A fast reactorincludes: a reactor vesselaccommodating therein a coreand a primary coolant; a core supportsupporting the corefrom below; and a bulkheaddisposed on the core support, the bulkheadextending upward and surrounding the corefrom a lateral side. Between an inner surface of the reactor vesseland the bulkhead, there is disposed an intermediate heat exchangerconfigured to cool the primary coolant, and an electromagnetic pumpconfigured to pressurize the cooled primary coolant. A neutron shieldsupported by an upper supporting platefrom above is disposed below the electromagnetic pump. The upper supporting platehas an opening. Between an outletof the electromagnetic pumpand the upper supporting plate, there is disposed a coolant guide mechanismconfigured to guide the pressurized primary coolantfrom the electromagnetic pumpto the neutron shield through the openingof the upper supporting plate
