The biggest difficulty of the uranium bomb route is electricity, although Hu Weidong decided early on to adopt the gas centrifugal method that can greatly save electricity and has introduced this jishu before the Anti-Japanese War, but the purification efficiency of the gas centrifugal method will decline rapidly with the increase of uranium-235 concentration, and its power-saving effect will become less and less obvious, when the uranium-235 concentration is very high, the efficiency will be even lower than the gaseous diffusion method that consumes electricity, not to mention that it is only during World War II, and the level of science and technology is far worse than that of later generations. It is even more impossible to purify weapons-grade uranium with a concentration of more than 90% by gas centrifugation alone.

Therefore, Hu Weidong's choice of method is to first use gas centrifugation to purify uranium-235 concentration of more than 80% of highly enriched uranium, and then change to gas diffusion method to further purify uranium-235 concentration of more than 90% of weapons-grade uranium, which is much more energy-efficient than the gas diffusion method used in Manhattan, the United States, but the power consumption is still quite amazing, and the current annual power generation in China is far from being compared with the United States, so the burden is still very large, Hu Weidong expects that the "911 Project" may consume 20 billion kilowatt-hours of electricity at most a year, It is equivalent to 1/4 of China's total annual power generation in 1942

Under these circumstances, the advantages of the Jihua economic system were once again revealed, and when the whole country made way for the "911 Project", Hu Weidong never worried about the lack of electricity. In addition, the nationwide energy-saving campaign and the DPRK's support (Note 1) have also contributed to the fact that the industrial system is incomplete and the domestic market is very small. As for the Soviet Union, because the efficiency of long-distance power transmission on the current shijie is far from being comparable with that of later generations, the power transmission from North Korea to the European part of the Soviet Union, thousands of miles away, will be consumed so that the Mao Zi, who has always been lavish, can not bear it, and the Soviet Far East, which is relatively close, has no shortage of electricity, so there is no other way out for North Korea's excess electricity except to sell it to China

Originally, the design of the bomb type of the implosion method was also a difficult point, but because Hu Weidong, who led the "911 Project", had participated in the design of the bomb type of the nuclear bomb before. The wife is an expert in this area. So I already knew in my heart that this difficulty had become much easier, and it was not even as good as solving the problem of bathwater for the female comrades in the base, which gave Hu Weidong a headache

In addition to missiles and nuclear weapons, jet aircraft are also a scientific research project that Hu Weidong attaches great importance to. Although well aware of Sukhoi's exceptional talents. However, considering the possibility of Sino-Soviet relations in the future. In order to avoid the development progress of jet aircraft being affected, Hu Weidong still directly took out the design drawings of the J-5 in history. However, the somewhat advanced design also put forward higher requirements for the engine, which led to the repeated postponement of the first flight of China's first jet aircraft. This caused a lot of pressure on Wu Zhonghua, who was entrusted with important tasks at a young age.

Fortunately, Wu Zhonghua has made a breakthrough in the research of gas turbines, a by-product of jet engines, and it is expected to be put into practical application within a year, which has given Wu Zhonghua some comfort to his anxious feelings. Although in the short term, it is difficult for China's gas turbines to make larger models, but it still has greater significance for small weapons such as speedboats. More importantly, gas turbines and helicopters are a perfect match, and its appearance means that helicopters will also get rid of the "flashy" hat and become the new secret weapon of the PLA

However, the by-product is only a by-product after all, and the stagnation of Wu Zhonghua's research on the main item still caused a lot of criticism. In particular, although he is not very old, he has been infected with the kind of stinky temper of many old intellectuals, and when facing the workers, he always feels that he is superior to others, and he will not talk about being arrogant, and there are young workers who are eager to learn and progress to ask for advice, and he rarely cares, and when he is in a bad mood, he will even make ridicule, and as a result, he has offended many people, and countless "letters from the people" have even alarmed Taizu who is far away in Luoyang

Taizu hates the old intellectuals the most is that they despise manual labor and look down on the lower classes, Wu Zhonghua can be regarded as a new intellectual cultivated after liberation to a certain extent, and it is actually this virtue, which makes the great man deeply worried, in order to educate Wu Zhonghua, but also to sound the alarm for other intellectuals, he directly asked Hu Weidong to send Wu Zhonghua down to receive a round of "re-education of poor middle peasants"

Hu Weidong was anxious as soon as he heard this, because at present there is a serious shortage of scientific research personnel in China, and jet engines are an extremely cutting-edge field, and it is not easy to have a competent Wu Zhonghua, and if he is delegated to China now, and there is no one who has the ability to take over in a short period of time, then there is a danger that the research work that has already made a lot of progress will be wasted. Besides, Wu Zhonghua has this temperament in history, and he suffered a lot for this in the first 30 years but still died unrepentantly, so even if he is allowed to accept the "re-education of poor middle peasants", it is just useless work, even if Wu Zhonghua does not hold grudges, he has to delay the development of jet aircraft, but he still has to rely on him when he goes to Zuihou, why bother?

Therefore, Hu Weidong ignored the ban specially issued by the central government for his safety, flew directly from the base to Luoyang to see the chairman, and finally saved Wu Zhonghua after trying his best to talk about it. However, one of Taizu's views was also accepted by him, "The success or failure of a project depends entirely on one person, which is very unreliable, and whenever possible, each study must have at least two sets of people to be prepared." And Hu Weidong felt that this could also form competition and avoid the formation of academic monopoly by scientific researchers, especially those experts, which is of great significance to the long-term and healthy development of China's science and technology.

Although the matter was finally resolved satisfactorily, Hu Weidong still couldn't help but sigh in his heart: on the one hand, intellectuals really had to integrate with the workers and peasants, and on the other hand, they had to rely on them now, and it was difficult to be strict with them, especially many of these guys were very squeamish, and they would take poison and hang themselves if they were wronged, and they had a headache!

"If only China had so many scientific and technological personnel in the future generations, the competition is fierce, and the arrogance will naturally not be able to get up", Hu Weidong, who once again exclaimed, unconsciously remembered the little guy who he wanted to train as a scientist but ultimately failed, "That stinky boy, weishenme can't let go, the motherland needs him!" ”

Note 1: Of the colonies that Japan occupied at the beginning, North Korea had the most developed industry (followed by Taiwan, Northeast Korea, and South Korea). The annual power generation capacity was as high as 5 or 6 billion kWh, much more than the whole of China, including Northeast China at that time, and the fact that North Korea was able to sweep the south in the early days of the Korean War had a lot to do with its strong industrial strength.
