摘要： PURPOSE:To lessen an area where cooling water becomes hot in temperature by setting a water filling pipe in such a way that the pipe has a section which allows cooling water to flow upward within the water filling pipe of a cooling system so as to allow it to be poured. CONSTITUTION:In normal operations, since coolant flowing within a pressure container 2 is high in temperature, cooling water in a piping line 30 is naturally circulated by convection within the line because of convection heat transfer from the communication section of the container 2. Cooling water located in a place lower in level than the communication section is formed into cooling blocks, so that each temperature lamination is thereby formed within the pipe line 30. By this constitution, cooling water within a piping line 32 is increased in temperature mainly because of heat transfer, but the increase is small as compared with that of natural convection. Therefore, the loss in the heating value of the container 2 is reduced. Even if coolant is lost from the container 2 because of failures, hot and high pressure vapor within the container 2 is emitted to a pressure restraining pool 5 and a dry well 3 with both an escape valve and pressure reducing valve released, a check valve 29 is opened when pressure is lowered down to pressure which enables coolant to be poured in, and cooling water within a gravity fall water container 26 is poured in the container 2, so that a furnace core 1 is thereby kept submerged. In this case, since temperature within the piping line is low, water will never be boiled within the piping line, water can thereby be poured in a liquid phase.

摘要： PURPOSE:To safely cool the reactor containment after loss-of-coolant accident even with the failure of a vacuum breaking valve. CONSTITUTION:During a loss-of-coolant accident, when the pressure in the drywell becomes lower than the pressure in the wet well owing to the heat removal effect of a condenser 80, a check valve 53 opens and the gas in the wet well flows back through the path, gas exhaust pipe 74, condenser 80 to intake pipe 90 and returns to the dry well 3. When the pressures in the dry well and wet well become equal, this flow stops, then, the pressure in the dry well 3 becomes higher than the pressure in the wet well due to the decay heat generated in the core, the noncondensible gas flows through the intake pipe 90, condenser 80 and gas exhaust pipe 74, and eventually the check valve 53 closes again.
