The Swedish government has commissioned an investigation to evaluate the state's role in financing new nuclear power.
The government had previously allocated 400 billion SEK in state credit guarantees for the construction of new nuclear power plants.
However, according to the Finance Market Minister, Niklas Wykman, these guarantees are insufficient and additional measures are needed.
The investigation will also examine risk-sharing models used by other countries and is expected to be completed by next year.
This news comes after a previous stance by the government that no money would be provided for new nuclear power.
The change in stance came after Finance Minister Elisabeth Svantesson and Vattenfall's CEO Anna Borg visited the British nuclear power construction site, Hinkley Point C, to understand the practicalities of building new nuclear power.
