Device for producing radioisotopes, especially cobalt-60, by n, gamma reaction on samples 13 which are irradiated in a fast-neutron nuclear reactor cooled by liquid metal contained in a vessel, the core of this reactor being surrounded at its periphery with an outer covering of fertile material and neutron protection assemblies, characterised in that the device 1 has the shape and the external dimensions of a protection assembly whose place it is intended to take, between the external cover and the vessel, and in that it includes, in the central part AB of its height, a tubular cylindrical ring 9 of a neutron moderator body, pierced with a central channel 11 intended to receive a removable capsule 7 containing the samples 13 to be irradiated. <IMAGE>
