I! Pretending to Be Reborn, Director of Doomsday Hoax

In addition to this, the application of nuclear energy is more mature in the field of aerospace, especially nuclear powered rocket engines, which have long been commonly used in special rocket engines.

The chief engineer of the Berry Country Peanut Town National Railway stroked his beard and said, "Since we want to build nuclear iron in the Berry Country, we should keep our feet on the ground."

"At present, nuclear power plants are used in trains, trains, etc., and there are still several problems that need to be solved."

"The first is the size and load constraints."

"Externally heated closed loops, as well as radiation shielding, cores, etc., would rapidly increase the mass and volume of the train."

"However, whether it is a train, a subway, or a high-speed rail, there are great restrictions on the overall size and single-axle load!"

"Therefore, we must either miniaturize these key components in a short period of time, or redesign the structure of the train and the rails." Everyone was thinking, neither of these two solutions was easy.

"The second issue is cost."

The chief engineer of the Peanuttown National Railway looked worried, and continued: "Rail transportation is characterized by low cost. However, after the thermal locomotive uses nuclear energy devices, although it can increase the cruising range, it loses the remarkable feature of low transportation cost. "

"The cost and technical content of the nuclear power plant are too high, and funds and routine maintenance are required in the later stage, which is also extremely expensive."

Yoder waved his hand and said, "Don't worry about the cost."

"At that time, nuclear iron will become the most important means of transportation in the territory of Berry Country, and it is completely possible to increase the price and subsidize the cost."

When the era of extreme cold comes, cars will definitely be banned.

A large number of railways may also be demolished.

Berry National Nuclear Railway will become one of the few means of transportation. If you want to leave the local area, you have no choice but this means of transportation.

Anything, as long as it has a monopoly and is just needed, no matter how much it costs, it can make a lot of money.

The Chief Engineer nodded to Commander Yod, and continued:

"The most serious issue is safety!"

"According to what the Commander-in-Chief said, I speculate that the Berry Country's nuclear iron will be connected to various state capitals, almost covering the entire inside of the Berry Country's fortress."

"These places must also be densely populated areas. Once a nuclear 'leakage' occurs, it will cause a large area of ​​nuclear pollution, which will cause great harm to people, creatures and nature."

Ain, Yoder and others were silent.

This question is the one that bothers them the most.

In addition to strengthening the shielding measures, improving the safety factor, and installing a protective layer on the outside of the nuclear-powered vehicle, it seems that there is no other way.

Everyone is also thinking.

This is the most deadly problem.

Cost, shape, size, etc. are not that important, but safety is a threat to everyone's life.

At this time, the chief designer of the Berry Country New York subway system made a speech.

He said: "Master Commander, Professor Ain, I have a question, does the Raspberry State Nuclear Iron have to be built on the ground?"

"When I was designing the Raspberry New York subway system, one of the requirements was to prevent nuclear 'explosions' to a certain extent..."

"I did calculations at the time, and used indicators such as the explosive center, the short-range sub-center, the longer-distance explosive center, and the long-distance explosive center to evaluate."

"If the epicentre is 500 meters away from the explosion point, a solid fortification with a depth of at least 15 meters is required to survive. The safe depth is 70 meters. The [-]% death rate on the ground in this area makes it impossible to survive the general epicenter."

"The distance from the explosion point is 500 meters to 3000 meters to the sub-centre, and the depth is at least ten meters. The safe depth of the basement is about 30 meters. In this area, the survival rate is very low, but generally it will not Died instantly."

"As for the short distance between 7000 and [-] meters from the explosion point, three meters underground is enough!"

"Our New York subway, the depth is about six meters to ten meters."

"If the Berry National Nuclear Railway is built underground and built into a subway, then even if a nuclear leak occurs, the impact of the nuclear leak on the surface will be minimal because of the soil covering it!"

"It can play the role of transportation, and at the same time, it will not bring the threat of nuclear leakage. The best way is to build underground Raspberry National Nuclear Railway!!"

At this moment, Professor Ain and Yoder suddenly raised their heads, with excitement and surprise in their eyes.

"Yes, underground nuclear iron!!"

Professor Ain danced with excitement, "We were misled by the Dragon Kingdom!"

"We don't need to build the Berry National Nuclear Railway on the surface at all. If this kind of seriously dangerous train is built underground, the safety factor will be extremely high!"

"We can even open up a few more lines as backups!"

"If nuclear iron really appears underground, we can also bury this line and use other lines for transportation!!"

The chief engineer of Berry Country Peanut Town National Railway had fiery eyes and said, "Professor Ain, Commander, I have a more subtle idea!"

More subtle ideas?

People's eyes are focused on this talented engineer who built the Berry Country National Railway, with doubts and expectations in their eyes. .

Chapter 97Horse-Ridge cryogenic control chip, the savior of mankind!

"Everyone knows, what's the biggest difference between our Berry Country Nuclear Railway and the Long Country Nuclear Powered Changlong and Sakura Country's ring-country trains?" Everyone was puzzled and speculated.

"Berry Country's nuclear energy utilization technology is more advanced?"

"Longguo's high-speed rail is at the forefront of the world, and even we can't match it in the field of high-speed rail. Maybe their nuclear iron is better than ours in terms of size and speed?"

"Our nuclear power research is an absolute monopoly overlord. The nuclear power industry of Dragon Kingdom is still being sanctioned by us!"

