Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, how much plutonium nuclear waste has been reprocessed in the UK in each of the last 10 years; and how much of that reprocessing was done on behalf of other countries.

Spent nuclear fuel was imported into the UK, under commercial agreements, for reprocessing in the THORP plant at Sellafield.

Nuclear fuel reprocessing separates spent nuclear fuel into uranium, plutonium and highly active waste products. Separated plutonium and uranium are not categorised as nuclear waste. Highly active waste products contain only trace amounts of plutonium.

The amounts of overseas origin spent fuels reprocessed in THORP each year for the last ten years are shown in the table below.
