This Sunday, EDF's nuclear reactor fleet reached a record level of unavailability, mainly due to extreme heat and drought conditions. Several reactors were forced to reduce or halt their production due to environmental constraints, disrupting electricity supply.

According to sources, these environmental constraints relate to external causes affecting the reactors' ability to operate at full capacity. The implications of this situation for the electricity grid and supply remain to be assessed.
