Development of productivity started in 1981

Chapter 53 Base Construction (asking for monthly tickets, recommendation tickets)

On Sunday morning, Wang Jiankun interviewed the warehouse manager introduced by Du Weiqiao and also went to his home to take a look. Wang Jiankun decided to try him out for two months. If he was suitable, he would continue to employ him. If not, he would find another person.

After a while, I will install a monitoring system and a defense system here, and then build a mobile base station on the mountain behind, so that I can carry out remote monitoring.

After the base in Wuyuan is built, we will build an underground base here. There are abundant metal resources here, transportation is more convenient, and there are many foreign populations. Wang Jiankun will not be conspicuous here.

After the interview, Wang Jiankun rushed back to Wuyuan County.

Fang Guihua and his friends were practicing typing on the computer. When they saw him coming, they handed him three test papers.

"Jiankun, this is our test paper. I didn't even turn the pages when I was doing it, and I did it at the required speed."

"That's good. I'll take a look at it tonight and give you the materials and test papers for next week tomorrow. What are you having for lunch?"

"We bought a chicken and some potatoes and stewed them together. Stews are more delicious in this season, as stir-fried dishes get cold easily."

"Okay, let them continue to practice typing. I'll give you the motorcycle to practice on. You can also practice riding a bicycle, right?"

"Okay, now that I can ride a bike, I can practice riding a motorcycle."

Wang Jiankun watched Fang Guihua practice while watching the pot. After half an hour, he used chopsticks to test the chicken and found that it was very rotten, so he asked several students to stop and eat.

They all brought lunch boxes. They each scooped out most of the rice from the box, then scooped out a small half of potatoes and chicken nuggets from the box. They pulled the stools into the yard, sat around and started eating.

Although the lower part of the rice cooked in a large iron pot with firewood is a little yellowish-brown, it has a very special burnt aroma. When it is soaked in the chicken broth, the taste is absolutely amazing.

Six people were sitting under the warm autumn sun while eating with sweat on their heads. They added a little rapeseed oil to the rice crust at the bottom of the pot and fried it over the fire. It was delicious.

Several people shared the brown rice crusts equally and ate them with a crunch at the door.

After finishing the meal, everyone washed their hands and cleaned their lunch boxes. After discussing, they decided to choose between the iron pot and the ceramic pot for stewing chicken by flipping their palms.

Several people stand in a circle, put one palm behind their back, then shout "start" at the same time and bring their palms in front of them. When there are only two palms on the front or back, those two people are the ones who go to wash.

If there weren't exactly two identical ones, they would keep repeating the process. It took six turns before they succeeded. Because Wang Jiankun was cheating, the moment several people turned over, Wang Jiankun knew whether they were going to put up the front or the back side. So in order not to be chosen, he had to resort to this last resort.

After the selected Lang Junjian and Hu Chunming washed and put away the iron pots and clay pots, Wang Jiankun asked them and three other people to stay here to play computer games and help him watch the door, as he was going to Yuyu Garden to build an underground base.

Considering that a large amount of things will be transported in and out in the future, there cannot be only an entrance and exit under the house.

Behind the mountain is a small path more than 2 meters wide, which is a shortcut connecting the county town opened by several production teams on the edge of the county town.

Wang Jiankun was planning to open an entrance and exit behind the mountain. Since he only hurriedly observed the road conditions and the shape of the mountain last time and did not check them carefully, he had to investigate again.

I rode a motorcycle for about two kilometers to the back of the mountain. After looking back and forth twice, I found a valley that seemed to be closest to the vertical shaft.

I chose a place in the valley that was easy to walk on, climbed up the mountain and looked at the terrain. I found that the valley was not far from the house, about 80 meters in a straight line.

He then used his super powers to check the interior of the mountain and discovered that it was filled with rock, covered with a layer of red-yellow soil more than 3 meters thick. This is the representative red soil of Jiangxi Province, rich in the three elements of iron, aluminum and silicon.

So it was decided to set up the exit in this valley, and try to keep the valley's topography unchanged when building the passage.

Wang Jiankun used his superpowers to dig a straight passage leading to the internal vertical shaft. The straight passage was not planned to be very large at the beginning, just 2 meters high and 1.5 meters wide, so that materials could be transported by a small cart.

After the internal freight elevator is installed, it will be expanded into a passage that can accommodate cars.

After a week of extreme use of the superpowers, the volume that can be moved is now 150 cubic meters per day.

