Latest Patents

Nianfeng Xu holds a patent for a "Migration prevention system for radioactive wastewater of underground nuclear power plant." This system is designed to prevent the migration of radioactive wastewater from an underground nuclear facility. The underground nuclear power plant includes a nuclear island with a group of underground caverns, which contain both a reactor cavity and auxiliary cavities. The migration prevention system features a protective layer that coats the reactor cavity and an impermeable layer that surrounds the nuclear island. The protective layer consists of an inner liner, a drainage layer, and a filling layer of rock fractures, arranged in that order. The inner liner is specifically designed to prevent the exosmosis of radioactive wastewater from the reactor cavity, while the drainage layer is intended to gather and drain any seepage water. The impermeable layer is strategically placed around the underground cavern group to isolate it from natural underground water.
