Into Unscientific Chapter 729

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

 In the conference room.

I heard what Li Jue said.

 Including the old expert who originally asked, everyone was startled.

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

 But less than two seconds later, there was a violent explosion:

 “What?! Neutron bomb?!”

The old expert who spoke out first couldn't help but stand up from his seat, put his hands on the table, and leaned forward:

“Director, what are you talking about? The neutron bomb will also explode this year?”

This old expert is called Wang Haoran. He went to Mao Xiong for training with Wang Ganchang in the early years and is currently responsible for the development of hydrogen spheres.

Li Jue nodded slightly:

 “That's right.”

　　While speaking, he inadvertently glanced at Xu Yun beside him.

Yes.

The true essence of this so-called "221 Base Completion Plan" is to "complement" the neutron bomb into the nuclear bomb's pre-detonation schedule.

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

 If it were not so

How is it possible for the organization to transfer all comrades engaged in nuclear power to the base this time?

After receiving Li Jue's reply, Wang Haoran murmured at the corner of his mouth a few times, as if he was hesitant to speak.

 It is true.

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

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

Furthermore, uranium-238 undergoes a fission reaction under the action of fast neutrons, which increases shock waves and light radiation as well as radioactive contamination of fission products, which is contrary to the design goals of neutron bombs.

 The detonation can only be effective when deuterium and tritium are injected into the neutron reflecting layer.

As a reflective layer, beryllium can reflect back the instantaneous neutrons, allowing them to fully function, thus greatly improving the utilization rate of neutrons.

At the same time, although beryllium is not a fissile 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 beryllium's "neutron breeding effect."

 This research direction does have a lot of overlap with nuclear power, to put it bluntly, the research and development of nuclear submarines.

  Nuclear submarine is a synthesis of various technologies, such as nuclear power plant, submarine shape, air support, navigation, sonar, etc. It is collectively called 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 breeding effect.

 At this time.

Due to the departure of the Mao Xiong expert, the 909 base responsible for the research and development of nuclear submarines has temporarily suspended its mission, leaving only a nuclear power research laboratory with more than 50 people.

So if it was for the development of neutron bombs, it would be normal for Peng Shilu and Zhao Renkai to appear on the completed list.

but

This TMD is a neutron bomb. How could it be possible to develop it so easily?

to be honest.

Wang Haoran subconsciously wanted to say something ridiculous, but before he spoke, he suddenly changed his mind. It shouldn't be possible for the organization to be so stupid, right?

So Wang Haoran swallowed what he originally wanted to say and replaced it with a more euphemistic expression:

“Director, is it too hasty to carry out research and development of neutron bombs simultaneously?”

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

 “That's right.”

Li Jue immediately affirmed Wang Haoran's statement:

“If we were to produce a standard neutron bomb, it would be impossible to do it this year with our current capabilities.”

“But what if our goal is to produce a miniature neutron bomb?”

Wang Haoran was suddenly startled:

 “Miniature neutron bomb?”

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

 “That's right, a miniature neutron bomb.”

“Comrade Haoran, we have already achieved standardization results in atomic bombs and hydrogen bombs, which means that the so-called 'actual force value' has been guaranteed.”

“In this case, we don't actually need to pursue the elasticity of the neutron bomb, but we just need to prove that we have mastered its production technology.”

“After all, the neutron bomb itself is used to deter certain people.”

Hearing this, Wang Haoran immediately fell into silence:

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

yes.

If all the Rabbits want to develop is a neutron bomb, then they will definitely not stop until they have a complete version.

  But the current situation is different.

 In addition to neutron bombs, the rabbits also have two physical weapons: atomic bombs and hydrogen bombs. There is no need to worry about the actual combat effects.

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

  The more important point is that

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

Atomic bombs and hydrogen bombs are a relatively widely spread concept today, and even ordinary people have some understanding of them.

Even if someone has never heard of it, the difficulty of explaining it is much lower - [It was the big firecracker that the Yankees threw at the neon, and everyone was familiar with it].

This kind of understanding exists not only in China, but also among many people abroad.

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

  But the neutron bomb is different.

The impact of neutron bombs on civilians is not as great as that of atomic bombs. Even these days, 90% of the people do not know what neutrons are.

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

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

This is a bit similar to Huawei in later generations. The only chip that can be produced in the short term is the Kirin 9000S. It is said that the performance of this thing is only slightly better than the Xiaolong 888, and is far behind Apple's A17 chip.

 But after China launches Kirin 9000S, which mobile phone manufacturer or even some countries will not be able to face a powerful enemy?

 This is the importance of core technology.

After mastering the core technology, it is only a matter of time before Kirin 9000S, Kirin 9100 or Kirin 9999 is launched.

 The same is true for neutron bombs. As long as the rabbits prove that they have mastered neutron bomb technology, it will be enough to keep the hostile forces awake in the middle of the night.

 At the same time, compared with the standard version of the Kirin 9100 (neutron bomb), the 9000S (micro neutron bomb) is much more difficult and time-consuming to produce.

If everything goes well.

 Perhaps it is really possible to complete the development of a micro neutron bomb by September 19?

Of course.

 The miniature neutron bomb and the miniaturization of the hydrogen bomb here are two concepts.

