To ask the Secretary of State for the Environment what provisions have been made for the long-term management or disposal of radioactive wastes arising from the decommissioning of the Windscale piles Nos. 1 and 2, B6 and B16, at Sellafield; and if the costs are rechargeable to any Government Department.

Low-level waste arising from decommissioning of the Windscale piles is likely to be disposed of at the Drigg disposal site. Intermediate-level waste will be disposed of in United Kingdom Nirex deep repository. I understand that the costs of this work will be met by the Ministry of Defence and the Atomic Energy Authority.
