Chapter 64 Return to base and ignite the reactor
After setting off from Kunshan County Pier at 9 a.m., Wang Jiankun slowly increased the speed of the boat to 30 knots and rushed upstream.

After returning, this ship will not plan to sail to Shanghai or the sea again. The American Navy must have recorded this ship, and if it appears nearby again, it will definitely be discovered by someone with ulterior motives.

If we want to set up a transport fleet in the future, we will go back and make a diesel version.

The speed does not need to be so fast. The maximum speed is 20 knots and the economic speed can reach 15 knots.

This speed is 50% faster than a passenger ship, and it is more than 1 times faster than a cargo ship.

Wang Jiankun's caution was not meaningless. Just after Wang Jiankun sabotaged the Perry-class destroyer and escaped, the intelligence officer who turned on the backup power supply sent the hydrological information and photos of Wang Jiankun's ship to the base.

Moreover, the Chinese Navy has also discovered the abnormal situation off the coast of Shanghai.

Because Wang Jiankun's K200 was too small, the shore-based radar's sea search distance and clutter filtering capabilities were relatively poor, so when Wang Jiankun's ship sailed 10 nautical miles out of the coastline, it could not be detected.

But the situation was different when the Perry-class destroyer came over. The shore-based radar detected it when it approached 50 nautical miles.

Seeing it heading towards the coast, the personnel on duty at the radar station notified their superiors while keeping a close eye on the uninvited guest with radar.

When we saw the ship slowing down and circling 40 nautical miles offshore, after a while its speed suddenly dropped and it stopped.

The staff on duty quickly reported the situation to their superiors, who also found it strange and sent two warships to check out the situation.

The Americans have such an advanced warship parked at our doorstep. I don't know whether it is out of good intention or bad intention, but it is necessary to get rid of it.

After receiving the order, the two warships on combat duty headed for the designated sea area and it took them more than 40 minutes to arrive.

The moonlight illuminated the sea very brightly. Through the telescope, I could see the warship standing there motionless. It must have dropped the anchor chain.

However, after such a long time, the sky was already slightly bright, and the warship sent divers into the water, and the two warships patrolling back and forth nearby could see it clearly.

The two divers surfaced shortly after they went into the sea, and asked the people on the warship to lower down two tools for cutting cables.

Seeing this situation, the two warships responsible for surveillance understood what the problem was. It was probably that the propeller was entangled in fishing nets or ropes, so it lost its ability to move.

The two captains monitored and reported the situation to their superiors.

The two divers surfaced again shortly after they went down, signaling the people on the ship to pull them up.

Seeing this, I thought the two divers had finished clearing the cables or fishing nets, but I didn't expect that the warship was still stationary and didn't start the gas turbine.

After waiting quietly for more than an hour, another warship with the American flag appeared on the sea.

This warship was much smaller, and the two warships did not receive any notification from the shore-based radar station, so they probably did not discover it.

The small warship sailed close to the Perry-class destroyer, circled it, and then approached the stern of the Perry-class.

The two sides communicated on the walkie-talkie for a while, and then six divers came out of the warship.

Two people went down in a group with cutting knives to cut the cable. After 10 minutes, another group would come up to take over. It took two hours before they stopped taking turns to go into the water.

Then the rescue ship started moving and moved several hundred meters away from the Perry-class ship. Smoke finally began to come out of the chimney of the Perry-class ship.

It seems that the obstacle entangled in the propeller shaft has been cleared. I don't know if the American divers are not capable enough or what, but it takes so long to cut the cable, and so many people have to take turns to cut it.

What the captains of the two Chinese warships didn't know was that the cables made by Wang Jiankun were very strong. He was afraid that they would not be able to hold the propeller firmly, so he added thin steel wire inside the cables.

The first two American divers who went into the water thought it was an ordinary cable at first. After cutting one layer, they could not cut it anymore. After looking carefully, they realized that it was a cable mixed with thin steel wires, so they went back to the warship to ask for help.

After the Perry-class ship started moving, it collected the anchor and turned around and headed towards the Okinawa base with the rescue warships.

This trip was a complete disgrace. Fortunately, the Chinese warships nearby were unaware of the internal situation, otherwise they would have embarrassed themselves in front of one billion Chinese people.

Captain Lawrence was very upset at this time. He didn't gain anything from this trip and even damaged the warship. The internal circuits needed to be replaced on a large scale and the equipment needed to be overhauled.

Because the distribution box caught fire and the propeller locked, the warship stopped abruptly and the best time to extinguish the fire was missed. As a result, the fire burned several cabins and several people were knocked unconscious by the poisonous smoke.

Although he did not die after emergency treatment, he was certain to retire because he inhaled a large amount of toxic smoke into his lungs and would be a disabled person from now on.

Although these two consecutive failures were initially judged to be accidental, Lawrence did not believe in such a coincidence. He was just about to take action against the strange boat when his own boat broke down. This must be related to the strange boat.

