#388 - Small pile of big black fish starts from OK150
Compared to the level of secrecy surrounding helicopters, the difficulty of obtaining information related to nuclear submarines is on a completely different level.
For example, Ren Zhong spent a lot of effort to get his hands on an early prototype of a nuclear reactor.
Main World, Jincheng.
"Mr. Ren, I have contacted someone who claims to have a complete set of OK-150 reactor design documents, claiming to be Beliya. Kurchatov. Zoff, the great-nephew of Kurchatov. When the Big Bear disintegrated, it was his father who preserved the hard work of the meritorious physicist Kurchatov, a full 4 boxes of manuscripts and various design materials.
I verified some of the photographed image fragments he provided, suspected to be the original version of the data, but these data are all within the Far East territory of Da Mao. Zoff insists on a price of 1 million RMB, but he does not accept remote transactions, let alone scan the data into digital data for transmission. According to him, the risk is too great, and he cannot risk his life to trade."
"If we want to trade, then bring cash to his home in the Far East to trade."
Nuclear physicist Professor Zhao Daqing said to Ren Zhong, he didn't know what his employer was buying these materials for. As far as he knew, no one in the country engaged in nuclear research would look at something as outdated as the OK-150.
It's too outdated, compared to our own Linglong small pile, it's an old waste!
What's more, Zhao Daqing was worried about how to get so much cash through the border? In addition, even if those materials are garbage, they are still under the control of Da Mao, how can they be brought back?
However, Ren Zhong obviously didn't consider so much.
"No problem, if he is willing to trade in the Far East, we will go to the Far East to trade." Ren Zhong said easily.
Last year, he entrusted Zhao Daqing to collect relevant information on nuclear applications in other countries, not daring to do anything particularly sensitive, but letting him go to dig into nuclear power-related information at all costs, saying that he wanted to do a research work on the development of global early nuclear power.
Of course, Zhao Daqing didn't believe that a liberal arts student like Ren Zhong could do anything with these things.
To be honest, in the main world, anything that touches the edge of nuclear power is highly confidential. In terms of physical objects, even civilian facilities such as nuclear power plants are now heavily guarded. No one dares to let anyone casually enter and exit the core part of the nuclear power plant for research, let alone any country dare to scrap and sell submarines.
So Ren Zhong's most contact is with overseas information.
Of course, for these, Ren Zhong gave this project more than 500,000 yuan in funding to support Zhao Daqing in doing this.
Many of the materials collected by Zhao Daqing were imported by Ren Zhong into the Bright Sword world, at least saving Professor Wu and others more than ten years of exploration time in the development and research process of nuclear power.
Taking 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 got the procedures for going out. When he arrived in Mohe, he directly rented a suite. Ren Zhong marked this suite as a return point. Then, according to the normal entry and exit procedures, he arrived at the Far East city designated by Zoff.
"Mr. Zoff, I am very sincere." After getting in touch, Ren Zhong directly opened a box of cash to show Zoff, "This is the cash for the transaction. If there are no questions, I hope to complete the transaction as soon as possible."
Zoff, who met with Ren Zhong, was a typical Da Mao person, with a red nose, tall and strong body, and fluent English and Chinese. It seemed that he had dealt with Dongda a lot. When he saw the red banknotes, his heartbeat suddenly accelerated.
"Mr. Ren, I am also very sincere. Now that you have prepared the banknotes, tonight, the things will definitely be delivered to you." Zoff took a deep look at Ren Zhong's banknote briefcase and said solemnly. "What I have in my hand is definitely the original version. The collection value is very high. I think Mr. Ren will be proud to collect this piece of history after reading those materials."
This thing is long outdated, and even Zoff's father took it away from the hospital's archive during the turmoil. At that time, no one in the hospital paid attention. Zoff didn't think there was anything wrong with selling it.
As for how Ren Zhong takes it out and returns to Dongda with these things, he doesn't care. After getting the money, he will also leave here, after all, this is just a temporary place where he decided to trade.
Now the economic situation of Da Mao is a mess. Zoff, who is engaged in physics, has long had no good job, barely making a living by doing odd jobs. Now that he has received a huge fortune of 1 million, even if it is RMB, it is definitely a hard currency in Da Mao now, very valuable.
