Claims

[Scope of utility model registration request]

(1) The horizontal arm has a vertical shaft hole in the center, and vertical positioning pins are installed downward from the left and right sides of the hole, and the lower end of the operating shaft is inserted into the vertical shaft hole so that it can move up and down. has a gripping part that can be freely engaged and detached from the clamp part of the upper nozzle of the nuclear fuel assembly for a pressurized wooden reactor by remote control of the operating shaft, and can be freely placed on the pad part of the upper nozzle. is fixedly installed, each vertical positioning pin of the horizontal arm is inserted through the vertical indoor hole of the base, and further downward from the base, the vertical positioning pin is inserted into the S hole of the upper nozzle. Nuclear fuel for a pressurized wooden reactor is provided with a vertical guide pin that protrudes and can freely penetrate into a simple pipe hole drilled in the mounting plate of the nozzle when the operating shaft is lowered after the nozzle has been placed. Jig for disassembling and assembling aggregates.

(2) A nuclear fuel assembly for a pressurized wooden reactor according to claim 1 of the utility model registration claim, wherein the longitudinal guide pins are provided in a protruding manner corresponding to all or some of the simple pipe holes. Jig for disassembling and assembling.