Although that ship did not seem to have any weapons on the surface, and no one knew how it caused its own ship to malfunction, it was clear from its subsequent reaction that it was the one who did it, because as soon as the malfunction occurred on its side, it actually escaped at a speed of almost 30 knots.

When it comes to shipbuilding in today's world, if the United States admits to being second, no country dares to claim to be first, so this ship that can run at 30 knots must be extraordinary. This speed can generally only be achieved by high-speed speedboats or high-speed destroyers, and nuclear-powered aircraft carriers when launching carrier-based aircraft. No other ship can have such a high speed.

I have to tell the intelligence agencies about my analysis when I get back and ask them to focus on whether the various shipyards have the ability to manufacture ships of this shape.

Not to mention that the Chinese Navy had watched enough of the Americans’ diving and rescue drama at sea.

Wang Jiankun's K200 high-speed transport ship was traveling at high speed upstream of the Yangtze River. The captains on the river looked up one after another. Wang Jiankun thought, just watch it, this is the last highlight moment of this ship.

It will be stored when we get back, and will be remodeled when we have time. The shape of the upper deck will be similar to the passenger ships currently sailing on the Yangtze River, while the lower deck and the bottom can be designed for high speed.

We stopped at Anqing Wharf for a short rest at noon, refilled the gas and then set off for Poyang County.

At around 8 o'clock in the evening, they arrived at the location of the hidden experiment No. 1, lifted the collected uranium and several other elements onto experiment No. 1, then used super powers to expand the cave, drove K200 in, and did some hiding at the entrance of the cave.

Then we drove Experiment No. 1 at a speed of 35 knots to the temporary dock in Wuyuan County.

We arrived at the temporary dock at 12 o'clock at night, loaded dozens of cans onto a two-wheeled trailer, and then towed them to the base on a motorcycle.

After arriving at the base, he checked the monitoring equipment and found nothing unusual, so he washed up and went to sleep. Wang Jiankun was very tired after three days and three nights of busy work, and soon he began to snore.

Wang Jiankun was woken up by the alarm clock on Friday morning. He wanted to sleep in a little longer, but he thought that he had already taken leave for three days. It might be difficult to cancel the leave if he did not report it today. Otherwise, it would be difficult to ask for leave next time.

So I got dressed shivering, washed up, and then rode my motorcycle to school.

When I arrived at school, I first went to the class teacher's office to report to him, indicating that he had returned to school on time for class, and then went back to the classroom for morning reading.

Yu Zirun, one of the seven disciples and a classmate at the same table, asked, "Wang Jiankun, did you have fun outside these days?"

"It was not fun. I almost got bullied by a bully. Luckily I ran fast." Wang Jiankun told Yu Zirun a bunch of nonsense stories about encountering bullies, and then gave her some advice on English listening and reading aloud.

Wang Jiankun did not go to the cafeteria for breakfast. Instead, he ran to the mobile stall at the door and bought some steamed cakes, eating them all the way to the recycling station.

He went there and checked the accounts for the past three days with Ye Wei and his wife, and then used his superpowers to purify the transported rare earths and manufacture the various necessary materials.

All of this was changing inside the box, and the two did not notice anything unusual.

After finishing all this, Wang Jiankun went back to school to attend classes, where he continued to learn microscopic physics from Zhizi.

In the daytime class, the teachers seemed relieved to see Wang Jiankun come back, fearing that such a promising top student would run away and never come back. Wang Jiankun also cooperated with the teachers to answer some difficult questions, which made the teachers feel at ease.

After class in the afternoon, Wang Jiankun bought some dry food and went to the waste recycling station. Then he rode his motorcycle to transport the 50 kilograms of liquid helium that his uncle had helped him buy from Hong Kong back to the underground base. He was going to start using uranium to conduct fission experiments.

Before the experiment began, Wang Jiankun used his superpowers to dig out 150 cubic meters of space on the second layer, leaving some abilities to transport elements for the experiment.

The first step was to turn on the power to check the experimental reactor to see whether all components were operating normally. After confirming that everything was normal, Wang Jiankun began to make nuclear fuel balls.

To be on the safe side, he planned to control the uranium 235 enrichment in the experimental nuclear fuel balls to around 3.5%. This would allow the experimental reactor to start without emitting too much energy, while also allowing for inspection of whether each component met the design requirements.

After all, we had only simulated it a few times using electricity and liquid nitrogen before, but nuclear leakage prevention had not been actually tested, so we had to do more experiments to ensure safety.

After studying during the day, Wang Jiankun has a better understanding of microscopic structures. He can now quickly magnify atoms to observe the nucleus, and can distinguish the protons and neutrons in the nucleus.

However, it is not possible to use superpowers to manipulate protons and neutrons because my microscopic control capabilities have not yet reached that level.

