Traveling through the sword to engage in military industry.

Compared with the confidentiality level of helicopters, the difficulty of information related to nuclear submarines is completely different.

For example, for the nuclear reactor, Ren Zhong spent a lot of effort to get an old prototype.

Main world, Jincheng.

"Mr. Ren, I have contacted a person who claims to have a complete set of OK-150 reactor design information. He claims to be Kurchakov's great-nephew, Beria Kurchakov-Zov. When the Big Bear disintegrated, it was his father who preserved the hard work of the meritorious physicist Kurchakov, which included four boxes of manuscripts and various design information.

I verified some of the footage he provided, which seemed to be the original version of the information, but all of this information was in Russia's Far East. Zoff insisted on asking for 100 million RMB, but he would not accept remote transactions, and would not scan the information into digital data and transmit it. According to him, the risk was too great and he could not risk his life to trade.

"If we want to trade, then we should go to his house in the Far East with cash to trade."

Nuclear physicist Professor Zhao Daqing told Ren Zhong that he didn't know what his employer was going to do with the information. As far as he knew, no one doing nuclear research in the country would be interested in something as outdated as OK-150.

It is so outdated, and compared with our own exquisite little pile, it is just an ancient piece of junk!

Besides, Zhao Daqing was worried about how to get through the border with so much cash. In addition, even if the information was garbage, it was still under the control of the Russians. How could he bring it back?
But Ren Zhong obviously didn't think so much about it.

"No problem. If he is willing to trade in the Far East, then we will go to the Far East to trade." Ren Zhong said easily.

Last year, he commissioned Zhao Daqing to collect relevant information on nuclear applications in other countries. He did not dare to do the particularly sensitive ones, but he was allowed to dig deep into the information related to nuclear power, at any cost, saying that he wanted to conduct a study on the development of early nuclear power around the world.

Of course, Zhao Daqing didn't believe what a liberal arts student like Ren Zhong could do with these things.

To be honest, in the main world, anything that has something to do with nuclear matters is kept highly confidential. On the physical side, even civilian facilities like nuclear power plants are now under strict security. No one dares to allow people to enter and exit the core part of a nuclear power plant for research, let alone any country that dares to sell its scrapped submarines.

Therefore, Ren Zhong's most common contact is with overseas information.

Of course, for these reasons, Ren Zhong allocated more than 50 yuan for this project to support Zhao Daqing in doing this.

A lot of information collected by Zhao Daqing was brought into the world of Bright Sword by Ren Zhong, which at least saved Professor Wu and his colleagues more than ten years of exploration time in the process of nuclear power development research.

With Zhao Daqing's contact information, Ren Zhong chose to go to the Far East alone this time.

Fortunately, the current tourist visa is very convenient. Ren Zhong quickly completed the procedures for leaving. After arriving in Mohe, he directly rented a suite and marked the suite as a return point. Then he followed the normal entry and exit procedures to the Far East city designated by Zoff.

"Mr. Zoff, I am very sincere." After the call, Ren Zhong opened a box of cash and showed it to Zoff. "This is the cash for the transaction. If there are no questions, I hope to complete the transaction as soon as possible."

The Zoff who met Ren Zhong was a typical Mao Zedong, with a big red nose, tall and strong body, and fluent English and Chinese. It seemed that he had dealt with Dongda a lot. As soon as he saw the red banknotes, his heartbeat suddenly accelerated.

"Mr. Ren, I am also sincere. Since you have prepared the money, I will definitely deliver it to you tonight." Zoff took a deep look at the bag of money that Ren Zhong put away and said solemnly. "What I have in my hand is definitely the original version, and its collection value is very high. I think Mr. Ren will be proud of collecting this piece of history after reading the information."

This thing has long been out of date, and was even taken away from the hospital archives by Zoff's father during the turmoil. No one in the hospital paid attention to it at that time, and Zoff did not think there was anything wrong with selling it.

As for how Ren Zhong takes these things out and returns to Dongda, he doesn't care. After getting the money, he will leave here. After all, this is just a temporary place where he decided to trade.

The economic situation in Russia is in a mess now. Zoff, a physicist, has been out of luck for a long time and has been barely making a living by doing odd jobs. Now he has acquired a huge fortune of 100 million. Even if it is RMB, it is absolutely hard currency in Russia and is very valuable.

So Zoff would never regret selling this ancestral material.

Of course, these things are garbage to most people in the main world. They are completely useless. Those who do nuclear research already have things that are several generations more advanced. Those who don't do nuclear research think these things take up too much space.

"No problem, Mr. Zoff, I hope we have a pleasant transaction." Ren Zhong said with a smile.

