摘要： To provide a fast reactor having improved structural reliability and excellent safety. A fast reactor 1 comprises: a reactor vessel 7 accommodating therein a reactor core 2 and a primary coolant 5; an intermediate heat exchanger 15 disposed in the reactor vessel 7, for transferring a heat energy of the primary coolant 5 heated in the reactor core 2 to a secondary coolant 45; an intermediate heat exchanger upper drum 15a disposed above the intermediate heat exchanger 15. Disposed above the intermediate heat exchanger upper drum 15a is an upper plug 10 having a neutron shielding function and a heat shielding function. A thermal-expansion absorbing unit 46 is disposed between the intermediate heat exchanger upper drum and the upper plug, for absorbing a thermal expansion of the intermediate heat exchanger upper drum in an axial direction and a radial direction of the intermediate heat exchanger upper drum, and defining a reactor cover gas boundary.
