Yu-2 is scheduled to serve in 1966. If the development process is overturned and the service time node is delayed, it will be very embarrassing-this may mean that when the first domestic nuclear submarine is delivered to the Navy, it can only use unguided direct torpedoes .

The situation on the nuclear submarine side is as follows:

The Ship Design Institute split out a nuclear power team headed by Peng Shilu. This group of young people lived in the Lanzhou Nuclear Power Institute of the Institute of Atomic Energy and did not move for two years.The Institute of Atomic Energy's support for the Navy's nuclear power program is also very high. Despite Tang Hua's repeated "interference" to improve the technical parameters and standard requirements of the nuclear submarine reactor, the design of the land-based simulation reactor of the nuclear submarine reactor has still been completed and is now under construction. , if it is soon, it will be completed and started in 1962.

这个反应堆是压水堆，采用20%的中等浓度浓缩铀，输出功率……大概能让5000多吨的潜艇在水下跑出30节的航速，或者让8000~10000吨的潜艇跑出20多节的航速。

According to the process of the nuclear submarine project, when the land simulation reactor starts normally, the keel of the first nuclear submarine will be laid in Wuhan; after the land simulation reactor completes long-term operation and 24-hour full-power operation test, the first nuclear submarine will install the reactor.

If the nuclear submarine simulation reactor was completed and operated in 1962, it would not have been a few years since the nuclear submarine came out.

……

Lanzhou.

The provincial capital of Gansu Province, once the main transportation hub of the Silk Road, is now one of the most important industrial cities in Northwest China. , tritium, reactor.

In 1960, "梼杌" was tested and exploded. Tang Hua passed by Lanzhou when he was going to Xinjiang, but he didn't get off the car.This is the first time to stay in Lanzhou.

"I heard that you haven't been out of Lanzhou for two years from 59 to now?"

At the Lanzhou Institute of Atomic Energy, Chinese Academy of Sciences, Tang Hua met Peng Shilu.

Peng Shilu's father is Peng Pai, and his parents were gone when he was four years old. Wherever he goes, he is home. After two years in Lanzhou, he has no concept of going home for the New Year, but he doesn't even go out of Lanzhou, which is too nerdy.

"Minister Tang, to be honest, there are really not many places worth visiting in Gansu, so I omitted it. The Lanzhou Institute of the Institute of Atomic Energy is very good, and the courtyard is big enough to stay there."

Peng Shilu is from Shanwei, Guangdong. In his opinion, the Northwest Gobi is too dry and monotonous. There are not many places to visit in Lanzhou and the suburbs of Lanzhou.

Tang Hua: "Has Martha been transferred?"

"I've been transferred, and I'm also working in our courtyard in Lanzhou."

Tang Hua leaned over and said to Peng Shilu in a low voice: "Bold Peng, it's okay for you to work hard, but you shouldn't say that she is the third in front of your wife. At least you have to say that she is the second."

……

It goes like this:

One weekend morning, after getting up, Peng Shilu was in a daze on the bed. His wife asked him what he was thinking, and he said, "I'm thinking about my first lady."

Martha said, "Me?"

Peng Shilu said: "No, my first lady is a nuclear submarine."

Martha: "Okay, I'll let this one go. I'm the second lady, right?"

Peng Shilu: "The second lady is smoke."

……

Tang Hua: "To be honest, what happened after you said that the second lady is Yan?"

"Nothing happened, I just washed clothes for a week."

Chapter 48, Naval Nuclear Power Office

Of course, Tang Hua didn't come to Lanzhou to eat beef noodles.On the same day as arriving in Lanzhou, a special train from the Heavy Machinery Bureau of the Ministry of Heavy Industry transported the equipment to the Lanzhou Research Institute of the Institute of Atomic Energy.

"I have seen the design drawing of your land-based simulation reactor building," Tang Hua said. "Of course, the size of the reactor strictly complies with the size specified in the overall design of the submarine, and the factory building has also been made like a submarine. However, your previous vibration and pitching and rolling The simulation is too simple. Now, it is up to the Bureau of Heavy Machinery to add some materials to the building of your land simulation reactor."

……

When Hyman Rickover, the "father of American nuclear submarines", determined the design of the nuclear submarine reactor, he insisted on conducting anti-high heat and anti-vibration tests on every component of the reactor, and then doing anti-vibration tests on the reactor subsystems. Components and subsystems that pass the test are returned for re-improvement.

In addition, Rickover also pioneered the construction process of nuclear submarine reactors: build two identical reactors, one is a land-based simulation reactor, and the other is a reactor that is actually installed on a boat. After the node, the reactor on the boat followed the test of this node.

