High Level Waste in Interim Storage Facilities: 
1,570 t HM fuel elements

For Reprocessing:
330 t HM (Russia)

Other Nuclear Waste:
2,869 m3 low and medium level waste is stored in interim storage facilities and 6,265 m3 in surface or near-surface final disposal facilities at the nuclear power plant sites. Very low level waste is released into the sea or deposited at landfill sites.


Waste Management Concept for High Level Waste:

The reprocessing of spent fuel elements is no longer permissible in Finland. High level waste and spent fuel elements will be stored in deep geological formations. It will be possible to retrieve this waste.

Final Repository Situation for High Level Waste:

In 2001, Olkiluoto has been irrevocably determined as the site for the final repository for high level waste. Spent fuel elements are to be stored in a depth of 500 m in hard rock. The facility is expected to be licensed in 2012 and commissioned in 2020.


Problems:

Hard rock is jointed and it therefore carries water. According to latest scientific findings, even copper that has so far been said to be very corrosion-resistant would begin to rust under certain geochemical conditions in the final repository within 1,000 years. However, within this time frame, not even the less persistent atoms will have decayed
