Chapter 729 Xu Yun: I Was Just Talking Casually, Who Knows if There Is a Cheat

". What if, in addition to the atomic bomb and hydrogen bomb, a neutron bomb is also expected to explode?"

In the conference room.

After hearing what Li Jue said.

Everyone, including the old expert who asked the question, was stunned.

There was a moment of silence in the huge conference room.

But less than two seconds later, a violent explosion sounded at the scene:

"What?! Neutron bomb?!"

The old expert who spoke first couldn't help but stand up from his seat, supporting his hands on the table, leaning forward:

"Director, what did you say? The neutron bomb will also explode this year?"

The old expert is called Wang Haoran. He went to the bear for training with Wang Ganchang a few years ago. He is currently responsible for the development of hydrogen balls.

Li Jue nodded gently:

"That's right."

While speaking, he also inadvertently glanced at Xu Yun next to him.

Yes.

The true essence of this so-called '221 Base Completion Plan' is to 'supplement' the neutron bomb into the pre-explosion schedule of the nuclear bomb.

On September 19th this year, the rabbits will not only activate the original god and hydrogen bomb, but also add neutron bombs to make a three-bomb explosion!

If not,

How could the organization transfer all the comrades who are engaged in nuclear power to the base this time?

"."

After receiving Li Jue's reply, Wang Haoran stammered a few times, looking like he was about to say something but stopped.

Indeed.

Neutron bombs use a mixture of deuterium and tritium, one of the concepts is the neutron proliferation effect.

Compared with ordinary hydrogen bombs, neutron bombs lack a layer of uranium-238 shell, because uranium-238 will slow down neutrons and reduce neutron energy.

Moreover, uranium-238 undergoes fission reaction under the action of fast neutrons, increasing shock waves and light radiation as well as radioactive contamination of fission products, which runs counter to the design goal of neutron bombs.

Only when deuterium and tritium are injected into the neutron reflection layer can the detonation be effective.

Beryllium, as a reflective layer, can reflect back the neutrons that occur instantly, so that it can fully play its role, thereby greatly improving the utilization rate of neutrons.

At the same time, although beryllium is not a fissionable material, it absorbs fewer neutrons than it emits. When a high-energy neutron hits the beryllium nucleus, more than one neutron will be produced. This is the "neutron proliferation effect" of beryllium.

This research direction and nuclear power, to put it bluntly, are indeed quite overlapping with the development of nuclear submarines.

Nuclear submarines are a combination of various technologies, such as nuclear power plants, submarine shapes, air support, navigation, sonar, etc., collectively known as the "seven golden flowers".

Among them, the nuclear power plant is directly linked to the nuclear reactor, and one of the difficulties is also the neutron proliferation effect.

At this time.

Due to the departure of the bear experts, the 909 base responsible for the development of nuclear submarines has temporarily stopped its mission, and only a nuclear power research room with more than 50 people is retained.

So if it is for the development of neutron bombs, it is normal for Peng Shilu and Zhao Renkai to appear in the supplementary list.

But

This is a neutron bomb, how can it be developed so easily?

To be honest.

Wang Haoran subconsciously wanted to say something ridiculous, but before he opened his mouth, he suddenly changed his mind. The organization should not be so stupid, right?

So Wang Haoran swallowed back what he wanted to say and changed it to a more euphemistic statement:

"Director, isn't it a bit too hasty to carry out neutron bomb research and development at the same time now?"

"After all, according to our original expectations, although the research and development of neutron bombs is also progressing, it will take at least two and a half years to produce live ammunition, right?"

"That's right."

Li Jue immediately affirmed Wang Haoran's statement:

"If we want to produce standard neutron bombs, then with our current capabilities, it is impossible to do it this year."

"But. What if our goal is to produce miniature neutron bombs?"

Wang Haoran was stunned:

"Miniature neutron bombs?"

Li Jue nodded again , like an intellectual, he picked up the chalk and walked to the blackboard. After thinking for a while, he found that he didn't know how to write, so he drew a circle:

"That's right, micro neutron bomb."

"Comrade Haoran, we have already achieved standardization results in atomic bombs and hydrogen bombs, that is, the so-called 'actual combat force value' has been guaranteed."

"In this case, we don't really need to pursue the actual elasticity of neutron bombs, but just prove that we have mastered its production technology."

"After all, neutron bombs themselves are used to deter certain people."

Hearing this, Wang Haoran immediately fell silent:

"."

He suddenly realized that he seemed to have fallen into a misunderstanding before.

Yes.

If the rabbits want to develop only one neutron bomb, then they must not stop until they have a complete body.

But the current situation is different.

