EDF evokes a “massive and non -predictable presence” of jellyfish in the water pumping stations used to cool the reactors.
Four units of the Gravelines nuclear power plant (North) are stopped on Monday, August 11, due to the “Massive and non -predictable presence of jellyfish” In the water pumping stations used to cool reactors, EDF announced. Production units 2, 3 and 4 “Stopped automatically” Sunday evening between 11 p.m. and midnight, indicates the company on its site, “In accordance with the reactor security and protection devices”. Unit 6 then stopped, for the same reasons, this Monday morning around 6:20 am.
The power station is thus temporarily completely stopped, because its two other production units 1 and 5 are currently under maintenance. These automatic judgments “Have not had a consequence on the safety of the facilities, the safety of the staff or the environment”assures EDF on its site.
