Radioactive waste stored in steel drums.

LONG-TERM SOLUTION FOR DANISH RADIOACTIVE WASTE

Preliminary studies of concepts for a final repository have been carried out from 2009-2014.

In March 2015, The Danish political parties decided to elaborate studies leading towards an intermediate long-term storage facility for Danish low- and intermediate radioactive waste (LILW).

The studies regarding operation, economy, localization criteria and comparative safety levels of an intermediate storage facility were completed in late 2016.

Danish Decommissioning was assisted by COWI consulting group in the studies of operation, economy and safety. Read their report published in August, 2016.

A study of localization criteria was conducted by The Geological Survey of Denmark and Greenland. Read a summary of the total long-term storage studies.

The Danish Parliament is to decide on a long-term solution in 2017.

In 2003, the Danish Parliament gave its consent for the Government to start preparing a 'basis for decision' for a final repository for Denmark's low- and intermediate level radioactive waste. Preliminary studies of concepts were carried out from 2009-2014. Further studies are paused until further notice.

DD's part of the preliminary investigations concerns the theoretical studies of three different concepts for the repository, each located in four different typical Danish geological settings. These studies ran from October 2009 until April 2011.

The radioactive waste is estimated to a total amount of up to 10,000 m3 and can be grouped as follows:

  • Decommissioning waste from the nuclear facilities at Risø
  • Existing waste of low activity originating from the operations at the nuclear facilities at Risø and from external users
  • Existing waste of intermediate activity originating from the nuclear facilities at Risø
  • Special waste (mainly spent fuel used for post irradiation experiments and larger α-sources)
  • Contaminated concrete and tailings (the latter classed as potential waste only)

A large part of the waste has been conditioned in 210-litre concrete-lined waste drums. Waste packed in large ISO or steel containers has not yet been conditioned. The conditioning of the 'special waste' in particular will depend on the choice of repository concept.
