you can't weaponize the waste from them so thats why we stopped using the LFTR

>> No.5870350

Because nothing is as ever as easy to engineer as it is to make a power point of, and people are scared of nuclear power.

LFTR are actually the safest kind of reactor there is. No chance of a hydrogen explosion and the waste isn't able to be weaponized. Thorium is a common as dirt so it would be relatively easy to harvest enough to power multiple cities

the problem is in the wording nuclear and reactor because every one thinks chernobyl and fukushima

>> No.5870475

its an utterly alien technology to the current nuclear fission industry, which is incredibly starved for research funding (there almost isn't any at all). they're also quite paranoid about "new" stuff since they have every reason to fear gremlins in the system.

basically this means LFTR will propagate very slowly into energy policy unless it becomes an issue as big as gay marriage

yes I know, but the LFTR don't use hydrogen so an accident like fukushima can not happen

to be scientifically literate doesn't mean you have to be a scientist as a profession, it just means that when you hear the word nuclear reactor you know what is happening in order to get the energy so you don't automatically think of terrible accidents

fun fact; the potentially biggest problem with a lftr reactor is letting the fluorine gas escape.
the fuel salt will freeze to solid almost instantly if there's a hole in the primary loop, so no escape risks there
but the fluorine is really nasty shit

really, it's more like a chemical plant than a nuclear reactor

alpha particles are very harmful if not contained. They cannot penetrate the skin, sure, but if alpha emitters are allowed to enter the lungs then badness follows.

the reactor is so incredibly neurton heavy that none of the really nasty long term stuff can stick around for very long, it gets kicked further up the periodic table until it gets so unstable it fissions down into the really short half-life waste products.

i believe if you build your reactor right, the longest half-life waste product is like 60 years? so it drops to background after about 300 years. Making a waste storage cask that can be bulletproof for 300 years is shit-easy compared to 10,000

LWRs don't use hydrogen either, buddy...

Either way, like I've said hundreds of times before, there are better intermediate reactor designs. Besides, there's no reason to abandon the Uranium fuel cycle when it can be simplified with U-238 fast reactors (one of the intermediaries, which btw, has much of the same advantages of LFTRs). Not to mention that the biggest barriers to LFTRs are materials problem and only ONE of those (temperature tolerances) exist for something like U-238 HTGRs.

The only people looking into LFTRs in the US are pop-sci morons with no scientific or engineering background.

>LWRs don't use hydrogen either
Not that guy, but there's the water, which in bad situations dissociates into oxygen and hydrogen.

While the reactors at Fukushima weren't the LWR type, they also used water. Hence the hydrogen explosions.

>> No.5870993

>>5870965
I'm aware of this. Technically, it was the high temperature reaction between water and the zircalloy fuel cladding which produces Zirconium Oxide and hydrogen gas.

Also, ALL the reactors at Fukushima are LWRs.

>> No.5871129

more like BOREium power.
more like that.

>> No.5871215

>>5870965
the hydrogen explosions weren't really that important in the whole series of events at fukushima, and they probably had to let that happen anyway.

the explosions didn't cause any damage to the important parts of the reactor, it just blew the rather fragile roof off, which is what it's supposed to do

but LWRs are still kinda iffy in scenarios like that.
