。It consists of an operation floor 5, etc., and is used for tasks such as delivering new fuel to the fuel exchange machine, attaching and detaching channel boxes for irradiated fuel, and inspecting them, and removing channel boxes for spent fuel.
上記作業のうち、新燃料の燃料取替機への受渡しは、天
井クレーンに吊り下げられ新燃料６を水中に設置された
カートに目視にて装荷作業を行っていた。この作業は、
水による光の屈折等のため。Among the above operations, the new fuel was delivered to the fuel exchange machine by visually loading the new fuel 6 onto a cart suspended from an overhead crane and placed underwater. This work is
Due to the refraction of light due to water, etc.

題がある。There are drawbacks such as it takes a lot of time to position the new fuel 6 on the cart 1 installed underwater, and it is impossible to load fuel onto the cart 1 due to poor positioning. One possible solution to the above problem is to raise the top of the cart 1 above the water surface, but since the cart 1 is in direct contact with the fuel, raising the top of the cart 1 above the water surface There is a problem of workers being exposed to radiation due to dust scattering, etc.
以下に１本発明の一実施例を第１図及び第２図により説
明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

が完了する。) In FIG. 1, the cart 1 is moved to +1.
', The new fuel 6 is raised to near the water surface by the m rotation, and then the new fuel 6 suspended by the overhead crane is moved to the top of the positioning guide 7, and the lower end of the new fuel 6 is inserted into the positioning guide 7. This completes the positioning of the cart 1 installed in the water, and then lowers the overhead crane to lower the new fuel 6. When the lower end of the new fuel 6 is seated on the lower end fuel receiver of the cart 1, loading of the new fuel 6 onto the cart 1 is completed.
