Casks for low and intermediate-level radioactive waste
Prior to interim storage, low and intermediate-level radioactive waste is ‘conditioned’, meaning it is specially treated, processed and packaged. Depending on the consistency, size and nature of the waste, various conditioning processes are used:
Liquid waste is evaporated or cemented, whereas solid waste is crushed, dried, incinerated, melted, compacted or cemented.
Once the waste has been processed, for example, into briquettes or concentrates, it is packed in approved and standardised casks.
There are three basic types of casks for this:
- Cylindrical concrete casks
- Cylindrical cast iron casks
- Standard casks
All these casks have successfully completed an extensive test programme at the Federal Institute for Materials Research and Testing (BAM) and have been approved in accordance with the regulations for transport and interim storage. This guarantees that the legal requirements of the Radiation Protection Ordinance (German version only) are reliably complied with.