So after finding the right location, Wang Jiankun spent about 40 minutes to dig a 50-meter passage leading to the internal vertical shaft.

The side walls of the passage are made of aluminum alloy synthesized from aluminum and magnesium elements, the ground is also hardened into cement, and the top is made of super-powered iron mesh to fix the gravel.

At the entrance of the passage, a moving door that simulates a mountain environment was made using superpowers. There are hidden slides and wheels underneath, which can be easily pushed.

Wang Jiankun walked over and pushed the door open, revealing a dark passage.

He waited for several minutes to allow outside air to enter, then used pine resin from the mountain to make a small torch, lit it with a lighter, and walked into the passage holding the torch.

It is necessary to use torches for lighting at this time, because the ventilation system has not been installed yet and the air circulation is very slow. It would be dangerous if you fall down inside due to lack of oxygen. Having torches to warn is also a layer of protection.

Wang Jiankun was also a skilled and courageous man, and he moved forward in the dark passage relying on the light of a small torch.

He didn't dare walk too fast, and it took him about 3 minutes to reach the end.

Standing on the edge of the shaft, the flickering light of the torch could barely illuminate the shaft wall 3 meters away.

Looking at the dark underground entrance, Wang Jiankun took two steps back.

At this time, the vertical shaft is 50 meters deep. If you fall down, you will be smashed to pieces.

Wang Jiankun held a torch in the darkness, as if he was standing in the dark universe holding a bright star, guiding the direction of human progress.

Wang Jiankun was a little intoxicated as he imagined the base being built, brightly lit, with robotic arms and self-driving cars busy at work.

After a long while, he felt the flame of the torch was slowly decreasing and his breathing was a little difficult. This was a warning that the oxygen content was below a certain level. Wang Jiankun turned around holding the torch and quickly walked back out of the passage.

Today's superpowers have been used up and nothing more can be done. After the copper and zinc are transported back from Dexing in a few days, Wang Jiankun will start building the elevators, wires and cables for the vertical shaft.

Several tons of iron have been collected and placed on the inner walls of the passage and underground. Together with zinc, it can be used to make the car structure. Galvanized iron components can also prevent rust.

Copper is used to make motors and cables. The electricity source is temporarily connected to the rented house, which can be used to light some lighting lamps and drive elevators.

I had already discussed this with the homeowner some time ago, and then asked people from the water and electricity bureau to install a separate electric meter, and the wires in the house were also replaced with thicker ones.

For the subsequent laboratories and small-scale production electricity needs, a diesel engine will be manufactured first. As for some high-energy experiments to be carried out after the first floor is built, Wang Jiankun plans to make a small nuclear reactor to provide power.

Currently, Zhizi is helping with the design, and Wang Jiankun is also collecting information and learning about nuclear energy.

After exiting the dark passage, Wang Jiankun pushed the exit door, and after closing, the door merged with the entire mountain.

The color is the same as the soil layer next to it, and you can't see it unless you look closely.

Even if someone came in and found it, they couldn't open it. It would automatically lock once it was closed. Wang Jiankun had to use his superpowers to unlock it from the inside to open the door.

After looking around the valley, I thought I should find a way to rent this place and build a warehouse to cover it up.

However, it may not be possible to ask for land leasing now. We have to wait until County Mayor Wu successfully promotes the suitcase project.

He rode a motorcycle to send a telegram to his uncle in Hong Kong, asking him to call Peter there and ask him to help find some journal materials related to microscopic particles and nuclear physics in Hong Kong or the United States, saying that he was planning to do some theoretical research.

Then I helped buy 2 tons of compressed helium from the United States, saying that it was for inflating balloons when they were sold. There is plenty of helium in the United States and it is cheap.

Wang Jiankun studied the periodic table in the early stage and decided to choose helium as the cooling medium when looking for a coolant.

Today's large nuclear power plants all use water as a cooling medium, and require the construction of very large cooling towers.

Moreover, the water in the first loop will carry a large amount of radiation, and the water in the second loop will also have trace amounts of radiation, so the miniature nuclear reactor certainly cannot use water.

Helium is a substance that cannot be excited by radiation. Since it is an inert gas and does not react chemically with other elements, it is an ideal cooling medium for micro nuclear reactors.

As for the source of fissionable materials, Wang Jiankun plans to find an opportunity to go to the beach and use his super powers to collect uranium after the preliminary design of the micro-reactor is successful.

