The rise of nanometers

The north wind blows and the snow is white.

The snow in Mobei this year was particularly heavy, and the snowfall was about two or three times that of previous years.

Deep in the Altai Gobi Desert, the Yugu base has been initially built. Huang Xiuyuan stood on the observation tower of the base through a stand-in robot.

The sky and the earth were completely white. Behind him was Wan Gaofeng, the base's chief researcher and one of the top researchers from the Hefei Plasma Research Institute.

"The auspicious snow heralds a good harvest. Mobei will definitely have a good harvest next year." After speaking, Huang Xiuyuan turned around and said, "Gaofeng, I saw your plan and it is indeed worth a try."

Wan Gaofeng immediately felt flattered and said with a smile: "The chairman has promoted me. I also conceived this plan on the shoulders of giants."

"Let's go see Yutani No. 1! Let's talk as we go."

The two took the elevator and arrived at the vast underground base.

This underground base was transformed from a former abandoned coal mine pit, with a depth of 247 meters, a length of 4.3 kilometers, and a width of 572 meters.

At this time, a huge equipment was built in the base. The equipment was very huge. There were two huge cylindrical equipment above and below, and four long strip-shaped equipment in the middle.

Huang Xiuyuan held a tablet with a design drawing on it. This was Tanggu No. 1 designed by the Wanfengfeng team.

The upper and lower cylindrical equipment is a positron stream emission system, which can form a cylindrical positron stream layer. The positron stream is sprayed downward from the upper injection port above. There is a set of internal and external electrostatic fields below, which can form an internal and external electrostatic field. A peak of the electrostatic field just forces the positron stream emitted from above into the annular trough of the electrostatic field.

Then it is sucked into the ring-shaped device below, and finally the sucked positron flow is sent back to the positron flow emission system above through the internal arc-shaped electrostatic field pipe.

The cylindrical positron flow layer can block the neutron flow ejected in all directions, and the remaining neutron flow is the neutron flow ejected upward and downward.

To solve the neutron flow ejected up and down, we must rely on the four rectangular positron emission systems. These four devices can form two horizontal plane positron current layers, which can be inserted into the cylindrical positron current layer to completely Block the neutron flow erupting inside.

As for the issue of nuclear fusion reactions, Wan Gaofeng's team gave up on tokamak devices and stellarators, and instead adopted an inertial confinement nuclear fusion solution, the so-called laser fusion.

The Shanghai Institute of Optics and Mechanics also sent hundreds of researchers to the Tanggu base to assist in the development of laser systems.

In the design plan of Wan Gaofeng's team, the nuclear fuel target pellet falls from above, and the superconducting magnetic levitation system at the bottom is used to suspend the target pellet in the middle of the positron current layer.

Then laser target shooting is started, and high-energy laser is used to ignite nuclear fusion. Since neutrons carry about 70% of the energy in the nuclear fusion reaction, after the neutrons are converted into high-energy protons, a large part will be sucked into the positron flow loop at the bottom.

Indeed, in the reaction, due to the design of Yutani-1, a relatively slender cylindrical positron flow layer is used, allowing most of the neutron flow to impact on the cylindrical wall, reducing the impact on the bottom and top.

Huang Xiuyuan pointed at the system and said:

"Gaofeng, you still have a small problem to pay attention to. Although the entire system is in a vacuum state, another problem has been ignored, which is that some high-energy protons can easily escape into the vacuum system."

Hearing this question, Wan Gaofeng also reacted: "The chairman is right, we need to consider this issue."

"There are not many other problems. The next step is to see the actual operation and find problems during operation."

"Chairman, what you said makes sense."

The design of Yutani-1 does not pursue the self-sustainability of tritium in nuclear fusion, because the raw material for nuclear fusion in the target pellet is deuterium, which is the DD reaction.

Although the DD reaction requires temperatures as high as 900 million degrees Celsius, in laser fusion, temperature and pressure are not a big problem.

In the Shenguang 3 system just completed this year, the laser focusing temperature has been increased to 1.46 billion degrees Celsius.

This is thanks to the CSi nanocrystal developed by Huang Xiuyuan, which increases the power of the Shenguang laser several times.

The Institute of Optics and Mechanics brought Shenguang laser technology to the Yutani base and applied it to the Yutani No. 1 system.

The DD reaction uses pure deuterium to carry out nuclear fusion reactions. The abundance of deuterium in the nature of blue stars is very high, so there is no need to worry about the source of nuclear fuel.

As for how to generate electricity, photovoltaic power generation panels, hot water steam turbines, and thermoelectric power generation systems are used to generate electricity in a composite manner.

In fact, the technical plan of Yugu-1 is very similar to Lao Maozi's underground nuclear fusion power station plan, but it is more refined, nuclear pollution has been suppressed to a minimum, and the problem of neutron exposure has also been solved.

The current problem is to build a prototype and study it as a technical verification.

"Gaofeng, when do you expect Yutani No. 1 to be completed?"

Wan Gaofeng thought for a while: "Around the beginning of 2015, Yugu No. 1 can complete the construction of the system."

Huang Xiuyuan nodded: "Yes! Thank you for your hard work."

In the underground base construction area, a large number of workers wearing exoskeletons operate various equipment and construct the entire set of equipment bit by bit.

After Huang Xiuyuan and Wan Gaofeng watched the construction of Tanggu No. 1, they went to the scientific research center of the base. He greeted all the researchers.

Then Wan Gaofeng led the research team to show him the simulated operation of Yugu-1 through the supercomputer simulation computing system.

In the three-dimensional image of the simulated calculation, a deuterium target pellet falls and is held firmly in the middle of the positron current layer. In an instant, 12 lasers emit high-energy lasers, focusing on the target pellet, and nuclear fusion reaction occurs.

A large number of neutrons, neutrinos, and photons exploded in all directions.

The neutrino penetrated at nearly the speed of light.

Photons shine on the photovoltaic power generation panel, and neutrons rush into the positron current layer and are quickly converted into protons. At the same time, the positrons annihilate some energy.

Then the positron flow carries high-energy protons into the bottom ring system, and then passes through the electrostatic field pipe, and finally conducts the heat energy out, that is, boiling water.

This is the preliminary operating model of the entire system.

Of course, this is only a preliminary simulation. During the actual operation, there must be many problems that were not unexpected during the design process.

After Huang Xiuyuan finished watching the simulation experiment, he thought for a while and said:

"Gaofeng, please communicate more with the Bazhong base. They also started building the Jinwu-1 last month. Their technical solution is similar to the Tanggu-1."

"Understood, I will definitely arrange this." Wan Gaofeng nodded.

The Jinwu No. 1 at the Bazhong base is based on the Tanggu No. 1 of the Wanfengfeng team, and then optimizes and designs its own solution.

The technical routes of both parties are essentially the same.

Huang Xiuyuan naturally wants both parties to communicate more and avoid working behind closed doors. Although the design of Tanggu No. 1 is perfect now, there will definitely be many problems when it comes to actual operation.

Moreover, the two current plans are obviously very large in scale, and miniaturization requires in-depth study by both parties.

Large-scale controllable nuclear fusion systems can only be used in fixed power stations on the ground. If they are to be used on ships and aerospace, miniaturization is a must.

After Huang Xiuyuan explained some things, he exited the virtual system.
