Abstract: A decay station includes a housing comprising a radiation shielding. The housing delimits a decay conduit intended for containing the irradiation targets in the predetermined linear order. The decay conduit includes a decay conduit inlet, intended to be connected to the structure of the core of the nuclear reactor for receiving the irradiation targets therefrom; and a decay conduit outlet, intended to be connected to an irradiation target discharge system for discharging the irradiation targets from the decay station. The decay station further includes an inlet distributor, located at the decay conduit inlet, and configured for releasing only a predetermined amount of irradiation targets at a time from the decay station towards the structure of the core of the nuclear reactor. The inlet distributor is configured for releasing the irradiation targets closest to the decay conduit inlet, while retaining the remaining irradiation targets in the decay conduit.
