Abstract

PURPOSE:To prevent the failure of a coolant vessel in a fast breeder by means of containing melted fuel when the vessel is failed, by setting up a group of trays at the underpart of a reactor. CONSTITUTION:A coolant vessel 2 of a reactor is set up at the wall of concrete 11 via a heat insulator 10, and a reactor vessel 4 is set up within said vessel 2. A core 3 is contained in the reactor vessel 4, and coolant is allowed to be cycled by a pump 6. The heat of the core 3 is utilized by the interposition of a heat exchanger 8. A plurality of group of fuels is arranged at the underpart of the reactor vessel 4 in which the core 3 is contained. The group of the trays if composed by arranging in a plurality of steps of a shelf such as a tray group of the first step, and a tray group of the second step. Even when melted fuel is penetrated and dropped by means of being melted by the loss of coolant of the nuclear fuel assembly of the core 3, and bottom surface of the reactor vessel 4 is melted, the vessel of the coolant is never failed owing to be dispersed and contained into tray groups by these melted fuel.