In addition to neutron bombs, the rabbits also have two physical killing weapons, atomic bombs and hydrogen bombs, so there is no need to worry about the actual combat effect.

In this case, it is actually unnecessary to pursue neutron live ammunition in a short time.

The more important point is that

In fact, from the very beginning, the positioning of the neutron bomb was different from that of the atomic bomb and hydrogen bomb.

Atomic bombs and hydrogen bombs are now a widely spread concept, and even ordinary people know something about them.

Even if some people really haven't heard of it, it's much easier to explain it - [It's like the big firecrackers that the Americans threw at Neon, and everyone was cooked in one blast].

This kind of cognition exists not only in China, but also in many foreign people.

So as long as the atomic bomb and hydrogen bomb explode successfully, the public opinion and confidence at the civilian level can be established smoothly.

But the neutron bomb is different.

First of all, the influence of the neutron bomb at the civilian level is not as great as that of the atomic bomb. Even these days, 90% of the people don't know what a neutron is.

So when Xu Yun came up with the concept of the neutron bomb, its purpose was very clear - this thing is used to deter foreign countries and high-level hostile forces, and has little to do with the civilian class.

Therefore, compared to the complete neutron bomb, the rabbits actually only need to prove that they have mastered this technology.

This is a bit like Huawei in the future. The only chip that can be produced in the short term is Kirin 9000S. This thing is said to have a slightly better performance than Xiaolong 888, and it is a long way behind Apple's A17 chip.

But after China launched the Kirin 9000S, which mobile phone manufacturer or even some countries would not be as ready to face a great enemy?

This is the importance of core technology.

After mastering the core technology, whether it is Kirin 9000S, Kirin 9100 or Kirin 9999, it is just a matter of time.

The same is true for neutron bombs.

As long as the rabbits prove that they have mastered the neutron bomb technology, it will be enough to make those hostile forces anxious and unable to sleep in the middle of the night.

At the same time, compared with the standard version of Kirin 9100 (neutron bomb), the production difficulty and time of 9000S (micro neutron bomb) are much shorter.

If everything goes well.

Maybe it is really possible to complete the development of micro neutron bombs on September 19?

Of course.

The miniaturization of micro neutron bombs and hydrogen bombs here are two concepts.

The miniaturization of hydrogen bombs refers to achieving a smaller volume and weight under the same power, so that the carrier can carry more nuclear strike weapons at one time, which is much more difficult than the development of hydrogen bombs.

Just like you want to feed your son to be 180cm tall and 180kg in weight, it is not difficult, but it is much more difficult to make him only 140cm tall while weighing 180kg.

The miniature neutron bomb is a standard size reduction with reduced power, which is equivalent to geometric scaling.

"."

Wang Haoran then thought for a while and said to Li Jue:

"Director, if it is a miniature neutron bomb, what is the specific plan?"

"Although the miniature neutron bomb is indeed less difficult, the theory to be derived still needs to be derived. Do we have any results accumulated in this regard?"

Li Jue smiled at him and turned to look at Dayu on the side:

"Ahem, Comrade Yu Min, let you introduce this aspect."

Yu Min quickly stood up from his seat:

"Okay, Director."

Then Dayu picked up a stack of manuscripts about two centimeters thick and turned to the first page , said to Wang Haoran:

"Comrade Haoran, not long ago, after solving the theoretical problems of the hydrogen bomb, I put all my energy into the research and development of the neutron bomb."

"To be honest, since there was no relevant reference material, we encountered many problems in the research and development of the neutron bomb."

"For about two weeks, the research team did not produce any substantial results."

"But fortunately, Consultant Xu discovered the problems encountered by the research team in time and came to make many important suggestions in time. In the end, based on these suggestions, I came up with some immature results."

Speaking of this.

Dayu couldn't help scratching his hair shyly.

Then he paused and continued:

"First of all, there is the problem of the structure of the micro neutron bomb. Based on my calculation of the neutron transport equation, I optimized a structural solution that is different from the conventional bomb."

"The outermost reflection layer of this micro neutron bomb is plutonium-239, the second layer is an alloy of beryllium 6, copper and nickel, and the high-efficiency explosive is mainly CL20 currently being developed by the Second Branch."

"If my calculations are correct, the spherically symmetric centripetal compression hardness can reach a pressure of 7777 kilobars, and the neutron radiation dose can reach 8000 rads."

"In this way, 80% of the energy released by tritium-deuterium fusion is 14.1 MeV high-penetrating neutrons, and 20% of the energy is taken away by helium nuclei."

As the old saying goes, an expert will know whether it works or not once he makes a move.

Although there has been no hands-on demonstration at present, Wang Haoran has already believed it seven points in his heart just by hearing the structure and parameters reported by Da Yu.

