Section: abstract

Apparatus and process for supervising and controlling the operations of loading and unloading of fuel of a nuclear reactor comprising an information processor 30 formed from several units. A treatment unit 31 receives control signals giving notably the position, the speed, the load of machines 7 and 16 operating the loadings and unloadings of groups in the core 2, the reactor pool 3, and the spent fuel pit 14. A programmable unit 34 furnishes command signals, previously recorded, representing the loading sequence. The command and control signals are treated in a central calculating unit 35 which, while considering the information furnished by the permanent memory unit 32 and by the temporary memory unit 33 gives on one hand the coordinates of all sites for the groups, and on the other hand the coordinates of the places of the movable elements as well as the identification marks and positions of each group, compares the different signals received, and according to their coincidence, authorizes or arrests the directed movement. The temporary memory unit 33 saves the last position acquired while erasing the previously occupied positions, while the control box 37 records all of the movements executed.
