Government policy on all nuclear waste stored at Sellafield is that it should be safely and securely managed to ensure it poses no threat to Ireland and its environment. Regarding the mixing of different types of waste currently stored at Sellafield, whether generated there or elsewhere, my Department has no information that there is any plan to mix different types of waste, and there are no figures currently available to us regarding the sources and the break down of waste at Sellafield between first generation and second generation waste.
Dounreay is located on the north coast of Scotland, and was established on a former naval base as the centre for UK fast reactor research. It is now engaged on a major decommissioning and site restoration programme to deal with the legacy of past operations. It is estimated by the UK Government that the environmental restoration of Dounreay will involve the investment of £4.5 billion over the next 50-60 years.
