All French Nuclear Plants are Releasing Tritium

Posted: 8th December 2025

All French nuclear power plants are releasing tritium. This is the finding

of the Independent Research and Information Commission on Radioactivity
(CRIIRAD), which issued a warning on December 3rd about uncontrolled
releases. Between 2015 and 2024, 16 power plants recorded levels exceeding
10 Bq/l in groundwater, some exceeding 1,000 Bq/l such as Bugey, Gravelines
and Tricastin, the association details. The three other power plants
(Golfech, Nogent-sur-Seine, Paluel) experienced similar episodes before or
after this period, notably Nogent-sur-Seine on January 17, 2025. Criirad
emphasizes that no power plant has been able to guarantee the permanent
protection of groundwater and that any massive discharge would quickly
affect the aquatic environment. According to the Sortir du nucléaire
network , the toxicity of tritium has been underestimated, particularly
when it is absorbed by the body, where it then enters the DNA of cells.
