8 Final Decommissioning Plan (FDP) was developed by I in 2004 and approved by the Ministry of Economy in The FDP pointed out the Immediate Dismantling Strategy to reach the brown field state by the end

9 Reduce nuclear risk: final shutdown of the Units defuel reactors and pools and provide safe interim storage for spent fuel Reduce environmental risks: upgrade of existing waste storages retrieval, conditioning and safe storage/disposal of stored operational waste Proceed with D&D according Immediate Dismantling Strategy: dismantling must be justified considering fuel safety D&D can only take place if waste management routes and interim storage/disposal facilities are available 9

10 Opening waste management routes (Design & construction) ISFSF SWMSF Landfill Facility Near Surface Repository Unit 1 activities Operation Fuel in core Fuel in pools Fuel fully removed Post-operation Dismantling & Decontamination Unit 2 activities Operation Fuel in core Fuel in pools Fuel fully removed Post-operation Dismantling & Decontamination General site activities Site Operation & Maintenance D&D Demolition

11 Units Final Shutdown Unit 1 December 2004 Unit 2 December 2009 Reactors defueling Unit 1 December 2009 Unit 2 February 2012 Pools defueling Unit 1 August 2015 Unit 2 January 2016 Start D&D activities Unit Unit 2 early 2012
