Designed as a self shielded storage, transport and disposal container for IP quantities of intermediate level waste (ILW).
Currently certified as a Type IP-2 Transport Package.
The container design has been awarded a Conceptual stage Letter of Compliance (cLoC) by Radioactive Waste Management Ltd (RWM).
The 2m half height SAFSTORE is designed as a robust shielded container for storage, transport and disposal of Intermediate Level Waste (ILW). Manufactured from ductile cast iron (DCI), the container structure provides both shielding and enhanced package performance with minimum reliance contribution from the wasteform.
The 2m half height SAFSTORE is designed to be compatible (excluding height) with the RWM Waste Package Specification WPS/350/03 for the 2 metre box waste package. It is designed to accommodate ILW that is intended for disposal within a geological disposal facility (GDF) without the need for any further packaging or treatment. It is also designed to meet RWM disposability requirements after an extended period of on-site storage. A process port is provided for any post-packaging conditioning of contents (optionally further ports can be provided if required).
The 2m half height SAFSTORE can be supplied in a range of shielding wall thicknesses; allowing optimisation against cavity volume and mass for different activity contents. Internal volume and empty weights are given for shielding thicknesses of 75mm and 120mm (other thicknesses can be provided on request).
The 2m half height SAFSTORE can be supplied with either a round lid or rectangular lid.
Illustration of Package 2m half height SAFSTORE-75
- Closure via a double lid system
- Inner ductile cast iron shield lid with bolted closure provides the same shielding as the container body
- Steel outer transport lid with verifiable seals and bolted closure
- Filtered vent in both lids to allow gas release but prevent particulate escape
- A process port is provided on the inner shield lid
As a non-fissile Type IP-2 transport package the 2m half height SAFSTORE is designed to carry solid radioactive materials that qualify as either Low Specific Activity (LSA) or Surface Contaminated Objects (SCO).
