What’s the material for the nuclear power plant?
Uranium.
But it’s true, as you can see: uranium 235 is too little, not much drained, 99.3% is uranium 238.
How?
In accordance with established practice, the rationale for nuclear power is to begin with.
First, we split “nuclear power” into two parts: warm baby parts and boil water.
The technology behind this is more sophisticated, not to mention.
We have to focus on the nuclear-related warm baby component.
Uranium enrichment
Uranium nuclear cleavages release energy, but when it involves energy change, it is mostly in the form of “heat” and “radiation”.
This is the source of the heat.
However, the “hot” light is not enough. It has to be whatever it takes.
The principle is also simple: control of uranium concentrations and the speed of fragmentation can control the speed of heat.
The first concept came out: uranium enrichment.
The chemically purified uranium, the chemically reaction electron, and the neutrons were inert, so the chemically purified uranium consisted of 99.3 per cent of uranium 238 and 0.7 per cent of uranium 235.
Because the chemical properties of the two are identical, if they are to be separated, they can only be separated by a small difference in the weight of the two, the most mature being the centrifuge.
Uranium is first turned into UF6 gas and then rotated in the cylinder.
The gas molecules of different weights are layered, heavy to the side, light to the middle, removed with a catheter, and continue in the next barrel, so that the concentration increases slowly.
How many times does that take?
We’ve been hacked.
The centrifuge is a highly controlled device for the big hooligans.
The abundance of 235 U for power generation is about 3% 5%, ship power 10% 20%, weapons class more than 90%, and natural uranium is only 0.7%.
They think hitting the reactor would cause a nuclear explosion.
Non-weapon-grade uranium, to better control the heat and the treatment of late-stage waste, adds other substances, such as our uranium molybdenum alloy, which is good, 10% uranium.
Countries that are able to build nuclear bombs on their own, the enrichment of uranium technology is certainly not under discussion.
Control bar
High concentration of uranium 235 is available, and the second concept follows: split speed.
The nuclear division of the atom is the top priority of the atom. Protons and neutrons are discussed, and electrons are side by side.
235U had 143 neutrons and 238 U had 146 neutrons, so they came up with different results: 235U split up fast and released fast; 238U split slowly and released slow.
It’s been a pleasant decision.
It’s known that 235 Us will split up spontaneously, with neutrons hitting it faster.
With one atomic nucleus, there are 2-3 neutrons, and the children and grandchildren are endless!
Perfect!
Question: Why is the nuclear nucleus spontaneous? It’s about Quantum Mechanicals.
There are several factors that affect the nucleus: concentration of 235 U, rate of neutrons, number of neutrons.
235U splits out of the neutron at a fast pace and often goes outside without hitting the other atoms.
In order to increase the probability of impact, either increase the concentration of 235 U (which becomes an atomic bomb, which cannot be played like this) or drop the neutron velocity.
Neutrons are very deep in water, so water is used to slow down the rate of neutrons.
This will allow the uranium to split slowly and heat slowly, but it will not be able to adjust the pace as it pleases.
Take it easy. There’s something else.
As shown in the figure, the blue uranium fuel rods on both sides of the right and the left are immersed in water.
Middle red rods are materials that absorb neutrons, such as boron, carbide, cadmium, etc.
At normal times, two fuel rods throw neutrons against each other, and the control rod is in the middle of the condulgence, so that the number of neutrons flying across the street can be controlled by controlling the rise or fall of the rod, thus regulating the pace of the atom nuclei, i.e. reactor heat.
These rods are like stabbing knives, hanging over the reactor.
When the wind blows, the rods go right to the end and the neutrons on both sides are stopped.
Fuel rods can only self-absorption on their own neutrons, with the lowest heat power, the so-called “crash” (which is not entirely unheating).
Can’t we just let 235U split up?
Quantum mechanics, no!
I can’t even find the theory!
In the absence of neutron bombardment, these atoms release energy at their own pace, a split, half-life.
Here comes the trouble.
‘Cause this guy’s got 365 days, 24 hours, every second of the heat.
Once the heat doesn’t come out, the temperature rises sharply. How hot can it be?
