Abstract

The invention provides an irradiation resisting graphene coating with enhanced corrosion resistance and thermal conductivity. The graphene coating treatment technology is adopted for a high-level waste glass form container. The thickness of the graphene coating is 1-10 [mu]m and covers the outer surface of the high-level waste glass form container. The high-level waste glass form container is made of an Austenitic stainless steel material and is 2-10 mm thick. According to the irradiation resisting graphene coating with the enhanced corrosion resistance and thermal conductivity, through the excellent physical and chemical properties of graphene, the corrosion resistance of the processed container can be improved, and decay heat of high-level waste glass forms can be guided out in time, so that the performance of the container is improved, the service life of the container is prolonged, and a temporary library is additionally arranged.

Description

Technical field

[0001] The invention relates to a graphene coating treatment technology for a container containing a glass solidified body of high-level radioactive waste, which improves the corrosion resistance and thermal conductivity of the container. Background technique

[0002] The safe disposal of high-level radioactive waste is one of the outstanding issues facing the development of nuclear energy and the utilization of nuclear technology, and it is also the key and difficult issue of radioactive waste management. Geological disposal is considered to be the most promising disposal plan. “Geological disposal” refers to the disposal of solid radioactive waste in facilities in stable underground geological structures (usually hundreds of meters or more below the surface) to make radioactive waste Long-term effective isolation from the biosphere. It takes the containment and isolation of radionuclides as the core content, uses multiple barriers (including waste bodies, packa...
