Sweden is “decades ahead of the UK” in terms of handling nuclear waste, according to a report in Britain’s Independent on Sunday.
At the Oskarshamn site, the nuclear waste joint venture SKB has built the world’s largest underground laboratory to test conditions for the permanent storage of nuclear waste. Named the Hard Rock Laboratory (no relation to the celebrity hamburger chain), it meanders 450 metres underground. Branching off from the main tunnel, which is large enough to park a coach, dozens of horizontal chambers have been excavated. Here scientists experiment with different types of rock to discover how best to bury copper-encased, spent-fuel canisters.
