was silent, and he didn't know what Sakata Yin was thinking, he really didn't expect this, and he suddenly realized when he was awakened by Zhang Han, and there was no doubt about Chongxin's house in his heart, and more things sighed about the gap between himself and Zhang Han in thinking.

"Any questions?"

"Nope."

Hung up the phone Zhang Han looked at the time, it was almost 11 o'clock in the morning, today's weather is not bad, although the wind is blowing, but there is the sun, not particularly cold, there is a saying, if the wind does not blow in winter, it is good weather.

"Stop."

"Crunch!"

Chen Peng stepped on the brakes, and everyone leaned forward violently because of inertia, Ning Xiang's head hit the seat, covered and rubbed it, and the expression on his face seemed to be about to kill Zhang Han.

Youmeng just gently supported it with his hand, still looking so calm, and asked Zhang Handao, "What's wrong?" ”

Zhang Han looked at Chen Peng from the rearview mirror, "Go to Fukushima Daiichi Nuclear Power Plant!" ”

Chen Peng restarted the car, turned around and headed straight for Fukushima.

Ning Xiang was still not very happy, and asked, "Where are you going?" Not that there are no nuclear weapons labs? ”

Zhang Han asked Ning Xiangdao, "Give you a nuclear fuel rod, are you sure you can use it to make a mushroom bomb?" ”

Hearing Zhang Han's words, Ning Xiang's eyes immediately lit up, "You want to steal a nuclear fuel?" ”

Zhang Han pursed his lips, "Don't say it so ugly, it's good to borrow it." Then a very bright smile appeared on his face, "In a few days, I will return a piece of Benli to them!" ”

Ning Xiang's little face changed for a while, "Wait! I think about it. ”

"Don't worry, you think slowly."

I don't know how long it took, the sun had run from the east to the west, and the bumps along the way made everyone drowsy, Yumeng leaned his head against the car window with his eyelids drooping, but he didn't close his eyes, and Lele had already fallen asleep on Zhang Han's shoulder.

On the other side of the shoulder was Ning Xiang, Chen Peng glanced at the street sign, "It's here, you can get to the vicinity of the nuclear power plant within twenty minutes." ”

Zhang Han pushed Ning Xiang, "Hey, girl, haven't you slept enough, my shoulders are almost numb." ”

Ning Xiang opened her eyes from her sleep in a daze, and the first thing she said was, "I'm hungry." ”

Zhang Han shook his head with a smile and said to Chen Peng, "Let's go to the nuclear power plant later, find a place to eat first, I haven't eaten anything for a day." ”

Ning Xiang rubbed her eyes and looked at the surrounding scenery, "Where is this?" ”

"Fukushima!"

"Oh......"

When Ning Xiang sobered up, Zhang Han asked, "How is it?" ”

Ning Xiang still seemed to be confused, thought for a while and said, "If you want to trigger a fission explosion of uranium-235 or plutonium-239, which are necessary for nuclear reactions, the easiest way is to bombard the other with one of them. ”

Zhang Han scratched his messy head, "I know this, my brother also went to college, and the atomic nucleus will produce new nuclei under the bombardment of other particles, which is called a nuclear reaction." Radioactive elements such as uranium, thorium and radium, protons and neutrons in the nucleus can be continuously arranged from high energy to low energy, which is called nuclear reaction, and the excess energy released is called nuclear energy, and once this chain reaction is triggered, as long as there are enough raw materials, it will instantly produce very terrifying energy. ”

A little bit of incense, the promise yawned and continued,

"A nuclear reaction is a qualitative change by its very nature, but it is different from a chemical reaction in general. A chemical reaction is simply a rearrangement and combination of atoms or ions, while the nucleus remains unchanged. Therefore, in a chemical reaction, one atom cannot change into another. However, the nuclear reaction is the transfer of interstitial points in the nucleus, resulting in the transformation of one atom into another kind of atom, and the atom undergoes a qualitative change. The energetic effect of a nuclear reaction is much greater than that of a chemical reaction. The energy of a nuclear reaction is measured in megaelectron volts, while the energy of a chemical reaction is generally only a few electron volts. Can you imagine how much energy will be released?

Moreover, nuclear reactions cannot be achieved by ordinary chemical methods, but using many experimental techniques and theories of modern physics. First of all, it is necessary to use artificial methods to create mushroom bombs, such as helium mushroom bombs and hydrogen mushroom bombs, and use these "shells" to violently impact other atomic nuclei, thus causing nuclear reactions. All kinds of accelerators are designed to artificially produce charged high-energy particles and use them as nuclear "shells" to carry out nuclear reactions. When the neutron was discovered in 1932, not only did they have a correct understanding of the structure of the atomic nucleus, but also discovered that the neutron was a new type of nuclear "cannonball". Since neutrons are not charged, there is no electrical repulsion between them and the nucleus, so they are much more effective when used to produce nuclear reactions than other charged high-energy particles.

