Chapter 676

Everyone laughed at the boss's question. After Lei Tiantang finished asking, he also reflected that his question was really not very good. Nonsense? The country has made such great efforts, and infinite gravity group has come to the door to cooperate with each other. When both sides have sincere cooperation, there will be no less of them in the work.

It is so simple that how much effort you can make and how much you can gain. What's more, the great action of the state during this period has fully proved that we attach great importance to the experimental reactor of nuclear fusion reactor, and it is obvious to all whether or not we can make contributions.

So he shook his head and laughed a little, then said with a smile, "OK, I see. I believe you are ready for the work to be done. The specific ignition work should be carried out according to the plan!

Now let's talk about the super project we discussed with the leaders last time. What is the specific step of our work?

We have to know that after we have officially launched the construction of nuclear fusion reactor power station, the reactor needs a lot of deuterium and tritium. If we can't have a stable fuel supply, our work in the future will be difficult to do! "

The question raised by Lei Tiantang relates to an important cooperation topic discussed at the last meeting with the leaders, because the fusion reactor technology provided by Lei Tiantang is only the first generation of nuclear fusion reactor technology, that is, nuclear fusion reaction using deuterium and tritium as fuel.

Deuterium, the isotope of hydrogen (H), is also known as heavy hydrogen. The element symbol is usually D or 2H. Deuterium nucleus has a proton and a neutron, its relative atomic weight is twice that of ordinary hydrogen.

There is 0.02% deuterium in hydrogen, which is about one seventh of that in nature. Deuterium is used in thermonuclear reactions. It emits β - rays during fusion to form helium with mass number of 3. It is used as a tracer atom in chemical and biological research. Deuterium is called "natural fuel of the future".

Deuterium is abundant in seawater. There is about one deuterium atom in every 6500 hydrogen atoms in seawater, and the total amount of deuterium in seawater is about 45 trillion tons. The fusion energy released by the complete fusion of deuterium in each liter of seawater is equivalent to the energy of 300 liters of gasoline fuel. According to the world's energy consumption, the fusion energy of deuterium in seawater can be used for tens of billions of years.

Tritium can be made from lithium. There are mainly two isotopes of lithium-6 and lithium-7. After absorbing a thermal neutron, lithium-6 can be converted into tritium and emit energy. Lithium-7 needs to absorb fast neutrons to become tritium. Although the reserves of lithium on earth are much less than deuterium, there are more than 200 billion tons.

Using it to make tritium is enough to use deuterium and deuterium fusion. Therefore, nuclear fusion energy is an inexhaustible new energy.

However, there is a problem here. We should know that there is no problem in the preparation technology of tritium. It is really hard to extract tritium from seawater. Modern tritium production is generally produced by bombarding lithium with neutrons in fission reactors!

Does this affect the fission reactor efficiency? In fact, if you don't use these neutrons, you have to absorb them with deceleration agents, such as heavy water or early graphite. Isn't it waste to use them to produce tritium?

The nuclear fusion reactor is not to say that it can replace the nuclear fission reactor immediately. The state has invested a lot in the nuclear fission reactor. After building so many nuclear fission power stations, we can't say that the nuclear fission reactor will be abandoned? That's not too wasteful!

It can be used to produce tritium while supplying power to the power grid, so there is no problem in this aspect of production.

The only fuel that needs to be extracted from sea water is deuterium. Lei Tiantang asked's super project is about the extraction of deuterium. He does not lack these nuclear fuels. Whether he extracts directly from the sea water with his own ability, or he deliberately selects these important substances when he devours so many substances in the universe, all of which can make him have an amazing number All kinds of nuclear materials.

However, there is no problem for him to use these materials privately. If he wants to use them, he can't. how can he explain the source of these nuclear fuels?

Therefore, when designing the nuclear fusion reactor, he and Kuafu considered this problem, and finally designed a set of technical means to extract deuterium from seawater. This technology was also provided to the laboratory of the energy company for verification. Of course, the state knew the existence of this technology.

Since there is no problem with the technology, we should start to prepare for this work. At the last meeting, the leader discussed with Lei Tiantang about the development of a super engineering project to extract deuterium from seawater. Of course, the project was submitted by infinite gravity group.

"Boss, the state is more active than us in this matter. Now the site selection has been completed and the technology has passed the strict audit. There are no problems in our company, so we have officially started the construction!

However, due to our company's technology is too mature, so our current super project is not a simple sea water pre deuterium single project, but a comprehensive super engineering!

The project site is located in Huangdao, in order to send the by-product fresh water produced by using our seawater extraction technology to surrounding areas that are short of water all the year round. Special channels will be built to transport these fresh water to further places, even to desert areas, so as to contribute to the work of planting trees and preventing sand there!Therefore, the government is active in this respect. After all, the lack of freshwater resources in our country is not just a talk! And our technology, we also think that it is too wasteful to use it to extract deuterium from seawater. The better use should be desalination engineering!

The project we are going to build this time is also going to use nuclear fusion reactors as energy. In this way, the cost of desalination will be reduced to a very low level. It is self-evident what changes this will bring to our country. " Jiang Yuting replied with a smile.

Jiang Yuting's answer also makes you understand why the state attaches so much importance to the company's nuclear fusion reactor project, because just a branch technology in this project can become a solution to the major development problems of the country!

We should know that China is really a country with serious drought and water shortage. China's total freshwater resources is 2800 billion cubic meters, accounting for 6% of the global water resources, ranking fourth in the world after Brazil, polar bear and maple leaf countries.

It seems to be OK. However, China's per capita water resources is only 2300 cubic meters, which is only 14% of the world average. It is one of the countries with the poorest per capita water resources in the world. However, Huaxia is the country that uses the most water in the world.
