The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

The tribulations of France’s Flamanville nuclear reactor.

“EDF is struggling to sleep off its nuclear power”. Here is the title
at the top of page 3 of the Chained Duck of this Wednesday, January 19,
2022. Is this a new article following the announcement, a week ago, of a
delay and an additional cost of 300 million euros for the site of the
future Flamanville EPR reactor?

No, there is no question of welding rework
operations taking longer than expected. “The energy company must face a
formidable puzzle encountered on the reactor vessel, where nuclear fission
takes place”, announces from the outset journalist Hervé Liffran.

The concern was flushed out followingan incident on the other side of the
world, in China. The Taishan nuclear power plant, with the world’s first
EPR reactor in service, was shut down on July 30, 2021, after damaged fuel
rods caused a buildup of radioactive noble gases in the reactor’s primary
circuit. In November, we learned thata fault in the design of the tank
would be the cause of the problem.

It was a whistleblower working in thenuclear industry who informed, on condition of anonymity, the Commission for Independent Research and Information on Radioactivity (Criirad), which
in turn alerted the Authority. Nuclear Safety Authority (ASN) by post. And
the shutdown of the plant was ordered “because of the presence of
numerous and dangerous debris in the water of the primary circuit bathing
the heart of the reactor”.

Questioned this Wednesday on this subject, the
Deputy Director General of the Nuclear Safety Authority, Julien Collet,
replied: “ASN has asked EDF to take account of experience feedback from
this event at EPR Taishan 1 prior to the commissioning of the Flamanville
EPR reactor. EDF will either have to demonstrate that the Flamanville EPR
is not concerned, or propose measures to prevent fuel degradation.
