The reason for this limitation of the cooling time is that the cooling water in the passive condensation tank 30 exchanges heat with the condenser 20 and its temperature gradually rises, and eventually even the situation that it cannot be condensed through the condenser 20 occurs.
[0008] Therefore, for an accident of about 8 hours, the passive auxiliary water supply system can operate smoothly by means of the passive condensate tank 30 to perform cooling, but when an accident such as the recent Fukushima nuclear power accident lasts for a long time, there is a possibility that the passive auxiliary water supply system cannot function question

The present invention relates to a water filling device for a passive auxiliary water supply system of a nuclear power plant. In the passive auxiliary water supply system equipped with a passive condensing tank, it further includes a raw water system that provides cooling water to the passive condensing tank during an accident, wherein the passive condensing tank A condenser that condenses steam of a steam generator that exchanges heat with condensed water and supplies it to a nuclear reactor. Various water filling sources can be used according to the present invention, which has the effect of prolonging the working time of the passive auxiliary water supply system.
Description
technical field [0001] The invention relates to a water filling device for a passive auxiliary water supply system of a nuclear power plant, in particular to a water filling device for a passive auxiliary water supply system of a nuclear power plant capable of providing raw water of the raw water system to a passive condensation tank. Background technique [0002] A nuclear power plant is a device that uses heat generated by nuclear fission of fuel to transfer heat to water passing through a steam generator to generate steam, and drives turbines and generators based on the generated steam to obtain electrical energy. [0003] A nuclear power plant needs to be equipped with a reactor core that preserves nuclear fuel and a nuclear reactor coolant system that transfers heat generated in the nuclear reactor to the secondary side to operate safely within the scope of design standards, thereby maintaining the safety of the nuclear power plant and preventing the spread of radioactiv...