Hydrogen bomb miniaturization refers to achieving smaller size and weight with the same power, so that the delivery vehicle can carry more nuclear strike weapons at one time, which is much more difficult than the development of hydrogen bombs.

Just like if you want to feed your son to be a tall man with a height of 180cm and a weight of 180kg, it is not difficult, but it is much more difficult to make him weigh 180kg and be only 140cm tall.

 The micro neutron bomb is a standard reduction in size and power, which is equivalent to a proportional scaling.

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

“Director, if it is a micro neutron bomb, what is the specific plan?”

“Although the difficulty of micro neutron bombs is indeed lower, the theory still needs to be derived. Do we have any accumulation of results in this area?”

Li Jue smiled at him when he heard the words, and turned to look at Yu Da on the side:

“Hello, Comrade Yu Min, let me introduce you to this aspect.”

Yu Min quickly stood up from his seat:

 “Okay, director.”

Then Da Da picked up a stack of manuscripts about two centimeters thick in his hand, opened the first page, and said to Wang Haoran:

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

“To be honest, we encountered many problems during the development of the neutron bomb because there was no relevant information to refer to.”

“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 over at the right time to make many important suggestions. In the end, based on these suggestions, I came up with some immature results.”

 Speaking of which.

Duda couldn't help but scratched his hair shyly.

 Then he paused and continued:

“The first is the structural issue of the micro neutron bomb. Based on my calculation of the neutron transport equation, I optimized a structural plan that is different from the conventional missile body.”

“The outermost reflective layer of this miniature 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 Factory.”

“If my calculations are correct, the spherically symmetrical centripetal compression force can reach a pressure of 7777 kbar, and the neutron radiation dose can reach 8000 rads”

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

As the old saying goes, an expert will know if something is there as soon as he makes a move.

Although there has been no hands-on demonstration so far, Wang Haoran is already convinced by just hearing the structure and parameters reported by DaDa.

 Mentioned earlier.

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

From a neutron bomb process perspective, it can be roughly divided into seven steps:

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

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

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 focused towards the center of the sphere, allowing it to concentrate energy to excite the fusion material and obtain the necessary energy for fusion. Tens of millions of degrees of high temperature and high pressure.

 4. 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 reflective layer produces high temperature and high pressure focused toward the center of the sphere. The combination with the outward high temperature and high pressure produced by the atomic bomb explosion in the core is enough to trigger deuterium-tritium and deuterium-deuterium fusion reactions, thus 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 reflective layer and shield, and also produce a large number of neutrons, and the neutron bomb explodes smoothly.

Wang Haoran also participated in the design and derivation of neutron bomb parameters before joining the hydrogen ball project team. What Yu said is basically in line with his knowledge.

Hearing Da Da's introduction, Wang Haoran gradually made up a picture in his mind:

After the atomic bomb core detonates, X-rays are transmitted in the middle layer of lithium deuteride, triggering a relatively opaque radiation wave front in the invisible world, delaying the transfer of radiation energy like slowly moving wood on the water. .

Before the outermost reflective layer of plutonium-239 is blown away by radiation-induced ablation, the neutrons from the core of the atomic bomb in 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 that are focused toward the center of the sphere, allowing it to concentrate energy to excite fusion materials and obtain the tens of millions of degrees of high temperature and high pressure required for fusion.

"etc!"

After a while, Wang Haoran suddenly frowned:

“Comrade Bigger, how big is the miniature neutron bomb you designed?”

 Da Da gestured at a space almost the size of two watermelons in front of him:

“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 hydrogen spheres, Wang Haoran is very sensitive to data:

“Bigger than comrade, according to the size you said. Is there something wrong with the neutron source for detonating the atomic bomb?”

 Hear this.

Many experts at the scene also nodded subconsciously.

 We are all top theoretical scholars or engineers in the country, and we deal with various structures of atomic bombs almost every day.

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

If the neutron bomb is really so big, then the neutron source will not be enough - the energy range where high-order neutrons dominate is around 0.12 to 0.16, and the energy level of the single-energy strong neutron source is 14 MeV. If you want to achieve neutron radiation A dose of 8000 rad is almost impossible.

Could it be

Is it greater than a miscalculation?

 But in the lower right corner of Li Jue, where no one was paying attention, Xu Yun couldn't help but twitch the corner of his mouth a few times.

Perhaps many, many years from now, what happened today will become a joke in the history of rabbit armaments.

The bigger thing is hanging on the wall

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

“Yes, if beryllium or polonium neutron sources are used, their magnitude is obviously not enough.”

“But then consultant Xu Yun came up with an idea in a joking manner. After I returned to the dormitory, I spent a whole night doing calculations, and finally found that it was indeed feasible.”

Wang Haoran's face showed a little solemnity and interest:

 “Oh? I'd like to hear the details.”

Wang Haoran's solemnity lies in the fact that he really can't think of anything that can replace the traditional neutron source. This is a small challenge to his business ability. His interest is because the plan that can be presented at such a meeting must have been passed. With the organizational argument, the accuracy rate, at least on paper, should be very high.

Opposite him, Yu Da did not hesitate, but quickly gave the answer:

“This plan is to use mercury antimony oxide as the neutron source.”

Note:

I have always emphasized that you don't need to overthink things. The discussion plan I am talking about is discussing a logically feasible plan, which is two different things from practical implementation.
