Title:
NUCLEAR PLANT PASSIVE COOLING SYSTEM USING SOLID-LIQUID PHASE CHANGE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/111672
Kind Code:
A1
Abstract:
The present invention comprises: a pipe including an inlet portion communicating with the inside of an object to be cooled and a discharge portion communicating with the outside thereof and receiving a coolant which is transferred therethrough to the inside/outside; an internal heat exchanger connected to the pipe disposed inside the object to be cooled; and an external heat exchanger connected to the pipe disposed outside the object to be cooled, wherein the coolant comprises a solvent received in the pipe and a phase change material (Na(CH3COO)3H2O) which is determined by a test apparatus and is introduced into the object to be cooled through the inlet portion and discharged to the outside of the object to be cooled through the discharge portion, to be circulated to the inside and outside of the object to be cooled along the pipe, thereby discharging heat inside the object to be cooled to the outside.
