摘要： The purpose of the present invention is to prevent a nuclear reactor building from being pressurized and heated again when the nuclear reactor building is cooled in the event of a severe accident. The present invention comprises: a reservoir tank in which cooling water is stored; a partition part which is disposed in the reservoir tank and partitions the inside of the reservoir tank into a first storage tank and a second storage tank so as to separate the cooling water in the reservoir tank; and an inflow part which is disposed in the partition part and allows the cooling water of the second storage tank to naturally flow into the first storage tank by the difference between the water levels of the first and second storage tanks when the water level of the first storage tank is lowered.

摘要： The present invention relates to a passive nitrogen injecting device for a nuclear reactor coolant pump, the device comprising: a nitrogen supply unit for supplying nitrogen; a pressure control valve for controlling the supply of nitrogen from the nitrogen supply unit according to pressure; an accumulator for filling the nitrogen supplied through the pressure control valve at a set pressure, and supplying the filled nitrogen in the event that an accident involving coolant loss occurs; and an isolation valve for controlling the supply of the nitrogen from the accumulator into a seal housing of a nuclear reactor coolant pump. The present invention uses an accumulator so as to be able to supply nitrogen by using the pressure in the accumulator without the supply of external power in the event of an accident involving coolant loss, and therefore has the effect of being able to improve safety.
