Abstract (en)
[origin: US4984598A] A system for working on the water box of a nuclear power station steam generator comprises a first member having a substantially elongate shape and forming a first arm of the system and a second member having a substantially elongate shape. The second member is articulated at one end to one end of the first member. The combination of the first and second arms is adapted to be inserted into the water box of the steam generator through the manhole. The second member may be moved to a deployed position relative to the first member. A vehicle mounted on and mobile relative to the second arm is used to scan and decontaminate the various parts of the water box of the steam generator. A working device such as a decontamination device is carried by the vehicle. It is able to reach a plurality of areas on the internal surface of the steam generator. A remote control system is provided for the vehicle and the working device.
