Chapter 392: Micro reactor

In the eyes of many people, it may be easier to make a model than to make a

complete thing.

After all, the model is so small, it doesn't take much material or much time.

But people who have really done a model, especially those who have done a 1:1

complete true reduction model, will tell you that sometimes it is more

difficult to make a model than to make it.

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

big thing small.

Although what Chen Xin is going to do is a miniature version of the nuclear

fusion reactor, the technical requirements are not lower than that of a real

large-scale reactor, and the requirements for parts processing accuracy are

even higher than those of a large-scale reactor. .

Although large-scale nuclear fusion reactors have strict requirements, the

tolerances allowed by large-scale equipment still have 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 equipment may not have an error

of ±0.5 on a scaled down model. The smaller the model, the more so.

Especially when you have to completely restore the structure and function of

large-scale equipment, the smaller the parts that require higher processing

accuracy, often the cost is many times exaggerated than the parts required by

large-scale equipment.

To give a simple example, in the existing nuclear fusion reactor technology,

the structure of the magnetic confinement nuclear fusion device that blocks

neutrons and plasma, prevents high-energy hydrogen ions from splashing, and

serves as a 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, neutrons can be blocked by processing the first wall to a certain

thickness, but when the model is reduced to a small scale, the thickness of

the first wall will become thinner. At this time, you want to continue to

maintain it. The blocking of neutrons places higher demands on itself.

Especially the first wall itself is a consumable. As the neutron bombards the

first wall, its surface will bubble!

Large-scale equipment can prolong its service life depending on its thickness,

and it is regularly replaced to prevent the entire first wall from being

penetrated.

But for small models, this is very terrible. After all, it is impossible to

say that the reactor will stop and change consumables after a few revolutions,

right?

This is also the reason why nuclear fusion devices are getting bigger and

bigger now. Because of technical reasons, the equipment can only be enlarged

to ensure the expected performance and 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 the table.

But in the end, he compromised with reality. He didn't really build an LED

lamp of the same type as an iron man, but a miniature reactor about one person

tall.

Although it is a micro-reactor with the same model, the structure and

functions of the nuclear fusion reactor that Chen Xin previously envisioned

are reproduced in this micro-reactor, and it can actually ignite and react,

and the reaction is controllable. Continuous and stable output of energy.

To achieve this, obviously there are very strict requirements on the materials

and processes for manufacturing this micro-reactor.

Fortunately, Chen Xin's drawings are products after the system has been

upgraded, and the tools he uses to make parts are also the robotic arms and

workbenches produced by the system, so there is no problem in terms of

machining accuracy and part quality. .

As for the materials used to manufacture this micro-reactor, Chen Xin chose to

obtain some of the core parts through system upgrades, while other parts were

requested by the national scientific research department. After obtaining the

materials, they would be processed with a workbench and a robotic arm.

In order to process these parts, Chen Xin not only made a small-scale upgrade

of his robotic arm, but also made an identical one in the office of the

barracks according to the workbench in his refuge, with drawing and scanning.

And upgrade function.

It is precisely because of this that Chen Xin was able to upgrade the heating

hub, energy tower and the drawings of this nuclear fusion reactor.

After the drawings were upgraded, not only the technical design was optimized,

but also some optimizations were made on the parts. The drawings that

specifically adjusted the direction of the upgrade have simplified the

requirements for parts and reduced the difficulty, and also allowed Chen Xin

to manufacture a micro reactor for verification. Technical ideas can be

realized.

Because it’s just a miniature reactor, it doesn’t require a lot of related

materials, and some rare materials are even used in very small amounts. So

when the helicopter came for the second trip and took away the heavy mecha

upgraded by Chen Xin, he was taken by him. The required materials have been

shipped.

It has to be said that after the aircraft regained its flight capability, at

least the transportation has become much more convenient.

After Chen Xin got the materials delivered by the air express, he directly

started the manufacturing of the micro-reactor, but because there were other

things to deal with, he basically went to deal with other things in the

morning, and then came to the military camp to manufacture the micro-reactor

in the afternoon. The parts of the reactor, until I go to sleep at

night~www.mtlnovel.com~ This kind of regular schedule is actually easy to be

traced 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 a barracks stationed

by an entire special force. He only walked to a camp less than a hundred

meters away when he went out. There were also combat teams who escorted the

entire process. There were still security problems. Enough protection.

Under such circumstances, Chen Xin's manufacturing of the micro-reactor was

also carried out smoothly. Various precision parts were manufactured and then

assembled.

Soon, the fission furnace part of this micro-reactor was completed.

Compared with fusion reactions, fission reactions are undoubtedly much easier

to control. Coupled with years of research on nuclear fission technology, a

miniature fission furnace is not 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 degree of enrichment of

nuclear fuel required, and the higher the control requirements for the

reactor, the difficulty and cost of manufacturing are also rising linearly.

And don't talk about conflating 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 electrical energy.

However, nuclear reactors use the energy released by matter during nuclear

reactions to generate heat and convert them into electrical energy. The two

are very different in terms of size and efficiency.

Chen Xin is able to manufacture isotope thermoelectric batteries, but this is

the first time to manufacture a small nuclear reactor.
