PROTECTION SYSTEM OF UNDERGROUND NUCLEAR POWER PLANT FROM UNDERGROUND MIGRATION OF RADIOACTIVE LIQUID WASTE Russian patent published in 2018 - IPC E02D31/00 

Abstract RU 2648364 C1

FIELD: security systems.

SUBSTANCE: invention relates to the safety system of underground nuclear power plants, and more particularly to the safety system of a subterranean nuclear power plant from underground migration of radioactive liquid waste. Safety system of the underground nuclear power plant contains a protective layer (S) of the reactor pit, wherein the protective layer (S) comprises an inner lining (S1), drainage layer (S3) and crack filling layer (S2). Impermeable layer (Z), in which the inner liner is made to prevent exosmosis of the internal water. Drainage layer is made to collect and drain the seepage water. Reactor pit is surrounded by an inner lining, drainage layer and crack filling layer. Impermeable layer (Z) is placed along the periphery of the underground cavernous group. Underground cavernous group contains the reactor pit and auxiliary shaft. Impermeable layer is made with the possibility of isolating an underground cavernous group from natural groundwater.

EFFECT: technical effect: ensuring the effectiveness of the underground nuclear power plant safety system from underground migration of radioactive liquid waste.
