Safety is the biggest aspect of molten salt reactors, but there is also an even more attractive advantage of molten salt reactors, which is energy efficiency. Pen & Fun & Pavilion www.biquge.info

During the fission process, thorium will fission into more fragments, which means that more energy will be produced during the fission process, the energy efficiency is much higher than that of existing reactors, and most of the fission products are light cores.

Since the half-life of radioactive light nuclei is shorter, this means that the disposal of radioactive waste will become easier.

The storage time of radioactive waste will be shortened from the current tens of thousands of years to hundreds of years.

At the same time, as mentioned above, the molten salt reactor has a "hemodialysis" system, so the fission waste will be extracted from the molten salt online in time and will not interfere with the operation of the core, which can ensure that more than 99% of the thorium added to the molten salt can be consumed in the fission reaction, while the existing reactor, the utilization rate of uranium-235 is only a few percent.

Having said so much, some people have to ask, why is it that no one uses such a good thing? Bragging, right?

In fact, there are two sides to everything, just like fusion energy, the theoretical advantages cannot be said for a few days and nights, but over the years, there has been no promising progress in fusion energy.

Similarly, the inherent shortcomings of molten salt reactors also make it unsuitable for widespread use at present.

The first is the corrosiveness of molten salt, fluoride is a very corrosive substance, extremely corrosive to metal pipelines, and after heating, fluoride is even more corrosive, which is a great challenge for reactor materials.

The second is the control of the molten salt state, in order to maintain the operation of the reactor, it is necessary to ensure the fluidity of the molten salt, and it is necessary to keep the whole circuit at a high temperature at all times, which is difficult to achieve if the system design is too complex.

In addition, if the temperature of some pipes decreases due to a fault, and the molten salt solidifies and blocks the pipes, the core will be shut down due to the heat being unable to conduct out and overheating.

Although there is no risk, in industry, who can tolerate a power generation equipment that is often lying on its stomach?

Of course, compared with the safety performance and power generation, all kinds of shortcomings are tolerable, so Mo Ye chose this kind of reactor to build.

And the construction technology of this reactor is not very high-end, but it is not so simple, the main thing is the construction materials and reasonable design.

In fact, the British have lagged behind in this regard, but the Americans are in the forefront, and this kind of reactor was first proposed by the Americans.

The molten salt reactor was first proposed in the 60s of the last century, and the Oak Ridge National Laboratory in the United States completed the construction and operation of the world's first molten salt reactor in 65 years.

The concept of molten salt reactors in the United States today was also proposed on the basis of the experimental reactor at Oak Ridge National Laboratory.

And the energy company mentioned at the beginning, it's likely that they just modernized the age-old concept of molten salt piles in order to raise money and then delve into it.

As for China, in the field of molten salt reactors, the Chinese Academy of Sciences began research many years ago and has achieved a lot of results.

Moreover, the Chinese Academy of Sciences has planned to build China's first molten salt reactor in the next ten years.

Compared with Western countries, which mainly rely on corporate financing for research, China's nuclear energy research is supported by national strength, and to a certain extent, nuclear energy research also reflects the national will.

It is worth mentioning that after decades of uninterrupted research, in recent years, China's achievements in nuclear energy research have appeared frequently, the fourth generation of nuclear power technology has long been ahead of the world, the future energy revolution, is very likely to sprout in China, and led by China.

It is also with so much accumulation that Mo Ye will be so confident in building this kind of reactor.

Of course, for the first time, Mo Ye could only accumulate experience, and now that the external main building has been completed, as long as enough thorium and a manufactured neutron moderator are provided, the reactor can be started.

And this process may not be easy for others, but for Mo Ye, it is not difficult at all.

The first is the extraction of thorium, which Mo Ye has recently obtained, although it is not much, but it is enough to be used recently.

Thorium is a radioactive metallic element with a steel-gray luster, a soft texture, and a more reactive chemical nature.

Thorium is generally used to make alloys to improve the strength of the metal; Burning thorium dioxide emits a strong white light, so it used to be used as a white-hot gauze for gas lamps.

Thorium decays to store much more energy than uranium, coal, oil and other fuels combined, and thorium contains much more than uranium, making thorium a promising energy source.

Thorium is also a common raw material for the manufacture of advanced lenses, and the nuclear fuel - uranium-233 can be obtained by bombarding thorium with neutrons.

Thorium is widely distributed in the earth's crust and is a promising energy material, and there are some of these raw materials in the rare earth mines north of Moxie Village.

