Passive safety equipment for a nuclear power plant

A passive safety facility for a nuclear power plant, comprising:

• a cooling section formed to cool fluid discharged from a nuclear reactor coolant system along with fluid contained within an area between the nuclear reactor coolant system and a containment;
• and
• a circulation inducing jet device configured to receive the fluid discharged from the nuclear reactor coolant system, and formed to jet the received fluid to the cooling section, at least part of which is open toward an inside of the containment to entrain the fluid contained within the area between the nuclear reactor coolant system and the containment by a pressure drop caused while jetting the received fluid so as to jet the entrained fluid along with the received fluid, wherein
• the containment is formed to surround the steam generator which is configured to generate steam or the nuclear reactor coolant system which is configured to accommodate the steam generator,
• the circulation inducing jet device comprises:
• a fluid jetting section connected to the nuclear reactor coolant system to receive the fluid discharged from the nuclear reactor coolant system, and formed to jet the received fluid;
• a fluid entraining section formed in an annular shape around the fluid jetting section to entrain the fluid contained within the area between the nuclear reactor coolant system and the containment;
• a circulating fluid jetting section configured to surround the fluid jetting section with a portion having an inner diameter larger than that of the fluid jetting section to form the fluid entraining section, and supply the received fluid and the entrained fluid to the cooling section;
• a turbine blade rotatably installed at an outlet of the jetting section to induce the jetting of the received fluid;
• and
• a pump impeller connected to the turbine blade to rotate along with the turbine blade, and induce the entrainment of the fluid contained with the area between the nuclear reactor coolant system and the containment through the fluid entraining section.
