Chapter 390 Micro Reactor
In the eyes of many people, it may be much easier to make a model than to create something in full.
After all, the model is just a little small, and it doesn’t take much material or time.
But people who have really made models, especially those who have made 1:1 completely real-life restoration models, will tell you that sometimes it is more difficult to make a model than to do it.
Because it is easy to make a small thing bigger, but it is difficult to make a big thing smaller.
Although Chen Xin is going to do a miniature nuclear fusion reactor, the technical requirements are no lower than the actual construction of a large reactor, and even the requirements for parts processing accuracy are higher than those for large reactors.
Although large nuclear fusion reactors are strictly required, the allowable tolerances for large equipment still have a certain margin. However, when you reduce the equipment by equal proportions, the original tolerance margin will also be reduced.
For example, if the error of ±5 on large equipment or on a model with equal scale reduction, the error of ±0.5 may not be present, the smaller the model, the more this is.
Especially when you want to completely restore the structure and functions of large equipment, the smaller the parts, the higher the machining accuracy requirements, the more expensive the parts are, many times more expensive than those required by large equipment.
To give a simple example, in the existing nuclear fusion reactor technology, the magnetically constrained nuclear fusion device blocks neutrons and plasmas, prevents high-energy hydrogen ions from splashing, and future heat exchange is called the first wall. In the selection of nuclear fusion reactor materials, the first wall has extremely high requirements.
In reality, the barrier to neutrons can be achieved by processing the first wall to a certain thickness, but when the model scales to a very small scale, the thickness of the first wall will become thinner. At this time, if you want to continue to maintain its barrier to neutrons, you will have higher requirements for it.
Especially the first wall itself is a consumable, and as the neutron bombards the first wall, its surface will bubble!
Large equipment can be relied on its thickness to extend its service life and replaced regularly to prevent the entire first wall from being penetrated.
But for small models, this is very fatal. After all, it is impossible to stop and change consumables after a few turns, right?
This is also the reason why nuclear fusion devices are getting bigger and bigger now. Due to technical reasons, the equipment can only be larger to ensure the expected performance and achieve the ignition of nuclear fusion.
However, what Chen Xin wanted to do was just a model for verifying technology. If it wasn't too exaggerated, he would even want to make a model that could be placed as big as a table.
However, in the end, he compromised the reality and did not really build an LED light of the same style as Iron Man, but a miniature reactor about one person tall.
Although it is a mini reactor like a model, the structure and functions of the nuclear fusion reactor that Chen Xin had previously imagined were reproduced on this mini reactor, and it can really ignite and react, and the reaction is controllable, and can continuously and stably output energy.
To do this, it is obvious that there are very strict requirements on the materials and processes for making this micro reactor.
Fortunately, Chen Xin's drawings are products after drawing and upgraded through the system, and the tools he used to make parts are also robotic arms and workbenches produced by the system. Therefore, there is no problem in terms of machining accuracy and part quality.
As for the materials used to make this micro reactor, Chen Xin chose some of the core parts to obtain by himself through system upgrades, while the other parts were asked to obtain the materials and then processed with a workbench and a robotic arm after obtaining them.
In order to process these parts, Chen Xin not only made a small upgrade to his robotic arm, but also made another identical piece in the office of the military camp according to the workbench in his shelter, with drawings, scanning and upgrading functions.
It is precisely because of this that Chen Xin was able to upgrade the heating hub, energy tower and drawings of this nuclear fusion reactor.
After the drawings were upgraded, not only did the technical design be optimized, but also some optimizations were made to the parts. The drawings that specifically adjusted the upgrade direction simplified and reduced the difficulty, and Chen Xin's idea of manufacturing a micro reactor verification technology can be realized.
Because it is just a micro reactor, the relevant materials do not require a lot, and some rare materials are used very little. So when the helicopter came to take away the heavy mecha that Chen Xin had upgraded, he also transported the materials he needed.
It has to be said that after the plane recovers its flight capabilities, at least it has become much more convenient in transportation.
After receiving the materials delivered by the air express, Chen Xin started the manufacturing of the micro reactor directly. However, because there are other things to be dealt with, he basically handles other things every morning and only comes to the military camp to make parts of the micro reactor in the afternoon until he goes back to bed at night.
This regular routine is actually very easy to understand the trajectory of action, and it is easy to find flaws and opportunities whether it is kidnapping, assassination or stalking.
Fortunately, Chen Xin spent more than half of his time in a military camp with a whole special forces stationed. He went out to a camp less than 100 meters away, and there was also a combat team who was intimately escorted the entire process, so there was enough security issues.
Under such circumstances, Chen Xin's manufacturing work of the micro reactor was also carried out smoothly, and 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. In addition to the research on nuclear fission technology over the years, a miniature fission furnace is not something that is difficult to make.
Of course, this is not difficult for Chen Xin, but for others, it is still a very difficult thing.
Because the smaller the reactor, the higher the enrichment of nuclear fuel required, and the higher the control requirements for reactors, the difficulty and cost of manufacturing are also rising sharply.
And don’t talk about confusing radioactive isotope batteries with nuclear reactors, the two are two completely different things in principle.
Radioactive isotope batteries themselves have no nuclear reactions. They just use the rays with thermal energy released by radioactive isotopes to convert heat energy into electrical energy.
However, nuclear reactors use the energy released by substances during nuclear reactions to generate heat and convert it into electricity. The two are very different in terms of volume and efficiency.
Chen Xin was able to manufacture isotope temperature difference batteries, but this is the first time that he built a small nuclear reactor.
