Russian “RosAtom” corporation is going to approve a concept for decommissioning of carbon-uranium reactors, which produce weapon-grade plutonium.
      
      Worked-out reactors will be buried in deep mines by means of a special technique. Reactors are not dismantled, but wrapped in a protective material and left in a mine, thus providing safety for thousands of years.
      
      Burying of one reactor costs about 2 billion rubles. Reactors, 13 of which was left in Russia, are expected to be buried in 2020-2025. All works will be funded by the Russian government.
