    • There is provided a residual radioactive sludge liquid suction apparatus capable of safely and surely sucking radioactive sludge liquid remaining in a sludge storage tank with no fear of being exposed to radiation at a time when a small amount of sludge liquid remaining in the sludge storage tank is transferred to another tank. The suction apparatus is a residual radioactive sludge liquid suction apparatus used for sucking residual radioactive sludge liquid (L) at a time when the residual sludge liquid (L) remaining in a sludge storage tank T1 is transferred, and includes: a suction apparatus body 1; three hover skirts 2 mounted to the suction apparatus body 1; a suction head 8 mounted to the suction apparatus body 1 and configured to suck the residual sludge liquid (L); air jetting nozzles 13 mounted to the hover skirts 2, respectively; and an air supply source that supplies air to the hover skirts and the air jetting nozzles, wherein the suction apparatus body 1 floats on a surface of the residual sludge liquid (L) by supplying the air from the air supply source to the hover skirts, and moves on the surface of the residual sludge liquid (L) by jetting the air from the air supply source through the air jetting nozzles 13.
    • 提供了一种残留的放射性污泥液体抽吸装置,其能够安全地且可靠地吸入残留在污泥储罐中的放射性污泥液体,而不用担心在污泥储存罐中剩余的少量污泥液体不会暴露在辐射下 转移到另一个坦克。 吸入装置是在残留在污泥容纳槽T1中的残留污泥液体(L)被转移时用于吸附残留放射性污泥液体(L)的残留放射性污泥液体抽吸装置,具备:吸引装置主体1 ; 安装在吸引装置主体1上的三个悬停裙2; 吸入头8,安装在吸引装置本体1上,构成为吸收残留污泥液体(L)。 分别安装在悬停裙2上的喷气喷嘴13; 以及将空气供给到悬浮裙部和空气喷射喷嘴的空气供给源,其中,通过将空气从空气供给源供给到悬停裙部,抽吸装置主体1浮动在残留污泥液体(L)的表面上, 并且通过空气喷射喷嘴13从空气供给源喷射空气而在残留污泥液体(L)的表面上移动。
