An explosion rocked the Electricite de France SA (EDF) nuclear waste treatment plant in southern France Monday, killing one and leaving four others injured, one with serious burns.  The blast occurred at an oven in the Centraco waste processing facility.  Despite the injuries, apparently no radiation is reported to have leaked as a result of the explosion.

The plant that experienced the blast is used by EDF to treat low-level radioactive waste.  The fire was brought under control within one hour of the initial blast, however, the loss of a life and other injuries resulted.  The cause of the blast is still unknown.

Unfortunately for the company, the explosion has occurred in conjunction with safety checks at the country’s numerous nuclear installations by France’s nuclear regulator.  The tests are designed to determine whether nuclear facilities are able to withstand floods, earthquakes, and loss of power and cooling.  While no reactor is present at the site of the explosion, facilities like Centraco are still subject to inspection by regulatory bodies.

A statement released by the French Nuclear Safety Authority said, "According to initial information, the explosion happened in an oven used to melt radioactive metallic waste of little and very little radioactivity.  There have been no leaks outside of the site."

Those injured were not contaminated by radiation.

Of all the countries in the world currently using nuclear power, France is by far the most dependent on it for energy countrywide.  With 58 nuclear reactors, the nation is a major exporter of nuclear energy and treats nuclear waste from around the world.

Tesla records $1.1bn quarterly profit

Spurred by record levels of global demand and new inflection point for electric vehicles, Tesla's production ran close to full capacity in Q2

Tesla recorded $1.1 billion net income in the second quarter, for the first time in its history, overcoming semiconductor chip shortages and other supply chain challenges.

Spurred by record levels of global demand and 'never-before-seen inflection point' for electric vehicles, production ran close to full capacity, and a quarterly highlight was the launch of the Tesla Vision. Total revenues were just under $12 billion and year-on-year production increased from 180,338 models to 206,421.

Technology will continue to be key to the carmaker's future. "Solving full autonomy is a difficult engineering challenge in which we continue to believe can only be solved through the collection of large, real-world datasets and cutting-edge AI," it said.

Progress is being made on the industrialisation of the Cybertruck, which is earmarked for production at Austin. The removal of radar, which is enabled by its collection of a vast dataset of corner cases, allows Tesla to focus on vision and increase the pace of improvement - the first customers have downloaded FSD V9 Beta this month.


Geographic production breakdowns were as follows:

  • US California and Texas production ramp of Model S progressed and majority of all Model 3/Y was delivered, and Texas Gigafactory (pictured below) continues to progress
  • Shanghai production remained strong despite 'minor' supply chain challenges and Tesla has completed the transition of Gigafactory Shanghai as the primary vehicle export hub
  • Europe Berlin-Brandenburg demand (main photo) remains well above supply, resulting in growing wait times for delivery, and new equipment and testing tools are being introduced, with growing import volumes in the interim
  • The company is "on track" to build its first Model Y vehicles in Berlin and Austin this year but pressures on batteries and supply chains means the Semi truck program has been pushed back to 2022

Tesla said it has successfully validated performance and lifetime of its 4680 battery cells produced at its Kato facility in California but "we still have work ahead of us" before it can achieve volume production. Energy storage deployments more than tripled, driven mainly by several Megapack projects, although energy storage production continues to be held back by supply chain challenges, given its long backlog. Solar deployments reached 85MW in Q2, a triple jump on Q2 2020.