It took 120 seconds for the U.S.-Tripoli nuclear accident, from the cooling system to the complete destruction of the reactor.
Then it melts the core, causing the radioactive material to leak.
The most dangerous thing about a nuclear reactor is a cooling system failure, which is the core!
Mankind’s desire to take a chill in the fire is due to the great benefits of the atom.
At a time of heating, a warm baby can continue to heat for months to decades (a carrier usually for decades).
Chief’s been working overtime every day.
Because of the “overtime” problem, warm babies are divided into several groups.
Attention, students!
Reactor
Boiling water reactor:
The water is both a slower and a heater, and the uranium rods heat up in the water, heating the water to boil and fertilizing it to boost the wheel.
It’s kind of a panic, and the water’s radioactive, and it’s going to drive the wheel, so there’s always a gap in the turning, so there’s a leak, so there’s less fun.
But the well-known Fukushima and Chernobyl nuclear power plants are boiling water reactors because of their simple structure and low cost.
I’m scared, I never play with boiling water.
Pressure water pile:
By definition, press water not to boil, press it above 150 atmospheric pressures, and the boiling point of the water exceeds 300 degrees. This hot water heats the water outside through a circulatory pipe, so that the water outside is boiled and gasped and boosts the wheel.
The water thus exposed to the uranium rod is completely isolated from the outside world, is not easy to leak, is highly safe, and water pressure is a more dominant game.
My rabbit played nuclear power in a conservative manner, sentencing two people to nuclear bombs in the US-Susun nuclear bomb.
In recent years it has been estimated that it has grown, with more than a dozen pressurized water reactors under construction.
Can you see the difference between the two figures?
Light water reactor:
The slow water used for boiling and pressurizing water piles is called a light water stack using the most common water (commonly called light water).
It’s the most common pile. How cheap is the water?
Heavy water reactor:
Slowing water is called a heavy water pile if it uses gillated water, commonly known as heavy water.
This is a good one!
The nucleium is heavier than the hydrogen nucleus, so the neutron deceleration is better, the neutron absorption is less, the uranium concentration requirements are lower, and even natural uranium can be used as fuel.
The light water reactor, on the other hand, can only compensate for the loss of neutrons by increasing uranium concentrations, usually at 3 to 5 per cent.
The Qinshan III nuclear power plant is a heavy water dump, and Canadian technology, which is said to be the best in Canada, appears to be the largest project of cooperation between the two countries, except, of course, for the extradition of corrupt officials.
Hot pile:
It’s not a very good name, and the bricks call slow neutrons, not slow neutrons, the warm babies that slow down the neutrons, all called thermal neutron reactors, short: hot piles.
graphite gas freezer:
It’s called a “high-temperature cooler.”
I’m counting a dozen pressurized water piles, which, to be honest, aren’t very powerful, but with the graphite cooling piles, we’ve been playing the fourth generation of nuclear power!
There’s a big difference here and everybody’s staring.
The problem with the reactor is that the warm baby keeps getting hot.
The graphite gas cooler follows a very clever approach, plunging nuclear fuel into a graphite ball, using graphite as a slowizer (see, for example, now, the role of the slower) and then using very inert helium (or a heater).
What’s the beauty of this structure?
Let me describe the process:
The little coal ball in the middle is uranium fuel, 60 mm coal ball, with only about 0.2 mm uranium fuel in the middle;
In normal working hours, helium is blown to a pile of coal balls, so that helium is boiled to boil water and power;
When the coal ball is not hot, let it go from the bottom and then put a new coal ball on top and keep blowing;
In the event of a failure of the air-blowing system, the temperature exceeds normal, the system stops throwing new coal balls;
Let graphite and helium fight the heat inside. These guys are not afraid of heat, helium is light, 900 degrees, graphite, 1600 degrees.
Then the coal ball cools itself.
Amazing, my graphite ball!
The structure is very secure, and the University of Tsinghua has performed many times to shut down the cooling system directly, and the graphite cooling reactor has been automatically shut down without any outside interference.
It’s a very simple structure, and the simpler it is, the more stable it is, and it fits my rabbit style: Cheap!
