It is true that the atomic bomb is not difficult to build.
The threshold for building an atomic bomb has never been a technical problem, but how to make others not know how to save so many first-class raw materials.
The principle of the atomic bomb has long been announced, and it would not be much difficult to build an atomic bomb without the existing technological capabilities.
However, the materials for the atomic bomb are very troublesome.
There are two main nuclear charges of atomic bombs, one is U235 and one is Plutonium-239.
Both have a variety of isotopes, and specific isotopes are required for use.
U235 is relatively simple to make a nuclear bomb, but U235 is very low in purity in nature, mainly U238, which needs to be separated.
Normal is only 0The 7% concentration of U235 can be purified to more than 90% before it can be used as a raw material for the atomic bomb, a process calledUranium enrichment
The most common method of uranium enrichment is the use of gas centrifuges to separate the atomic weights of different isotopes.
But this requires a large number of centrifuges and consumes a lot of power.
That's why small countries can't build atomic bombs, because you need too much electricity to enrich uranium. This is also why a certain country can be found to enrich uranium, because you need a lot of electricity, a lot of enrichers, and this is basically impossible to hide.
The countries that have built the atomic bomb have either started to do so at an early stage and entered the nuclear club, or they have been supported by someone behind them, acquiescing or even supporting it.
Together, these club members have also developed a nuclear non-proliferation treaty, which is essentially to restrict other countries from doing so.
The means of restriction is to monitor global uranium enrichment activities.
Chinese have become accustomed to the so-called self-reliance, the so-called whole-system industry, the so-called independence, and often do not realize that many countries in the world actually do not have an industrial system.
As for the manufacture of the previous centrifuge, the principle is not complicated, but the electricity is troublesome.
Electricity requires a series of infrastructure to reach a certain level.
And the consumption of electricity can also be estimated.
So, if that country wants to build a large-scale February ** dynamic incentive program to build electricity, or large-scale import of electricity from abroad, then the so-called "international community" will notice whether you are ready to enrich uranium.
Therefore, it is not that the vast majority of countries cannot build atomic bombs, but that the vast majority of countries are banned from developing atomic bombs.
