Climate Change

nuclear power isn't hard tho

Found a pretty cool chart showing radioactive decay surrounding the plant in the 5 years since the Fukushima meltdown.



You need about 100 msv/year to begin to show a statistically significant increase in cancer risk, so anything outside the red/orange is safe. The amount the red has decreased in 5 years is pretty amazing.

The Japanese did not fuck around with the cleanup.

Pretty sure that most of this effect is simply radioactive Cesium-134 decaying into a stable state and no longer releasing radiation. Its half-life is only 2.06 years, so you'd expect less than 1/8th of the original material to be present by now.

I prefer "60 years of Godzilla movies motivated them" as an explanation. It amuses me more than your boring, fact based reality Archi.

Or they clearly developed the Japanese Miracle ahead of schedule.

Well, they've got experience.

If you want a good primer on how daunting (to put it very very mildly) the task ahead is if we have any chance of avoiding more than 2 degrees celsius of warming, here:

Are y'all ready for zero net greenhouse gas emissions worldwide by the time you're contemplating retirement? Because that's what it's going to take.

Besides the biggest problem being people ignoring or not believing scientists or saying for every scientist that says there's global warming there's one that isn't, I feel a huge issue with pushing for climate change actually being scary is the 2 degree Celsius number.

People don't understand or realize how fucking bad 2 degrees is. Firstly, they think it means Fahrenheit and that we're still going to have snow in the winter and heat in the summer. Secondly they don't realize that the barrier island they keep building houses on here will be underwater and the bay will become the ocean and my property value (and taxes) are going to go way up.

Dunno if anyone else saw this dumbass segment on Last Week Tonight



The biggest problem is that he's conflating real problems with shitty 1940's/1950's waste disposal from nuclear weapons with waste disposal from nuclear power, as if every storage site is a Hanford site, as opposed to emitting no detectable radiation whatsoever.

But getting to his point that "we CANT just leave nuclear waste in dry cask storage where it is!!!!"

These dry casks that store the spent fuel rods after they have cooled sufficiently in the spent fuel pools, even those built before I was born, are essentially indestructible. If something occurred like an asteroid strike that was able to actually compromise the casks, that would be the least of our concerns.

I think the more interesting thing about that video is how horrifically deadly crashes were in 1970s vehicles. Even at 60mph the cabin of that truck crumpled like a cardboard box.

I only know how shit is run on the US Military side of things. Rods from a decommissioned ship are transported in a container on a train to a site where they're placed in a pool, eventually cut up, placed in that dry cask (Which is safe enough to go up and touch. They're pretty warm).

The big take away I got from Last Week Tonight was the complaint being not about the method of storage, but the where and the fact that we don't have a permanent deposit site because turns out no one important wants nuclear waste buried in their state.

I see nothing wrong with continued dumping in the Jersey Shore.

Which is silly because MOST states have nuclear waste sites. While the politics surrounding Yucca Mountain have been stupid for decades, the idea that a centralized permanent deposit is even necessary is honestly not true at all. France gets over 80% of their electricity from nuclear power (4 times what the US does) and where do they store their waste? On site at each plant in dry cask storage, just like we do.

If this wasn't framed like "nuclear power waste is super dangerous anywhere it exists because nuclear weapons waste at Hanford was horribly managed" then we'd be able to see this more clearly.

But clearly that wasn't the point of the segment. It's more fun to rant about "radioactive alligators" or whatever.

What about radioactive wolves?

[archibaldcrane]

"Scary mutations" lol.

[Fiye]

btw those casks you featured in your video aren't the final resting place for said spend fuels. Those are the shipping containers to transport them to said pools so they can be further cooled down and cut apart to be placed in cement storage.

I should spend some time finding references for this shit. The training we got on the enterprise about defueling/deactivation was legit cool.

[archibaldcrane]

Yeah, they end up looking like this:

(Which is safe enough to go up and touch. They're pretty warm).

But is it safer then teabagging reactor vessels while shutdown?

As far as "waste" goes from what I've read mines themselves have always been a bigger problem. Particularly to the Navajo

Dunno my studies show you're likely to get cancer but my sample size is real small.
