Radioactive waste management

Radioactive waste management

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

At the end of 2023, the volume of (solid and liquid) radioactive waste, classified according to the Decree of 7 August 2015, and located in the plant of Rotondella, amounts to 3,865 cubic metres. The volume can vary based on the year, the continuation of safe maintenance and decommissioning activities and the conditioning techniques for previous waste.
