Copper Capsules to Store Nuclear Waste
The Swedish Nuclear Fuel and Waste Management Co. has highlighted what research they feel is needed in order to ensure that Sweden errs on the safe side of nuclear waste storage.
SKB’s report is a precursor to an application they’ll be filing in two years time, seeking permission to build a final repository for spent nuclear fuel.
The repository would be located in Oscarshamn or Forsmark, centring around copper capsules that would be protected under 500 meters of rock. But one question the company wants an answer to, is how the capsules would stand up to a future ice age.
Meanwhile, the Swedish NGO Office for Nuclear Waste Review would like to see an alternate method approved, involving holes bored to depths of five kilometres.
