Doomsday Bunker Upgrade

Although the researchers only answered Chen Xin with a simple sentence, the meaning behind this sentence is the hard work of many people.

In Jianning, another city in Hunan Province not far from Chen Xin's city, workers are busy debugging a brand new train in the factory.

The meteorites fell from the sky, not only bringing the long night of dusty sun, but also destroying the railway power supply lines that originally spread across the country, so that the country can only take out the original old-fashioned coal-fired steam locomotives for reuse, and the original electric locomotives have been destroyed. Most are lying down.

Although there are still some fuel locomotives that can be used, but because of the tight fuel supply, these fuel locomotives that can still move have all been deployed to the most critical places to be responsible for the transportation of the most critical materials.

But in addition, comrades on the railway front have also been trying to find ways to restore railway capacity.

The train they are debugging now is a new car specially researched and developed by Jianning's train factory in order to restore railway capacity.

The train compartment has been specially designed for heat preservation, cold protection, frost resistance and wind resistance, which not only thickens the wall of the compartment, but also increases the stability of the car body.

According to the original design indicators, this new car needs to deal with tenth-level strong winds and low temperatures of minus 50 degrees, but now it is clear that this car needs to face more severe challenges.

The factory workers adjusted and strengthened it, added counterweight to the body, and replaced the thermal insulation material in the compartment wall to ensure that it can still have sufficient thermal insulation effect in the environment of minus 70 degrees.

Because this train is not only used to transport some valuable materials, it is also an attempt by the country to restore personnel transportation.

Before the disaster, Jianning was an important train production base in the Yan Kingdom. The locomotives produced here were also famous in the Yan Kingdom. Even most of the trains running on the important high-speed railway lines in the Yan Kingdom were produced here.

Therefore, for the workers of Jianning Train Factory, they are quite rich in technology and experience.

In fact, before the disaster, they had developed a high-speed train that could still operate normally at a low temperature of more than minus forty degrees. Now they have just optimized the technology.

It was only after the disaster that the railway power supply network all over the country was destroyed, and the electric locomotives lost their power supply and could no longer operate normally.

After all, the curb weight of an ordinary trunk freight locomotive is as high as 240 tons, and the traction power reaches 9600KW. Without a surging power supply, it is impossible to move this behemoth.

Therefore, the focus of the debugging of this new car is actually the power system at the front of the car, not the carriage.

Because it is no longer possible to supply power through the transmission lines, the front of the car must now generate its own power.

This is still very easy to do. Whether it is coal or oil, it can drive a steam turbine to generate electricity, thereby providing enough power for the entire train.

However, this new train built by the workers of the Jianning Train Factory is not powered by an internal combustion engine, but a small nuclear reactor.

This is a nuclear powered locomotive.

The reactor used is the technology of Yan Kingdom itself, which was originally applied to nuclear submarines, but due to technical limitations, the size has not been reduced, and it is impossible to apply it to trains and civilian ships.

Moreover, the tonnage of nuclear submarines ranges from several thousand tons to tens of thousands of tons. The reactor that can drive the nuclear submarine is too powerful for a train. If you want to apply it to the train, in addition to reducing the size, you must further reduce the power. .

However, this is not something that can be done easily. Apart from the nuclear loading part of the reactor itself, the related supporting equipment will occupy a huge space. A compartment is specially designed on the submarine to provide a place for the nuclear reactor to be placed. You can do that on a warship, but obviously not a train, there's not that big of a place.

However, Chen Xin's isotope thermoelectric battery has given researchers a lot of inspiration and technical support, allowing them to successfully miniaturize the reactor on the original nuclear submarine again, and improve the related technology, to successfully create a train that can be installed on the train. small nuclear reactors.

This reactor is not a traditional light water reactor, but a thermoelectric conversion type similar to an isotope thermoelectric battery, which directly converts thermal energy into electricity.

The advantages of doing so are naturally many. The radioactive core can be completely sealed to prevent radiation leakage, because it only needs to conduct heat and convert it into electricity, and it is not necessary to inject cooling water into the reactor to boil the water to drive the steam turbine to generate electricity. In terms of efficiency, the former is naturally more efficient.

With such a small nuclear reactor, it is very easy to drive a train, even if the traction power of a passenger train is more than 5600KW.

Because a general small nuclear reactor refers to a reactor with an output power of less than 300MW, 1MW is 1000KW, and if you want to drive a train, only 10~15MW of power is enough.

The output power of the small reactor currently installed on this new train is 35MW. In addition to driving the train itself, it can also provide abundant power for the body for heating, lighting and a series of electricity needs, including de-icing. and clearance.

The project was set up and researched three months before the meteorite fell, and the manufacture of the car body began at that time.

The progress of other parts is very fast, the only limitation is the power system, which was not lifted until Chen Xin provided isotope thermoelectric batteries to the country, and this new train finally successfully walked off the production line and is about to be put into operation. is running.

The first task of this new nuclear-powered train is to deliver production equipment to the city where Chen Xin is located.

It is also the special train mentioned in what the researchers told Chen Xin.

Its successful operation is not only the improvement of railway transportation conditions and the enhancement of transportation capacity, but also a more convenient and safe way to apply nuclear power.

The power generation of the small nuclear reactor used on the train is enough to supply all the electricity of a small county before the disaster. In this case, if a city can have a small nuclear reactor, the electricity consumption of the whole city will be reduced. Don't worry at all, you can even convert the heating method into electric heating.

The reason why Yan Guo did not do this before was because there were too many technical problems that could not be solved, and it was too late to temporarily build a new nuclear power plant, so he did not use this method to power the shelter before the disaster.

But now that there is a safe and reliable small nuclear reactor technology, the top executives of the Yan Kingdom will obviously not let go of such clean, efficient and convenient energy.

I have been back to my hometown from Hunan in the past two days, and I have been traveling all the way. The update is very affected, but it is already being adjusted today. It will be four changes tomorrow, and then three times a day will resume.
