Fuel element changing process, for nuclear power reactor core, comprises moving fuel element group including fuel element with control element

摘要

In the fuel element changing process, a fuel element (8a) of a moved group (G1, G2, H1) includes a control element (9, 41). In a nuclear fuel element changing process, in which two or more fuel elements (8a,b; 30a,b; 40a,b) are moved together as a group (G1,G2,H1), at least one fuel element (8a) of a group is a fuel element with a control element (9,41).