As the world's first nuclear submarine, the "Nautilus" power system worked unexpectedly stable after delivery, which has a lot to do with the process formulated by Rickover.

The design and construction ideas of the land-based simulation reactor have long been copied from the nuclear submarine project.Now, it's time to copy the severe operating condition test system of the reactor.

The young expert in front of the wife, Peng Bold in the reactor design team, and Peng Shilu, a descendant of Peng Peng, felt a little dizzy looking at the completely rebuilt mock reactor plant with the top cover removed.

The first thing to be installed in the mock reactor building is the inclined platform under the floor, with a carrying capacity of 16 tons, supported by [-] giant hydraulic columns. The hydraulic columns are in groups of four and can be raised or lowered according to instructions. Going up the simulation pile, there will be left leaning, right leaning, forward leaning, backward leaning and other postures in turn.

A nuclear submarine will tilt forward and backward when it dives or floats rapidly; it will tilt left and right when there are big waves on the water surface or when it makes a sharp turn underwater; if it is damaged in battle, the tilt will be more serious.

The reactors of nuclear submarines have to work normally in all kinds of strange and inclined environments, and output high-temperature and high-pressure water vapor to propel the submarine forward.

There is a vibration mechanism on the variable tilt platform, which is not only a tilt platform, but also a vibration test platform.There could even be a joint test—making the reactor work both tilted and violently shaken at the same time.

Huang Shilong: "That's it, the simulation pile is ready to be reworked and rebuilt 10 times."

Peng Shilu: "Don't be so pessimistic. I think it will be almost done after 4 or 5 reworks."

Huang Shilong: "Think about how many crazy solutions you have crammed into the reactor design. In order to improve performance, you can do everything you can."

Peng Shilu: "The new designs are all calculated and demonstrated repeatedly. How can it be so easy to make mistakes... Even if they are wrong, they should not be wrong everywhere."

……

"Now the nuclear submarine project team is divided into the Wuhan branch and the Lanzhou branch. One is engaged in the overall nuclear submarine, and the other is engaged in the nuclear power system. Both branches are very busy, so I won't call you together for a meeting."

Tang Hua briefly announced the decision on the nuclear submarine project.

"The National Institute of Advanced Technology is going to establish a naval nuclear power research office, which will be officially established in September this year. This is the fourth office established by the National Institute of Advanced Technology. In the future, you will cooperate with strategic missiles, atomic bombs, satellites and spaceflight It is classified as a research unit of major military and high-tech equipment.”

"The director of the office is Yu Xiaohong, Lao Yu."

Yu Xiaohong: "There are still three months before the official establishment. Minister Tang, can you discuss with Nie Shuai that you don't want me to be the director. I have been fighting for most of my life and have never studied in university. Peng Shilu, Huang Xuhua, Xia Tong, Qian Lingbai, you two are very powerful, come out and stand on top of each other."

Peng Shilu and Xia Tong: "No."

Tang Hua: "If Huang Xuhua and Qian Lingbai knew about it in Wuhan, they would definitely say 'no'. Old Yu, don't refuse. The central government has already decided that you will be the director, in charge of the development of nuclear submarines and team coordination. "

There are four offices under the National Defense Advanced Technology Research Institute. The director of rockets and missiles is Qian Xuesen, the director of nuclear weapons is Qian Sanqiang, and the director of satellites and spacecraft is Tang Hua. The group is headed by the group.

It's no wonder that Yu Xiaohong is so nervous that she's sweating profusely now.

During the Anti-Japanese War, Lao Yu first served as the head of the Independent Regiment of the New 129th Brigade of the 8th Division, and later served as the commander of the Weihe Detachment. The detachment has more than 1 people, the soldiers are strong and the discipline is strict, which is not 01:30 better than Li Yunlong's independent regiment.

Lao Yu can not only fight devils, but also remotely build and operate bases. This kind of leadership ability will definitely be very useful in the nuclear submarine project.

Tang Hua: "Grasp the general direction of development at the macro level, and carry forward the spirit of democracy in specific work. The three cobblers will definitely be able to stand up to Zhuge Liang. Lao Yu, just roll up your sleeves and do it."

Yu Xiaohong: "Hey, I have a hard heart all my life, forgetting my family and wanting to serve the country, so let's do it, at worst, I will fall on the road of attack, and I will die a well-deserved death."

"This office is called the 'Navy Nuclear Power Office' instead of the 'Nuclear Submarine Office'. Can you explain your understanding?"
