Abstract

1. Process for unloading and loading a nuclear reactor, according to which an irradiated control element, comprising a carrier body with a longitudinally extending neutron absorber body, is removed from the nuclear reactor and then a control element appointed for loading is replaced in the nuclear reactor, characterised in that an irradiated neutron absorber body (8a), which originates from a control element irradiated in a reference nuclear reactor, is moved, compared to its initial position in this reference nuclear reactor, into a position pivoted by 180 degrees about a transverse axis (15) and/or a position turned about a longitudinal axis (14) and/or another place outside the reference nuclear reactor relative to the carrier body of this irradiated control element, in the control element appointed for loading, and is arranged on its carrier body, and in that this control element appointed for loading is inserted into the nuclear reactor in such a way that the neutron absorber body (8a) is in the position pivoted about the transverse axis (15) relative to its initial position in the reference nuclear reactor, or respectively the position turned about the longitudinal axis (14), or respectively the other place outside the reference nuclear reactor relative to the carrier body of the irradiated control element.
