like 1% of a few countries' GDP in PV panels.

[–] StrongHorseWeakNeigh@lemmy.world 4 points 14 hours ago (1 children)

Yeah, you're not making any sense. How is the recyclability of nuclear fuel rods an excuse to keep burning fossil fuels? That's a massive leap in logic that demands an explanation.

[–] Gullible@sh.itjust.works 10 points 13 hours ago (1 children)

They’re saying that plausible uses don’t necessarily translate to real world use, in practice. I have no stake in this, just translating

[–] GiveMemes@jlai.lu 3 points 13 hours ago

While I understand where they're coming from, it should be noted that they're likely basing their experience with recyclability on plastic recycling which is totally a shit show. The big difference comes in when you realize that plastic is cheap as shit whereas uranium fuel rods are not.
