The Gravelines nuclear power station in northern France shut down several of its reactors last weekend due to an unusual problem—pumping stations in the non-nuclear part of the facility were clogged up with the 'massive and unpredictable presence of jellyfish.'
The jellyfish were said to be amassed within the filter drums of said pumping stations, causing a potential blocking hazard and forcing three of the six reactors to shut down, with a fourth being brought offline on Monday (via The New York Times). The operator of the plant, EDF, released a statement confirming that the unwanted jellyfish "had no impact on the safety of the facilities, the safety of personnel, or the environment."
