摘要： The proposed nuclear reactor comprises fuel assemblies whose heads are shaped as prisms and provided with an internal hollow for the working member of the gripping means to grip and handle the fuel assembly. The gripping means is accommodated in a guide member of a refuelling device having an end face shaped as a truncated cone whose vertex is directed towards the head of a fuel assembly being handled. Recesses are provided in the end faces of the fuel assembly heads. The number of recesses is equal to that of fuel assemblies adjacent to the fuel assembly being handled. The recesses are arranged symmetrically with respect to the face edges of the fuel assembly heads. The sides of the recesses next to the recess which is adjacent to the recess of the fuel assembly being handled and facing the fuel assembly being handled all form parts of the surface of a truncated cone whose axis is matched with the longitudinal axis of the fuel assembly being handled. The diameter of the lesser base of the truncated cone of the guide member is greater than the diameter of the lesser base of the truncated cone partially formed by the sides of the recesses facing the fuel assembly being handled, but less than the diameter of its greater base.
