Abstract
A passive cooling system for a nuclear reactor includes an energy release space in which a reactor vessel is accommodated, an energy absorbing space separated from the energy release space, and an energy transfer space above the energy absorbing space and configured to absorb and cool heat transferred from the reactor vessel and discharge the absorbed heat to an outside of the system through an outer wall thereof. The passive cooling system further includes a first cooling flow path configured to transfer the heat in the reactor vessel to the energy transfer space, a pressure balance pipe configured to transfer the pressure in the energy release space to the energy absorbing space therethrough, and a coolant spray pipe configured to transfer the cooling water in the energy absorbing space pressurized by the pressure balance pipe to the energy transfer space may be provided.
