#881 Nuclear Powered Submarine (Plus More)

Diesel-electric submarines use diesel engines on the surface and batteries underwater. Due to the limited power of the batteries, it is necessary to surface for ventilation and recharge the batteries every once in a while.

This is also the most dangerous time for submarines, and many submarines are destroyed in the surface state.

Under the suggestion of Cyric, Germany invented the snorkel, which can start the diesel engine for charging without surfacing the water. Black smoke came out and floated above the water, and it was still easy to be found.

So, the best solution is nuclear power!

In later generations, only the five rogues have nuclear submarines, which are a powerful tool for them to safeguard their own interests.

During the Taiwan Strait crisis, Uncle Sam's aircraft carrier formation approached. As a result, the satellite found that the nuclear submarines in Huaxia's nuclear submarine base had disappeared, even if the nuclear submarines at that time were still noisy Han-class, Uncle Sam was still safe for insurance. He pulled his aircraft carrier back a hundred nautical miles.

Historically, the breakthrough of nuclear submarines was only achieved in the 1950s, but now, history has been greatly advanced.

The theory of nuclear fission has advanced by leaps and bounds in the 1920s and 1930s. As long as there is enough investment and the right direction, a breakthrough can be achieved.

For example, in history, Heisenberg made the mistake of thinking that the atomic bomb could not be built, and as a result, he mainly attacked the nuclear reactor. Before the failure of Germany, he had already conducted many experiments on nuclear reactors.

And now, under the impetus of Cyric, experiments on nuclear reactors were carried out earlier.

At the beginning, in 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 making nuclear bombs, the heat generated by nuclear reactors , or be used by them to generate electricity, the power of the entire base, it is enough to have a nuclear reactor.

The nuclear reactors in the Libyan base have been operating safely for seven or eight years. With the input of Germany, larger reactors are being built continuously. After all, it requires a huge amount of reactors to generate enough raw materials for nuclear bombs.

At the same time, nuclear reactors for submarines were also studied as a special subject.

On land, there is no need to worry about the size and weight of the nuclear reactor. Thick cement concrete is used as the outer shell, which is very safe and can also prevent the emission of rays.

On submarines, however, it has to be simplified.

"Führer Cyric, it's a pleasure to meet you."

When Cyric walked into the slipway, it was no accident that he saw a young scientist.

Werner Karl Heisenberg is not yet forty years old, but he is already the most authoritative nuclear technology expert in Germany. Under his leadership, German researchers are conquering various technologies of nuclear bombs. Difficulty.

At the same time, he also needs to be responsible for the development of the nuclear reactor of the nuclear submarine. Now, while the nuclear submarine is under construction, he even came to the shipyard to carry out some coordination work.

Heisenberg was very excited to see Cyric, not only because Cyric was the head of the empire, but also a technical expert. You must know that everything now comes from a nuclear fission Equation, and this equation was proposed by Cyric.

In the construction of nuclear reactors, Cyric has proposed a lot of schemes.

"Dr. Heisenberg, thank you for your contribution to the Empire." Cyric stretched out his hand and shook hands with Heisenberg warmly.

"We have frozen the design drawings." Heisenberg said: "For the nuclear power system of this submarine, we have built a special simulation reactor on land. It has been verified and 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 ago. Various industrial technologies are not as developed as later generations. In later generations, various nuclear submarines can reach a high speed of 30 knots.

But not now.

Various pipelines cannot withstand too much pressure. After the pressure is high, various problems will occur. At the same time, the power density of the nuclear reactor is also very limited. The displacement of the submarine has been enlarged to 6,000 tons. 15 knots only.

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

Diesel-electric submarines, when using batteries underwater, can only travel at a maximum speed of 17 knots, but in this case, the precious electricity will be consumed at an alarming rate, even in an hour, it can be exhausted.

But now, this nuclear-powered submarine can run for several months at a speed of 15 knots, which depends entirely on the underwater endurance of the submariners.

Cyric nodded: "Well, this is just the beginning, we can't pursue too high technical goals, the main thing is to ensure safety."

Submarines are one of the most dangerous types of arms. As long as there is a problem, there are almost no survivors.

Diesel-electric submarines are no exception. After being attacked, diesel-electric submarines often suffer from battery damage. When seawater enters the battery, terrible hydrogen will be generated. Then, the hydrogen will explode when encountering an open flame, and the entire submarine will be underwater. Broken to pieces, no one survived.

For nuclear-powered submarines, the most critical issue is the issue of nuclear leakage. The lethality of rays to people is very large.

"Yes, we use a lot of thick stereotypes in the nuclear reactor and the primary circuit." Heisenberg said: "At the same time, we also set up a large number of radiation recorders on the submarine. Once the radiation exceeds the standard, it will immediately alarm. ."

Blocking the rays with lead plates is a common method, but of course, this method also increases the weight of the submarine.

"Nuclear reactors must have safety capabilities, especially after an accident, to be able to shut down safely without control failures," Cyric continued.

Accidents at nuclear power plants in later generations are still warning humans. Once a Pandora's box is opened, it is necessary to have the ability to cover it.

"Yes, for this nuclear reactor, our top priority is safety, so the output power is reduced to make it easier to shut down." Heisenberg nodded again and again.

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

Cyric is very clear that the magic weapon for submarines to survive underwater is silence. Only when they become a black hole in the ocean can they make silent attacks. The lower the noise, the better the concealment.
