The Waste Vitrification Plant (WVP), operated by Sellafield Ltd, converts highly active liquor (HAL) from the reprocessing of spent nuclear fuel into vitrified high level waste (HLW) product for safe interim storage, and ultimate disposal in a deep geological repository. One of the important aspects to understand in relation to disposal of HLW glass is its behaviour over long timescales under aqueous conditions. To this end, a series of laboratory-based leach tests on the expected range of WVP glass compositions has been initiated and some of the preliminary results are described in this paper.
