Title:
NUCLEAR POWER PLANT HEAT TRANSPORT APPARATUS AND HEAT TRANSPORT METHOD
Document Type and Number:
Japanese Patent JP2014149176
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve cooling capability and reliability of a heat transport apparatus by always monitoring a refrigerant amount and inject or discharge the refrigerant so that the amount maintains to be a specified amount while the heat transport apparatus operates.SOLUTION: The heat transport apparatus comprises: a heat receiver 1 with at least one heat receiving tube 1a installed in a cooling object pool 21; a vapor-phase refrigerant transfer pipe 3 for transferring a vapor-phase refrigerant 5a generated in the heat receiver to a radiator 2; a liquid refrigerant transfer pipe 4 for transferring a liquid-phase refrigerant 5b condensed in the radiator to the heat receiver; a liquid level measurement device 8 provided to measure a liquid level of the refrigerant at a location lower than the top end of the heat receiver 1; and at least one refrigerant injection pipe 6 and one refrigerant discharge pipe 7 connected to the liquid refrigerant transfer pipe 4.