So Zoff will not regret selling this ancestral material at all.
Of course, these things are garbage data for most people in the main world. It can be said that they are useless. Those who are engaged in nuclear research already have several generations of more advanced things. Those who are not engaged in nuclear research feel that these things take up space when they get them.
He came here in person, naturally wanting to bring the information directly to the Bright Sword world.
The transaction was very successful. Ren Zhong's RMB had no problems. After Mr. Zoff verified the banknotes, he very readily gave Ren Zhong four large boxes of materials.
Ren Zhong opened it and looked at it. It was indeed yellowed paper. Of course, he couldn't understand the content, but comparing a few of the verification photos given by Zhao Daqing, the comparison was indeed taken from a part of the manuscript. In this way, the transaction was very perfect.
What's even more rare is that these materials basically have no time stamp, which saves Ren Zhong a lot of conversion work.
He stayed in place for a few days and transferred these things to the Bright Sword world. He first asked the people in the Bright Sword world to take photos and make a complete collection of photos, and then let Professor Wu and others take the original manuscripts away for research.
Ren Zhong didn't pay much attention to this information. After all, this is an antique from half a century ago in the main world. In Ren Zhong's opinion, taking it is 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 calculates its power density to be as high as 72 kilowatts/liter. The internal structure of the core is fine, consisting of 219 fuel assemblies, which are arranged in a triangular grid with the spacing between each assembly precisely controlled at 64 mm. Among these 219 assemblies, 189 assemblies each contain 36 fuel rods, while the other 30 assemblies each contain 30 fuel rods. Thus, there are 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 13,000 horsepower. The thermal conversion efficiency is not high. From the perspective of power, it is barely enough now, but the fuel replacement cycle is too long, only three to five years. For a big killer like a submarine, this period of time is naturally not enough. Therefore, after purchasing this design material, Ren Zhong's goal for the research team is to increase the fuel replacement cycle to more than 10 years, and not be limited to the level of Da Mao.
The performance and safety of this early crude original version of Da Mao had many problems in historical time and space. Ren Zhong also checked a lot of information about the main defects, so Ren Zhong did not dare to install it on the ship with confidence, and required that it must be innovated and improved on this basis.
Fortunately, after decades of development, small reactors have undergone 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 the OK-150. Coupled with the development trends of subsequent generations of advanced reactor types, Professor Wu and the others were able to see the technological development context of several generations of nuclear reactors in the 1950s. For geniuses like them, these ideas are the most valuable.
This was a great inspiration to them. Now, China's uranium industry has formed a scale, and its production capacity has steadily increased. The basic raw material part of the uranium industry is no longer as scarce as it was a few years ago, so there are now sufficient raw materials to carry out experimental construction work.
After the project team confirmed the integrity and correctness of Ren Zhong's OK-150 data, they began to organize personnel in three shifts to study and thoroughly understand the OK-150 content. On the other hand, they directly started working on the initial version of the OK-150 reactor, and they built two experimental reactors right away.
Now there is no shortage of manpower and material resources, but time is relatively short. Everyone knows the significance of this research for Dongda after it is completed. This is something that is not inferior to the peace bomb, and even more important!
You must know that for the rogue eagle now, there are too few things we can use to threaten them. Even the enhanced version of the four-engine propeller C-54 transport aircraft can barely reach the Honolulu area and Alaska, which are the peripheral areas of the rogue eagle and cannot play much of a threatening role.
Besides, with the clumsiness of a transport plane, it is highly likely to be intercepted on the road.
The latest novels are first published on Liu Jiu Shu Ba!
Therefore, if we want to truly threaten the rogue eagle, we must rely on nuclear submarines, underwater assassins that come and go without a trace. Even if submarine-launched missiles have not yet been developed, just putting a nuclear warhead on a torpedo is enough to make the rogue eagle gasp.
In order to save research time, the project team built two reactors to study separately. One is used for the original design, specializing in the basic research on the principles of small reactors.
The other reactor is designed with many redundancies and replaceable parts, specializing in OK-150 optimization design research, based on the original reactor, to test the effects of different optimization methods.
