"Tarn-et-Garonne: The director of the Golfech nuclear power plant summoned to explain the dysfunctions
20 Minutes with AFP

SECURITY - A rare occurrence, the director of the Golfech nuclear power plant in Tarn-et-Garonne has been summoned to the Nuclear Safety Authority to explain himself about malfunctions

This "summons", made public, is not customary for the Nuclear Safety Authority (ASN), responsible for monitoring French power plants. However, it was by press release that it announced Friday that it had summoned the director of the Golfech nuclear power plant in Tarn-et-Garonne to explain the malfunctions noted on the site.

The interview with the ASN director general took place on January 27. The Golfech manager was criticized for "deficiencies in the implementation of reactor operating operations and a lack of systemic rigor in the recording and traceability of activities relating to the maintenance of installations".


This rise of suspenders follows the control visit carried out on the site in October 2019, a few days after a classified incident of level 2 (on a scale which counts 7).

Too superficial an analysis of incidents ... "

Nuclear: decommissioning authorized for the Eurodif plant (Tricastin)

AFP published on 17 Feb 2020

The Orano group announced Monday that it has received authorization to dismantle the old Eurodif uranium enrichment plant on the Tricastin site (Drôme), a project which should take around 30 years.

These operations, authorized by a decree published in the Official Journal, will consist in deconstructing all of the industrial equipment. The decree specifies that they must be completed no later than December 31, 2051.

The operation of this plant, baptized "Georges-Besse" after its founder, ceased in 2012. In 33 years, it has provided, according to its operator, up to "a quarter of the world capacity" of uranium. enriched, by the so-called gaseous diffusion method.

"Dismantling is a real industrial operation, conditioned here by the gigantism of the installation and its equipment", explains Philippe Horteur, director of end-of-cycle operations at the Orano Tricastin site, quoted in the press release.

It will include the 1.400 floors of the diffusion cascade, which represents 160.000 tonnes of steel, 30.000 tonnes of equipment in various metals and over 1.300 kilometers of piping.

Beforehand, processing units will be set up inside the buildings to cut the equipment using hydraulic shears and crush the elements of the industrial process.

In 2013-2016, the site was notably entitled to a "rinsing" phase, in order to reduce the quantity of nuclear and chemical materials present.

Most of the radioactive waste from dismantling operations is Very Low Activity (VLL), says Orano.

As for uranium enrichment, it is continuing in two new plants known as "Georges-Besse II", this time using centrifugation technology and also located on the Orano Tricastin site.

30 years! And what cost?

I have no firm convictions on the subject of dismantling: if the 160.000 tonnes of steel can be recycled into non-radioactive products, why not. If it is to bury them in Bures, bof.

Between surface storage in drums, underground storage in Bures, or filling the plant with used concrete and covering everything with soil, what real differences? (we are talking about VLL waste)
I have a small preference for surface storage: at least we can monitor it. If it ever goes into the groundwater in the case of Bures, we are in deep shit. On the surface, at worst we move it.

In the case mentioned (GB1), there is no "landfill in Bures". It was a natural uranium enrichment plant, so no fission products present apart from the "few" natural decays of U235.

In France, the steel of nuclear installations is classified as "very low activity waste" and stored in the open air.
In Germany (also in the USA also), it is recycled and used to make VW Golf (for example), sold in France (among others), sometimes to notorious anti-nuclear companies, convinced opponents of landfilling waste . Let's take advantage of this, Germany is recycling a lot of steel at the moment.

We live in a really great time…

It's true, but "not that simple"! There is not only a regulatory and / or radiological aspect, but also an economic aspect, particularly in Germany.

A study not very young (2012), but which laid at least the main foundations:

Undoubtedly, in Germany, the concept of "radioactive" is very different from the French concept; that must be it, yes ...

And the problem is the same for concrete, and, in general, for all materials that have directly or indirectly affected nuclear power.

Well, in France, we can pay, dear, because we have class !!!

We are really living in a more than wonderful time… I'm going to buy an Audi, or a VW….

It is very likely that if we informed future buyers what steel their VW was made with, there would be fewer buyers. We live in a truly unconscious era : Cry: .
