Siheyuan: First-class Merit at the Start

As for the dust on his body? That was caused by the various smoothbore guns fired from that 125mm smoothbore gun.

The billowing smoke and dust raised by the smoothbore cannon fed everyone half-full.

But no one cared about this tiny detail.

Everyone was stunned by its tremendous power.

It took a long time for me to recover until the fire test was over.

If Li Polu wanted to discuss the next project with everyone, these people would probably have to stay in the observation room for a while.

Came to a meeting room that was guarded by layers of security.

After everyone sat down, Li Bolu pretended to take out a thick stack of information from the safe.

It was then distributed to the industry leaders present.

Huang Zu, Qian Qiang and others hadn't even picked up the information to read it carefully, but they were already shocked just by seeing the title on the cover.

Controlled Nuclear Fusion Project Plan

Qian Qiang was stunned. How could they be able to study such a thing right now?

You have to know that it is less than a year since the first atomic bomb exploded.

As for the hydrogen bomb? It's still theoretical!

On this basis, is it really appropriate to study controlled nuclear fusion now?

Everyone's heart couldn't help but beat a little nervously.

The so-called controlled nuclear fusion refers to the process of artificially controlling light atomic nuclei (such as deuterium and tritium, isotopes of hydrogen) to undergo polymerization reaction under extremely high temperature and pressure conditions to generate heavier atomic nuclei and release huge amounts of energy.

Matter is made up of molecules, molecules are made up of atoms, the nucleus in an atom is composed of positively charged protons and uncharged neutrons, and the nucleus is surrounded by electrons equal in number to protons.

Under ultra-high temperature and ultra-high pressure conditions, the nuclei of light atoms (such as hydrogen isotopes) can overcome the electrostatic repulsion between each other, causing the nuclei to aggregate with each other, generating heavier nuclei and releasing huge amounts of energy.

The easiest fusion reaction to achieve in nature is the fusion of hydrogen isotopes, deuterium and tritium, a reaction that has been going on in the sun for about 50 billion years.

The enormous pressure and temperature of up to 1500 million degrees Celsius inside the sun allow hydrogen nuclear fusion to proceed uninterruptedly.

On Earth, since it is impossible to obtain such a huge pressure, the only way to make up for it is to increase the temperature. To achieve hydrogen nuclear fusion, a temperature of nearly 100 million degrees is required.

There are many challenges in achieving controlled nuclear fusion, the most important of which is how to confine the reactants with temperatures as high as hundreds of millions of degrees Celsius within a certain space and make them react stably and continuously.

There are two main common solutions.

One is magnetic confinement fusion: using magnetic fields to confine charged plasma, allowing it to run at low density for as long as possible to achieve nuclear fusion energy gain.

The tokamak device is a major method of magnetic confinement fusion. It is donut-shaped and confines fusion plasma inside by designing a magnetic field.

For example, the EAST of later countries and the ITER project of international cooperation are both tokamak devices.

However, the ITER project faces many technical challenges during its construction and requires solving a large number of problems.

The second is inertial confinement fusion: also known as laser fusion, which stores deuterium and tritium fuel in a tiny target pellet, uses multiple beams of strong lasers or converts them into X-rays to ablate the recoil-compressed fuel target pellet, and achieves high-density nuclear fusion in a short time.

After one hundred millionth of a second, the combustion stops due to the inertia of the fuel exploding outwards.

This scheme was later adopted by the National Ignition Facility of the Lawrence Livermore National Laboratory in the United States. In the experiment, the device achieved for the first time a net energy gain of more than 54% of the input energy in fusion energy, which was an important breakthrough for mankind on the road to achieving controlled nuclear fusion.

Of course, high difficulty usually also means high rewards.

Controlled nuclear fusion has many advantages, such as:

Abundant fuel sources: Deuterium is abundant in the Earth's seawater, with a reserve of up to 40 trillion tons. If all of it is used for fusion reactions, the energy released will be enough for humans to use for tens of billions of years. Although tritium is rare on Earth, it can be obtained through the conversion of lithium.

Clean and pollution-free: The reaction products are mainly neutrons and helium without radioactive pollution. It does not produce greenhouse gases or products with long radioactive periods, and is very environmentally friendly.

High safety: Once a problem occurs in any link, the fuel temperature drops and the fusion reaction will automatically terminate, and accidents like nuclear fission nuclear power plants will not occur.

If it is commercialized, it will provide mankind with a nearly unlimited, clean and safe new energy source.

While being able to effectively solve the energy crisis, it can also promote another revolution in science and technology.

Everyone looked at each other, and for a moment, no one knew what to say.

After all, they haven't even figured out fission yet, so how can they have the time to conceive the structure of fusion!

However, after seeing the confident look on Li Polu's face, they suppressed their curiosity and looked through the information Li Polu sent them.

After all, no matter how curious you are, you have to understand the principle of this thing before you can discuss it!

Otherwise, if we can't even raise a question, what's the point of discussing it?

At the beginning, it was fine. It was just about explaining the principles of controlled nuclear fusion and the possible benefits after its realization.

Similar to an outline, or overview.

But when they turned the page again, everyone's eyes lit up.

Huh? There's something!

Everyone present here is an authority in various fields of physics, so naturally they can see the meaning of the various formulas at a glance.

The more I watch, the more excited I get. The more I watch, the more thrilled I get.

Because they always feel that if they follow the steps in the plan, this thing may really succeed.

After reading the information, the old men did not rush to ask Li Polu questions, but picked up their notebooks and started writing on them with pens, their eyes revealing enthusiasm.

Li Polu couldn't help laughing when watching this scene.

What a lovely group of people!

These old guys are really serious.

What he has come up with now is just an outline, and the important thing is just a core formula.

But for this formula, they still need to verify it before proceeding to the next step.

"that....."

As soon as Li Polu opened his mouth, he was interrupted.

"Don't make a fuss. Let's finish checking the formula first before discussing the feasibility."

Seeing this, Li Bolu couldn't help but shook his head.

Then he whispered something to Wu Feiyang, and the two of them stood up and left together.

He took Wu Feiyang to eat lunch at the base and took a nap. Then in the afternoon, Li Polu drove around the base twice. Li Polu then walked back to the meeting room slowly.

After sitting in the conference room for a while, Huang Zu and others finally verified the formula given by Li Bolu.

At this time, everyone felt a little hungry.

Li Bolu hurriedly invited everyone to go to the cafeteria to eat.

In response, everyone who was in a good mood did not refuse.

On the way, Qian Qiang, who had worked with Li Polu before, asked, "By the way, Director Li. What did you want to say earlier?"

"Uh, it's okay. I was going to say earlier that there's a supercomputer in the base that you can use, so you don't have to do the calculations by hand."

Qian Qiang:..................

Everyone: Why do you suddenly not want to eat this meal?