High school textbooks introduce the properties of uranium, its reserves around the world, etc. Uranium exists in seawater, but the content per ton is extremely small.

Why is there no country in the world that extracts uranium from seawater? All major countries are close to the sea, so it is very cheap to extract uranium from seawater.

That's because obtaining uranium by conventionally filtering seawater is extremely uneconomical. Not only does it consume a lot of electricity, but the filter membranes consumed in the process are also very expensive and difficult to manufacture. The economic benefits are far less than extracting it from uranium ore.

As for studying cutting-edge research on microscopic particles, it is also to prepare for increasing the abundance of uranium 235.

Uranium has two isotopes, uranium 235 and uranium 238, and only uranium 235 can fission to provide energy. However, the abundance of uranium 235 in nature is very low, accounting for only 0.7%. If the collected uranium is used directly as fission material without refining, the efficiency of power generation is very low.

The conventional purification method is to use a multi-stage gas centrifuge to separate and purify uranium 235, which has three fewer neutrons than uranium 238 and a slight difference in mass between the two.

This process needs to be repeated several times, which consumes a lot of electricity. The centrifuge and filter membrane are also consumables that are very difficult to manufacture.

Currently, there are only four of the five permanent members of the United Nations Security Council in the world that have the ability to purify uranium, which shows how difficult it is to purify it using conventional methods.

If Wang Jiankun wants to purify it, he can only use his superpowers.

This requires a greater understanding of microscopic particles in order to distinguish between the two uranium atoms that currently appear to be identical.

According to Zhizi's speculation, Wang Jiankun's ability to control and observe microscopic matter improved with his cognition.

At present, he only has a better understanding of the atomic level, so he can only observe the atomic structure of matter. The internal atomic nucleus and electrons are more advanced knowledge.

Although there are some introductions to structures smaller than atoms in high school physics and library books, they are all very simple and seem like popular science descriptions.

These simple descriptions were not enough for Wang Jiankun to understand the properties of protons, neutrons and electrons in the internal structure of the atomic nucleus.

So Wang Jiankun hoped that Peter could help him find some journal materials on the research of microscopic particles.

Currently, Europe and the United States are conducting the most in-depth research on microscopic particles. They have built particle accelerators and begun to study matter that is smaller than protons, neutrons and electrons, that is, elementary particles.

There is a magazine that briefly introduces the current research status of elementary particles.

The collider accelerates two beams of protons to a few percent of the speed of light and then collides them. The protons that successfully collide will break into many fragments.

By capturing the trajectories of fragments through scientific instruments, the properties of these fragments can be studied and inferred. Scientists call some of the fragments that appear frequently and have the same trajectory elementary particles.

After sending the telegram, Wang Jiankun returned to the scrap recycling station. When his junior high school classmates saw him come back, they said goodbye and left for school.

After the others walked away, Wang Jiankun used a motorcycle to carry several times the metal ingots and silicon ingots that had been purified in the early stage to Yuyu Garden.

A passage connecting to the vertical shaft of the underground base has been dug here. This passage is mainly used to facilitate Wang Jiankun's entry and exit. It is only 1 meter wide and 2 meters high.

The passage is only about 30 meters long, and the other end is connected to the passage leading to the valley behind the mountain, which is separated by a door by Wang Jiankun.

Stack the wooden boxes on the side of the passage first, and then transport them underground after the elevator is built.

After moving the goods three or four times, Wang Jiankun felt that the efficiency was too low. Tomorrow he would use his superpowers to make a two-wheeled cart with wheels that can be tied to the back of a motorcycle, so that the moving process would be much faster.

During the evening self-study period, Wang Jiankun went to the classroom to study. He took out a piece of white paper and took notes while thinking about the NS problem. He wrote down the ideas that suddenly came to his mind, and then asked Zhizi to verify them.

We spent two classes and came up with 7 or 8 ideas to model and verify the Zhizi, but none of them worked.

In the third class, he changed his mind and continued to study miniature nuclear power plants.

Currently, large nuclear power plants use uranium 3.5 with an enrichment level of about 235%, which is made into small cylinders about two centimeters high and then installed in alloy round tubes.

These alloy tubes can withstand high temperatures ranging from 1800 to over 3 degrees and will not melt easily.

Many such tubes are put together and immersed in pure water, and then cadmium metal rods are used as neutron absorbers and beryllium or polonium as neutron sources to ignite the nuclear reactor.

