AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
This decree orders Électricité de France to dismantle the Fessenheim nuclear power plant, including both reactor units, fuel buildings, auxiliary nuclear buildings, conventional facilities, storage areas, electrical works, effluent tanks, and shared buildings. Some conventional and administrative buildings may stay if they support the future reuse of the site. EDF must complete the dismantling by 30 June 2048. The work is split into four phases: electromechanical dismantling, cleanup of structures and soil, demolition of buildings to at least one meter below current ground level, and site rehabilitation. EDF must monitor safety, worker radiation exposure, waste management, effluent releases, water use, and the condition of soil and subsoil, and report progress at least once a year to the local Fessenheim information and monitoring commission.
