The pictures show the part of the equipment, which works in the main circulating pump (MCP) housing.  The upper figure shows the decontaminating head standing on a track of the model of the housing.

The robot is controlled by a PC-installed program, by the help of which the cleaning heads automatically follow the accessible internal surface of the MCP housing, cleaning it electrochemically. 92% of the total 8 m² internal surface can be cleaned automatically, except for the chamferred edges. Decontamination of one pump housing can be completed winthin one shift.

The decontamination process can be monitored using two video cameras mounted on the equipment (bottom figure).
