According to the Russian Satellite Network reported on the 8th, Russian scientists have discovered a bacterium that can neutralize nuclear waste in the nuclear waste storage site in Siberia. This unique bacterium is expected to be used as a natural barrier to prevent the spread of radionuclides.
Researchers at the Frumkin Institute of Physical Chemistry and the Federal Biotechnology Research Center of the Russian Academy of Sciences have isolated this microorganism that can be used to protect the surrounding environment from liquid radioactive waste.
They discovered the above-mentioned bacteria during a groundwater microbiological study of the Seversk deep radiation burial site in Tomsk region of Siberia. The area stores liquid radioactive waste from the Siberian Chemical Union, which mainly reprocesses low-enriched uranium used to make nuclear fuel.
The research was published in the latest issue of the Russian scientific journal Radioactive Waste. Studies have shown that the bacteria can make radionuclide ions (including ions found in uranium and plutonium) "inactive", thereby preventing dangerous radiation from spreading into the surrounding environment, and scientists can precisely adjust the bacterial work place Required environment.
The researchers say that their discovery is the first step in creating a biogeochemical barrier for radionuclides that can be used in deep buried areas containing liquid radioactive waste.
Since the 1980s, scientists have been working on microbiological Tools that limit the impact of nuclear waste, noting that microbial processes must be considered in projects that bury and store nuclear waste. (Reporter Liu Xia)
