"Very good, Mr. Li, you can introduce us to this nuclear power plant...... "Wen Desi said with a smile.

"Mr. Wen, the reactor in front of us is a fourth-generation reactor, but the first two generations only exist on the drawings, because according to our many simulation tests, it was found that their safety is very low, so they have not been actually built. We must thank our colleagues at the Institute of Computer Science, who have made computers and compiled various software, which have brought immeasurable help to our research work. Otherwise, we have to spend a lot of time, money, manpower and material resources to test one by one. ”

Li Tianye didn't mention his own profession first, but praised the computer first. Of course, what he said is also true, and the help of computers in scientific research cannot be overpraised. Needless to say, just one computing power can explode manpower many times. With the strong computing advantage, the system development cycle speed of design, testing, design modification, re-testing, etc. is much higher, so China's technological development speed is much faster than that of Europe and the United States. Not to mention, there are also those materials of later generations.

Except for a small number of people in the military, government agencies, and research institutes, the vast majority of people are still unable to touch this kind of high-tech product, so they cannot have it in every household like in later generations, so they still cannot directly use the advantages of this computer in many fields.

However, this is not out of the question, in 1922 China took out the tube computer, and also announced on the news network that "China has successfully developed an electronic computer." Well, who dares to say that the tube computer is not an electronic computer? In addition, a group of experts have been able to build momentum in the academic circles and come up with a number of papers involving computer principles.

Subsequently, the Chinese government dispatched a number of computers and set up computing centers in various provincial capitals and large cities to provide computing services to the outside world. That is to say, companies, schools and other enterprises and institutions with the qualifications to use first apply, and then give formulas, parameters, processes, etc. The computing center then arranges a team to program the calculations, and then hand over the calculation results to the applicants.

Of course, the external propaganda is the use of "tube computers", which is used to hide people's eyes. Therefore, applicants only know that the computing center has tube computers and has strong computing power to provide services, but they do not know the real situation behind them, in fact, they are at least the fourth generation of computers that serve them.

In fact, this kind of use of computing centers to serve the public is not very unusual. In the 60~80s in the original time and space, before the advent of PCs, people who needed to do calculations used this method to apply for the use of mainframes. He was just 40 years ahead of schedule.

Because computers are so useful, there are too many places to use them, so although China's computers are not popular, the number of people who use them is not small, even if there are not 100,000 people, there are always 80,000 people, so it is definitely impossible not to leak out at all.

In this case, it is better to simply selectively make it public. You know, the best way to hide is not to keep it completely secret at all, because it is not realistic, the best way is to selectively reveal something, and then half-truth, with some specious information, mislead the opponent, so that they willingly, or even very actively turn on another road, this is the king.

That's right, just like the last airship winning theory, the things about computers announced by China this time are also the same as the fine tradition of "bringing people into the ditch". There is no problem with those theories, they are all true, and if anyone really studies those theories, they can indeed make electronic computers, and these computers can indeed be used, but the cost and performance are very impressive. Uh, who would dare to say that a tube computer is not an electronic computer?

Moreover, Wen Desi also had the ill faith of the experts to publish several papers on "tube miniaturization", expressing with sufficient arguments that in addition to the great role of "tube miniaturization", he described a very bright prospect, and of course there was nothing wrong with these theories.

In fact, in this era, many theories of electronic computers are already big deals. In 1930, the American scientist Vanneva Bush built the world's first analog computer (large differential analyzer). The so-called analog means that it uses the angle of rotation of the gears to simulate the calculation results, similar to the principle of the Leibniz multiplier, which is not yet a digital computer in the true sense of the word. Born in 1944, ENIAC was the first generation of digital electronic computers and the ancestor of later computers.

However, due to the butterfly effect caused by Wen Desi, the technological development of the original plane is faster than that of the original space-time, and the development of computers is so. As mentioned earlier, as early as before the founding of the People's Republic of China, the world's number one "self-working five marks" sold a batch of "electromechanical computers" that calculated and shot all dollars to the Germans, and later sold a batch of "electromechanical computers" for warships. Later, the Americans also knew about the "new type of computer" in China, and they also bought a batch of them.

I don't know if they were inspired by this, but in 1922 the Americans came up with an analog computer, eight years ahead of the original time and space. Similar research is being carried out by the Germans, and the finished product is on the horizon.

But this time, the inventor was not the Bush classmate from history, but a few unknown engineers. Bush, who is known as the "father of computers," has become a "victim" of the "Pig Teammates Program" and has been led to another path by a good friend and has become his own colleague. At present, he is already a well-known oil merchant in the United States, an emerging millionaire, relying on the oil fields he found in Angola, making a lot of money, counting money and cramping, he is much richer than he was in the original time and space, and his net worth is at least dozens of times more.

Less than a month after the advent of their analog computer, China announced the news of the invention of the electronic computer, which made the Americans extremely depressed and suddenly enlightened.

Of course, what they didn't know was that Wen Desi chose this time to release this news, and he also had considerations. Because "bringing people into the ditch" is also a technical job, and it can't be too early or too late. It's too early, there are too many variables, maybe people will turn back on the right path. It's too late, and if the foundation is too good, you won't be fooled. Analog computers are just the pre-technology of digital computers, and this point in time is just right.

