Sweden is at the international forefront of work on a final repository for spent nuclear fuel. All of the world’s nuclear power producers, however, have this issue on their agendas and are seeking solutions. A fundamental international principle is that each country is responsible for its own nuclear waste. At the same time cross-border cooperation and information exchange between different countries is of considerable value.
Not alone
In May of this year, SKB gathered representatives from many of the countries that produce nuclear waste for an international information exchange. The President of SKB, Claes Thegerström, stated then that international dialogue is important for Sweden too.
“We learn from the differences in other countries’ programmes and from the experts behind these programmes. It is also reassuring to see that other countries have chosen the same path as we. We may by slightly ahead, but we’re not alone,” said Claes Thegerström.
Rules and control
International cooperation also includes regulating and supervising international nuclear waste management. Several international organisations, including the UN Atomic Energy Commission, work to check or support management of radioactive waste. There is also an international agreement, which Sweden and other countries are committed to follow.
Consensus on geological repository
The nuclear waste producers of the world agree that a final repository in some sort of geological formation is the best alternative. Sweden has stabile bedrock which enables a deep repository. France is planning a repository in clay and Germany’s principal alternative to date has been a final repository in salt formations. The fact that different countries have different types of spent nuclear fuel is another reason for variation in the requirements for a final repository.
Political opinion
Work with nuclear waste programmes, not the least to locate a site for a final repository, has been complicated by political resistance and local opinion.
“The technology is difficult, but public acceptance and support afford even greater challenges,” says Saida Laârouchi Engström who is responsible for environmental impact assessment and public information at SKB.
