摘要： A heat transferring device includes a pumping structure, and more specifically, a heat transferring device having a pumping structure, in which a working fluid of a cooling part is movable in an upward direction without a separate power source, and capable of using gravity while recovering the working fluid, and applying various heat sources to a heating part. To this end, a heat transferring device includes a heating part configured to heat a liquid working fluid and change the liquid working fluid to a gas state, a cooling part configured to cool the gaseous working fluid supplied from the heating part and change the gaseous working fluid to a liquid state, a pressurizing part configured to allow the heating part and the cooling part to communicate with each other so that the gaseous working fluid pressurizes the liquid working fluid, and a recovery part configured to move the liquid working fluid supplied from the cooling part to the heating part.

摘要： The application provides a self-diagnosis and accident-handling unmanned nuclear reactor, which: can passively cool down excessively generated heat without an operation of an operator when a malfunction of the nuclear reactor has occurred, wherein a cooling operation for safety measures can be carried out in a completely passive manner without a separate control command by a change in environmental conditions such as the structure and pressure of the nuclear reactor; and has a simpler structure compared to that of a conventional nuclear reactor safety system. It also provides a self-diagnosis and accident-handling unmanned nuclear reactor, which performs heat exchange by using a two-phase heat transfer mechanism, wherein heat exchange performance is maximized by introducing a spray-type heat exchanger having an optimized structure in which channels are three-dimensionally arranged, and can also easily and passively control heat exchange without a separate control means by using saturated steam pressure.

摘要： The present invention relates to a passive infinite cooling system for a nuclear reactor and a method of operating the same. The system includes an energy release space in which a reactor vessel is accommodated, an energy absorbing space separated from the energy release space, an energy transfer space, which is provided above the energy absorbing space, absorbs and cools heat transferred from the reactor vessel, and discharges the absorbed heat to the outside through an outer wall thereof, a first cooling flow path through which the heat in the reactor vessel is transferred to the energy transfer space, a pressure balance pipe through which the pressure in the energy release space is transferred to the energy absorbing space, and a coolant spray pipe through which the cooling water in the energy absorbing space pressurized by the pressure balance pipe is transferred to the energy transfer space. The energy transfer space includes a saturated vapor pressure cooling chamber, which is formed to be connected to an inner side of an upper outer wall of the cooling space, and in which cooling water is accommodated, a heat exchanger of the first cooling flow path is located, and a spray-side end of the coolant spray pipe is located, and a reference atmospheric pressure chamber, which is provided below the saturated vapor pressure cooling chamber and communicates with the saturated vapor pressure cooling chamber, is filled with air so as to achieve a pressure balance with the cooling water in the saturated vapor pressure cooling chamber, and in which a water level thereof varies according to a pressure in the saturated vapor pressure cooling chamber.
