How does France process and dispose of nuclear waste?
France is one of the world's leading producers of nuclear energy, and it has developed a comprehensive system for processing and disposing of nuclear waste. The French approach is based on the principle of "closed fuel cycle", which means that the waste is reprocessed to recover reusable materials, and the remaining waste is then disposed of in deep geological repositories.
The first step in the French nuclear waste management process is reprocessing. Reprocessing involves chemically separating the reusable materials from the waste. The reusable materials include uranium and plutonium, which can be used to make new nuclear fuel. The remaining waste, which is mostly radioactive fission products, is then vitrified. Vitrification is a process in which the waste is mixed with glass and heated until it melts. The molten glass is then poured into stainless steel containers and allowed to cool. The vitrified waste is then ready for disposal.
The French government has designated two deep geological repositories for the disposal of nuclear waste. The repositories are located at Bure and Cigéo. The Bure repository is currently under construction, and it is expected to begin receiving waste in 2025. The Cigéo repository is still in the planning stages, and it is not expected to begin receiving waste until 2035.
The French nuclear waste management system is one of the most comprehensive and safest in the world. It is based on the principle of "closed fuel cycle", which minimizes the amount of waste that needs to be disposed of. The waste that is disposed of is vitrified, which makes it very stable and resistant to leaching. The repositories are located in deep geological formations, which provide a natural barrier to the release of radioactivity.
