Management and Disposal of Spent Nuclear Fuel

Practices

  • NPP SNF is stored onsite in pools for 1-5 years before being transferred to interim wet storage onsite
  • In 2016 construction of a DGR began at the selected Olkiluoto nuclear site
  • Investigations at the ONKALO underground rock characterization facility have been ongoing since construction began in 2004
  • Disposal is intended to occur from the 2020s to the 2120s before closure
  • The VTT Technical Research Centre, government organizations, universities, and operators conducted a €16 million project from 2015-2018 examining nuclear waste technologies, long-term safety, and “nuclear waste management and society”

Obligations

  • Finland signed the Joint Convention in 1997 and accepted in 2000
  • Finland acceded to Euratom’s safeguards agreement (INFCIRC/193) in 1995, and the additional protocol entered into force in 2004
  • Finland has a “once-through” fuel cycle policy with no reprocessing; spent fuel is considered a form of waste
  • Funds for waste research are allocated in proportion to State Nuclear Waste Management Fund targets
  • According to the 1978 decision of the Finnish Government, each producer of nuclear waste – in practice the nuclear power companies – is responsible for the management of spent fuel
