摘要:
The steam generator includes: a water supply channel for supplying a secondary coolant to a tube bundle outer casing with the secondary coolant being isolated from the recirculating secondary coolant; a recirculating secondary coolant injection section for injecting the recirculating secondary coolant toward a high temperature-side heat transfer tube bundle; and a supplied secondary coolant injection section for injecting the secondary coolant supplied from the water supply channel toward a low temperature-side heat transfer tube bundle. The recirculating secondary coolant injection section and the supplied secondary coolant injection section being disposed in the tube bundle outer casing on the side toward the tube plate. The recirculating secondary coolant injection section and the supplied secondary coolant injection section are defined such that, of the secondary coolant and the recirculating secondary coolant, the coolant having a higher relative flow rate than the other flows at a lower velocity.
