Overview
- The ASNR authorization lets EDF continue raising output beyond 80% and proceed toward maximum power while completing the start-up program.
- EDF reported reaching 80% in mid-November and had targeted full power by late autumn, with final attainment yet to be confirmed.
- Regulators will keep focused inspections on each subsequent step of the power ramp-up until start-up testing concludes.
- EDF plans a 350-day shutdown from 26 September 2026 to replace the reactor vessel cover at the regulator’s request.
- Project costs have risen from an initial €3.3 billion to about €23.7 billion in 2023 terms, and the validated maximum output remains under review between 1,585 MW and a hoped-for 1,620 MW depending on conditions.
