05 Mar Complex Cutting Operation in DR3

Danish Decommissioning partnered with Jan Sjöholm from ‘Extrem Borr & Sågteknik AB’ in Sweden when the storage facility holes from the top plate of DR3 needed to be removed.

DThis required specialized tools, as the storage facility holes had to be cut free from the top plate of DR3. Therefore, Danish Decommissioning partnered with Jan Sjöholm from ‘Extrem Borr & Sägteknik AB’. Jan specializes in performing complex drilling and cutting tasks.

The operation itself took one day, and Jan used an extended angle grinder to cut the holes free. Additional spot extraction and active ventilation were established during the work. There was a small amount of contamination in some of the holes, but no activation, as neutron sources have never been present in the storage holes.

The free-cutting is part of the preparation for the further work of dismantling the storage block so that it aligns with the master plan. The next step is to remove the spherical concrete to allow for the removal of the top plate. Subsequently, the remaining concrete can be dismantled.
