Description

The 4m ILW BOX is large cavity stainless steel containment vessel with internal concrete shielding.

The 4m ILW BOX is designed as a self shielded storage, transport and disposal package for Intermediate Level Waste (ILW) that qualifies as either LSA or SCO.

The 4m ILW BOX is compatible with the Radioactive Waste Management Ltd specification for the
4 metre box waste package, and has been designed to accommodate ILW that is intended for disposal within a geological disposal facility.  It is also designed to meet all current transport and disposal requirements after a period of extended on-site storage.

The 4m ILW BOX can be supplied in a range of shielding wall thicknesses; allowing optimisation against cavity volume for different activity contents.
