成の燃料中継装置が提案されている。 Therefore, in order to perform fuel exchange smoothly, quickly and efficiently, and to make the fuel exchange equipment more compact and high-performance, the present inventors developed a fuel tank installed close to the reactor vessel and the ex-core fuel storage tank. A ramp extending into the fuel transfer chamber is opened, a movable truck swingably disposed inside the fuel transfer chamber is connected to each ramp by swinging, and a fuel bucket containing fuel is transported through the movable truck. A fuel relay device configured to perform relay movement between the two slopes has been proposed.

通となるため、燃料移送室を開放して作業員が直
接に作業することは困難である。 In this type of equipment, fuel buckets move in and out of the fuel transfer chamber, causing radioactive sodium to accumulate and the internal atmosphere to be shared with the radioactive reactor cover gas. Difficult to work with.
従つて、燃料移送室内の機器の保守、補修を必
要とする場合は、これ等を室外に取り出す必要が
ある。 Therefore, when maintenance or repair of equipment in the fuel transfer chamber is required, it is necessary to take these items out of the room.

一方、燃料移送室内設備のうち、最も保守、補
修頻度の高いものは燃料バケツトである。 On the other hand, among the indoor fuel transfer equipment, the one that requires the most frequent maintenance and repair is the fuel bucket.
そこで、この燃料バケツトのみを取り出すこと
が考えられるが、燃料バケツトのみの取出しでは
これを連結した索条との結合解離を要し、この作
業が面倒となる。 Therefore, it is conceivable to take out only the fuel bucket, but in order to take out only the fuel bucket, it is necessary to disconnect the fuel bucket from the cable to which it is connected, and this operation becomes troublesome.