In addition, the replacement of fuel rods by compressors is very cumbersome, so there is more material to add at a time and the disguise increases the risk factor.
High-temperature cold reactors are convenient, with tens of thousands of coal balls stored in their cores, which do not need to be too much and do not need to stop each time they are thrown in the middle, and are clearly safer and much more efficient than the pressurized piles.
If the graphite is so cool, why don’t you go up early?
Response:
A high-temperature, high-pressure helium back-routing requirement is particularly high.
The two are not made by anyone.
Three are less air-cooled than water, and have a less power density than the pressurized water reactor (the same size reactor, low power).
In fact, the British Empire was the first to play a high-temperature cooler 50 years ago, and unfortunately it was abandoned.
And now that they’re doing well, they’re cold, they’re not very technically connected, they’re all from nothing, so my rabbits are very happy.
It is said that it may now have gone to the front, and no, to the British Empire, where it is said that it is going to repair the nuclear power plant for the foreigners.
Says a bunch of “stacks.” Are you having fun? Don’t worry, there’s another pile!
Quick.
All the warm babies it says are slowing down the neutrons.
Next, a new person is introduced: the fast neutron reactor.
This is also the well-known fourth generation nuclear power, the world’s fourth-generation nuclear power system’s best-chosen pile, which has to start from scratch.
Although humanity has succeeded in reducing the atomic bomb that killed the Quartet to a “waterworker”, it is not long.
First, uranium 235 is too small to be drained, 99.3% is uranium 238.
Secondly, waste disposal is too cumbersome. And so people thought, “How to kill uranium 238.”
It’s a little hard to do it directly, but with a neutron, uranium 238 turns into plutonium.
So the hooligans strictly control the little hooligans play fast, and they build “production piles” on their own, the kind of reactor that doesn’t burn water and specializes in plutonium 239.
Of course, atom bombs are not easy to get away with, so let’s not think about some kind of house-to-house robbery, like plutonium 239 and uranium 235, which also creates energy through fission.
I got an idea!
Plutonium 239 as a reactor’s nuclear fuel, without a slow agent, is directly surrounded by uranium 238.
Plutonium 239 fission, producing neutrons that directly impact uranium 238, then uranium 238 becomes plutonium 239.
This process produces faster than consumption, with plutonium 239 burning more and more until uranium 238 is fully consumed.
So it’s called the Fast Neutron Generation Reactor, called the Fast Neutron Reactor.
By the way, the rumour is that plutonium is about 5 mg/kg, and those who kill 50kg will have to use 250 mg, not the rumor “5 grams to poison all of humanity.”
Fast reactors can burn almost all uranium fuel and make full use of the relatively large reserves of uranium 238.
However, there will be some waste in the previous period of fuel production, which, taken together, will account for 60 to 70 per cent of the utilization rate, which is much more than the original pile.
What the fuck, another one?
It’s not that simple!
You have to have hard wings!
Fast neutrons are used in fast piles, so they cannot be cooled with water (water is a slowant) and there is a strong internal reaction requiring a heat-guided coolant and fast-exporting of heat to boil water.
In other words, the first coolant does not slow down neutrons, the second heat is better, and this type of material is often metal.
So “high-temperature liquid metal cooling technology” is the core, or even the decisive, technology of fast stacks.
All right, let’s go to the second round and get another pile.
Number one: Sodium cold.
That’s right. Put nuclear fuel in metallic sodium!
The high-school chemistry students must have started to panic, not to mention that sodium piles are the most dominant fast pile, and China ‘ s first fast pile is also a sodium cold pile, which runs in 2010 and uses 260 tons of sodium metal, which is less in the peers.
Metallic sodium is much hotter than water, so power increases!
Even though sodium metal is good, it’s sodium metal!
The core works at temperatures above 500°C and hundreds of tons of high-temperature metallic sodium, which is considered to be a panic, which is very demanding for cooling systems, does not have absolute industrial power, or does not touch it.
For consequences, please refer to the Japanese collection.
Second: The cold-lead reactor.
It should be called the “lead-based fast stacks”, and the coolant uses aluminum alloy.
