Inside information from China could sink the French nuclear flagship EPR  https://www.ausgestrahlt.de/blog/2021/12/09/insider-infos-aus-china-k%C3%B6nnen-franz%C3%B6sisches-atomflaggschiff-epr-versenken/ 09.12.2021 | Eva Stegen    In 1989, in response to Chernobyl, development of a third generation reactor began. The European pressurized water reactor EPR has not yet generated a kilowatt hour in Europe. Despite multiple disasters, no one pulled the rip cord. Now a whistleblower reveals a system error that should be the end of the EPR.

Some people either have nerves of wire, no self-esteem or the deep certainty that any nonsense they utter will be whipped into all media via the international press agencies, just as if one did not have to check a completely absurd announcement at least once. But it is so, the French emperor is naked. He just yelled out to the press that he wanted to have six more reactor construction sites for the fiasco flagship EPR (European pressurized water reactor) when a whistleblower tore the last scrap of material off his body. It was a French nuclear engineer who had an in-depth look at the EPR reactors in Taishan, China. They are the only two – out of 200 announced – that ever went online.

There it was just ………

However, one of the two is offline again after just 2.5 years of operation. With an unknown outcome. Evidence is growing that a design flaw affecting the entire EPR series has led to Taishan 1 being switched off. The whistleblower gave the radiation research institute ‘CRIIRAD’ important detailed technical information from Taishan. CRIIRAD, in turn, put a series of questions to the French nuclear regulator, ‘Autorité de Sûreté Nucléaire’, ASN.

The silence of those who knew it

A copy was sent to the news agency ‘AFP’, but miraculously the horror news did not spread as rapidly as Macron’s ludicrous announcement to sink further billions in further ‘EPR’ flop construction sites. With every additional day on which neither the operator nor the nuclear regulatory authority deny ‘ASN’, this hypothesis of the design flaw, which affects all ‘EPR’, becomes more important.

In June 2021, a CNN report from Taishan, China caused a stir. There was talk of an “imminent radiological threat” in a letter from the French consortium partner “Framatome” to the US Department of Energy, which “CNN” has received. The Chinese security authorities were accused of having raised the radiation limit values for the outside area around the nuclear power plant in order to circumvent the shutdown of the defective reactor block.

Where do the radioactive gases come from?

As early as October 2020, defects were found on the cladding tubes of some fuel elements, which led to the escape of radioactive gases in the reactor pressure vessel. Despite the radiological risks for workers and residents, the nuclear power plant continued to operate. First of all, according to Bruno Chareyron from ‘CRIIRAD’. This duct damage is quite normal, something like that happens. In fact, however, the degree of damage to the cladding tubes and the gas leaks in the reactor have steadily worsened since it was loaded with fuel in autumn 2020.

The operators have asked the authorities to increase the limit value, above which the reactor must be shut down. The authorities would have doubled the value , but as the contamination continued to rise, the new warning threshold was exceeded at the end of May 2021. This continued until the shutdown on July 30, 2021. In August, the fuel rods began unloading. Nobody knows when or whether the reactor can ever start again.

Thanks to the whistleblower’s insider knowledge, ‘CRIIRAD’ is now able to track down the causes of the defective ducts, which the investigative satirical magazine ‘le Canard enchaîné’ described as “knots in the pipelines”. The cameras that the Chinese had brought into the heart of the EPR, in the reactor pressure vessel, were supposed to check the thesis that the zirconium cladding tubes that protect the uranium fuel rods are unusually corroded.

In addition to the risk of pipe rupture in the primary circuit, there is also the risk that the grids, which are intended to hold the fuel elements in position in the reactor pressure vessel, are damaged by the vibrations. If this structure is weakened , Chareyron explained , it is conceivable that in the event of an earthquake the clusters of fuel and control rods would swing against the inner walls of the container. A deformation induced in this way could mean that the control rods, which are actually supposed to brake the nuclear chain reaction, cannot retract.

Bad Vibrations from Olkiluoto and the scandal forge Le Creusot

As early as 2018, the Finnish electricity supplier ‘TVO’ and the Finnish safety authority ‘STUK’ reported that during tests on the Olkiluoto EPR permanent construction site, vibrations had occurred in the primary circuit on the reactor pressure vessel .

But as early as 2007/08 hydraulic model tests at the scandal-shrouded nuclear component manufacturer in Le Creusot brought the vibration problem to light. That is why ‘CRIIRAD’ asks the nuclear supervisory authority about the failed attempt to reduce the flow of water with the help of a baffle that was attached under the reactor core in order to influence the hydraulics and thus the vibrations. The vibration problem is obviously inherent in the system and affects not only the Taishan blocks but also Olkiluoto, Flamanville and Hinkley Point C. In short, all Generation 3 reactors that were once touted as “inherently safe”.

Corecatcher not catchy

In addition to carbon-brittle forging errors, messed up welds and inferior concrete, there are also vibrations of the artfully knotted pipeline design. The once-praised core catcher, which was supposed to catch a melted reactor core, apparently also gives the engineers a headache. If a large fragment of the container were to block the slide to the catcher, the corium would not flow into the catcher, according to the confidential account. But the naked Emperor Macron never tires of loudly proclaiming his atomic illusions. If the idea of the third generation of EPR reactors, which incidentally dates back to 1989, doesn’t work, you can tell the same nonsense again. Simply use the same “climate saver” texts again, just replace generation 3 and EPR with generation 4 and SMR. Apparently, the president is sure that the news agencies and the associated copy-paste editorial offices are already creating the appropriate mental cinema for EU citizens. Because he wants taxonomy money from them, for even more atomic illusions.
