THIS is the compelling argument to cease using nuclear energy to power our lives. . . . . . .There must be uninhabited islands off shore where they can dig depositories large enough for these damned fuel rods !! Why use an area that offers agricultural benefits

What is the oldest man made thing on the planet? The pyramids? About 4000 years, right? What's the first thing we did when we discovered them? Right. Here we're talking a 100,000 years. Who the hell will know what is buried there, in even 1000 years? And in JAPAN? Where the earth's crust, well, you know, moves, how can such toxic materials be stored where it could come into contact with water supplies? Where the containers can be crushed, corroded, broken... This is one of the major, amongst many, issues the IAEA brushes over with a near psychopathic dismissal. Stop the madness.

Ticked by whom? The people who are throwing care to the wind and supporting nuclear power? Nuclear waste stays radioactive for thousands of years and they are building a stockpile quicker than they know how to deal with it. There will come a time when they have no where to store it. This will become a death sentence for future generations. I remember reading an article that proposed loading it all onto rockets and firing it at the sun. That would make more economic sense to me. It has to be better than stockpiling it for the future people to deal with.

Even the Finnish have admitted that with a 100,000 year time span, nothing in human terms can be suitable to secure the toxic waste. No metal. No casing, no material is yet up to the specs of withstanding that time span while holding nuclear waste out of the surrounding environment. It's madness.

How can you finance 100,000 years depository? Assuming one person, working 40 hours a week to monitor the site. This means 4 full time employees for 100,000 years. Take a minimal wage of USD 10.-/hours. You end up to about 9 billion USD at today value being ultra conservative just for that. So far there is no money planned for that in any countries using nuke power. I am fine with nuke power as long as safe enough and true costs are covered…. Sorry, no, I am not fine anymore…

They can reprocess and make plutonium to be used in nuclear plants. 17000 tons seems to be enough to explode half of the moon!

Nuclear waste should simply be stored at the sites of its origin (power station), first in water and then in dry caskets. The volume is small, and the sites are well protected anyway. What is the point of shuttling this stuff here and there.
Disillusioned
Fascism!
Then what?
Still no idea!
China syndrome anyone?
I cannot believe anybody would support the use of nuclear energy. Yeah, fossil fuel produces CO2, but do you want to live next to (or above) a nuclear waste dump?
fds
if the government wants to do that they should just buy all the land at whatever the price the land owner asks. they are spending a #$% load of money on it already. what's another couple billion.

Talking about nuclear waste. Back in the 80's the US were dumping nuclear waste in the deep ocean. The containers will last 250 years (they hope), after that the waste will be exposed and releasing large amounts of radiation into the deep ocean. Putting if underground in one of the world's most volcanically active countries just seems like madness.
And for Mike O'Brien, coal ash can be treated and buried. It is much less dangerous than radiation.

Here is your non explosion. Pu-240 makes the bomb very unsafe and relatively inefficient. The explosion is dirty, but I don't thing mad scientists-warn-of-tourism-threat-to-antarctica would care.

So if someone would want to make "Fat man" clone from commercial reactor spent fuel, it would be very unstable and the power of explosion would change by luck, but it would be more than 1kt. (Fat man was 21kt.)
The bomb can't be stored and it would emit so much heat that it would be unbearable for human beings. If someone would manage to transfer it to the detonation point, he doesn't have to bother escaping, because he would die from radiation sickness anyway.

If the alternative to storing the waste in blue plastic bags is to bury it underground in a vast rocky space then I am for that.

No because it won't explode. If you were building a bomb I think you would care if it wouldn't explode.

In Onkalo there are warning text carved in stone every language of the world and drawings of dying men after they study nuclear waste.

Because it explodes too easily. If you would be mad scientist, would you care?
I don't write any more, because my Samsung's automatic text correction has decided that I am writing about wildlife in Antarctica.
Mike O'Brien
No. The physics of nuclear criticality and the design of fuel rods make spent fuel rods no more likely to have a chain reaction than the risk of a granite countertop having a chain reaction. Especially with the simple measure of not storing them within about 6 inches of each other.
No you don't. Plutonium from spent fuel processing is not usable in construction of a nuclear weapon, it is contaminated with isotopes that preclude its use in such a weapon. This is like claiming that spent kitty litter is a security concern because the urea in it can be used to make gunpowder.
Well as the waste isn't explosive, it isn't enough to explode anything.
But the stockpiling of ash from coal plants, which will remain toxic forever (which happens to be a bit longer than 100,000 years) is OK.
Mike O'Brien
Sorry the Totem tests did not use reprocessed commercial fuel. The Pu-240 percentage was much lower than plutonium recovered from a commercial reactor would have in it. The two Totem tests were less than 13% Pu-240 while commercial spent fuel is around 25%.

He's either deluded, or a comedian. Most rural Japanese towns and villages are spiraling down.
disillusioned
I wouldn't mind, as long as all the scientific and technical boxes had been ticked.
Mike O'Brien
And for disillusioned, coal ash is radioactive and even treated it will be toxic FOREVER. Radioactive waste can also be treated and buried and it is and will be less dangerous than coal ash.
