Diesel-electric submarines use diesel engines on the water surface and batteries underwater. Due to the limited power of the battery, they must float out of the water to ventilate and charge the battery every once in a while.

This is also the most dangerous time for submarines. Many submarines are destroyed under the surface state.

At the suggestion of Cialek, Germany invented a snorkel, which could not be floated out of the water. The diesel engine could be started to charge the diesel engine without having to float out of the water. However, after all, there are also snorkels exposed. During the operation of the diesel engine, black smoke will also appear, floating above the water surface, and it is still easy to be discovered.

So, the best solution is nuclear power!

In later generations, only five rogues owned nuclear submarines, which were their effective tools to protect their own interests.

During the Taiwan Strait crisis, Uncle Sam's aircraft carrier formation approached. As a result, the satellite discovered that the nuclear submarines in China's nuclear submarine base had disappeared. Even though the nuclear submarines were still very noisy at that time, Uncle Sam still withdrew his aircraft carrier by a hundred nautical miles in order to ensure insurance.

In history, nuclear submarines only made breakthroughs in the 1950s, but now, history has been greatly advanced.

The theory about nuclear fission was achieved through leaps and bounds in the 1920s and 1930s. As long as you have enough investment and the correct direction, you can make a breakthrough.

For example, in history, Heisenberg made a mistake and believed that the atomic bomb could not be built, but he mainly attacked nuclear reactors. Before Germany failed, he had conducted many experiments on nuclear reactors.

Now, under the promotion of Cialek, the experiments on nuclear reactors have been carried out earlier.

At the beginning, at the base in Libya, German researchers began to work hard for breakthroughs in nuclear technology. Although their main purpose was to use nuclear reactor combustion to generate nuclear fuel and achieve the goal of manufacturing nuclear bombs, the heat generated by the nuclear reactor was still used by them to generate electricity. The power of the entire base was enough to provide the nuclear reactor.

The nuclear reactors in the Libyan base have been operating safely for seven or eight years. With the investment of Germany, larger reactors are constantly being built. After all, it takes a huge amount to generate a reactor that is sufficient to make nuclear bomb raw materials.

At the same time, nuclear reactors specially used for submarines have also been studied as a special topic.

On land, you don’t have to worry about the volume and weight of the nuclear reactor. Use thick cement concrete as the shell is very safe and can also prevent the emission of rays.

However, on submarines, it must be simplified.

"First Cialek, I'm happy to see you."

When Cirick walked into the boat, just by surprise, he saw a young scientist.

Werner Karl Heisenberg is less than forty years old now, but he is already the most authoritative nuclear technology expert in Germany. Under his leadership, German scientific researchers are overcoming various technical difficulties of nuclear bombs.

At the same time, he also needs to be responsible for the development of nuclear reactors for nuclear submarines. Now, as nuclear submarines are being built, he has even come to the shipyard to carry out some coordination work.

Heisenberg was very excited when he met Cialis. This was not only because Cialis was the head of the empire, but more importantly, he was a technical expert. You should know that everything now comes from a nuclear fission equation, which was proposed by Cialis.

In the construction of nuclear reactors, Cialek has proposed many plans.

"Dr. Heisenberg, thank you for your contribution to the empire." Cirick reached out and shook hands enthusiastically with Heisenberg.

"We have frozen the design drawings," Heisenberg said. "We have built a special simulation reactor on land for the nuclear power system of this submarine. It has been verified that there is no problem at all, but the power is not enough. After calculation, the maximum speed of the submarine will not exceed 15 knots."

After all, it is less than 40 years old. Various industrial technologies are not as developed as later generations. In later generations, all nuclear submarines can reach a high speed of 30 knots.

But, it's not possible now.

Various pipelines cannot withstand too much pressure. When the pressure is high, various problems will arise. At the same time, the power density of the nuclear reactor is also greatly limited. The submarine has been amplified to a displacement of 6,000 tons, and it can only reach a speed of 15 knots.

However, if compared with diesel-electric submarines, it is nothing.

When using batteries underwater, diesel-electric submarines can only have a speed of 17 knots at most, but in this case, precious electricity will be consumed at an astonishing speed, or even an hour.

However, now, this nuclear-powered submarine can run for several months at a speed of 15 knots, which depends entirely on the submarine soldiers' underwater tolerance.

Cialek nodded: "Well, this is just the beginning. We cannot pursue too high technical goals, mainly to ensure good safety issues."

Submarine soldiers are one of the most dangerous types of troops. As long as there is a problem, there will be almost no escapers.

Diesel-electric submarines are no exception. After being attacked, the battery often appears in diesel-electric submarines. When seawater enters the battery, terrible hydrogen will be generated. Then, when the hydrogen explodes in flames, the entire submarine will become fragments underwater, and no one can survive.

The most important thing about nuclear-powered submarines is the problem of nuclear leakage, and rays are very lethal to people.

"Yes, we used a large number of thick lead plates in the nuclear reactor and the first circuit." Heisenberg said: "At the same time, a large number of radiation recorders were also set up on the submarines. Once the radiation exceeds the standard, the alarm will be called immediately."

Using lead plates to block rays is a common method, and of course, this method will also increase the weight of the submarine.

"Nuclear reactors must have safety capabilities, especially after an accident, they must be able to shut down safely and avoid control failure." Cialek continued.

The accident at the nuclear power plant in later generations is still warning humans that when opening Pandora's box, one must have the ability to cover it.

"Yes, what we value most about this nuclear reactor is safety, so it reduces the output power and makes it easier to shut down the reactor." Heisenberg nodded repeatedly.

"The second problem is that the noise of the submarine must be solved well, which is related to the survival of the submarine."
