摘要： PURPOSE:To thin the liquid film of the surface of a heat-transfer tube to contrive the improvement of condensation performance by providing a plurality of vertical heat-transfer tubes opened to connect to a pair of tube plates connected to the lower and upper ends of a vertical cylindrical drum set in a pool so as to quickly drop and remove condensed water. CONSTITUTION:A plurality of vertical heat-transfer tubes 24 are connected to a pair of tube plates connected to the lower and upper ends of a vertical cylindrical drum 23 set in a pool 12 and a plurality of legs so as to form a space among inlet tubing 3 connected to the upper part of the drum 23 or an upper tube plate 21, outlet tubing 7 connected to the lower part of the drum 23 or a lower tube plate 22, the bottom face of the pool 12 connected to the drum 23 and the tube plate 22. When a main steam tube connected to a reactor pressure vessel 2 is isolated, steam is allowed to flow through a tube 3 of a reactor emergency condenser 6a from the vessel 2 to introduce into the drum 23 to heat-exchange with the outside of a tube 24, to condense so as to return to the vessel 2 from a tube 7. At this time, because the tube 24 is vertically set, condensed water falls by gravity most quickly and has a shape to be removed therefrom, the liquid film formed on the surface of the tube 24 is thinned to obtain high condensation ability.

摘要： PURPOSE:To eliminate the need for disposing a diesel generator, etc., to be exclusively used by driving a pump by means of a turbine which is operated by reactor steam. CONSTITUTION:A sluice valve 2, an injection valve 5 and a regulating valve 8 are opened in the event of generation of such a situation that control rods cannot be inserted in a nuclear reactor 7. The steam generated in the reactor 7 is introduced through the valve 8 from a piping 9 to a turbine 10 to drive the turbine 10 and the pump 8 and is further introduced through a piping 11 to a pressure suppression pool 12 where the steam in condensed. On the other hand, the boric acid water stored in a boric acid water tank 1 is introduced through the sluice valve 2 into the pump 4 from a piping 3 and is driven by the pump 4 so as to be injected through the injection pipe 5 into the reactor 7 from a piping 6. Since the specified rotating speeds of the turbine 10 and the pump 4 are maintained constant at this time, the flow rate of the boric acid water to be injected is constant. The boric acid water is injected to the reactor 7 by such constitution without using a motor-driven pump and, therefore, the need for the emergency diesel generator, etc., is eliminated even in the state of the loss of a power supply and the improvement in reliability, etc., are attained.
