摘要： A fast breeder reactor has a nuclear reactor container (11) filled with a liquid metal, a reactor core (15) disposed within the nuclear reactor container (11), and a first supporting structural member (32) which is mounted to the nuclear reactor container (11) such as to support the reactor core (15). The fast breeder reactor is provided with a cylindrical structural member (21) which surrounds the periphery (24) of the reactor core (15) such as to define an annular gap (40) between the cylindrical structural member (21) and the reactor core (15) for allowing the liquid metal to exist therein, the cylindrical structural member (21) being mounted to the nuclear reactor container (11) by means of a second supporting structural member (39). The inertial resisting force produced when the liquid metal existing in the annular gap (40) will flow out from the annular gap (40) in response to the vibration of the reactor core (15) acts such as to suppress the vibration of the reactor core (15), thereby allowing an improvement in the anti-vibration properties of the fast breeder reactor.

摘要： PURPOSE:To prevent a stress from being caused by a restraint resulting from thermal expansion by providing below a container a plate-shaped deflection stopper which inclines in the same direction as that of the thermal expansion of the lower part of this container, and embedding this deflection stopper in the powder contained in stationary containers. CONSTITUTION:A safety container deflection stopping chamber 6 is of a box structure which is filled with a powder 8. A reactor container deflection stopper 5 is inserted into this powder 8 and anchored thereby in the deflection stopping chamber 6. Such chambers 6 are formed integrally with a container deflection stopper 7 which is fixed to a building, thereby restraining a reactor container 1 from a horizontal displacement due to earthquake. The reactor container deflection stopper 5 is set at an angle Q to the axis of the reactor container 1. A path swept out by the thermal expansion of the reactor container deflection stopper 5 is at the angle Q to the axis of the reactor container. This deflection stopper 5 moving in the powder along this path alone, this structure prevents its movement from being restrained by the powder at the time of its thermal expansion. On the other hand, the powder behaves against the deflection as in the case of a steel body, exerting a perfect controlling effect.

摘要： PURPOSE:To reduce powder reaction generated at the bottom part of the nuclear reactor container owing to heat expansion by restraining the horizontal displacement of a nuclear reactor vibration stopper by powder. CONSTITUTION:The nuclear reactor 1 is fixed to the pedestal 9 of a building structure with a flange 2 and suspended and a safety container 3 which surrounds the outer periphery of the container 1 is fixed to the building structure with a flange 4 and suspended. Then a safety container vibration stopper 7 supports a conic nuclear reactor vibration stopper 5 through the powder 8 and a container deflection stopper 7 fixed to the building restrains the horizontal displacement of the container 1 in case of an earthquake, thus constituting the antiseismic support structure 10. Consequently, even if the container 1 expands thermally and the tilt angle theta of the vibration stopper 5 varies, the tip part of the vibration stopper 5 is not restrained substantially, so the powder reaction is suppressed to hold the support function of the nuclear reactor container even in case of the earthquake.
