Chapter 1432

"On the whole, it has reached the advanced level in our plan, but we still have a big gap compared with the submarines of other countries in the world," Huang said when he came out again.

So far, the total number of nuclear submarines in China is only a few, while bear country and Eagle country are dozens of submarines making dumplings together.

Electronic systems can catch up, but there is still a big gap in other aspects, such as nuclear reactors.

The reactor of our own nuclear submarine needs to be refueled every seven years. Each replacement is a big project. It may also cause radioactive pollution. What about the west? The core life has exceeded 20 years, and some even have the same life as nuclear submarines, so there is no need to replace nuclear fuel.

Besides power, the reactor of our nuclear submarine has a power of 90 MW. Driving this 8000 ton nuclear submarine can only reach the maximum speed of 22 knots. It can be said that it is to solve the problem of whether there is a problem or not.

What about the west? The most famous Ohio class has a power of 250 MW and a speed of 30 knots, which is the gap brought by the huge industrial foundation.

Nuclear power system is a big problem. In later generations, Jiguo directly transplanted the reactor of their nuclear submarine to the nuclear powered aircraft carrier. It was found that the power was insufficient and the maximum speed could not reach the design goal.

These problems need to be solved.

"By the way, are there any land piles here?" Qin Guan asked old Huang.

In the study of nuclear submarines, the key is to study nuclear reactors, which can not be put on submarines at once. Before getting on submarines, we must go through the study of land nuclear reactors.

Qin Guan wants to exchange systems. If he doesn't intend to exchange his valuable nuclear submarines directly for nuclear submarines, he must find enough raw materials. The tens of thousands of tons of steel has been a headache for Qin Guan. The last time he salvaged the sunken ship and exchanged nitka, he can't do it again this time. Where are so many sunken ships to look for.

Besides steel, there are nuclear reactors. This is the most important.

It would be great if there were a land pile.

"In 9909 base," said Huang, "if you are interested, Mr. Qin, I can take you."

That's too far. Although their super power can start the exchange from a long distance, it is absolutely impossible to exchange the land pile there across half a country.

When the guide started the exchange from a long distance, Qin Guan suddenly thought of something. Except for the nuclear reactor, he seemed to have found a solution to other problems.

This is a shipyard. Steel is everywhere. There are trains directly to this place. When steel is transported, it is often thousands of tons.

Just start the exchange directly and get the steel. Even the train can throw it in when needed. Anyway, it's not as expensive as a submarine.

There is only the problem of nuclear reactors. As long as this problem is solved, everything else will be easy to do.

"Do we have here?" Qin Guan asked.

"It can also be said that there are." old Huang said to Qin Guan, "before construction, our nuclear submarines need to assemble nuclear reactors on land. After passing the test, they can be put on the submarine and hoisted as a whole."

The nuclear reactor is hoisted as a whole, just like the hoisting of the whole East-West system. When getting on the submarine, this thing must be wrapped layer by layer without any accident. Huang pointed to a place guarded by heavy troops not far away and said, "there is the next set of nuclear power system we are assembling."

The construction of nuclear submarines is long. As the core component of nuclear submarines, shipyards also have special workshops to assemble nuclear reactors. Now, the construction of Type 091 nuclear submarines is still ongoing, and the construction of the second Xia class ballistic missile has also begun.

There is, that's good.

Captain Xu on one side has frowned. If Qin Guan says he wants to visit there, should he dissuade him? How should he dissuade him?

Captain Xu had some contradictions. Fortunately, Qin Guan didn't ask for a visit there. He said, "where's the canteen? I'm so hungry. I heard your food is good."

The food of the submarine soldiers is good. They go on submarines to perform their tasks. Here, they are all on land. The food is almost the same as usual. However, Qin Guan's practice is admired by many people. He never puts on a high airs and goes to any place for investigation. He always likes to work with grass-roots personnel.

Here belongs to the finished product area. In the distance, Mars is still splashing on the platform of the shipyard. The workers are still working hard and contributing their youth to the motherland.

Qin Guan came to the canteen to eat like ordinary people, and his scholars have been sent out by him to coordinate and contact. "Braised meat is good." Qin Guan looked at the food in his lunch box with a happy face. The person in charge of such a big company would not be complacent about a meal of braised meat, would he?

"Mr. Qin, what do you think of our nuclear submarine industry?" old Huang and captain Xu were eating with Qin Guan. Watching Qin Guan eat ordinary canteen food, they all felt a little more cordial. Old Huang couldn't help asking.

Qin Guan has made many suggestions to the ballistic missile industry before. Even Qin Guan has helped provide ballistic missile launch vehicles and promised to sponsor them. However, Qin Guanke has never said anything in the field of nuclear submarines.

Now, hearing Huang Lao's question, Qin Guan swallowed the braised meat and said, "for nuclear submarines, the first element of survival is silence."

Qin Guan is right. Nuclear submarines can be slower and lower in depth. However, they must be silent. If the mute performance does not meet the standard, it is a dead end and has no practical significance. If it reaches the same level as the ocean background noise, it is an ocean black hole, and you can do whatever you want in the ocean.

"Among them, the most important thing is the nuclear reactor. It is the most important work to improve the self circulation capacity of the nuclear reactor and reduce its noise. We also look forward to the efforts of our comrades in the nuclear power system."

Nuclear reactors need to circulate, and there is an important primary water pump, which is the main source of noise. Domestic submarines need this water pump to be turned on as long as the nuclear reactor is started, while foreign advanced systems can circulate by themselves at low speed. At this time, there is no need to turn on the circulating water pump, which has unparalleled silence, For example, the most famous sea wolf class in the eagle kingdom of later generations ran to section 18, and people's water pumps still didn't need to be turned on, but they were still silent.

Old Huang nodded. Now, we can only use all kinds of seismic means to suppress it. It's the stupidest way.

"In a few days, we will get an advanced ship from the special front, which can be used as a reference for everyone to study." Qin Guan said with a smile.

In this era, if we can get a nuclear submarine directly, it is definitely a joke. Old Huang also laughed twice. President Qin can really joke.

They don't know. When this evening passes and tomorrow morning, they will know that President Qin will never joke. Everything president Qin said will become a reality.

Just a nuclear submarine, little fun.
