摘要:
An apparatus for cooling a spent fuel pool having a heat exchanger includes a cooling water pool positioned above the spent fuel pool; a floating device configured to be elevated according to a water level of a cooling water in the spent fuel pool; and an emergency cooling water supply pipe configured to form a path through which the cooling water of the cooling water pool is moved to the spent fuel pool and configured to include a floating valve that opens or closes a flow passage of the cooling water in connection with the elevation of the floating device.
摘要:
An apparatus for charging an emergency battery, which provides an emergency power to an emergency core cooling apparatus including an electric pump or a steam pump includes a thermoelectric generation device configured to detect a decay heat and a residual heat produced in a nuclear power plant and configured to convert the detected heat to an electric energy; an electric energy conversion unit connected to the thermoelectric generation device to output a current generated in the thermoelectric generation device as a constant voltage; and the emergency battery configured to store a power outputted from the electric energy conversion unit.
