The number of significant safety incidents affecting the reactors of the nuclear fleet has experienced a “worrying” increase since 2017, due to their aging and poor maintenance, according to a report. These incidents affect more and more frequently several units at the same time, notes the study of the association of critical nuclear scientists Global Chance, which reviewed the incidents published by the Nuclear Safety Authority (ASN) between 2010 and 2020. Many of these relate to reactor back-up diesels. Each reactor is equipped with two emergency generators, essential parts that supply power to the unit’s safety systems in the event of loss of electrical power due to an accident, such as an earthquake for example. “The most striking result is the fact that out of the 17 incidents listed by ASN [over the decade], ten concern standby diesel” which had an impact on 67 reactors in total during these years, indicate the authors of the report, the nuclear physicist and president of Global Chance, Bernard Laponche as well as the former nuclear campaigner of Greenpeace France, Jean-Luc Thierry.
