Chapter 879: Nuclear powered submarine

Diesel-electric submarines use diesel engines on the surface of the water and batteries underwater. Due to the limited power of the batteries, they must be exposed to the surface for ventilation and recharge the batteries at regular intervals.
This is also the most dangerous time for submarines. Many submarines are destroyed on the surface.
Under Cyrenk’s proposal, Germany invented the vent pipe, which can start the diesel engine for charging without being exposed to the surface. The black smoke comes out, floating above the water, and it is still easy to be found.
Therefore, the best solution is nuclear power!
In later generations, only the five big gangsters have nuclear submarines, which are powerful tools for them to defend their own interests.
During the Taiwan Strait crisis, Uncle Sam’s aircraft carrier formation approached. As a result, the satellite discovered that all the nuclear submarines in China’s nuclear submarine base had disappeared. Retreated his aircraft carrier one hundred nautical miles.
In history, nuclear submarines only achieved a breakthrough in the 1950s, but now, history has been greatly advanced.
The theory of nuclear fission was developed by leaps and bounds in the 1920s and 1930s. As long as there is sufficient investment and the right direction, a breakthrough can be achieved.
For example, in history, Heisenberg made a mistake, believing that an atomic bomb could not be built, and as a result, attacked nuclear reactors. Before Germany failed, he had conducted many nuclear reactor experiments.
And now, under Cyric's promotion, experiments on nuclear reactors have been carried out earlier.
At the beginning, at the base in Libya, German scientific researchers began to work hard for the breakthrough of 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 nuclear reactors , It is still used by them to generate electricity. The entire base’s electricity is sufficient if it is provided by the nuclear reactor.
The nuclear reactors in the Libya base have been operating safely for seven or eight years. With the investment of Germany, larger reactors have been continuously built. After all, a huge amount of reactors are needed to generate enough materials for nuclear bombs.
At the same time, nuclear reactors dedicated to submarines have also been studied as a special subject.
On land, there is no need to worry about the volume and weight of nuclear reactors. Thick cement concrete is used as the outer shell, which is very safe and can also prevent the emission of rays.
However, on the submarine, it must be simplified.
"Head Cyric, it's nice to meet you."
When Cyric walked into this slipway, not surprisingly, 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 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 has come to the shipyard to carry out some coordination work.
Heisenberg was very excited to see Cyric. This is not only because Cyric is 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 put forward many plans.
"Dr. Heisenberg, thank you for your contribution to the empire." Cyric reached out and shook hands enthusiastically with Heisenberg.
"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. After verification, there is no problem at all, but the power is not enough. After calculations , The maximum speed of the submarine will not exceed 15 knots."
After all, it is less than 40 years, and various industrial technologies are not as developed as later generations. In later generations, all nuclear submarines can reach a high speed of 30 knots.
However, 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 nuclear reactors is also very limited. The submarine has been enlarged to a displacement of 6,000 tons. The speed is only 15 knots.
However, if compared with diesel-electric submarines, it is nothing.
Diesel-electric submarines have a maximum speed of 17 knots when using batteries underwater. However, in this case, the precious electricity will be consumed at an alarming rate, and even one hour can be used up.
But now, this nuclear-powered submarine can run for several months at a speed of 15 knots, depending on the submarine's underwater endurance.
Cyric nodded: "Well, this is just the beginning. We can't pursue too high technical goals. The main thing is to ensure safety."
Submarine soldiers are one of the most dangerous arms. As long as there is a problem, there are almost no survivors.
Diesel-electric submarines are no exception. After being attacked, the batteries of diesel-electric submarines are often damaged. When sea water enters the batteries, terrible hydrogen is generated. Then, when the hydrogen encounters an open flame, the entire submarine is underwater. Broken into pieces, no one can survive.
As for nuclear-powered submarines, the most critical issue is nuclear leakage. Rays are very lethal to people.
"Yes~EbookFREE.me~ We use a lot of thick lead plates in the nuclear reactor and the primary circuit." Heisenberg said: "At the same time, a large number of radiation recorders are also installed on the submarine. If the radiation exceeds the standard, the police will be called immediately."
Using lead plates to block the rays is a common method. 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 without control failure." Cyric continued.
The nuclear power plant accidents in later generations are still warning human beings. Once the Pandora's box is opened, it must be able to cover it.
"Yes, for this nuclear reactor, our most important thing is safety, so the output power is reduced and shutdown is easier." Heisenberg nodded repeatedly.
"The second problem is the noise of the submarine. It must be resolved. This is related to the survival of the submarine."
Cyric is very clear that the magic weapon for submarines to survive underwater is to be silent. Only when they become oceanic black holes can they make silent attacks. The lower the noise, the better the concealment.