He wasn't too worried about being cheated.

After all, Zhao Daqing had verified part of the content of the information before, and it would be difficult for ordinary people to forge it so professionally and realistically.

Besides, it’s just one million RMB, which Ren Zhong can afford to lose.

He came here in person, naturally wanting to bring the information directly to the world of Bright Sword.

The transaction was successful. There was no problem with Ren Zhong's RMB. After checking the banknotes, Mr. Zoff readily gave Ren Zhong the information of the four large boxes.

Ren Zhong opened it and took a look. It was indeed a yellowed paper. He certainly couldn't understand the content, but after comparing it with a few verification photos provided by Zhao Daqing, he found that it was indeed taken from part of the manuscript. In this way, the transaction was perfect.

What's even more rare is that these materials basically have no time stamps, which saves Ren Zhong a lot of conversion work. He left these things in place for a few days and then moved them to the Bright Sword world, asking the people in the Bright Sword world to take photos and make a complete collection of photos, and then let Professor Wu and his team take these manuscripts away for research.

Ren Zhong did not attach much importance to this information. After all, it was an antique from half a century ago in the main world. In Ren Zhong's opinion, it was just for reference.

This early OK-150 small reactor has a core design height of 1.58 meters and an equivalent diameter of 1 meter, which gives a power density of 72 kW/L. The core is finely constructed and consists of 219 fuel assemblies arranged in a triangular grid, with the spacing between each assembly precisely controlled at 64 mm. Of these 219 assemblies, 189 contain 36 fuel rods each, while the other 30 contain 30 fuel rods each. This gives a total of 7704 fuel rods in the entire reactor core.

In terms of performance, the OK-150 pressurized water reactor has a single-pile thermal power of 90 megawatts, and the original design shaft power is 1 horsepower. The heat conversion efficiency is not high. From the power point of view, it is enough for now, but the fuel replacement cycle is too long, only three to five years. For a powerful weapon like submarines, this period of time is naturally not enough. So after purchasing this design material, Ren Zhong gave the research team the goal of at least increasing the fuel replacement cycle to more than 3 years, and not limiting it to the level of large submarines.

The performance and safety of this early rough and original version of the Damao had many problems in history. Ren Zhong also looked up a lot of information about its main defects, so he did not dare to install it on the ship at all and demanded that innovative improvements must be made on this basis.

Fortunately, small reactors have undergone decades of development and have gone through three or four generations of technological iteration and optimization. The technical development direction and basic improvement ideas of each generation of mobile reactors are not too confidential. Zhao Daqing has collected a lot of ideas about the defects and improvement directions of OK-150, plus the development trends of subsequent generations of advanced reactor types. Therefore, Professor Wu and others were able to see the development of several generations of nuclear reactor technology in the 50s. For geniuses like them, these ideas are the most valuable.

This has been a great inspiration to them. The domestic uranium industry has now reached a certain scale, with production capacity steadily increasing. The basic raw materials for the uranium industry are no longer as scarce as they were a few years ago, so there are now sufficient raw materials to carry out experimental construction work.

After the project team confirmed the completeness and correctness of Ren Zhong's OK-150 data, they began to organize personnel in three shifts to thoroughly study the contents of OK-150. On the other hand, they started to build the pile directly according to the initial version of OK-150, and built two test piles right away.

Now we are not so short of human and material resources, but we are more short of time. Everyone of them knows the significance of this thing to the University of Tokyo after it is developed. It is in no way inferior to the peace bomb, and may even be more important!

You have to know that there are too few things we can do to threaten the Rogue Eagles. Even the enhanced version of the 4-propeller C-54 transport aircraft can only barely reach Honolulu and Alaska. These places are on the edge of the Rogue Eagles and can't pose much of a threat at all.

What's more, given the bulkiness of transport planes, there is a high probability that the cargo will be intercepted on the road.

Therefore, if you want to truly threaten the Rogue Eagle, you have to rely on nuclear submarines, underwater assassins that come and go without a trace. Even if submarine-launched missiles have not been developed yet, just putting a nuclear weapon on a torpedo is enough to make the Rogue Eagle gasp.

In order to save research time, the project team built two reactors for separate research, one for the original version design and the other for conducting basic research on the principles of small reactors.

Another pile was designed with many redundant and replaceable parts, specifically for the OK-150 optimization design research. Based on the original pile, it tested the effects of different optimization methods.

In particular, there are two indicators proposed by Ren Zhong, one is to improve safety, and the other is to extend the fuel replacement cycle.

