Radioactive waste management

Radioactive waste resulting from the previous activity of the plant, and those resulting from decommissioning activities, are stored in the interim storage facilities in the site.

Upon completion of the gradual transfer of the waste to National Repository, all the interim facilities will be dismantled.

According to the Ministerial Decree of 7 August 2015, at the end of 2020, the amount of radioactive waste in Garigliano site is equal to 2,905 cubic metres.

The amount can vary based on the year, the continuation of safe maintenance and decommissioning activities and the conditioning techniques for previous waste.

In Garigliano Plant there are two interim storage facilities for the radioactive waste.

In particular, between 2007 and 2013, the building that previously housed the emergency diesel generator was restored and adapted in an interim storage facility; moreover, a new interim facility, called D1, was built for the safe management of previous radioactive waste and those resulting from the safe maintenance and decommissioning activities of the plant.

In 2013, after the completion of the authorisation procedures on behalf of Ispra, conditioned radioactive waste and super-compacted asbestos drums were transferred from the turbine building to the two interim facilities.
