Flamanville EPR Reactor Reconnected to Grid Two Days Ahead of Schedule

The long-delayed nuclear reactor resumed operations on April 19 at 90 MW output, with full capacity expected by summer 2025.

Overview

  • The Flamanville EPR reactor, offline since February 15 due to technical issues, was reconnected to the grid on April 19, 2025.
  • The restart occurred two days earlier than the revised schedule, following multiple delays for maintenance and testing.
  • Initial power output is 90 MW, with power variation tests planned through the coming week to ensure stability and safety.
  • EDF confirmed its timeline to progressively ramp up the reactor to full capacity of 1,620 MW by summer 2025.
  • This marks a key milestone for France's first new reactor in over a decade, part of its broader nuclear energy strategy.
