Nuclear wastewater ≠ nuclear wastewater!

Water and liquid 5 moisten absorbent 3 and evaporating layer 1, and evaporate on the surface of evaporating layer 1, which is more than 100 times faster than the evaporation rate of free water; Floating evaporator 12 Floating on the surface of the water using the capillary phenomenon of water replenishment, hanging evaporator using water gravity flow and capillary phenomenon of water replenishment, without control can run.

Patent "An adsorbent for highly efficient absorption of cesium ions and its preparation method and application" (public number: CN115554993A), provides a convenient one-step solvent method to prepare an adsorption material that can efficiently and reliably remove and solidify cesium ions. The invented NI-COPBAS adsorbent has excellent cesium removal efficiency, manifested as fast removal speed, large cesium enrichment capacity, high ion screening function and adsorption selectivity for Cs.

Nuclear waste water has low radioactivity and low risk, so it can be treated by simpler methods to meet discharge standards or reuse standards.

Commonly used radioactive precipitation, ion exchange, concentration and evaporation, reverse osmosis, photocatalytic oxidation and other methods to remove tritium or other trace radioactive substances.

For "nuclear wastewater" related patent applications, there are nearly 4,000 worldwide, Japan alone accounted for 24%, in the field of technology, the largest number of patents is about "treatment of radioactive contaminated materials; And its decontamination device (IPC classification number: G21F9/00) "related patents, with Toshiba and Hitachi Group as the main applicants.

China also has more than 100 patents related to "nuclear wastewater", mainly from universities and enterprises.

However, in terms of "nuclear waste disposal", China has a technology that is coveted by all major powers, that is, "Star 2".

It is a device developed in China for the work of nuclear power plants, lead-based nuclear reactor zero power device, mainly used in the work of nuclear power plants, not only the use of nuclear fuel efficiency to 95%, but also the waste generated after the consumption of nuclear fuel, recycling.

The lead in the spacecraft not only deradiates the waste, but also converts the energy it releases back into electricity.

Here we have to mention the "ADS transmutation system", proposed in the 1990s, ADS is the transmutation of radionuclide waste, effective use of nuclear resources and nuclear energy production device.

The International Atomic Energy Agency (IAEA) has included its transmutation reactor in a new nuclear energy system called "Emerging Nuclear Energy systems for Nuclear waste Transmutation and energy generation."

China is also the first country in the world to carry out the development of ADS system large-scale engineering project. Qixingmingii was first critical at the end of 2016 by the China Institute of Atomic Energy and the Institute of Modern Physics of the Chinese Academy of Sciences.

Regarding ADS transmutation system, there are more than 240 patents in China, and the applicant (institution tree) is mainly Chinese Academy of Sciences, involving reactors, accelerators, bismuth alloys, spallation targets and other fields.

And this does not mean that it can completely solve the serious ecological problems caused by the discharge of nuclear sewage in Japan, after all, we have to face a large number of radioactive elements of nuclear sewage, rather than nuclear waste water generated by nuclear power plants.

We have enough reason to believe that our country has advanced technical strength to reduce the actual impact of the sea discharge as much as possible, and what we can do now is to remain firmly opposed to nuclear sewage discharge into the sea and establish a sense of protection.

I believe that countries that create ecological crises will also usher in due punishment, but the current damage to the ocean is irreversible, and will be returned to human beings in the future, there is no regret medicine to eat.

One patent is the unique Aoke key big data center, through the professional consulting team to clean the data and independent research and development, focusing on patent search, analysis, early warning and other functions of the search and analysis platform.
