Claims

[Scope of utility model registration request]

A communication pipe 4 is removably attached between an upper guide pipe insertion hole formed in a rotary plug 2 serving as the upper cover of the reactor vessel 1 and an upper guide pipe handling machine main body 3 located above the rotary plug 2. At the same time, the inner diameter of the communication pipe 4 is made larger than the outer diameter of the upper guide pipe 5, and the cooling gas pipe 6 is installed so that the inert gas for cooling the guide pipe flows continuously through the communication pipe 4. Upper guide pipe handling machine of the reactor control rod drive mechanism connected to the communication pipe 4.
