Renovation of the 4 900 MW PWR overhead cranes in the machine room - without stopping production.

A complete worksite


As part of the process of extending the lifespan of its nuclear power plants, EDF needs to change the stators weighing around 300 tonnes by operating the 2 heavy cranes in the engine room in synchronised mode.

To achieve this, EDF asked COMETE-J.Paris to carry out the complete renovation of the 4 heavy cranes in the engine rooms at the Bugey power plant.