This is thanks to a team in the middle school, who also made the lithium-lead coolant from the fusion pile, who is good at heating with all kinds of lead-based materials!
Lead isn’t afraid of the air, it’s too cute for metallic sodium! The hard spot for the cooling of lead-based materials is very easily corrosive of casings and structural components, which dissolve the metal directly, as if they were boiling water with salt.
And think of that poor pump, which keeps pouring out the melted liquid lead, and then pulls out the water and then cools the cores…
At a time when the American Emperor, the furs, and the sharp edges of the pedals were corrosive, my rabbit suddenly launched the cold-lead reactor: nuclear treasure!
This motherfucker is selling nuclear energy as cabbage!
Don’t be afraid, it’s a small “nuclear treasure” with a few thousand to ten thousand kilowatts of power, driving thousands of vertical air conditioners, large containers and low power density.
However, there is still room for future upgrades, and lead aluminum cooling circuits are key and are now estimated to be the natural cycle of the coolant, and if the pump that drives the liquid lead is ready, the power will increase even beyond the sodium cooling reactor.
Lead is cold and fast, and now, although power is small, one is not enough for two or three, and it’s convenient to go off the island.
How? You didn’t read the ad?
“Do you want to cook tea eggs on Gobi Beach?” Want to go to the South China Sea to see the tide? Think about the offshore drilling platform? Let’s get rid of those diesel generators! Nuclear treasure, your choice! I’m sorry.
The learned students must have asked the former Soviets to cool the nuclear submarines.
It was a devil’s journey to fight the Emperor, and it didn’t solve the problem of lead corrosion.
Third: The air-cool fast pile.
Needless to say, helium is still helium, inert and high-temperature, but thermal power is small and can only be used as an alternative stack and the least promising.
Note the difference between the graphite cooler in front. It’s the hot pile. It’s the fast pile.
Other nuclear energy
After reading the principles of the hot and fast piles, everyone must have had a hard time, and the famous “nuclear power” would end up generating electricity by “burning water,” and I was crying when I knew the truth.
Is there any way not to do this? Yes, the Sebek effect is on the stage!
The Sebek effect, when two different conductors or semiconductors are attached together, produces a voltage, equivalent to a battery, if the temperature difference occurs.
And so everybody was happy, and using it, they made it:
Thermometer!
The thermometer! It’s too hot for you to make a thermometer!
There’s another name for this thing called Hot Episode.
The electron thermometers are all based on this principle, and the temperature can be measured at almost 30000 degrees.
The thermoelectric dolls have been played out in the field, and we’ve all had enough fun, so we’ve got another radioisotope heater, even though it’s called an electric machine.
The principle is simple: first, the thermoelectric dolls are made into a array, using unstoppable nuclear fuel, heating only the electrodes on one side, so that the temperature on both sides is poor, and then there is electricity.
Let’s take a look.
Conventional Nuclear Reactor Generator: Nuclear Energy – > Thermal Energy – > Thermal Energy – > Mechanical Energy – > Electrical Energy
Radioisotope heater: Nuclear – > Thermal – > Electrical
I got it, I got it!
Of course, it’s not enough.
The non-coolant nuclear fuel. How dare you make him too hot? Too hot for electrodes?
Only low-temperature stocks, typically plutonium 238, are available, with a maximum of hundreds of watts (power of several computers), but it can be used for decades, with light towers previously erected in the no-man’s-man’s-place by sun-poor deep-space satellites, the Curiosity Mars vehicle, furs, which are not in your car, mobile phone, anyway.
It’s expensive. It’s just a few kilos of battery, enough for the Emperor to pick a house.
Is there really no hope?
The U.S. City Labs Labs are known to have developed tritium batteries for 20 years.
Tritium is non-fissile, but decays, and its beta decay only releases electrons without lethal radiation and is safe for the human body.
The essence of electricity is the movement of electronics, so it can be used directly for power generation.
I don’t want to raise my power, 350 nA.
(Bearing, voltage multiplication is power. I’m not sure.
In the current scientific system, if you want to turn nuclear power into electricity, stop!
We wait for physicists to break down the basics.
The fusion power that humans are doing is burning up water, just in exchange for fusion.
