Dismantling of the turbine and construction of the Material Management Station (MMS)

​​Status: Completed 
Period: 2004-2012

During the plant operating period, in the turbine building were located the turboalternator complex and the components of the thermal cycle (capacitor, preheater, etc.) for the production of electric energy.

Between 2004-2012, Sogin removed unnecessary systems and components, and maintained those intended for further uses, such as: ventilation, drainage and collection system and lifting devices. The works especially involved removing insulations and devices containing hazardous components (i.e., PCB or polychlorinated biphenyls). The first large component that was removed, decontaminated and dismantled, between 2004 and 2006, is the turboalternator complex (4 turbines - among which one high pressure turbine and three low pressure turbines – and an electric generator). 

Removal of the turbine of the Caorso nuclear power plant

After removing the structure, a Materials Management Facility was installed which started operating in 2009. This facility is supplied with specific instruments to carry out segmentation, radiological tests, and materials decontamination. The Facility consists of the following areas: Storage areas; Equipped areas for hot and cold cutting operations; Areas for the mechanical and chemical decontamination; Areas for the radiation monitoring of materials. The Facility has been used between 2009 and 2012 for carrying out the decontamination of the systems and components located in the turbine building, after dismantling operations. The dismantling of the turbine building resulted in 10,000 tonnes of material removed, among which 8,500 tonnes of metals and decommissioned devices and 1,000 tonnes of concrete and other construction materials. Metals are sent to recovery ​facilities after having undergone appropriate radiation monitoring.