Generally, thorium is found in minerals in the form of compounds (such as monazite and thorium), which are usually associated with rare earth metals, so Mo Xie is lucky enough to extract some.

Natural thorium ore has a lot of stock in nature, and it is not as difficult as uranium ore, because monazite is one of the main minerals of rare earth metal ores, often containing thorium, zirconium, etc.

Because monazite fluoresces bright green when exposed to ultraviolet light, it is easily recognizable.

Of course, it is also radioactive because it contains uranium, thorium, and radium.

However, it is mainly produced in pegmatites, granites and their related post-period deposits, so it is not so easy to extract.

For Mo Ye, this is not a problem, and at the same time, when he extracts thorium ore, he can also get a large number of rare minerals.

This is due to the fact that monazite has a number of symbiotic minerals, including cerium fluorocarbonite, yttrium phosphate, spodumene, zircon, beryl, apatite, rutile, ilmenite, fluorite, barite or niobite.

Of course, the extraction of thorium is not complete, and it is also necessary to dissolve thorium in the coolant, because the reaction material of the molten salt reactor is thorium dissolved in the coolant.

This point, if it is done manually, or in a laboratory, it is not very simple, but it is too easy for Mo Ye to use a super biological detector to complete the dissolution.

Of course, even if you get a solution, you still need a reactor core, but the reactor core in a molten salt reactor is a neutron moderator made of graphite blocks, and graphite is everywhere, so this is easier to solve.

The next step is to dissolve the thorium in the coolant with liquid fluoride salts, which is not difficult to complete, and once this step is completed, the molten salt reactor is ready to operate.

The liquid fluoride salts that dissolve the nuclear fuel can be piped into the core from below, and the reactor is completed as long as the reactor material is cleared and there are no leakage problems.

Of course, the reactor provided the heat, and it was also necessary to build a thermal power station, and at this point, any engineering team would be able to do it.

In this, as long as the problem of the main body of the molten salt reactor building is solved, this molten salt reactor is synonymous with safety, convenience and practicality, so such a reactor must not be let go.

Mo Xie's plan is very simple, and now he lacks everything, so he can only build a reactor step by step using the existing technology.

As long as there is enough energy, the high-temperature and high-pressure furnace can be put into use, and with the high-temperature and high-pressure capacity to refine various metal materials, which in turn can improve the safety performance of the reactor.

At this point, technology can be recycled, elevating technologies and materials to a very high level.

Mo Xie not only has the existing technology in his hands, but also the higher-level technology stored in this super biological detector, as long as he lays a good foundation and smoothly promotes the progress of science and technology, it is not very difficult.

"A journey of a thousand miles begins with a single step, and everything can only be done step by step!" Everything started to be completed step by step, which made Mo Ye's mood a lot better.

However, there are still too many restrictions in the country, so the underground base he built in his hometown can only go so far, and after accumulating experience here, the upgraded version can't continue to stay here.

The country is too strong, which has caused great restrictions on the development of individuals, because Mo Ye is an uncontrollable factor, and for a big country, such a factor as him will definitely be resolutely eliminated.

And Mo Ye knows this very well, so in his plan, it is just accumulation at home, and there is a broader world abroad for him to gallop, so he naturally does not want to be bound by domestic rules and regulations.

Afraid of being noticed, so Mo Ye did everything secretly, treasure hunting was secret, building a nuclear power plant was secret, and even the power station was running and connected to the grid, which was also done secretly.

On this day, Mo Xie walked out of the laboratory, and at this time, all his plans came to an end, even the high-temperature and high-pressure furnace was experimented once, and many detailed records were obtained.

Today, Mo Xie dismantled all the things that could be dismantled and put them in the space, so he easily walked out of the laboratory.

Now there is only one power plant left in the laboratory, although there is also a molten salt reactor, but this kind of reactor with good safety performance, Mo Ye is not afraid of being seen.

"Huh? What are you doing here? As soon as he walked out of the underground passage, Mo Ye saw a large group of people blocking the door.

"Mo Xie? I knew you were here, what's the matter, you're a military forbidden place? Still won't let us in? When Liu Yuanjun saw Mo Ye, he was sneering.

Mo Xie smiled and said, "What, Uncle Liu wants to come into my house to have a look?" Is that why we can visit your house at any time? ”

"This is your home?" Liu Yuanjun sneered.

Mo Xie said: "It's much more important than my house, if you go to my house, I definitely can't shut you out, but here, not everyone can go in!" ”

"I know you're here, doing something unseemly!" Liu Yuanjun said.

"Don't talk nonsense with him, let's go inside!"
