Restoration and dismantling of turbine building systems

Status: in progress 
Duration: 2016-2023

The turbine building houses the systems and components that, during operation, enabled the transformation of the thermal energy produced by the nuclear reaction into electrical energy.

It therefore contains the turbo generator and all the components of the thermal cycle.

At 1.800 tonnes (400 for the rotor and alternator, 450 for the condenser and 950 corpo turbina)for the turbine housing), the plant's turbine system is the largest component of the thermal cycle. In 2016, restoration work was started on the auxiliary systems of the turbine building in preparation for the subsequent dismantling of contaminated components.

At the end of 2018, the dismantling, cutting, removal and recycling of the turbine alternator rotor and stator materials was completed. The 105 tonne cylindrical rotor, made of iron and copper, was extracted and sectioned with diamond wire into two parts. Then the alternator, made of iron, copper and plastic and weighing 296 tonnes, was removed after being cut and cleaned of any asbestos dust or debris.

Testing of the auxiliary systems of the turbine building with the Italian National Inspectorate for Nuclear Safety and Radiation Protection (ISIN) is scheduled for July 2023.

The dismantling of the turbine is expected to be completed by 2023.
