The Ministry of the Armed Forces announced on Monday a "collaboration" with EDF in order to use the power of the two nuclear reactors at the Civaux power station to produce tritium. Tritium is a rare gas essential for deterrence weapons.

EDF is aiming for a first small-scale test during one of two shutdowns scheduled for 2025 at the power plant. The plant will not be put to use immediately, warned Etienne Dutheil, director of the nuclear production division at EDF, during a press briefing.
