We have disposal technology, it just isn't economical or politically supported: the material can be reprocessed, splitting it into the transuranic elements. The uranium and plutonium can be reused as fuel, americium and other elements with industrial use directed as such. The waste left that has no use can then be stored in a smaller footprint... And as a bonus to reprocessing, would only be hazardously radioactive for 150 years rather than thousands.

Just post something π
All that shit costs money. Just toss the waste wherever and wait for public funds to appear, amiright?
This post is incorrect, and harmful. Casks do not only last for up to 100 years. They are given a 20 year certificate, and a renewable 40 year certificate inperpetuity pending safety inspection of the casket.
That's similar to what's done with a lot of mine wastes, which are just as harmful, if not more.
Millions of tonnes of metal-rich tailings are held back at a given mine by their engineered dams. The only thing stopping a 'tee hee whoops' is routine inspection and maintenance, even in post-closure
It is not at all similar. Those mines were just sealed off from the outside world with the dangerous materials therein left to polluted surrounding ground waters. These are stand alone and separated containers meant to hold these wastes indefinitely, until such time as their half lives render them no longer a threat.
You're thinking abandoned mines. Closed mines are different, and the difference is big. With closed mines the objective is to return the land to its preexisting land use or one that supports something else equally as valuable.
To do that, wastes are managed in a variety of ways. Usually the biggest issues are related to water quality and preventing contamination. Landscapes are re-established and reclaimed. It's not just dust your hands and walk away like it used to be.
Edit: sorry, I thought you were arguing they dontast that long. My brain skipped the "only" at the beginning.
The image you linked literally says they last 100+ years. Sure, they need to be checked on to make sure nothing is going wrong, but when is that not the case with hazardous material storage?
Wow. Thatβs excellent perspective on how little waste nuclear plants create!
It's even more efficient these days. French reactors produce miniscule amounts of waste
Doesnβt seem like much, tbh
It really isn't burning coal etc. Will kill way more people and do way more damage than just having this sit around chilling
there's an awful lot of people here that don't understand volume over output. this is a small amount for 24 years when compared to the volume of toxic waste that fossil fuel plants put out.
Even the amount of radiation is lower, as coal power plants output quite a bit of radioactive material
This makes it a robust interim solution until permanent deep geological repositories are available.
Molten Salt Reactors can mostly eat these; until the newer ones come out that can eat these more easily.
Technology will find a way, with proper resourcing.
"The casks are expected to last 50β100 years...". Let's see 2025-1972=53 years. Sounds like it is nearing time to start replacing these or to figure out a better solution to reuse the high level waste.
I'm pro-nuclear power. don't get me wrong. but....spent nuclear fuel does not account for all the radioactive waste produced in fission power production. even the majority of it by mass or volume. low and intermediate radioactive waste represents a MUCH larger footprint
Very much so. Anything that gets too hot has to be interred.
Nuclear energy is downright silly. "These rocks get really hot when we put them close to each other, let's boil water with it to turn turbines" lmao like something outta the scp foundation
Computers run on magic runes written in gold.
on top of that, the information represented within them modifies itself, like characters dancing around and shaping new patterns, hence the nickname of "dancing spirits"
Even weirder when you think about cpus. "Here's a rock we filled with lightning and tricked into thinking."
It would be nice to see a comparison with the waste generated by other sources, over the same period and the same amount of energy generated
I don't trust modern US corporations to manage anything.
How long until people can live near Chernobyl?
People could live near Chernobyl on day one.
until permanent deep geological repositories are available
I have been growing up with the outlook that one day we might find these yet somehow this promise/hope still sounds exactly the same many many years later
I too have played satisfactory. Next step, more containers on top of these.
What ever happened to Yucca Mountain? I thought that was supposed to solve America's nuclear waste problem for good.
They've been talking about that since I was in primary school in the 1980s.
The problem is the weak railroad and interstate infrastructure. There are too many derailments and crumbling bridges to transport such 'hot' materials safely. There's also the danger of hijacking and making of dirty bombs.
Who certified the casks? If it was a private corporation, forget about the 50 to 100 years.
The casks are expected to last 50β100 years, though the fuel inside remains radioactive for thousands.
In other words, kicking the can down the road. "I hope they find a solution, but I don't care. I'll be dead by then."
The casks are continuously recertified for as long as the material needs to be held. Radioactive material decays into non radioactive elements over the course of its half life. This is not kicking the can down the road.
The nuclear energy industry is the safest industry anyone has ever worked in, and it is intentionally so. Please go watch any number of resources on this fact.
Welcome to the world of mining. Metal leaching/acid rock drainage (ML/ARD) is a big issue associated with waste rock, and the solution is often an engineered cover that limits oxygen and water ingress (as these react with sulphur, lowering pH and releasing bound metals in the form of leachate). These covers often use geomembranes that have lifespans of 25 years... Yet you have 300 million tons of ML/ARD waste rock entombed by them.
Look up the Giant Mine - that one will make your head spin.
