Apparatus for charging atomic power plant emergency battery by using thermoelectric generation element

Abstract

The present invention relates to an apparatus for charging an emergency battery for supplying emergency power to an emergency core cooling apparatus in an atomic power plant. According to the present invention, by providing the apparatus for charging the emergency battery, which supplies the emergency power to the emergency core cooling apparatus, by using a thermoelectric generation element, the emergency core cooling apparatus can normally perform a cooling function and atomic reactor damage due to overheating of the core can be effectively delayed or prevented.

Description

Technical field [0001] The present invention relates to an emergency battery charging device for providing emergency power to an emergency core cooling device of a nuclear power plant, and more specifically to an emergency battery charging device, which generates a temperature difference in a nuclear reactor, high temperature pipe, low temperature pipe, and steam in a nuclear power plant system Install thermoelectric power generation elements at generators and other locations to utilize the decay heat and waste heat generated in nuclear power plants. Background technique [0002] Although the design of nuclear power plants using light water pressurized water reactor type nuclear reactors fully considers the safety margin, unexpected safety accidents may occur. In the event of a large amount of cooling water leakage or power supply interruption, if sufficient emergency cooling water cannot be supplied, the nuclear reactor core will overheat and accidents of nuclear reactor damage ...

Problems solved by technology

[0007] The prior art used to cool the core when an accident occurs includes South Korean Authorized Patent No. 10-056876 (the emergency core cooling water is detoured and directly injected into the nozzle), Korean Authorized Patent No. 10-0419194 (using nuclear reactor protection containers and There are many methods and devices for emergency core cooling of the compression box), but there is no disclosure that when the emergency core cooling device has a power interruption accident, in order to smoothly supply power to the emergency core cooling device, the heat generated by the nuclear reactor is used by the thermoelectric power generation element.
