Radioactive waste management

​​Radioactive waste resulting both from previous plant operations, and from decommissioning activities, are stored in the interim storage facilities of the site. Upon completion of the gradual transfer of the waste to National Repository, all the interim storage facilities will be demolished.

At the end of 2020, the volume of (solid and liquid) radioactive waste, classified according to the Decree of 7 August 2015, in the plant of Casaccia amounts to 463 cubic metres.
The volume may vary based on the year, the continuation of safe maintenance and decommissioning activities and the conditioning techniques for previous waste.

​​Almost all radioactive waste is in solid form (less than 1% is liquid).

The radioactive waste currently located on site, resulted from previous activity of the plant and from decommissioning activities, is temporary stored in the premises of the Plutonium Plant, in the OPEC-1 and OPEC-2 interim storage facilities.
