Doomsday Bunker Upgrade Chapter 390: Microreactor

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 take much material and effort.

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

Because it's easy to make a small thing big, but it's hard 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 large-scale reactor, and even the requirements for the machining accuracy of parts are even more demanding in large-scale reactions. above the furnace.

Although the requirements for large-scale nuclear fusion reactors are strict, 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, an error of ±5 on a large-scale device may not have an error of ±0.5 on a scaled-down model. The smaller the model, the better.

Especially when you want to completely restore the structure and function of large-scale equipment, the smaller the part, the higher the machining accuracy is, 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, this first wall has extremely high requirements.

In reality, it is possible to block neutrons 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. Continuing to maintain its blocking of neutrons creates higher requirements for itself.

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

Large equipment can rely on thickness to extend service life, replace it regularly to avoid penetration of the entire first wall.

But for a small model, this is very bad, after all, it is impossible to say that the reactor will stop after a few turns 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 technology. If it is not too exaggerated, he even wants to make a model that can be placed on a table.

In the end, however, he made a compromise with reality and didn't actually build an LED light of the same style as Iron Man, but a miniature reactor about the height of a person.

Although it is a micro-reactor with the same model, the structure and function of the nuclear fusion reactor that Chen Xin had previously imagined are reproduced in this micro-reactor, and it can actually ignite and react, and the reaction can be It can continuously and stably output energy.

To do this, there are obviously very stringent requirements for the materials and processes used to manufacture this miniature reactor.

Fortunately, Chen Xin's drawings are 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 in terms of machining accuracy and parts quality, it is No problem.

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 country's 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 barracks office according to the workbench in his shelter, with drawings Draw, scan and upgrade capabilities.

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 adjusted the direction of the upgrade were simplified and the difficulty of the parts was simplified, which also allowed Chen Xin to make a The idea of ​​a microreactor verification technology can be realized.

Because it's just a miniature reactor, it doesn't require a lot of related materials, and some rare materials are used in very small amounts, so when the helicopter comes for the second trip and pulls away Chen Xin's upgraded heavy mecha, By the way, I brought the materials he needed.

It has to be said that after the aircraft regained its ability to fly, at least it became much more convenient in transportation.

Chen Xin started the fabrication of the micro-reactor directly after receiving the materials delivered by air express. However, because there are other things to deal with, he basically deals with other things in the morning and only arrives in the afternoon. The military camp manufactures the parts of the micro-reactor, and goes back to sleep at night~IndoMTL.com~ This kind of regular work and rest is actually easy to find out the trajectory of the movement to a large extent. Whether it is kidnapping, assassination or tracking, it is easy to find flaws and opportunities.

Fortunately, Chen Xin spent more than half of his time in the military camp where a whole special force was stationed. When he went out, he only walked to the camp that was less than 100 meters away, and the combat team was closely escorted and protected throughout the whole process. The problem is still adequate.

Under such circumstances, Chen Xin's fabrication of the micro-reactor also proceeded smoothly, with various precision parts being fabricated and then assembled.

Soon, the fission furnace portion of this miniature reactor will be complete.

Compared with the fusion reaction, the fission reaction is undoubtedly much easier to control. 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 skyrocketing.

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

The radioisotope battery itself has no nuclear reaction, it just uses the radiation with heat energy released by the radioisotope to convert the heat energy into electricity.

Nuclear reactors use the energy released by matter during nuclear reactions to generate heat and convert it into electricity. The two are vastly different in 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.