After excitation, the neutron source can be turned off. At this time, the power of the nuclear reactor is controlled by controlling the insertion degree of the cadmium rods. The more cadmium rods are inserted, the slower the chain reaction of the uranium rods, the less heat is generated, and the lower the power generation capacity is.

The fewer cadmium rods are inserted, the faster the chain reaction will be, the more heat will be generated, and the higher the power generation capacity will be.

Wang Jiankun also uses the same control principle, but the materials used are different.

I learned from high school textbooks that graphite is also a very good neutron absorption and deceleration material. Graphite is also resistant to high temperatures and can be used as a structural material after compaction.

Bored Wang Jiankun used a pencil to draw the reactor core designed with the help of Sophon.

The entire core is a hexagonal prism with a hexagonal cross-section, a side length of 6 meter and a height of 6 meters.

It is composed of hexagonal graphite columns.

Each graphite column cross section has 6 holes with a diameter of 2 cm and 18 holes with a diameter of 1 cm.

The large channel is used to fill the fission material, and the small channel is used to conduct helium.

The fissile material is designed to be in the shape of small balls, with a ceramic shell on the outside and uranium material with an enrichment of 20% inside.

A single small ball will not undergo violent fission reaction, but will only fission very slowly, releasing very weak heat and radiation.

When not in use, put the ceramic balls into a honeycomb lead box and seal it. When needed, take them out and fill them into the channel.

After filling, you can turn on the neutron source, which uses polonium and beryllium.

When many small balls are accumulated, a chain reaction will occur when they are hit by neutrons from a neutron source, generating a large amount of heat, thereby heating the graphite. At this time, low-temperature helium flows through the surrounding channels, cooling the reactor core.

At the same time, the high-temperature graphite heats the helium passing through, and the high-temperature helium drives the turbine to rotate, thereby driving the generator to generate electricity.

Part of the generated electricity is used to compress the cooled helium and transport it to the reactor core to participate in the next cycle. The excess electricity is usable electricity.

According to Zhizi's simulation calculations, when the reactor operates at full power, it will have a power of 3 megawatts, of which about 2.4 megawatts can be utilized, and the energy utilization rate is about 80%.

The electricity generated can supply 2 households (8 kWh per household per day).

When her deskmate saw Wang Jiankun writing and drawing something incomprehensible, she was no longer surprised.

But he doesn’t study much normally, so how could he get such good results in the exam?
She was still a little unconvinced and thought about working hard to get into the top 30 in the grade in the midterm exam.

She ranked 56th in the last monthly exam, which is a slight improvement from when she first came in.

Wang Jiankun knew that his desk mate was not convinced. Although he occasionally asked him some difficult questions, he never asked him about study methods.

Perhaps he still felt that he was only relying on his gift of memory and had no other good learning methods.

After evening self-study, Wang Jiankun rode his motorcycle back to the scrap recycling station to check, and then rode to Yuyu Garden to listen to "Ham"'s chat.

Squad leader Wu Xiaoyi told him that he should not use his motorcycle at night in the future because it was very cold to ride at night.

Wang Jiankun knew that the squad leader had been riding for so long that the novelty was almost gone, otherwise he would have continued to ride no matter how cold it was with the same enthusiasm as at the beginning.

Wang Jiankun felt that it would be better for the squad leader not to use the car during this period, as it would be more convenient for him to use the car.

In the next few days, Wang Jiajiankun studied the NS equation problem during the day, and occasionally changed his mind to further improve the miniature nuclear reactor.

Some safety measures have been added, such as adding insurance measures in the event of an unexpected shutdown, so that the small balls in the core can be quickly dispersed into lead containers, so that the chain reaction is forced to stop and there will be no heat accumulation to cause danger.

In addition, a safe plan must be designed for the handling of the nuclear fuel after the reaction. The initial plan is to dig a vertical shaft 500 meters deep underground, and then dig a space at the bottom and seal it with lead.

At that time, the nuclear waste will be sealed in lead barrels and placed in underground space.

The evening time is spent on transportation.

Lead, copper and zinc were transported back from Dexing. A two-wheeled cart could carry 1.5 tons of goods at a time. Motorbikes were used to transport the goods twice every night without making any mistakes. They were transported to the passage behind the mountain when they were submerged.

At the same time, we did not forget to excavate the underground base. At this time, the 4th floor had been excavated, and the third floor had also started to excavate more than 300 cubic meters.

On Friday evening, after Wang Jiankun finished transporting the second truckload of metal, he began to build the elevator.
