Three fishing vessels are now “constantly patrolling off the coast of the plant" to conduct "preventive fishing operations [...] 24/7,” the company added. Tuesday’s jellyfish invasion comes a the latest in a series of climate change-driven incidents that have affected French nuclear energy during a particularly infernal summer. Nuclear power plants are typically built by rivers or on coastlines so they can use nearby water sources to cool their reactors. Following last year’s incident at the plant along the North Sea, EDF installed cameras and deployed fishing boats to monitor the situation. “This only highlights that nuclear power plants are ill-equipped to deal with the consequences of climate change,” the French branch of Greenpeace said in statement.