Especially targeting the 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 with reactors, the current nuclear research team is an unprecedented dream team, bringing together several future Nobel Prize winners and young geniuses who are leading figures.
Therefore, under the continuous collision of ideas of these geniuses, coupled with the conditions provided by Ren Zhong that far exceed the conditions of the same period in the main world's historical time and space: now there is not only detailed information on the design of an old reactor that has formed a model, but also data, and the support of powerful computer computing power!
It can be said that their research conditions are the envy of their rogue eagle counterparts. Progress in this area is naturally faster than in the original time and space!
After the peace bomb, Ren Zhong transported the knowledge of the main world and revealed most of the principles. The hydrogen bomb was almost completed in one fell swoop. In less than a year and a half, the ground test explosion was completed without much effort. At the weapon level, the nuclear research team has gone far and basically does not need Ren Zhong to lead the way. 100,000 tons equivalent, 300,000 tons equivalent, and millions of tons equivalent, what they are now pursuing is not getting bigger and bigger, but researching how to make things with a larger equivalent in as small a volume as possible.
Especially in conjunction with the development of rocket technology, develop missile nuclear warheads!
After the weapon-level research has been far ahead, the main force of the team has begun to shift to nuclear power research, one is nuclear power generation, and the other direction is shipboard nuclear reactors!
The first generation of 100MW thermal power reactor for power generation has been test-run, basically leading the world by more than five years to achieve the prototype reactor for 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. Safety and economy are not practical, so after completing the prototype reactor test run, the project team also began to enter the second generation of real commercial reactors, turning to research the pressurized water reactor, the ancestor of a new generation of commercial power generation reactors.
And this prototype reactor began to contribute to the base's power supply, equipped with steam generators and steam turbines and other power generation equipment, allowing the base to have a very stable 25MW power supply capacity.
For the next step of research, the base's conditions have been greatly improved. At least now there is ample power to provide heating in winter and cooling in summer for every room in the base.
The so-called "pressurized water reactor" refers to the uranium fuel element rods of the reactor core being placed in the middle of a tall boiler; the control rods that control the reaction speed enter from the top of the boiler; the water in the boiler reaches 300 degrees and 150 atmospheres; the 'steam generator' outputs the steam to drive the turbine to generate electricity.
The second generation of reactors basically matured in the 1970s in the main world, leading the current Liangjian world by more than 15 years. Of course, the technical difficulty is relatively high, but in order to achieve more than 50 years of safe operation, the core technology of the second generation of reactors must be overcome before nuclear power plants can be promoted domestically and globally.
You must know that this is a huge market. Hundreds of nuclear power plants have been built around the world, and each nuclear power plant costs billions or hundreds of billions of dollars to build. Therefore, Ren Zhong has also set his sights on this market. He has invested at least tens of millions of yuan in research funds in the Liangjian world for these two reactors alone, 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 the OK-150 provided by Ren Zhong, Professor Wu's team quickly completed the construction of the OK-150 prototype reactor, realizing a miniaturized, mobile 90MW small reactor, and successfully started the small reactor, connecting the steam generator to generate a 90MW steam heat power output!
Of course, to turn this thermal power into shaft propulsion, the power department needs to conduct further research.
According to the ratio of thermal power to shaft power conversion, a 90MW thermal power small reactor, converted into shaft power indicators for propulsion, is about 13,000 horsepower according to the original level of Da Mao OK-150, but after optimization, Professor Wu and their goal is to achieve 15MW, which is equivalent to the level of 20,000 horsepower, slightly lower than the power of the LM2500 gas turbine.
However, compared to the early S2W nuclear reactor of the rogue eagle's main world, this power is still a little bigger.
According to historical data from the main world, the rogue eagle's first nuclear submarine, the Nautilus nuclear submarine, had an S2W nuclear reactor installed in the reactor compartment, with a power of 15,000 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 years, 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 point requires the efforts of Professor Wu's team.
According to the initial reference range given to them by Ren Zhong, as long as the uranium content is increased to about 21%, the goal of achieving a lifespan of more than 10 years can be achieved. (End of this chapter)
