The Swedish government’s decision to delay approval on a permanent repository for used nuclear fuel is risky and could have consequences that are as yet unclear, Johan Dasht, chief executive officer of nuclear fuel management company SKB, said.

In a statement posted online, Mr Dasht said the government had the opportunity to make a decision on SKB’s complete final repository system application but chose to extract and only deal with the section concerning licensing of increased storage capacity in the interim storage facility Clab in Oskarshamn.
