Everyone knows about nuclear-powered submarines, but why are there no nuclear-powered planes?

Due to the limitations of existing technical conditions and related use and training factors, nuclear-powered aircraft have not appeared. Although many countries have tried in these aspects, they finally feel that the nuclear-powered aircraft manufactured in this environment is too small, so there is no nuclear-powered aircraft that can be applied to actual operations.

Nuclear power plants need to meet many conditions when working, so the external facilities are relatively large and light, and can only be carried on large facilities.

The ship has a large displacement, so there is more space to accommodate more facilities. Therefore, after the nuclear power technology is mature, it will be used on ships first to meet the power demand of ship navigation, and then nuclear-powered submarines will be developed, and the application scope will be wider and wider.

With the development of technology, the scale of nuclear power plants is gradually decreasing, and the application conditions are increasing. As early as the 1950s, the United States began to study nuclear-powered aircraft, but the size of this aircraft is still very large, and there are few application conditions. Once the plane crashes, there will be many potential nuclear radiation risks, which are of little use value, so the plan was forced to be cancelled.

Once the nuclear-powered aircraft appears, the troops need to be trained frequently after assembly, and most of the aircraft training areas are in their own airspace. Once an accident happens to an airplane, it is easy to pose a threat to one's own safety. The range of nuclear radiation is very wide. No country can tolerate dangerous nuclear warheads floating in the sky all the time. Unless it can be guaranteed that the nuclear power plant will not explode when the plane crashes, it will not be manufactured and assembled in a short time.

Since the Cold War, all major nuclear-armed countries have signed relevant agreements and promised not to be the first to use nuclear weapons. When attacking the enemy, the nuclear-powered plane must pass through the enemy's control area. Once the plane crashes, it is equivalent to hitting the enemy between nuclear warheads. Therefore, we call on the whole country to ban the emergence of nuclear-powered aircraft, which is a disguised nuclear weapon.

Nuclear-powered aircraft are also in great danger during driving, but the environment is very complicated. After the plane was damaged, it had the opportunity to fly back to its own airport. However, the leaked nuclear power plant will cause harm to pilots and armed personnel of the country, so nuclear-powered aircraft are also very dangerous weapons for the people of the country.

Based on the above conditions, nuclear-powered aircraft only exist in concept, and all major countries will carry out experimental development, but never thought of using it as a practical application. Perhaps there are models of nuclear-powered aircraft in laboratories in many countries, but it is really hard to find them in real life.

All the nuclear power plants that can be used in practice now are nuclear fission devices, which are not only very polluting, but also very dangerous. When the technology is mature in the future, nuclear fusion can be applied to real life, and nuclear-powered aircraft powered by nuclear fusion may appear.