Nuclear reactions are generally divided into four categories: decay, particle bombardment, fission, and fusion. What you want to see is the enormous amount of energy released by particle bombardment, right? ”

Zhang Han's face bloomed with joy, "Yes, yes, yes, tell me if I can make it with fuel rods." ”

Ning Xiang said, "Theoretically, yes. ”

Hearing Ning Xiang's words, Zhang Han's heart instantly cooled half, and his smile froze, "What do you mean...... Theoretically! OK? ”

Ning Xiang rubbed her eyes again, "It's just that there are reaction conditions, but this condition is restricted, you don't want to think that if it can really explode, it won't explode sooner, and you can generate electricity there safely?" ”

This Zhang Han really didn't understand much, so he asked Ning Xiang with a smiling face, "How is it restricted?" Is there any way to reach out to the constraints? ”

Ning Xiang said, "The fuel rods stacked with 10x10x15 cubic centimeters of graphite blocks, there are round holes with a diameter of about 5 centimeters drilled on some of the graphite blocks, and metal uranium rods or uranium oxide rods weighing about 2 kilograms are placed in the round holes. ”

Zhang Han touched the handbar and groaned, "Hiss......"

"You don't have to think about it, uranium is a radioactive substance, as long as you come into contact with it, you will suffer from excessive radiation that the human body cannot bear, nuclear radiation is ionizing radiation, high-energy particles hit your body, its energy is enough to ionize molecules, in other words, it can destroy the molecular structure, not very appropriate metaphor is like a knife, you can't see it, but it wreaks havoc in your body, cutting off protein macromolecules, destroying your body cells, until it consumes energy or penetrates your body! In one day you will surely die. ”

Hearing Ning Xiang's words, everyone shuddered, and Yang Xu said, "Boss, let's forget it, that thing is too dangerous, it almost kills a thousand enemies and loses 10,000 yourself, this business can't be worth it." ”

Zhang Han shook his head, "Get the fuel rod first and then figure out a way." ”

At this time, the car stopped, and Zhang Han and a few people walked into a fast food restaurant, although French fries and cola were very unhealthy, and no one wanted to eat sushi anymore, Ning Yuan was not healthy.

After ordering the meal, several people came to a quiet corner, hurriedly ate and got into the car, Zhang Han lit a cigarette, leaned against the window to smoke and said to Chen Peng, "Go to the nuclear power plant!" ”

After another 15 minutes or so, the car came to the beach of Fukushima, and four white factories were still alive on the seashore in the distance, and a large amount of seawater used to cool the nuclear reactor was discharged from inside, and the crackling sound of the two high-voltage power towers was constantly making a clear sound.

The gate of the power station is closed, and the sign at the door says that people are forbidden, which means that they are prohibited from passing, and there is a warning sign for nuclear radiation, and no one handles the door, but you can guess it, even if no one handles, it is impossible for ordinary people to break in.

Chen Peng parked the car on the side of the road, "This is it?" ”

Zhang Han nodded and walked down, looking at the nuclear power plant from a distance, "Is nuclear energy an angel that brings inexhaustible energy to mankind, or a devil who brings death and disaster?" ”

Youmeng walked down and looked at the nuclear power plant, the blue sea and blue sky in the distance, there were a few seabirds flying at the sea level, there was a faint fishy smell in the air, listening to the sound of the waves crashing on the shore, the whole body and mind felt a great comfort.

"It's beautiful."

Ning Xiang still held a bottle of Coke in his hand, took a sip and said, "There is no difference between angels and devils in matter, some people just want it to become devils or angels, in other words, people are angels and devils." ”

"Hahahaha......"

Zhang Han smiled arrogantly, "Then let me be a devil!" ”

After speaking, he waved his hand behind him, "Ning Xiang, Dream, and Dog Eyes follow me in, and the others stay here, if there is a situation, don't care about us and leave quickly, it's best not to be discovered by anyone." ”

Liuzi nodded, "I'll park the car farther away, and I'll treat it as a tour." ”

Zhang Han walked forward with the three of them, not directly to the main entrance, but went around into the lush green belt to the side of the power station.

In the dry, lifeless grove, the footsteps of several people were blocked by a wall, more than four meters high, painted white.

The dog's eyes rushed up with an arrow, grabbed his head with both hands, jumped easily on the wall, and went in with almost no effort, Zhang Han raised his arm to signal and so on. After a few seconds, a whistle came out, and Yumeng walked over and jumped on the spot, and the corners of his clothes swayed, bringing a dizzying scent of incense, and then fell into it in an extremely elegant posture.

Ning Xiang applauded excitedly, "Sister Youmeng, you are so powerful." ”

Zhang Han stopped his waist and hugged Ning Xiang, Ning Xiang instantly felt that the sky was spinning, and he jolted violently a few times, and just wanted to scream, he found that he had come in.

patted his heart, "I'm scared to death Miss Ben." Then he glared at Zhang Han angrily, "Zhang Han, you bastard, can you make a ...... in advance?" Well...... Well!! ”

After coming in, the three of them hid behind an evergreen tree, and while Zhang Han covered his incense mouth, he watched vigilantly to listen to the movement outside.

I saw three guys wearing white full-body protective suits and wrapping themselves tightly from a distance.

Ning Xiang also signaled her mouth after seeing it, and Zhang Han let go of her.

"It's an inspection technician for a nuclear power plant's reactor."
