Chapter 292

——【Damn! Damn! Natural nuclear reactor? This works too? Today, my three views were subverted again. Scientists have studied for most of their lives, and the answer is right in front of them. How can those countries that can't research nuclear weapons feel?】

——【Compared with nature, human beings are too small. Things that took a lifetime to research were created casually. It is said that every star is a natural nuclear reactor. It's just that one is fusion and the other is fission, but they are all nuclear reactions. It seems that the formation conditions are more demanding.】

——【All signs indicate that Blue Star has possessed at least one civilization before, and the peak of development is likely to surpass our current one. For the universe, the time from the Stone Age to the present is just a flick of a finger. The evolution of human civilization is like one stubble after another of ant nests on the wilderness.】

——【What kind of bullshit natural nuclear reactor, this is the cave mansion that the old man practiced in, and it was dug by this group of people. The heaven and earth energy contained in it is something that you mortals can understand?】

As soon as this was said, Captain Wang's eyes were about to pop out.

Others were no better.

They have heard the term nuclear reactor on TV or mobile phones, and naturally know what this thing is for.

For example, nuclear power plant leakage, nuclear reactor out of control in movies... they have all heard a little bit.

But now Fang Yang actually told them that the yellow rock wall in front of them is a natural nuclear reactor.

This made them really unbelievable.

Such a terrifying thing is right in front of them, and it doesn't look very exaggerated.

It's like someone told them there is a nuclear bomb in front of them, which will explode at any time, but this nuclear bomb looks like cotton candy, harmless to humans and animals.

Facing this situation, everyone panicked and was at a loss.

Captain Wang frowned: "I know very little about this, but it's the first time I've heard of a natural nuclear reactor. Nuclear bombs were invented in the 19th century, right!"

Fang Yang nodded and took a deep breath: "It is very demanding to form a natural nuclear reactor! I estimate that this is likely the first natural nuclear reactor discovered in the world so far!"

Hiss~~~

Even Captain Wang couldn't help but gasp when he heard this, let alone the people behind.

"Uranium mines are many, but to have a nuclear reactor, first of all, its main element must be uranium 235, and the concentration of ore must exceed 3%. You know, uranium 235 is very rare, and it is even rarer for the concentration to exceed 3%!"

"Secondly, to undergo fission, it needs a neutron moderator, and water can do this step completely. You know, most uranium mines are in stones. If you want uranium mines to encounter water, they must be exposed to the surface. This is the second difficult place."

"First, the villagers broke the groundwater layer of the uranium mine, leading to water seepage in the mine. A large amount of water from the underground dark river washed the uranium mine in the cave, coupled with the existence of oxygen, it can react with the uranium in the ore to form uranium oxide and dissolve in water, which can help uranium undergo stable fission reaction."

"With these natural conditions, they began to undergo nuclear reaction. When a neutron hits uranium 235, it will briefly form uranium 236. Uranium 236 splits rapidly to release energy and produces another three neutrons. These three neutrons are moderated in water, which will significantly increase the reaction cross-section with uranium 235."

"In other words, it turns a grain of sand into a handful of sand and sprinkles it over. Only one neutron is needed to continue to hit uranium 235, and it will constantly split, producing a lot of energy."

"Now you should understand why the power of nuclear bombs is so great. It is different from traditional explosives. One kilogram of uranium 235 can produce an incredible explosion effect through constant splitting!"

Everyone was shocked after listening!

It was more dangerous than they expected. The terrifying degree of the yellow rock in front of them was far beyond imagination.

Captain Wang asked nervously: "Is it that as long as there is no water, it will not continue to split? Why don't we hurry up and block this cave entrance, don't let the water flow in!"

Fang Yang shook his head: "No, don't you know if you have watched movies? Generally, there are metal rods in nuclear reactors! Its name is control rod, it is equivalent to the accelerator of a car, but it is not used to release neutrons, but to absorb neutrons!"

"For example, nuclear submarines, if you want it to drive faster, pull out the control rod to accelerate the nuclear fission reaction. Conversely, if you want it to be slower, insert the control rod to absorb neutrons and slow down the fission speed!"

"Water can act as a neutron moderator to help split, and it can also act as a cooling effect. If all the water is pumped away, if the splitting here continues, the temperature will get higher and higher, and eventually a big explosion will occur."

"With the concentration of uranium mines here, if an explosion occurs, at the very least, our entire Xihai City will be gone! Most nearby cities will suffer!"

"The most important thing is whether there is only this one nuclear reactor in this uranium mine is still an unknown. If the quantity is large enough, to be honest, if it really explodes, our entire Blue Star will be gone!"

