Doomsday Bunker Upgrade Chapter 307: Nuclear Power Train

Although the researchers answered Chen Xin with only one simple sentence, what is 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.

Meteorite falling from the sky not only brought a long night of dust and sun, but also destroyed the railway power supply lines that were originally all over the country, so that the country could only take out the original old-fashioned coal-fired steam locomotive and use it again, while the original electricity Most of the locomotives are already lying down.

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

But apart from that, comrades on the railway front have also been thinking of ways to restore railway capacity.

The train they are currently debugging is a new train 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.

Workers at the factory adjusted and reinforced it, added counterweight to the body, and replaced the insulation material in the cabin wall to ensure that it can still have enough insulation in an environment of minus 70 degrees. Effect.

Because this train is not only used to transport some valuable materials, but 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 at 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.

Just after the disaster, 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. The original advanced electric locomotives were all lying down. Can not operate.

After all, the curb weight of an ordinary mainline 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.

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

Because it is no longer possible to supply electricity through the transmission line, it is now necessary to let the front of the car itself generate power.

This is still very good. 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 workers at 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 Yan Kingdom's own technology. It 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.

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

However, this is not something that can be done easily. Except for 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 this on a large 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 energy A small nuclear reactor mounted on a train.

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 electrical energy.

There are many advantages of doing this. The radioactive core can be completely sealed to prevent radiation leakage, because it only needs to conduct heat and convert it into electricity, instead of injecting cooling water into the reactor to boil the water to drive the steam turbine to generate electricity. In terms of energy conversion 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 the general small nuclear reactor refers to a reactor with an output power of less than 300MW, 1MW is 1000KW, 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 a series of electricity needs such as heating and lighting. Come to deicing and clearing obstacles.

This project was initiated 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~IndoMTL.com~ This restriction was not lifted until Chen Xin provided isotope thermoelectric batteries to the country, and this new train finally succeeded. Off the production line, it is about to be put into operation.

The first task of this new nuclear-powered train is to transport 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 increase of capacity, but also a more convenient and safe way for nuclear power applications.

The power generation of the small nuclear reactor used on the train is enough to supply all the electricity used by a small county before the disaster. In this case, if a city can have a small nuclear reactor, the whole city's electricity You don't have to worry about using electricity at all, and 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 to solve, and it was too late to build a new nuclear power plant temporarily, so this method was not used to power the shelter before the disaster.

But now that there is a safe and reliable small nuclear reactor technology, it is obvious that the senior officials of Yanguo will not let go of such clean, efficient and convenient energy.