After the news came out, not only the academic circles were in an uproar, but also the governments of the major powers were red-eyed, as long as the government with a normal IQ could see the importance of computers to the development of the country. If nothing else, how much time and manpower can be saved by a government's statistical and budgetary work alone. They came to their homes to buy them, but they were all refused.

Do you want to buy the actual tube computer? Sorry, this is China's top secret, the highest scientific and technological achievement, and it is absolutely not for sale! Well, the real reason is that China has only built four tube computers, all of which are used for display and display, one each in Hanjing, Wuhan, Shanghai, and Neijiang. As for the tube computers in the computing center, ahem, they are all just shells.

However, for the great powers, it is nothing if China does not sell, and this kind of thing is the same for them. But what the Chinese can come up with, can't I study the principle of the cold and noble country X? Isn't it an electronic computer, and the relevant theory has been in the 19th century, what's the big deal?

Now experts from various countries are plunging headlong into these two big pits with full passion, and it is difficult to say when they will be able to climb out, because these things are not as easy to expose as the "airship winning theory". Anyway, the Soviet Union, which was in the original time and space, squatted in the big pit of "tube miniaturization" for decades and did not climb out.

As for whether the leaked information from those users will make the powers suspicious, there is no need to worry at all. First of all, these computers in China usually lock the chassis, and there are special personnel responsible for maintenance, as well as surveillance cameras and guards. Users can't say that they can't see the structure and parts inside, and even if they do, most people can't figure out what is inside.

Besides, even if they leak the shape of the parts, it is impossible for foreign countries to understand what it is, and it is impossible for them to know what large-scale integrated circuits are with the electronic knowledge they have now, and they do not have this concept.

As for peripherals such as monitors, keyboards, mice, printers, and software, there is no need to worry. Although according to the theories provided by China, it is not impossible to develop these peripherals suitable for the use of tube computers, but this is really not an easy thing to achieve, and those signal conversion devices alone are enough for them to catch blind.

To put it simply, according to the hole dug by China, if you want to make these peripherals, you will probably need a signal conversion device about the size of the computer host, and the size of the computer will be half that of the historical ENIAC. Not to mention those application software, even if they do make it, as long as they think of "programming application software in a tube computer", the picture is too beautiful to see.

As for whether they will wake up, Mr. Wen will never consider this kind of problem, anyway, this kind of thing is a pit to death.

..............................................................................

After praising his colleagues in the computer field, Li Tianye began to introduce the new nuclear power plant in front of him to Wen Desi.

"Mr. Wen, what we really put into practical verification is the third-generation reactor, to be precise, the pressurized water reactor, the first reactor was started in October 1917, and it has been running safely until now, without any accidents in the middle, which proves that the third-generation reactor is very safe. If there is not a better fourth-generation reactor, the third-generation reactor can be put into commercial operation. ”

"Well, of course. But we in China will do the best if we want to, and now we are not short of fuel, nor are we short of energy, so there will be enough time to perfect him. Fission-type nuclear power plants are fundamentally different from traditional power plants, so they should be cautious and cautious, and the higher the safety, the better. Wen Deji nodded and said.

"Mr. Wen is right. Although the Gen 3 reactor can also be put into commercial operation, it still has a number of disadvantages, the biggest of which is the problem of spent fuel disposal that you mentioned earlier. Li Tianye's eyes contained reverence.

As a rigorous scientist, although he used to think that Wen Desi was a very outstanding leader, but that's all, he absolutely didn't believe in the "myths and legends" about Wen Zong that were circulated by those new sects and folklore, but since he entered the black technology research department, his three views have been subverted.

When he entered the black technology research department, he could often have close contact with Mr. Wen, which was completely different from the previous contact that could only be done on radio and television. As a leader of a big country, Mr. Wen often takes time to inspect and guide these black technology research departments, and will also communicate with them during the period.

Then Li Tianye was very surprised to find that the "guidance work" written on the original welcome speech was really not a scene. Mr. Wen has amazing attainments in the field of science and technology, and there are many problems encountered in their research, Mr. Wen can point out the key points to the point, and some can also give detailed solutions, at least they can also point out the direction so that they will not take detours. And they can also put forward many things that they didn't think of in advance, such as this "spent fuel disposal problem", which was raised by Mr. Wen at a symposium in the nuclear industry, and they had not thought about it before.

What surprised Li Tianye the most was that Mr. Wen was not only proficient in the nuclear industry, but at his position, he had access to much more confidential information than the people. Then he found that there were countless projects that were "guided" by Mr. Wen, covering various fields including biology, agriculture, machinery, electronics, chemical industry, etc., and all of them were high-tech black technologies.

God, how can there be such a genius in the world? Is there really a saint who comes out once in 500 years? There is indeed that kind of demon in this world that makes people doubt the value of their existence.

Thinking of this, he hurriedly thought that he still had to introduce a job to the boss, and after a pause, he said: "The third-generation reactor is a thermal neutron reactor, or slow neutron reactor, which mainly uses uranium-235 as a fission fuel, and uranium-235 only accounts for 0 of natural uranium. Around 7%. In the case of thermal neutron reactors, burning once can only burn 0 of the nuclear fuel. About 45% and the remaining 99% are spent fuel that cannot be burned, mainly uranium-238. Not only is this extremely wasteful, but the spent fuel is highly radioactive and toxic, making it very cumbersome to deal with. ”