Mentioned earlier.

A neutron bomb is actually a special type of hydrogen bomb, and the essence of a hydrogen bomb is actually a type of atomic bomb - it uses an atomic bomb as a trigger.

From the process point of view, the neutron bomb can be roughly divided into seven steps:

1. The atomic bomb explodes, releasing X-rays and neutrons.

2. These X-rays and neutrons heat the inside and reflective layer of the nuclear bomb.

3. The neutrons released by the atomic bomb explosion induce the outermost reflective layer plutonium-239 to begin violent chain nuclear fission, releasing X-rays to focus toward the center of the sphere, allowing it to concentrate energy to stimulate fusion materials and obtain the tens of millions of degrees of high temperature and high pressure required for fusion.

4. The fissioning plutonium-239 releases radiation, heat and a large number of neutrons.

5. Neutrons enter lithium deuteride and combine with lithium to form tritium.

6. The fission of the reflector layer produces high temperature and high pressure focused toward the center of the sphere, which, combined with the high temperature and high pressure generated outward by the atomic bomb explosion in the core, is sufficient to trigger deuterium-tritium and deuterium-deuterium fusion reactions, thereby generating more heat, radiation and neutrons.

7. The alpha particles released by the fusion reaction of the nuclear bomb explosion excite the beryllium metal in the reflector layer and the shield, and also produce a large number of neutrons, and the neutron bomb explodes smoothly.

Before joining the hydrogen ball project team, Wang Haoran also participated in the design and derivation of neutron bomb parameters, and what Dayu said basically conforms to his cognition.

After hearing Dayu's introduction, Wang Haoran gradually made up a picture in his mind:

After the atomic bomb core exploded, X-rays were transmitted in the middle layer of lithium deuteride, triggering a relatively opaque radiation wavefront in the invisible world, delaying the transmission of radiation energy like a piece of wood moving slowly on the water.

Before the outermost reflective layer of plutonium-239 is blown away by ablation caused by radiation, the neutrons in the core of the atomic bomb at the detonation center will catch up with the X-rays and shoot into the outermost reflective layer of plutonium-239.

Plutonium-239 begins to undergo violent chain nuclear fission, releasing X-rays to focus on the center of the ball, allowing it to concentrate energy to stimulate fusion materials and obtain the tens of millions of degrees of high temperature and high pressure required for fusion.

"Wait!"

After a while, Wang Haoran suddenly frowned:

"Comrade Dayu, how big is the micro neutron bomb you designed?"

Dayu gestured in front of him with a space about the size of two watermelons:

"It's about the same as a winter melon, with a mass of about 30 kilograms, 90% of which is the weight of high explosives and some metal structures."

"That's not right."

As the person in charge of the development of the hydrogen ball, Wang Haoran is very sensitive to data:

"Comrade Dayu, according to the size you said, is there something wrong with the neutron source for detonating the atomic bomb?"

Hearing this,

Many experts at the scene also nodded subconsciously.

They are all top domestic theoretical scholars or engineers, and they deal with various structures of atomic bombs almost every day.

So at this time, in addition to Wang Haoran, many scholars at the scene realized that something was wrong:

If the neutron bomb is really that big, then the neutron source is not enough - the energy range where high-order neutrons are dominant is around 0.12 to 0.16, and the energy level of the monoenergetic strong neutron source is 14MeV. It is almost impossible to achieve a neutron radiation dose of 8000 rad.

Could it be that

it is greater than the calculation is wrong?

And in the lower right corner of Li Jue, who was not noticed by anyone, Xu Yun couldn't help but twitching his mouth a few times.

Perhaps many, many years later, this scene that happened today will become a joke in the history of rabbit armaments.

Da Yu is really a wallflower

Then, under the gaze of everyone, Da Yu took a deep breath:

"That's right, if beryllium or polonium neutron sources are used, then their magnitude is obviously not enough."

"But later, consultant Xu Yun came up with an idea in a joking manner. After returning to the dormitory, I spent a night doing a calculation and finally found that it is indeed feasible."

Wang Haoran's face showed some solemnity and interest:

"Oh? I would like to hear more about it."

Wang Haoran's solemnity lies in that he really can't think of anything that can replace the traditional neutron source. This is a small challenge to his business ability. The interest is because the plan that Da Yu can bring out at such a meeting must have been demonstrated by the organization, and the accuracy rate. At least the accuracy rate on paper should be very high.

Opposite him, Da Yu didn't keep it a secret, but quickly gave the answer:

"This plan is to use mercury antimony oxide as a neutron source."

Note:

I have always emphasized that there is no need to overthink. What I mean by discussing the plan is to discuss a relatively feasible plan in logic, which is different from actual operation.
