Miniature Nuclear Fission Reactors!
A nuclear reactor was not a complicated thing. With high school physics knowledge, one could theoretically build a nuclear reactor.
To put it bluntly, it was a steam generator. In principle, it was exactly the same as conventional coal power generation, except that the heat generated by the steam came from a nuclear reaction.
As for nuclear reactions, nuclear fuel had a critical mass. For example, the critical mass of uranium raw materials for nuclear power was about 5.5 kilograms. As long as the weight of the gathered uranium raw materials exceeded 5.5 kilograms, it would automatically start a chain reaction, consume mass, and release a huge amount of heat.
Of course, this chain reaction was actually a nuclear explosion, and its lethality was equally shocking. Japan had already verified this.
As a country famous for its craftsman spirit, Japan had always liked to do everything to the best of its ability. Including the two nuclear power plant explosions in just 11 years, they were all perfect and unique, leaving their names in history.
Therefore, Japan became the only epic-level country in the world that had eaten two nuclear bombs and caused two nuclear accidents.
No one wanted to be such an epic protagonist. Therefore, a normal nuclear reactor would install a neutron source to output stable neutrons, and install a graphene rod to absorb the neutrons to control the speed of the chain reaction.
However, theoretically speaking, breaking through the critical mass to trigger a nuclear explosion and releasing heat to generate electricity was still feasible. All that was needed was a thick enough wall.
However, nuclear reactions required nuclear fuel. This was something that was strictly controlled all over the world. It was impossible for ordinary people to obtain it.
However, this wasn't a problem for important national departments such as the China National Space Administration.
Then for Jiang Chen, it was not a problem at all.
This was because he had dismantled all the nuclear batteries on the spacecraft. These nuclear batteries were filled with Pu, which was an ideal nuclear material.
Of course, the more ideal use was to use it as a nuclear bomb, but a nuclear bomb was obviously not what Jiang Chen needed, nor was it necessary, because he didn't have a rocket or an aircraft.
Otherwise, he would have been interested in making a miniature nuclear bomb out of the Pu, changing the number of nuclear explosions in Japan to the legendary five.
However, it was easy to create a miniature nuclear bomb, but it was very difficult to create a miniature nuclear reactor.
In recent years, with the continuous development of science and technology, the requirements of humans for power had become higher and higher. Meanwhile, the size of the engine began to decrease.
Take the mech that Jiang Chen planned to modify as an example. It needed powerful power, but it didn't have a lot of space to accommodate an engine.
Many equipment had the same problem!
Therefore, to be able to invent a small, high-power engine was the dream of almost all researchers!
The nuclear engine was the most powerful engine that humans could imagine up until now!
Among them, for humans today, nuclear fusion engines only existed at the concept level!
Of course, it also existed in science fiction movies and novels.
For so many years, countless researchers from all over the world had been working on the nuclear fusion engine.
However, after countless attempts and failures, they had no choice but to conclude that nuclear fusion engines would only appear in the next few hundred years!
The current level of technology was still far from being able to create such a thing!
However, nuclear fission engines, or rather, miniature nuclear fission reactors, were feasible.
Countries had already completed the miniaturized phase of nuclear reactors. This process actually happened 70 years ago.
However, although the principle of a nuclear reactor was simple, its structure was very complicated. In addition to its own reactor, it also needed multiple protection and cooling systems.
The difficulty of designing these system fortresses into an extremely small space was obvious. At least in the years since the birth of nuclear power, only three countries had mastered the technology to miniaturized nuclear reactors.
As for ordinary people, it was completely impossible for them to get their hands on the blueprint of the miniature nuclear reactor. After all, even those old industrial countries had worked hard for so many years but still did not have it.
But for Jiang Chen, this wasn't a problem!
Because, besides being a civilian scientist, he was also a transmigrator with a powerful system!
He already had the relevant knowledge, and he also had the system to assist him!
With the system's blueprint, it was not difficult to modify a nuclear reactor based on the original nuclear battery of the spacecraft!
After all, the principles of the two were similar, and their structures were similar. It was just that their uses were slightly different.
Nuclear batteries were about continuity. A satellite had to stay in the sky for decades, and its energy had to be provided by nuclear batteries.
As for nuclear engines, they naturally required power. The greater the power output, the better.
With the blueprints given by the system, Jiang Chen only took a few days to build the nuclear engine.
Regarding this, he did not have much fluctuation in his heart.
"Next, it's time to test if this engine meets the requirements.”
Jiang Chen pressed the switch.
