How to deal with nuclear sewage in other countries?

In other countries, the treatment method of nuclear sewage is to turn it into steam and discharge it into the atmosphere, into the deep underground and electrolytic treatment.

1, turned into steam and discharged into the atmosphere.

The principle of this scheme is to evaporate the water in nuclear waste water into water vapor by using an evaporation device, while the radioactive substances are left in the water. Then the water vapor is discharged into the atmosphere, and the concentrated solution containing radioactive substances is stored in a storage tank. This scheme can reduce the total amount of nuclear waste water, but it will also increase the difficulty and risk of concentrated solution storage.

2. Go deep underground.

This is a scheme to discharge nuclear waste water into the depths of underground rocks through underground pipelines. There are some technical problems and security risks in this scheme.

3. Electrolytic treatment

This is a scheme to convert tritium in nuclear waste water into tritium gas by electrolysis technology, and store or discharge it. This scheme can effectively remove tritium from nuclear waste water, but it also needs a lot of electricity and equipment.

Disposal method of nuclear waste:

1, deep underground method

Buried in the ground. Many countries have established many deep geological reservoirs, which are usually hundreds of meters deep, and you can't see them when you look around. The nuclear waste inside is treated by curing and sealing technology, which can prevent nuclear waste from leaking and can be stored for more than 1000 years.

2. Nuclear fuel cycle technology

This technology can recover plutonium and uranium for reuse. Large-scale systems such as light water reactors can also be recycled, mainly for waste utilization. This can prolong the service life of nuclear fuel.

3, high temperature oxidation method

In this method, nuclear waste is directly exposed to an oxidant with a very high temperature, and the oxidant is decomposed into various harmless substances. In this case, because the radioactive elements in the nuclear waste have been completely decomposed, there is no risk of re-release.
