They probably didn't use thorium for power stations because it requires entirety of it to be new R&D, which costs at least tens of billions of dollars, if not hundreds. With uranium, the R&D was already done for them because they are piggybacking off of the research done for military weaponry.

'Without exception, [thorium reactors] have never been commercially viable, nor do any of the intended new designs even remotely seem to be viable. Like all nuclear power production they rely on extensive taxpayer subsidies; the only difference is that with thorium and other breeder reactors these are of an order of magnitude greater, which is why no government has ever continued their funding.'

BTW: many beaches in Brazil are composed of monazite sand. A percentage of this sand is composed of thorium oxides. As a result, the beach is quite radioactive. So much so, in fact, that if you take a fun day on the beach, you would reach the yearly ionizing radiation limit set by the EU. And seeing that the half life of thorium is 14 billion years, this radiation isn't going away any time soon. 🙂

Hi hello, I just would like to make a question for better understanding. I see in this video that the reaction is based on destabilization of the physical mass of nucleo and real values are not integer, so radioactivity is still in what remains untill the product find stability right? This means producing a lot of material that is shooting material all around right?

Would you upload a video of how a touchscreen works?

I know nothing about chemistry let alone nuclear matter but man this is some interesting stuff

We can also use Plutonium 239 from U238 by using a Breeder reactors. Pu 239 is quite efficient in nuclear fission.

This my first time known that you don't need isotope to have chain reaction but only with the probability issue, same as the thing that I found the household microwave oven isn't provide the best frequency or wavelength for the water and so on molecules.

Oh,that's actually pretty easy. It's like a syringe.You pull in hydraulic oil with it and once pressed out it goes thru a smaller diameter pipe which by the law of physics has increased pressure. To understand it easier take a sharp needle and blunt needle,if you try to penetrate something ofc you'd be penetrated by the sharp one because it has more pressure focused into a smaller area. That's how they work as well,you take a big metal cylinder that can hold lots of pressure and you add inside a hydraulic oil which is low in viscosity but veeery dense,you pump the bigger cyilinder and it pushes everything into a smaller one out which then you work with(bending or whatever you need a press for) To push the handle which moves the liquid around it's usually made with leverage by the same principle i explained before or an electro motor which pumps it. Hope i got it right,correct me if there's a guy who understands them a lot.

@@farqilion8747 I think you mean it has a low reaction cross-section. Protium has a high affinity for neutrons because it already has an unpaired proton, but the deuterium nucleus is already balanced. So fast neutrons from the reactions collide but do not get absorbed easily and instead transfer energy to the deuterium as heat, and the neutrons themselves are quickly slowed to the thermal range where they can be more easily captured by a uranium or plutonium nucleus, and cause fertilization or fission, depending on the element and isotope.

@@sethapex9670 Sure heavy water absorbs significantly less neutrons than regular one does. But what I meant is that cross-section for *(gamma, n)* (i.e. presence of photoneutrons in the core due to deuterium nuclei splitting by gamma rays generated by some of the fission products) is relatively high. And considering a relatively large amounts of heavy water in CANDU reactors, amount of additional neutrons is quite significant

@@farqilion8747 I've not heard of photoneutrons before now, but I just looked into it and I suppose it makes sense that that may be likely.

einstein: _running_ fermi's gotta be doing something, right?! i need to weigh his samples!

3:32 you said "atoms are mostly made up of hollow space". It is incorrect to state that. The electron cloud is spread out over a large volume, with the highest probability of finding electrons near the nucleus and a lower probability of finding electrons further away from the nucleus. This results in the appearance of empty space within the atom. So while atoms do contain a significant amount of empty space, it is not accurate to say that they are "mostly made up of hollow space". :D

so the thorium guy couple year ago was right nice to know.

The US planes that dropped the atomic bomb on Hiroshima and Nagasaki (5:40) are drawn incorrectly: the stars on the wings should be white. Red stars were on the wings of Soviet aircraft.

did i miss something? wich part of the mass converts to energy?

A fan club, advocating for the use of thorium fueled reactors, began almost 20 years ago. It continues despite almost no interest from the government and private sectors. The fans are either clueless regarding this failure, or they believe this aspect should not be mentioned in their promotional pitches. The vast majority immerse themselves in eco-chamber groups where they can reinforce their love affair with this technology. Few have any interest in critical analysis such as looking into criticisms of the technology. Here are a couple of titles worth searching for. Thorium, Not The Nuclear Savior Claimed Thorium Fuel - No Panacea for Nuclear Power Many technology lovers often view nuclear energy as being a savior to deal with climate change issues. Unfortunately they tend to also be stuck with the view that we have 20-30 years to turn things around to the point where nuclear power can replace all our carbon emitting fossil fuel energy sources, including for mobile sources such as cars, buses, trucks, trains, ships and a slew of aircraft. These dreamers have become masters at excluding the following warnings from their consciousness. UN chief: World has less than 2 years to avoid 'runaway climate change' (TheHill) (Statement made over four years ago) IPCC report: ‘now or never’ if world is to stave off climate disaster (TheGuardian) One of the many waste products of the typical nuclear fusion process is the radioactive isotope plutonium-239 which has a half-life of a bit over 24,000 years which means particles of it remain a potential hazard for about a half-million years. In the U.S. creators of Spent Nuclear Fuel (SNF) waste were promised, in the 1950s, the creation of a deep geological repository. Seventy years later no such repository is on the horizon. The production of power has always taken priority and no one has been held accountable for the final waste disposal failure. A similar situation exist for all other countries that generate nuclear power since none of them yet has an operating deep geological repository.

I have to make it so it want to know that in which shape you have heated it in its original shape

I have a question if any one could help me with the answer: When the fuel rods are placed with Uranium in a power planet, how we introduce the neutron? the rods are sealed does it works with electric shock, or giving it heat? or how?

How can a charge-leds particle like neutron be accelerated to hit a nucleus?
