>Whats wrong with Liquid fluoride thorium reactors
it makes sadfrog happy which is contradiction in sadfrog

Super heated flouride salts.

explain.

mostly political

There are still a dozen engineering challenges to prove out, and it will take millions to work through them all. This in a very anti-nuke atmosphere thanks to Fukushima. Also fierce competition with other Gen III and Gen IV designs wanting to be built to replace our current decaying nuclear infrastructure.

China has the best hope of developing LFTR at the moment. After making a splash last year, none of the other thorium groups (FliBe, Weinberg foundation) have made any progress.

At ambient pressure.

I don't think you know how superheating works.

so what?
overpopulation and religions will still kill mankind and out planet over the next century

>2012
>Using nuclear power

I seriously hope your governments don't do this

because coal is so much better.

>overpopulation
Human population will eventually stabilise, and then drop dramatically. This is because as people's lives becomes easier, comfortable and education levels grow, the population becomes less likely to have more children. You can see this in developed countries today, like japan, Northern europe etc etc. Lot of them have demographic problems.

>religions
This is only a problem in USA, middle east, Africa and other shitholes. Civilised countries don't have an overwhelming majority of retarded biblethumpers trying to establish a theocracy. And even in some countries religiosity is dropping rapidly.

It is in fact really that good. There are some design challenges, but no showstoppers and nothing unsolvable.

LFTR is what fusion wanted to be.

At least coal power doesn't threaten to wipe out all life of earth.

>he thinks overpopulation is a problem facing mankind
>he doesn't know that underpopulation is the real spectre on the horizon

In a few short decades human society is going to inundated with geriatrics, and lacking in young people actually capable of productive work.

is china the only leader in this field atm? how about eu? is it looking into it as well?

>>4707528
>EU
>leader in anything

>>4707489

>he believes the "demographic crisis" propaganda

Number of old people will drop equally sharply a few decades from now as it increased in the baby boom (mortality follows natality with 70 year delay), and suddenly we wont know what to do with all the pension money.

Besides, technological automation is making more and more human work obsolete. We need far lower fraction of populace working to support us all, and this trend will only continue in the future, with technological advance.

>technological automation is making more and more human work obsolete

And how! Look at those youth employment statistics in Europe and the USA. Apparently you think having more people on benefits is a good state of affairs.

how about the airbus and soon Galileo bro?

just dont start another youropoo murrricca shit

I was just interested that is all :(

>This technology was first investigated at the Oak Ridge National Laboratory Molten-Salt Reactor Experiment in the 1960s. It has recently been the subject of a renewed interest worldwide.[2] Japan, China, the UK, as well as private US, Czech and Australian companies have expressed intent to develop and commercialize the technology. Flibe Energy aims to develop a small modular reactor version using liquid FLiBe salt.

Nope automation will greatly reduce the need for able bodied workers.

It happened in agriculture.
It happened in fabrication and its only gonna increase with better AI, cheaper better robots and 3d printing.
Its happening in the service industry. (Think about that the next time you go to an ATM, buy something online or use the self check out at a store)

Reason was, no weapon material, reason is: lobbists.

Hold the fuck up everyone...I'm here.

Ya, the problems in the salts. Despite what has been said, superheated salts pose a huge corrosion problem. There are very few metals resistant to it, but they do exist. Unfortunately, they don't exist in quantities that would make them cheap to build large reactors with (by large, I mean 3000+MWth). Additionally, you have to deal with the fact that half the fission products within the salts are water soluble. This, combined with corrosion is potentially a larger issue than they would be in traditional light water reactors. Additionally, throium is not fissile, but instead fissionable and would operate on the fast neutron spectrum. This technique hasn't been used in large power producing plants and would require that a generation of nuclear technicians relearn neutronics as it applies to these systems. Don't even get me started on liquid metals.

On the other hand, there seems to be greater potential in modular LWRs, advanced full-size LWRs, or high temperature gas reactors. In the case of the latter, the engineering barriers to market are much the same as thorium (fast spectrum neutrons, heat-induced corrosion) but there are fewer of them, and the fuel remains encased (disallowing migration of fission products).

Anything else?

its okay everyone I have the infographic
