The component (1) is moved in successive steps in the vertical direction, to allow cutting of an upper part (16) of the component (1), inside the cavity (pool) (4) of the reactor. First initial raising of the component (1) is carried out by exerting a thrust on the lower part (1a) of the component (1). A first modular support element (33) is introduced between the lower part of the component (1) and a fixed support (27). The component (1) is rested on the first modular support element (33). For each of the subsequent successive steps of moving the component (1), unitary lifting of the component (1) is carried out over a defined vertical distance, using second lifting means (32) bearing on the support (27). A modular support element (33, 33', 33'') is introduced between the modular element (32) by which the lifting is carried out and the fixed support (27). The component (1) is made to bear on the fixed support (27) by means of the superimposed modular elements (33, 33'). <IMAGE>