Nuclear Tiger
To be honest, nuclear power accounts for dozens of percent of nuclear power in developed countries and less than 5 percent in China. Given the trend in China ‘ s nuclear power technology, nuclear power will be promoted in the future.
If you happen to have a nuclear power plant around your house, it’s interesting to know how it works.
Awareness of nuclear power hazards must be borne in mind: concentrations determine toxicity.
The human body is stronger than expected, and the Earth ‘ s people themselves are exposed daily to a variety of chemical pollution, bacteria, electromagnetic radiation, which is less toxic.
Let’s look at a few nuclear accident cases.
The nuclear people and the “nuclear” are very close, providing us with many rare cases of nuclear accidents, and we should all be grateful.
In 2011, the Fukushima nuclear accident in Japan was classified as the highest level 7 and the same level as Chernobyl.
Many know only the natural disaster caused by the earthquake, but do not know the human evil behind it.
The site was initially moved from the hill to the bottom because of the money problem.
Because of the money problem, the embankment is only 5 meters tall, and you know how much dead it is.
The construction of the Fukushima boiling water reactor was simple because of the money problem and a simple plant was added to the reactor.
It was 15 years since Fukushima was naked, and it was not until the Chernobyl accident of 1986 that he realized that he needed a safety shell.
Because of the money problem, only one layer of steel and concrete has been added to the shell, which is two different things, without a series of structures such as a spray system, a gas exchange system, etc.
The United States had a three-mile island nuclear accident because of the safety shells, and only 3 people had been exposed to slightly more than a six-month acceptable dose.
Fukushima has been naked for 40 years, and luck has finally run out of hardware problems and management problems!
After the earthquake, the control rod was inserted into the core automatically, the reactor heat was less than 10 per cent of the original level, the requirements for the cooling system were low, and everything seemed great.
An hour later, the 15-metre-high tsunami easily crossed the breaker.
Some of the mental retards placed diesel generators in the basements, filled in water, the off-site emergency power supply was also pushed down by the tsunami, four electrical safeguards were destroyed, and the cooling system relied only on backup batteries.
The batteries can hold up for eight hours, but it’s not that difficult at this point, after all.
The power plant immediately requested help from the Tokyo Power Company headquarters for the emergency deployment of diesel generators, the emergency of 100,000!
The head of the East Electric headquarters was absent as there was no preparation for mobile emergency generators.
In an emergency report, East Electric made a one-off call to the government: it’s all under control, but can we get a few generators?
The government didn’t take it too seriously.
Eight hours later, when the support team was walking the road, the Fukushima power plant was completely out of power.
The cooling system was completely shut down, and the next thing I know, I left by the script:
The temperature of the water in the core rises to boiling, and high temperature and high pressure vapour begins to break through some of the weaknesses in the core and leaks to the plant;
The cooling water level is decreasing as the steam leaks, and the core is finally exposed;
Fuel rods do not cool water parcels and melt themselves quickly with steam in the plant;
At the same time, high temperatures caused a hydrogen reaction in the thorium casing, which quickly reached the explosive limit.
At this point, it’s almost Mars.
Most surprisingly, much of the nuclear leak occurred because of a lack of knowledge of the core, but Fukushima staff knew everything about the three aircraft units.
In the absence of a leak, on-site engineers advised management to use the sea-water cooling reactor, but in so doing, hundreds of millions of dollars of aircraft were completely destroyed and East Electric was heartbroken and hesitant.
As a result, the field personnel watched the incident.
In all the links, this tragedy can be avoided only if one of us breaks the rules and decides to cool the sea.
When the emergency generators arrived, it took half a day to reconnect the power interface for lack of training, a few hours after the power had been cut, the reactor was already full of steam, pressure was too high to fill.
What should we do?
There’s only one depressure, which is the direct discharge of radioactive vapour into the atmosphere, two at a time, three at a time, until it can be injected into cooling water.
I don’t want to talk about artery, but it’s top-notch public relations.
For reasons of money, Fukushima does not have a hydrogen-free system, which is a nuclear power plant.
The callers quickly detected hydrogen in the plant, which scared the entire population.
