Robin Pagnamenta in Oskarshamn, Sweden
Inside the cavernous hall of a nuclear storage plant in southern Sweden, an 18-tonne steel canister, bristling with tiny fins to draw out excess heat, is being hauled slowly through a hatch by a crane.
Packed with highly radioactive spent nuclear fuel from a reactor north of Stockholm, the canister is being made ready for 30 years of storage in pools sunk into the bedrock. Once it cools sufficiently, it will be placed permanently in a final repository deep underground.
