Sellafield: Vitrification plant melter crucibles

SMC were selected for the manufacture of the Sellafield Vitrification (VIT) Plant Melter Crucibles for over 20 years.

These are used in the long-term storage of Highly Active Liquor (HAL) produced in the VIT complex. HAL contains 99% of dissolved fission products from fuel reprocessing and is 80% supernate and 20% settled solids. SMC are the only UK approved supplier of these Crucibles which have demanding tolerances and specification requirements. The function of the plant is to safely immobilise stored and future High Level Waste (HLW) derived from the reprocessing of nuclear fuel.