Wang Jiankun first mobilized the elements stored in the base to make 3 small ceramic balls, then took a lead can full of uranium, used his superpowers to extract the uranium 235 from it and distributed it into the 3 small balls.

每个小球分配23.7毫克的铀235，然后再放入653.4毫克的铀238，这样每个小球内铀235的丰度就是3.5%了。

Because I was not very skilled yet, it took me more than two hours to extract uranium 235, and it was very energy-consuming, but I finally completed this important step.

In the future, as my mental strength and proficiency increase, my speed should get faster and faster.

The nuclear fuel balls are loaded into a special container and placed in the feeding device of the experimental reactor. Then the switch is pressed and the small balls are evenly filled into the pores of the graphite columns.

Then turn on the neutron source, which is made of a metal called beryllium.

Beryllium has many isotopes, including beryllium 6~12 and beryllium 14. Among them, only beryllium 9 is stable. The other seven will decay naturally and release a large number of slow neutrons. These slow neutrons are projectiles that can hit uranium 7 and cause it to fission.

The nuclear fuel balls in the microreactor begin to fission under the bombardment of slow neutron shells. Fission releases a large amount of heat to heat the graphite, and at the same time releases a large number of fast neutrons. The fast neutrons will slow down when passing through the graphite. The slowed down slow neutrons will turn into shells to bombard uranium 235. In this way, a chain reaction occurs, and the nuclear fuel balls are ignited and release heat.

After observing that the temperature inside the reactor had steadily risen to 1 degrees, Wang Jiankun turned off the neutron source to see if the reaction could continue.

After observing for a few minutes, it was found that even without the neutron replenishment from the beryllium neutron source, the fission reaction in each fuel ball was still proceeding at a certain speed, which showed that the nuclear flame had been ignited successfully, and the next step was to convert the released energy.

At this time, the core temperature had reached more than 1500 degrees. Wang Jiankun opened the valve of the helium storage tank, and the high-pressure liquid helium entered the energy circulation pipeline. When it encountered the high-temperature graphite, the helium was heated to more than 1200 degrees. The high-temperature helium rushed out of the core and after passing through a booster expansion device, the temperature dropped a little but the pressure increased several times.

High-temperature and high-pressure helium is first sent into the high-pressure steam turbine to drive the turbine to rotate. The helium whose pressure is reduced to a certain value is then introduced into the low-pressure steam turbine to generate electricity, and then flows through the compressor to be compressed and enter the next cycle.

As the nuclear reaction continues, the core temperature continues to rise slowly until it reaches 2000 degrees, then it stops rising. This is because the helium takes away the heat to generate electricity.

Wang Jiankun checked the operating status of the high-pressure steam turbine and found that the intake temperature was 1200 degrees and the pressure was 10 atmospheres, and the gas outflow temperature was 1000 degrees and 6 atmospheres.

The helium outflow temperature of the low-pressure turbine is 600 degrees and the pressure is 1.2 atmospheres.

The electricity generated by the high-pressure steam turbine is used to maintain the internal power demand of the experimental reactor, and the power generation capacity of the low-pressure steam turbine is 50KW.

These values ​​are within the simulation range after Sophon designed this experimental reactor, so it can be said that this experimental reactor is usable.

Wang Jiankun has been using his superpowers to monitor the entire experimental reactor, checking the process of nuclear fission, the condition of the carbon nucleus after being hit by neutrons, and the wear and aging of various moving parts and connecting parts under high temperature and high pressure.

After the experimental reactor had been running stably for two hours, Wang Jiankun pressed the stop switch and the nuclear fuel balls were stored in the lead box below. At this time, the helium circulation was still going on, taking away the heat of the core and the residual heat of the nuclear fuel balls.

Wang Jiankun observed that the reaction of the uranium nucleus stopped after leaving the graphite column. Although the residual fission still sporadically released neutrons, the released fast neutrons could not trigger a chain reaction without the slowdown of graphite. Slowly, the temperature of the nuclear fuel ball dropped to room temperature. The uranium 235 inside was just undergoing conventional decay, and it was safe to shield it with an ordinary lead box.

After the core temperature drops to a certain level, the experimental reactor automatically connects to an external power source to allow the helium to continue circulating and cooling until the temperature reaches normal temperature. The helium is also compressed into a gas tank by a recovery compressor and stored.

This successful experiment gave Wang Jiankun the confidence to build a 3-megawatt reactor in the future. In addition, observing the uranium nucleus being shattered by neutrons gave Wang Jiankun the idea of ​​building a high-energy physics laboratory.

Because Peter and his uncle were already helping to collect the world's top scientific research progress and ideas for theoretical knowledge, but the specific experimental data were kept confidential by those laboratories, it was difficult for Wang Jiankun to improve as he only had conclusions but no process.

It would be better to build a laboratory by yourself, starting with simple particle experiments. As your knowledge grows and your research deepens, you can constantly update the equipment. Then you can build a more advanced particle collider to help you observe and study microscopic structures.