"You know, the Little Boy atomic bomb carried 65 kilograms of uranium 235 back then, and only one kilogram produced fission to cause such a big explosion. Look at us here, imagine how exaggerated what I said is!"

【Popularity】 +1+1+1+1....

——【My god! This isn't a joke, right? If this thing really explodes, will it penetrate Blue Star? Is this thing radioactive? They are standing next to it, will something happen! But it seems there is nowhere to run...】

——【Don't worry, uranium radiation cannot penetrate the skin, so it's safe. Only by adding other elements to cause nuclear explosion will there be radiation. I have seen humans use the particle stream released by nuclear fusion to directly kill tens of thousands of Zerg at an astronomical distance!】

——【Damn~ you can even describe drying quilts so high-end, I'm convinced. For humans, the conditions for nuclear fusion are very demanding, but for the universe, this is really not worth mentioning. There are too many unbelievable things in the vast universe.】

——【Nuclear fusion releases energy until it finally becomes iron. From iron, if continuous fusion is required, more energy is needed to maintain it, while heavy metal fission releases energy until it finally becomes iron. Iron is the most stable element of energy. The ultimate destination of the universe is to become iron, so the word iron son shows that the relationship is particularly stable. I have to say that the Chinese characters are really profound!】

——【Since ancient times, comments have produced talents, a "damn" goes all over the world, the people above are all great gods, little brother worships!】

Now everyone is completely panicked!

Fang Yang's words are like a nuclear bomb, challenging their endurance again and again.

Every time they thought they were exaggerated enough, they found that they were too naive.

One kilogram of fission in the Hiroshima atomic bomb can destroy a city. How much is here?

The entire uranium mine is calculated in tons!

The storage of concentrated uranium 235 inside is naturally amazing.

Coupled with the circulation of the underground dark river recently, a large amount of water resources appeared here.

It is hard to guarantee that no other places have nuclear reactions.

Thinking about it this way, it's too terrifying.

This one is enough to destroy Xihai City, if there are really many, then... dare not think!

Captain Wang took a deep breath, his head buzzing, and his brain was just in a blank state.

Just now they were leaning against this terrifying nuclear reactor.

This one thing is enough for them to brag about for a lifetime!

But if there is another chance, they wouldn't dare to lean against it even if they were beaten to death. This is simply looking for death.

Even if they die, they might implicate countless people to perish together.

163. A treasure more precious than gold! (Please subscribe!)

After Fang Yang's explanation, everyone understood why there were no funerary objects inside.

But its archaeological research value is definitely no less than those cultural relics.

Because archaeology is mainly to understand history through cultural relics, and in essence, it is tracing back to things that happened in the past.

However, just as they were about to leave.

Suddenly!

Boom~~~

Everyone heard a series of rumbling sounds.

And this sound was obviously coming from the top of the head.

Fang Yang shone the light on the cave roof and vaguely saw a lot of water flowing down.

Just at this moment, he saw the cave roof seem to loosen.

Is it an illusion?

Fang Yang suddenly thought of what happened before and shouted: "Everyone run, the cave roof is about to collapse!"

After saying this, he ran forward without hesitation.

Everyone was stunned for a second and then followed closely, even the dumbfounded villagers couldn't care about anything else and ran wildly behind.

Sure enough!

Before running for ten seconds, they heard a rumbling sound behind them.

At the same time, they felt some shaking on the ground.

When they shone the searchlight back, they found that the place they were standing just now had fallen a lot of stones and mud.

At this time, it was still falling down constantly. If it weren't for Fang Yang's early reminder, they might have been buried alive this time.

Transit group (3) 717 (2) 911 (9)

What's more coincidental is that a rustling sound came from the sinkhole direction.

Fang Yang only felt his scalp numb, and before he could shout, he saw a large flood rushing over like a high-speed train!.

162. Damn! Discovered a natural nuclear reactor! (Please subscribe!)

The flood rushed over very fast, and there was no time to run, and nowhere to run.

Everyone grabbed the stalactites at the first time to resist the flood.

But when the flood came to the front, they found that they couldn't grab it at all, and some were even broken by the water flow.

Water and fire are ruthless. Under such a huge water flow, no one can stop, and everyone is washed down with the water flow.

Fortunately, the cave is relatively spacious, so they won't hit the wall.

Everyone only had one head left outside, trying to keep their balance so as not to lose their weight.

The light shone on the front to avoid hitting the wall. Even the cameraman held the camera up until this time.

I don't know how long they were pushed by the water flow, suddenly they saw a rectangular thing stuck between two stalactites.

Fang Yang shouted: "Everyone hurry up and hold the coffin!"