Although these indicators are difficult for people who have just started to get started with reactors, the current nuclear research team is an unprecedented team that has included several future Nobel Prize winners and young talents who are leading figures.

Therefore, with the constant collision of ideas among these geniuses, and the conditions provided to them by Ren Zhong far exceeding the conditions of the main world's historical time and space during the same period: now there is not only detailed information on the old pile design that forms a model, but also data, as well as powerful computer computing power to support it!

It can be said that their research conditions are something that even their Rogue Eagle peers envy, and their progress in this area is naturally faster than in the original time and space!
After the Peace Bomb, Ren Zhong moved the main world's knowledge and revealed most of the principles. The hydrogen bomb was completed almost overnight. In less than a year and a half, the ground test explosion was completed without much effort. At the weapons level, the nuclear research team had gone very far and basically did not need Ren Zhong to lead the way. With 10 tons of equivalent, 30 tons of equivalent, and one million tons of equivalent, what they are pursuing now is no longer getting bigger and bigger, but studying how to make something with a larger equivalent in the smallest possible volume.

Especially in conjunction with the development of rocket technology, we should develop missile nuclear eggs!
After being far ahead in weapons-grade research, the team's main focus has now shifted to nuclear power research. One is nuclear power generation, and the other is shipborne nuclear reactors!
The first generation of 100MW thermal power reactor for power generation has been put into trial operation, which is basically five years ahead of the world in realizing the prototype reactor of nuclear power generation. However, according to the nuclear power research roadmap provided by Ren Zhong, the first generation reactor is only for research and demonstration, and its safety and economy are not practical. Therefore, after completing the trial operation of the prototype reactor, the project team also began to work on the second generation of real commercial reactors and turned to the research of the pressurized water reactor, the ancestor of the new generation of commercial power generation reactors.

This prototype reactor has begun to contribute to the base's electricity supply. After being equipped with power generation equipment such as steam generators and steam turbines, the base has a very stable 25MW power supply capacity.

For the next step of research, the conditions at the base have been greatly improved. At least now there is sufficient electricity to provide heating in winter and cooling in summer for every room in the base.

The so-called "pressurized water reactor" refers to a reactor in which the uranium fuel element rods are placed in the middle of a tall boiler; the control rods that control the reaction rate enter from the top of the boiler; the water in the boiler reaches 300 degrees and 150 atmospheres of pressure; the steam is output through the "steam generator" to drive the turbine to generate electricity.

The second-generation reactors were basically mature in the 70s in the main world, more than 15 years ahead of the current world of Liangjian. Of course, the technical difficulty is relatively large. However, in order to achieve safe operation for more than 50 years, the core technology of the second-generation reactors must be mastered before nuclear power plants can be promoted domestically and globally.

You know, this is a huge market. Hundreds of nuclear power plants have been built around the world, and each nuclear power plant costs tens of billions or even hundreds of billions of US dollars to build. So Ren Zhong has also set his sights on this market. Just for these two piles, he has invested at least tens of millions of yuan in huge research funds from the Bright Sword world. After all, uranium is not easy to obtain in this time and space.

With the technical achievements of the first-generation prototype reactor and the relatively complete data of OK-150 provided by Ren Zhong, Professor Wu's team quickly completed the construction of the OK-150 prototype reactor, realized a miniaturized and movable 90MW-level small reactor, and successfully started the small reactor and connected it to the steam generator to produce a 90MW-level steam thermal power output!

Of course, converting this thermal power into wheel axle propulsion requires further research from the power department.

Calculated according to the ratio of thermal power to shaft power, a small reactor with a thermal power of 90MW can be converted into a shaft power indicator for propulsion power. According to the original level of the OK-150, it is about 1 horsepower. However, after optimization, Professor Wu and his team's goal is to achieve 3MW, which is equivalent to 15 horsepower, which is slightly lower than the power of the LM2 gas turbine.

However, compared to the S2W nuclear reactor in the early days of the Rogue Eagle main world, this power is still a little bit larger.

According to historical data from the main world, the reactor compartment of the Nautilus, Rogue Eagle's first nuclear submarine, was equipped with an S2W nuclear reactor with a power of 15000 horsepower.

Therefore, if Professor Wu's team can improve the safety of the OK-150 reactor and increase the fuel replacement cycle to more than 10, the power of the first generation of nuclear-powered submarines will basically be completed.

The solution to this problem is actually simple, but how to experiment to find a better balance requires the efforts of Professor Wu’s team.

According to the preliminary reference range given by Ren Zhong, as long as the uranium content is increased to about 21%, the goal of a lifespan of more than 10 years can be achieved. (End of this chapter)
