    • A fast breeder reactor has a nuclear reactor container filled with a liquid metal, a reactor core disposed within the nuclear reactor container, and a first supporting structural member which is mounted to the nuclear reactor container such as to support the reactor core. The fast breeder reactor is provided with a cylindrical structural member which surrounds the periphery of the reactor core such as to define an annular gap between the cylindrical structural member and the reactor core for allowing the liquid metal to exist therein, the cylindrical structural member being mounted to the nuclear reactor container by means of a second supporting structural member. The inertial resisting force produced when the liquid metal existing in the annular gap will flow out from the annular gap in response to the vibration of the reactor core acts such as to suppress the vibration of the reactor core, thereby allowing an improvement in the anti-vibration properties of the fast breeder reactor.
    • 快速增殖反应器具有填充有液态金属的核反应堆容器,设置在核反应堆容器内的反应堆核心,以及安装在核反应堆容器上以支撑反应堆堆芯的第一支撑结构件。 快速增殖反应器设置有圆柱形结构构件,其围绕反应堆芯的周边,以便在圆柱形结构构件和反应堆芯之间限定一个环形间隙,用于允许液态金属存在于其中,圆柱形构件被安装 通过第二支撑结构构件到达核反应堆容器。 当存在于环形间隙中的液态金属响应于反应堆芯的振动而产生的惯性阻力作用为抑制反应堆堆芯的振动, 快速增殖反应堆的振动特性。
