A recently granted patent (Publication Number: US11951545B2) discloses a cask liner designed for nuclear fuel casks. The cask liner is a hollow cylinder made of a boron-containing composition, ensuring enhanced safety and efficiency in nuclear fuel storage. Importantly, the hollow cylinder is constructed without any longitudinal joints, reducing the risk of structural weaknesses or leaks. The boron-containing composition can include various materials such as boron-containing aluminum metal matrix composites or boron-containing ceramic within an aluminum or aluminum alloy base.

Furthermore, the patent also covers the method of manufacturing these innovative cask liners. The process involves isostatic pressing of a boron-containing composition to form the liner in the shape of a hollow cylinder. This method ensures the seamless construction of the liner without any longitudinal joints, crucial for maintaining the integrity of the structure. Additionally, the boron-containing composition can be produced through mechanical alloying of boron-containing powder and aluminum or aluminum alloy powder. The resulting nuclear fuel cask liner offers improved safety and reliability in the storage and transportation of nuclear fuel, meeting stringent industry standards and regulations.
