Safely disposing of waste remains one of the key challenges for the nuclear power industry. We explore the benefits of dry storage with French operator Orano’s storage casks and canister-based systems and compare the benefits of the two interim methods – “wet” and “dry” storage. Entirely relying on wet spent fuel storage as an intermediate step in tackling used nuclear fuel is widely practised around the world, including in the UK, with countries implementing a “closed fuel cycle” strategy, which includes reprocessing and recycling in wet conditions. Some countries, such as Sweden and Finland, store all their spent fuel inventory in wet conditions until spent fuel meets the requirements for final disposal. Others, like the US, Canada, and Germany move the spent fuel to dry conditions after the initial wet cooling period. While wet storage has proven its value over time, the newer technique, dry storage, has recently gained more popularity in some regions, despite still needing to prove its strengths as a safe and reliable storage method worldwide.
