。The transfer of Takumi's BWR fuel # + coming combination is Fuzhouan 58-34
As shown in Publication No. 392, one fuel exchanger is used between the reactor core and the fuel storage pool. Therefore, in order to shorten the transfer time, it is necessary to speed up the driving speed of the fuel exchanger, but since it is a device that handles fuel and fuel, there is a limit to the speed amplifier.

把持することが容易であるが、直線状に配列されて残る
最外周の燃料果合体を２ずつ取出すことは困難である。In order to shorten the refueling time, a refueling machine has been proposed that has two hooks and grips two combined discs at one time (Japanese Patent Laid-Open No. 54-47988). but,
Depending on the arrangement of the fuel assemblies in the reactor core, a fuel converter having two hooks may not be able to hold two fuel assemblies at the same time, but may instead hold one fuel assembly. In particular, it is difficult to take out two fuel assemblies arranged at the outermost periphery of the core. This is because a fuel exchanger with two hooks can easily grasp two fuel assemblies arranged diagonally, but it is easy to grasp two fuel assemblies arranged diagonally, but the remaining outermost fuel assemblies arranged in a straight line are It is difficult to take it out.
従って、２つのフックの一方にのみ１体の燃料果合坏を
把持する状態が生じてバランスが取れないために、燃料
９．換機の走行に支障が生じる。Therefore, a situation occurs in which only one of the two hooks grips one fuel joint, making it impossible to maintain balance. The running of the switching machine will be hindered.

できる燃料交換機を提供することにある。An object of the present invention is to provide a fuel exchange machine that can easily change the number of fuel assemblies that can be gripped at one time and can perform fuel exchange smoothly and in a short time regardless of the number of fuel assemblies that can be gripped. It's about doing.

１の交換が必要となる。When a nuclear reactor is operated, the reactivity of the reactor core decreases, so spent fuel assemblies must be periodically converted into fresh fuel assemblies. The operating period of a nuclear reactor from the previous fuel exchange to the next fuel exchange is called a cycle, and the fuel assembly is replaced with a new fuel assembly at the end of each cycle. The number of fuel assemblies in the core is approximately 800 for a 1.1 million class power reactor.
It is necessary to replace 1/4 to 1/3 of the fuel assembly 1 at every regular inspection.