Someone said mysteriously: "Our country has the largest number of nuclear 'aircraft carriers'. In addition to strong financial support, more importantly, we... have made considerable progress in the key technology of nuclear power miniaturization. achievement!"

Yoder nodded slightly, this is actually a global consensus.

The technology of miniaturizing nuclear power is currently only mastered by Berry Country, and it is impossible to overcome it without billions of dollars.

However, this miniaturization of nuclear power is still only used on nuclear 'aircraft carriers' and nuclear 'rockets'. For relatively small vehicles such as trains, the miniaturization of nuclear power is still not enough.

It has to be reduced in half again to fit on the train.

Yoder said: "The miniaturization of nuclear power is our Great Berry Country. Even the Bear Country with a well-developed heavy industry, they are only in the test stage of nuclear 'reactor' reactors."

"The Dragon Kingdom is probably between our country and the Xiong Kingdom. Their nuclear power miniaturization technology may already rank second in the world."

Having said that, Yoder is a little proud.

With these monopolistic cutting-edge technologies, ultra-fine machinery, etc., the Dragon Country still cannot surpass the Berry Country in a short time.

Professor Ain looked at the chief engineer who designed the Berry Country Railway, and said, "What's the biggest difference? Can our nuclear iron be built underground?"

"right!"

The chief engineer looked excited and said, "Or, it's not quite right."

"The biggest difference is that the trains of the Dragon Country and the Sakura Country are all on the surface, directly exposed to the severe cold of minus two hundred degrees!"

"Their trains cannot be replenished at any time. Once damaged, they must brave the extreme cold on the surface for repairs."

"And the Berry Country's nuclear iron was built in the Berry Country's fortress!"

"This means that our nuclear iron can be replenished at any time along the road just like trains and trains!"

"There are several problems that plague us now, and one of the toughest is the miniaturization of nuclear power plants, right?"

Professor Ain nodded, "Indeed, although we have miniaturized as much as possible because of the development of nuclear power plants for nuclear submarines. However, it is still too big for nuclear iron, and we still need to miniaturize it."

The chief engineer of Berry Country Railway slapped the table and said excitedly: "By the way, the way to break the situation is right in front of us!"

"I would like to ask you, as the designer of the New York subway system said, why should we...follow the footsteps of Longguo?"

"Dragon Kingdom wants to build a nuclear-powered dragon on the surface, but we can build it underground!"

"In this case, we can save precious space on the ground, and we don't have to worry about the train being too big and taking up space on the ground."

"And more importantly, the Dragon Kingdom and the Cherry Blossom Kingdom, they choose nuclear power to drive trains because their trains cannot replenish energy. They can hardly get resupply when they travel on the surface for a long time, so they have to use power generation efficiency. High nuclear power!"

A 1000-megawatt nuclear power plant only needs [-] metric tons of uranium fuel a year, which can be transported in one flight.

In stark contrast, fossil fuels.

The gap between the two is several million times.

That is to say, using nuclear energy, one voyage of aircraft can transport a year's electricity generation needs.

Instead of fossil fuels, only a few million voyages of aircraft can meet the consumption of fossil fuel power generation vehicles, that is, about five or six thousand cargo planes per year, transporting fuel non-stop.

"Professor Ain, Commander!"

"Our Berry Country can replenish energy at any time, so we don't need to design a nuclear power plant at all..."

"As an alternative, we can replace the nuclear power plant, which is difficult to further miniaturize, with a nuclear power battery!"

"Nuclear energy is also used, but the function of nuclear batteries is used to develop a high-voltage nuclear battery power generation system, which is between several hundred volts and several thousand volts, to replace diesel generators. This method can reduce the difficulty of development and reduce the To the bottom!! "

At this moment, the R&D department of Berry State Nuclear Power Co., Ltd. was quiet.

Everyone's breathing was heavy and their pupils trembled. Only then did they realize that they had been caught in a misunderstanding.

The Chief Engineer went on to say:

"Humanity's scientific and technological power is limited, and our Berry Country represents the highest technological power. But even so, there are still many difficulties to be overcome!"

"The nuclear power battery train has a relatively simple structure, is highly automated, and can even be unmanned."

"Our global positioning system has become more and more accurate, coupled with the advent of laser sensing technology, laser cameras, GPS and super intelligent computers, driverless driving has become possible."

Ain looked solemn, and asked: "Then, what about the technical solution for the nuclear power battery train you proposed?"

The chief engineer said: "To achieve all this, there are mainly several structures."

"The _th one is the car body°"

"The car body includes the interior equipment, car shell, underframe, bogie, etc. The exterior also needs to be equipped with nuclear battery supporting devices."

"The second is the central control system 0"

"We have conducted investigations and found that a huge problem that plagues the trains around the country of Sakura is whether it is possible to invent a computer that can withstand the extreme cold of minus [-] degrees. The information of Dragon Kingdom is too difficult to spy on, but I guess it will also be affected by this difficulty." live!"

"But our central control system does not need to consider extreme cold resistance."

"We can directly use off-the-shelf fully autonomous driverless systems, GPS, supercomputers, laser sensors, lidar, etc..."

"The central control system is remotely controlled. Through remote control, the fully automatic driving system can automatically realize the sleep, wake up, preparation, self-inspection, automatic operation and accurate parking of the train. It can also self-destruct when an accident occurs, thereby burying the Battery radiation."

"Radar can provide the position, distance change, orientation and high-speed information of foreign objects or sundries on the track through electromagnetic waves."