Hydrogen’s patience was limited, but it exploded, and it blew up the plant.
That’s it. This big shithole is hopeless.
For reasons of money, the pit was always so open, and hundreds of tons of radioactive sewage were leaked into the ground and into the sea every day to cool the reactor.
It appears that the scavenging of the water from the scavengers, while shameful, is cost-effective.
Long-range diluting does not matter, so much attention is paid to the monitoring data of the Ministry of the Environment.
But it was tragic in the vicinity of Fukushima, where Otman had evolved, and Otman fish, Otman fruit, and so on, and some of the Otman used cars and Otman food had also been brought into the market.
The Fukushima nuclear incident was a full expression of Japan ‘ s social and cultural characteristics, and even a hidden sight of the pitfalls of class blocks, with interested friends able to dig deep.
Fukushima is a boiling water reactor, which itself is easily leaked, with 30 boiling water reactors and 24 pressurized water reactors in its soles.
I don’t know what the planner thought.
Remember the location of Fukushima, the tourist resort of the foot basin, the country of fruit, where Otmando hides.
The Japanese Manchu reactor represents another death.
We’ve got sodium, we’ve got plutonium.
As a result, 250 days later, a thermometer was broken due to design defects, and the liquid sodium leaked outside the system through the thermometer tube, causing a fire. I had to stop and fix it for 15 years.
In 2010, the Manga reactor was restarted, resulting in the fall of a stack of inter-relays (mechanics that capture fuel rods).
I think the chief had his hand cut off.
How much trouble is this motherfucker?
3.3 Tons of large iron, falling from 2 metres high, fell directly into the core of the reactor, and timid classmates must not imagine the scene, their hearts shiver, and then the rod is stuck, and the warm baby cannot stop.
Then take out the robot! Hundreds of tons of high-temperature metallic sodium. What’s wrong with the robot?
The control rods that may have been damaged could not be repaired and the reactor remained in high-power heat.
Can’t we wait for it to cool down?
Yes, the fast pile is characterized by plutonium 239, the more it burns, the tens of thousands of years.
Then how?
The key is the cooling system, which does not allow core temperatures to rise.
Is this a problem?
The failure rate at the Manchuria is already high, otherwise there would have been no more setbacks, and it is said that there was a cooling system that was still in operation during the previous period, and that almost all that had happened had to be filled.
After the accident, the pedestals kept it deep.
According to Reuters, the mechanics were later removed, but the extent of the damage to the stove was unknown.
There was a great deal of hope in the Manchuria, which was supposed to solve Japan’s energy problems for the next 1,000 years, and it took 1 trillion yen to build it for almost 30 years.
It’s a shame to throw it away. Try running.
At first, 20% power, nothing!
30%? Yes!
Forty percent?
One bite, 50% power! Oh, my God, this is so scary.
The chief then hanged himself, and then a bunch of people died.
The Japan Atomic Energy Research and Development Agency (JAXA) has investigated that the cumulative number of Wenshi’s overdue equipment has reached about 12,000, and it’s no wonder he hangs himself.
Why don’t you open it?
It takes about 30 billion yen for 30 years to get rid of the hysteria.
Then don’t open it.
If you don’t, 20 billion yen per year will be spent on maintenance, or the consequences will be worse than Fukushima!
Let’s get this straight: it’s gonna take 1 trillion billion years to build a time bomb, 30 billion years to break it down, or 20 billion dollars a year for maintenance.
As a friendly neighbour, let’s do something!
As a matter of fact, the entire nuclear power industry is poorly managed and accidents are frequent. If you want to lose weight, you can search East Hai Village’s Critical Nuclear Accident.
One thing to be said is that people’s mistakes are not for ridicule, but for self-serving!
Of course, the foreign moon must be more round than the Chinese. You’re too much money for a nuclear reactor. Shake it!
Finally, use Lord Yang!
It’s common knowledge that Lord Yang found inspiration when he was playing with bulletballs and managed to collide hydrogen atoms. And then I took the opportunity to sarcasticly put my head down like a dead-end nerd like me.

I don’t know.
Keep your eyes on the road.
