Doomsday Bunker Upgrade

In the opinion of many people, it may be easier to make a model than to build a complete thing.

After all, the model is so small that it doesn't require much material or effort.

But people who have actually made models, especially those who have done 1:1 full-real restoration models, will tell you that making a model is sometimes more difficult than making a real one.

Because it is easy to make a small thing big, but it is difficult to make a big thing small.

Although what Chen Xin wants to do is a miniature version of a nuclear fusion reactor, the technical requirements are not lower than that of a real large-scale reactor, and even the requirements for the machining accuracy of parts are even higher than that of a large-scale reactor. .

Although large-scale nuclear fusion reactors have strict requirements, the tolerance allowed by large-scale equipment still has a certain margin, but when you reduce the equipment proportionally, the original tolerance margin will also be reduced.

For example, on a large-scale device, an error of ±5 may not exist on a scaled-down model, and the smaller the model, the more so.

Especially when you want to completely restore the structure and function of large-scale equipment, the smaller the processing precision of the parts, the higher the cost is many times higher than the parts required by the large-scale equipment.

To give a simple example, in the existing nuclear fusion reactor technology, the structure on the magnetic confinement nuclear fusion device that blocks neutrons and plasma, prevents high-energy hydrogen ions from splashing, and serves as heat exchange in the future is called the first wall. In the selection of nuclear fusion reactor materials, the requirements for this first wall are extremely high.

In reality, the blocking of neutrons can be achieved by processing the first wall to a certain thickness, but when the scale of the model is very small, the thickness of the first wall will become thinner. At this time, I want to continue to maintain it. The blocking of neutrons creates higher requirements for itself.

Especially the first wall itself is a consumable, as the neutron bombards the first wall, its surface will foam!

Larger equipment can rely on thickness to extend service life, with regular replacements to avoid penetration of the entire first wall.

But for small models, this is very fatal. After all, it is impossible to say that the reactor will stop after a few revolutions to change the consumables, right?

This is also the reason why the nuclear fusion device is getting bigger and bigger. Because of technical reasons, the device can only be enlarged to ensure the expected performance, so as to realize the ignition of nuclear fusion.

However, what Chen Xin wants to do is just a model for verifying the technology. If it is not too exaggerated, he even wants to make a model that can be placed on the table.

But in the end, he made a compromise with reality. He didn't really build an LED lamp of the same style as Iron Man, but a miniature reactor about the height of one person.

Although it is a micro-reactor with the same model, the structure and functions of the nuclear fusion reactor that Chen Xin had previously imagined have been reproduced in this micro-reactor, and it can really ignite and react, and the reaction is controllable and can be Continuous and stable output energy.

To do this, it is obvious that there are very stringent requirements for the materials and processes used to manufacture this micro-reactor.

Fortunately, Chen Xin's drawings are the products after being drawn and upgraded by the system, and the tools he uses to make parts are also robotic arms and workbenches produced by the system, so there is no problem in terms of machining accuracy and quality of parts. .

As for the materials for making this micro-reactor, Chen Xin chose to obtain some of the core parts by himself through system upgrades, while other parts were obtained from the national scientific research department.

In order to process these parts, Chen Xin not only made a small-scale upgrade to his robotic arm, but also made an identical one in the office of the military barracks according to the workbench in his shelter, capable of drawing and scanning drawings. and upgrade function.

It is precisely because of this that Chen Xin was able to upgrade the heating hub, energy tower and the blueprint of this nuclear fusion reactor.

After the upgrade of the drawings, not only the technical design was optimized, but also the parts were optimized. The drawings that specially adjusted the upgrade direction simplified the requirements for the parts and reduced the difficulty, which also allowed Chen Xin to manufacture a micro-reactor for verification. The idea of ​​technology can be realized.

Because it is just a micro-reactor, there are not many related materials needed, and some rare materials are used very little. Therefore, when the helicopter came for the second trip to take away Chen Xin's upgraded heavy mecha, he also took him by the way. The required materials have been shipped.

It has to be said that after the aircraft has resumed its flight capabilities, at least it has become much more convenient in transportation.

Chen Xin started the manufacturing of the micro-reactor directly after he got the materials delivered by air express. However, because there are other things to be dealt with, he basically deals with other things in the morning, and only comes to the military camp in the afternoon to manufacture micro-reactors. The parts of the reactor go back to sleep at night.

In fact, to a large extent, this kind of regular work and rest is easy for people to figure out the trajectory of action. Whether it is kidnapping, assassination or tracking, it is easy to find flaws and opportunities.

But fortunately, Chen Xin spent more than half of his time in a barracks with a whole special force stationed there. He only went out to a camp less than 100 meters away, and the combat team escorted him all the way, so there are still security issues. adequate protection.

Under such circumstances, Chen Xin's fabrication of the micro-reactor was also carried out smoothly, and various precise parts were manufactured and then assembled again.

Soon, the fission furnace portion of the miniature reactor was complete.

Compared with the fusion reaction, the fission reaction is undoubtedly much better controlled. Coupled with the research on nuclear fission technology for many years, a miniature fission furnace is not that difficult to make.

Of course, this is not difficult for Chen Xin, for others, it is still a difficult thing.

Because the smaller the reactor, the higher the enrichment of nuclear fuel required, and the higher the control requirements for the reactor, the difficulty and cost of manufacturing are also rising.

And don't confuse radioisotope batteries with nuclear reactors, they are two completely different things in principle.

The radioisotope battery itself does not have a nuclear reaction, it just uses the radiation with heat energy released by the radioisotope to convert the heat energy into electricity.

However, nuclear reactors use the energy released by substances during nuclear reactions to generate heat and convert them into electricity. The two are vastly different in terms of size and efficiency.

Chen Xin was able to make isotope thermoelectric batteries, but this is the first time he has made a small nuclear reactor.
