Another interesting thing I picked up from Pandora's Promise. A while back I was talking with an acquaintance who said he had purchased stocks in a company that specializes in mining for uranium and other such metals but the stock wasn't doing all that well. In Pandora's Promise towards the end a comment was made that US nuclear power plants are frequently fueled on defunct nuclear warheads from the Russian nuclear arsenal. In other words, we are running our nuclear power plants using their refined uranium. It occurs to me that the stocks in the company aren't doing all that well because the nuclear industry doesn't need a supply of uranium if they are using defunct nuclear warheads from the Russian arsenal. I told him to watch the movie. He didn't believe me. It does sound outlandish, I have to admit.
Yes, it is a cycle alright.Gots to be cheaper to "recycle" than to mine new.
What a great closed circle...
Hillary sells our raw uranium to Russians.
They turn it into weapons pointed at us.
We buy the uranium back on its expiration date.
What about fusion energy?
You are thinking short game, brother.
I'm thinking long game. I won't be around to see it, but ... I'm very confident solar and wind is the future.
But, hey, whatever.

It isn't.
WT1 said:Yeah, it's a bomb and the other a power source, but US nuclear power plants use defunct Russian weapons for their source. Same thing really.
No, reactor fuel and weapons-grade uranium aren't the "same thing really".
Megatons for Megawatts ran for twenty years through 2013 and took highly enriched U235 removed from Russian warheads that were already deactivated by treaty and converted it to much much lesser enriched U235 for nuclear reactor fuel.
About 45% of American reactor fuel has recently come from former Russian weapons. Hell, the US even converted some of our weapons-grade uranium from deactivated warheads into reactor fuel, that makes up about 5% of reactor fuel.
All of these former nuclear weapons account for about 10% of power generation in the entire USA...so who gives a shit where reactor fuel was sourced from? It was already made and wasn't used as a weapon as designed, which sounds a lot like a win/win for the world.
You're entitled to your opinionHad a chance to watch the second disk. Nuclear power is not a solution for a safe planet. If it isn't a design flaw, it will be an act of god, damage incurred during a war, operator error, faulty part, ignorance of the technology that is still not completely understood, penny pinching management, you name it. The risk is too high.
I think it is an efficient use of former nuclear weapons. But before it is converted it is still a bomb in a sense, so same thing. Nothing wrong with that, just it is isn't a pile until it is converted as you said. I get it.No, reactor fuel and weapons-grade uranium aren't the "same thing really".

Now Hiroshima and Nagasaki are inhabited. But the stats from several different web sites suggest high rates of cancer such as leukemia: https://k1project.columbia.edu/news/hiroshima-and-nagasaki

There is an excellent book, BTW. Midnight at Chernobyl.

There are some Generation IV reactors that are molten metal cooled. The Terrapower traveling wave reactor is one of them. They killed part of the project in 2019 Gates stated it was all Trumps fault. ( I am not buying that) There are a couple others that are out there. INL's sodium reactor was shut down maybe 10 years ago. I did hear some rumors of them firing it back up. One of the largest challenges is that you have to move heat from the reactor to the secondary and make steam. Biggest challenge with any of the molten metal/salts is them and water mixing is a major problem. Biggest advantage of the primary side being molten metal/salts is the greatly reduced pressures of the primary side. Instead of having 2500psi primary system, some can operate at nearly atmospheric pressures. The Nuscale SMR is one of my favorite designs that is moving forward. We need new reactors and new designs and needed them 10 years ago. The old PWR's especially the Westinghouse designed reactors are still chugging away great. The huge amount of safety related systems and parts obsolescence is putting a hurt on them. These new reactor designs are inherently safer and simpler. Less safety related systems (huuuge costs) passive and inherent shutdown systems make a large difference in the approach to operate and maintain the plant.@DocRDS are you in the theoretical side or the practical application side? I'm curious if the use of liquid metal cooling is/has gained any additional traction in lieu of water cooled reactors.

I was on the experimental side, but the industry moves SLOOOOOOOOOOOW. As I understand it, Liquid metal is the way of the future, but how soon that arrives is anyone's guess. Nukes do have a lot of headwind between environmental activists, govt regulation (aka fees and oversight) and of course replacing established technology like oil/gas. Much of the safety hysteria is overblown (The series shows how you get a disaster of such proportions, which does not exist outside of the former soviet system)--we've had a nuke navy for well on 50+ years not to mention 70+ years with only 2 accidents, one of them severely overblown (3MI) and one of them God reminding us we are not in control (Fukishima).
The hysteria around nuclear technology is so bad, we wouldn't tell people we had plutonium in the building as a radiation source. Nothing weapons grade, but you mention the word Plutonium and SHTF fast.
The Movie Command and Control about the Damascus Titan incident is phenomenal. Until that film came out, I didn’t even know about Damascus.The 1980 damascus titan missile incident could have been really bad too.
Nobody really talks about the environmental impact of sellafield either.
In the early 90’s a hurricane hit south florida, there is a nuclear energy site in biscayne natl park that was supposed to be shut down prior to the storm making landfall in the event of a power failure and backup generators were unable to come online in time to keep the water flow to regulate the reactors, think it came down to about 6 hours time to stop the reaction before the storm hit. Meltdown during a hurricane would have been bad news too.
I think there is a sub at the bottom of the atlantic, maybe the Thresher, that had a bunch of nukes on it...don’t know if it was ever recovered or not.
