6. The new approach to the decommissioning The new inputs given to SOGIN by the Italian Government are :The new inputs given to SOGIN by the Italian Government are : -condition all the radioactive waste existing on the NPPs within the year 2010 -release all the nuclear sites – free of radiological constraints - by 2020 The last task is conditioned by availability of the national waste repository from the year 2009The last task is conditioned by availability of the national waste repository from the year 2009

8. Three main steps of the new decommissioning strategy 2000 - 2005 (a) 2005 - 2008 (b) 2009 – 2020 (c) (b)Preparatory activities for final dismantling. Waste produced can be managed on site (c)Nuclear island dismantling (a)Dismantling of BOP and Conventional Building. (Activities compatible with both SAFESTORE and DECON strategies).
