Why do nuclear power plants have to use domes?

Friends who like to watch documentaries about nuclear power plants, it is not difficult to find that the nuclear power plants in our country are basically hoisted with domes. So, the question is, why do nuclear power plants have to use domes?

Probably in the 60-70s, containment was used as an "optional design".It began to appear in some nuclear power designs, where it was used to cover the entire reactor and the main auxiliary systems. First, it can prevent foreign objects from impacting, as a shielding protection measure; Second, if an accident occurs, it is also a safety guarantee to ensure that radioactive materials are not leaked out.

As it happens, the dome is part of the containment. In the event of an extreme accident, the dome prevents radioactive gases from being released into the surrounding environment in the event of a breakage of the reactor pressure vessel.

Thus, as part of the containment, it has the effect of containing radioactive materialto buy time for people to evacuate and relevant departments to respond. Minimise the risk of accidents.

A nuclear reactor can be said to be the heart of the entire nuclear power plantIn addition to the reactor building, there are also important equipment such as steam generators and voltage regulators, and temporary storage of spent fuel is also required to achieve containment. Thus, containment also has a role to play in nuclear security.

Under the protection of the containment, these important strategic materials will not be easily dispersed. Of course, this is not a problem in our safe country, but not necessarily in other countries, and it is very important to know that the security of nuclear materials is very important!

In addition, its protective effect is also reflected in its ability to resist shocks, which is both earthquake and tsunami resistant, and the seismic effect can reach level 9. It can also withstand the impact of a large passenger aircraft Boeing 747It also withstands the blow of the regular **.

Because the dome is more conducive to the development of nuclear power plants.

This is certainly for security reasons to prevent nuclear divergence.

For safety reasons, and this is more effective.

It can play a protective role and prevent leakage.

On the one hand, it can bear its own weight, and on the other hand, it can withstand huge external impacts.

This is for safety reasons and for fear of safety incidents.

The dome was installed for safety reasons.

I guess it's because of the radiation protection.

I think it's for safety, and to receive a signal.

A nuclear power plant is a place to boil water. The steam can only be produced when the water is hot, and the steam can drive the turbine to rotate, and the rotating shaft tie mu leakage generator to generate electricity, this part of the production process is not fundamentally different from the general coal-fired gas power plant. In overseas Chinese language environments, such as Japan, the core part of the nuclear reactor, the pressure vessel, is called an atomic furnace.

Furnace, the furnace of the orange napper boiler.
