Full titles differ between systems:

IPC:

Emergency protection arrangements structurally associated with the reactor > Means for effecting very rapid reduction of the reactivity factor under fault conditions, e.g. reactor fuse > by fast movement of a solid, e.g. pebbles

CPC:

Emergency protection arrangements structurally associated with the reactor (emergency cooling arrangements G21C15/18) > Means for effecting very rapid reduction of the reactivity factor under fault conditions, e.g. reactor fuse; (control elements per se G21C7/00) > by fast movement of a solid, e.g. pebbles

No child classifications to compare. This is a leaf node in both IPC and CPC.
