Největší francouzská jaderná elektrárna Gravelines musela kvůli přemnoženým medúzám v moři odstavit polovinu ze svých šesti bloků. Oznámil to v úterý provozovatel zařízení společnost EDF. Produkci dalších bloků pak bylo nutné snížit na polovinu. Kvůli vysokým teplotám a suchu musela Francie odstavit či snížit výkon bloků i v dalších jaderných elektrárnách.

Obrovské hejno medúz v pondělí dočasně vyřadilo z provozu tři reaktory jaderné elektrárny Gravelines na severu Francie. Medúzy se dostaly k systému, který nasává mořskou vodu potřebnou k chlazení elektrárny, a začaly ucpávat filtry. Provozovatel, státní energetická společnost EDF, proto reaktory preventivně odstavila, informovala agentura Reuters.
