Package Type

Designed as a self shielded storage and disposal container Type B quantities of Intermediate Level Waste (ILW).


To be transported within a Type B Transport overpack.


The 3m3 SAFSTORE DRUM is designed as a robust shielded waste package manufactured form ductile cast iron providing both shielding and enhanced package performance with minimum reliance on the wasteform contribution.

The 3m3 SAFSTORE DRUM is designed to be compatible with the container only aspects and weight limits specified within RWM Waste Package Specification WPS/320/04 for 3 cubic metre drum 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).

For transport to a GDF it is intended to overpack 3m3 SAFSTORE DRUM within a Type B transport container such as the RWM Standard Waste Transport Container (SWTC).

The 3m3 SAFSTORE DRUM 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 standard shielding thicknesses of 100mm, 150mm and 200mm (other thicknesses can be provided on request).

  • Opening is circular
  • Closure via a ductile cast iron shield lid with bolted closure
  • A filtered vent is provided to allow gas release but prevent particulate escape
  • A process port is provided on the shield lid

Approved Contents

A wide range of solid ILW materials (including unconditioned wastes) can be accommodated. Various wall thicknesses of the ductile cast iron are provided to allow shielding to be optimised against maximising cavity volume for different activity contents and optimising filled mass.

Modes of Transport

By road, rail or sea.
