“They have guys who go into the reactor to assess the status of the fuel, which is corroding badly and creating radioactive dust.

“The European Bank for Reconstruction and Development are bank-rolling the decommissioning operation, but it’s still down to scientists to understand how to safely remove the melted fuel.” “It costs a lot of money to tackle a project of this magnitude and in Ukraine they don’t have quite enough.” Claire explains. However, that also means navigating the challenges of a country with the second lowest GDP per capita in Europe. She and her team have been working with Ukrainian scientists to understand what’s going on inside the extraordinary environment of Chernobyl's stricken reactor unit 4-and how it can be decommissioned safely. Dr Claire Corkhill is a Research Fellow in the Department of Material Science and Engineering at the University of Sheffield. But Chernobyl’s end was very much unplanned. Normally this happens when the reactor has reached the end of its working life, as is the case with Magnox reactors at Sellafield on the north-west coast of the UK.

The Kazakh KazAtomProm is the largest uranium-producing company in the world, accounting for 22 percent of the global market in 2020. Globally, roughly 48,000 metric tons of uranium was produced from mines in 2020, with Kazakhstan, Australia, and Namibia as the leading uranium producers. China had the largest number of nuclear reactors planned as of 2022 and is expected to become the largest nuclear power producer in coming decades.įuel supply remains essential for any country wishing to increase their nuclear power generation output. Meanwhile, motivated by its low emission rate for electricity production, the share of nuclear in the Chinese electricity mix has more than doubled in the past decade, nearing five percent in 2020. At a whopping 70.6 percent share of nuclear in electricity generation output, France relies heavily on this energy source. The United States is the largest nuclear power generating country in the world, and also accounted for almost one-third of the world’s nuclear electricity consumption in 2020. The world's largest nuclear energy producers As of May 2022, there were 439 nuclear power reactors in operation across 33 countries. Nevertheless, worldwide nuclear power capacity is expected to continue growing in coming years, surpassing 430 gigawatts by 2035. After the 2011 nuclear disaster at Japan’s Fukushima Daiichi plant, concerns about the safety of nuclear plants regained the spotlight, and many countries – including Germany, Italy, and Switzerland – vowed to accelerate the shutdown of existing plants and stop investment in new facilities. Since then, global nuclear electricity capacity grew from just five megawatts to more than 370 gigawatts in the past decade. In 1954, the first nuclear power plant came online in the Russian city of Obninsk.
