A tool is provided for assisting the loading of nuclear fuel assemblies inside a reactor core. The assemblies have a prismatic shape and square cross-section, and are positioned on a plurality of adjacent locations, likewise with square cross-section, each comprising positioning blocks and orifices for circulating a liquid coolant and in particular water. The tool comprises an actuator which, in retracted positions, has a square requirement less than that of a fuel assembly. The actuator is provided with means for acting at the intermediate fuel assemblies and/or at the intermediate baffles of the reactor vessel of the location concerned at which it is being introduced. The actuator is provided with gripping means designed to cooperate with the grab of a handling mast enabling its insertion at the location concerned.
