<p>PROBLEM TO BE SOLVED: To provide a structure of a nuclear power plant capable of saving a life, maintaining a nuclear reactor and supplying power, and a new structure of nuclear power generation which can continue to feed cooling water even when the nuclear reactor is suffered and submerged and hardly causes melt-down or melt-through.SOLUTION: In a new small-size condensate structure, a part of condensate is used as condensate promotion medium, while dragging condensate side vapor into condensate injection nozzle air flow made by injecting the promotion medium to a ring nozzle and mixing condensate turned to a low temperature according to adiabatic expansion and condensation side vapor and the condensate of vapor is promoted. Subsequently, various kinds of cutoff valves are provided near a nuclear reactor and are cut off at emergency. Further, a mount is constructed in the neighborhood, necessary sub facility is disposed on the mount, such a structure as to pass through a roof floor of a nuclear reactor building, be piped on a frame communicated with the mount and be connected to the sub facility through a bypass course is provided and, even when the nuclear reactor which is coupled with the sub facility and has close tightness is submerged, the new structure can be operated. The new structure hardly causes melt-down or melt-through and, even when being submerged, continues to be operated and does not require alternate power generation.</p> |
