The world of shelter under the glacier - Chapter 239 Nuclear fusion! (Please subscribe)
Seeing that Chu Feng was unmoved, Li Fugui gritted his teeth and said:
“elder brother.”
“I’ll tell you some more news.”
“What? Look how mysterious you are.” Chu Feng said amusedly.
“The latest revelation from the Nuclear Fusion Research Institute is that it is a face-saving project and a beautiful dream.”
“No way?”
Chu Feng said in surprise.
The so-called nuclear fusion, simply put – that is, under extremely high temperature and pressure, the collision of atomic nuclei causes polymerization, thus releasing a large amount of energy.
and!
The sun itself is a huge nuclear fusion reactor. Under a strong pressure of 240 billion, hydrogen elements collide at a high temperature of 15 million, resulting in a nuclear fusion reaction.
But Aquamarine doesn’t have such strong pressure!
Human beings cannot create such a high-pressure environment, let alone materials that can withstand such pressure.
Therefore.
Scientists can only work hard on high temperatures.
Various studies have shown that the test temperature of controllable nuclear fusion must exceed at least 100 million degrees, and even 200 million degrees is the basic reaction condition for nuclear fusion.
After understanding these basic principles and thinking about it, I know how to design a fusion device.
It’s very simple.
Just put a bunch of nuclear fusion raw materials, deuterium and tritium gas, together and heat them up!
Why his two brothers?
Not deuterium-deuterium, not hydrogen-hydrogen, and not helium fusion?
because……
His two brothers are the easiest to fuck… No! Just because they have the lowest fusion conditions and the lowest requirements!
Easiest to implement.
That’s all!
So the question is, what is used to put hundreds of millions of degrees of deuterium and tritium together?
at present.
There are two routines for global nuclear fusion generating devices.
The first routine is to use N-beam lasers to surround a point from all directions, and instantly squeeze the atomic nuclei together, commonly known as “laser target shooting” – the scientific name is “inertial constraint”.
This twists the deuterium and tritium together, but cannot continue to add materials.
so.
Before the end, only the bald eagle dared to play so boldly and without scruples!
Without him…
Too much money and heartburn!
The second trick: magnetic confinement—that is, using a magnetic field to twist the nuclei together.
At high temperatures, the connection between the nucleus and the electrons is broken, the electrons leave the nucleus, and the remaining nuclei are called “plasma”, which is positively charged and constrained by a magnetic field.
The most famous one is the tokamak device.
——This is also the key direction of Longguo’s nuclear fusion!
Things are looking good so far.
pity.
Scientific research is similar to flirting with girls.
The theoretical conditions have been discussed previously, and we are about to start a family hand in hand.
But there are unforeseen circumstances, and scientific research will always take 50 years.
In the world of flirting with girls, Fusion belongs to the top class of cool girls, and counting, Magnetic Constraint is also an experienced one.
After more than half a century of flirting with girls at Fusion, the girls at Fusion are always reluctant to leave.
There is a universal truth – boys never know how they made girls angry.
Do you think you can attract girls by putting hundreds of millions of degrees of deuterium and tritium together?
too naive! !
The shape of plasma is similar to that of gas. In addition to traditional fluid mechanics, there are also very complex electromagnetic interactions.
Among the many girls in physics, fluid mechanics is the least popular. The routine is too deep!
Fusion is “fluid mechanics” + “electromagnetism” + “extreme conditions”. Its behavior can be described as weird. It was originally going well, but with a little disturbance, it suddenly turned upside down.
All the conditions are obviously met, but she just doesn’t fuse.
At the same time, another universal truth is verified – it’s all the boys’ fault if they can’t seduce girls.
If you don’t cause that “little disturbance”, wouldn’t it be fine?
You think I do!
The product of deuterium and tritium fusion is helium. Helium is a “disturbance”, and the concentration of helium is increasing. This is a very serious disturbance to the entire system.
besides.
Donut-style heating devices can also affect stability.
Can a top spin by itself without being whipped by a whip?
This skill is terrifying!
It needs to be whipped, but it cannot affect the trajectory of the top.
thereby–
The first problem arose with tokamak.
Plasma stability!
Under such a complex magnetic field, it is difficult for the separated plasma to operate stably for a long time.
The longest simulation running time in the Longguo Research Institute was only 102 seconds!
completely!
Shoot in seconds!
If this problem is not solved, it will not be put into use at all!
also.
Even if you understand the fusion girl’s thoughts, can you afford to give her a limited edition donkey bag?
The “first wall of fusion” is the inner wall that directly faces the fusion. This is a temperature of hundreds of millions of degrees and a large amount of neutron radiation. It is equivalent to adding a coat to the sun!
It’s as difficult as climbing to the sky!
Under such extreme conditions, atoms are easily displaced when bombarded. The strength of the material depends on the arrangement of the atoms. No one can withstand such abuse, and the material properties will soon deteriorate.
A few more technical details.
A strong magnetic field requires a strong current, so only superconducting materials can be used.
The working environment of superconducting materials must be at least minus 200 degrees liquid nitrogen, or even colder liquid helium.
These two guys, one works at minus 200 degrees Celsius, and the other is at hundreds of millions of degrees above zero. Can you tell me, is it easy to serve them both at the same time?
all in all.
The main difficulties in nuclear fusion are:
One is the material issue.
Second, the plasma floats too much and cannot operate stably.
After briefly explaining the difficulties of Tokmak, the little fat man Li Fugui said:
“before.”
“Our Dragon Kingdom cannot solve the material problem, so the Nuclear Fusion Research Institute attributes all problems to this.”
“But now that we have the Universal Stone, the material’s performance has greatly increased!”
“But we still can’t achieve nuclear fusion, and we’re stuck on the running time.”
“After several consecutive tests, it used to be 102 seconds, and now it is 112 seconds. This time is not enough for me to rub once… Do you think we can count on these people?”
“The Great Elder is furious about this!”
“Another 50 years?”
“Do we still have 50? We may not have it in 10 years.”
Li Fugui said worriedly:
“Our Feihe base has only 300 tons of enriched uranium in reserve, and we have consumed 25 tons in the past year. Such tight savings will only last 10 years at most, and we will run out of power!”
“Except for the three major super bases, other bases are in a similar situation.”
“you say.”
“Now who dares to go to great lengths to plant crops or even raise some cattle and sheep?”
“No!”
“No base dares to do this!”
“so.”
Li Fugui said seductively: “Brother Lin, hurry up and buy the bottom.”
“A thousand pieces of meat per kilogram, how expensive is it?”
“Not expensive!”
“after.”
“It will only be more expensive. I wouldn’t be surprised if it weighs tens of thousands of pounds!”
“Now you can buy as much as you have!”
“Don’t miss it!”
“If I hadn’t taken care of the emotions of other bases, I would have bought the goods.”
No.
Anyway, isn’t this money issued by Feihe?
Gone.
There is no need to even print money, it is just a matter of changing a string of codes.
As for the issue of economic collapse, prices haven’t collapsed now – they have collapsed long ago!
Today’s prices are changing every day!
——This is a true portrayal of the current doomsday.
