DD is well advanced in the clean-up and release of the facility where Risø produced fuel for the experimental reactors. Come on a tour of the building and read about the task of removing radioactive contamination from floors, walls and drains.
They have raised the kursk nuclear submarine from the bottom of the arctic ocean and erected an overturned 80-ton crane at the Lindø shipyard after the 1999 hurricane. Now Dutch Mammoet with its muscle cranes must pull up a giant metal plug from Risø's largest research reactor.
In 2013, DD an important step forward towards removing and packing the inner parts of Denmark's largest research reactor DR3. We plan to lift the 22-ton steel plug at the reactor tank in spring 2014.
Follow the work to break down Denmark's largest research reactor DR3 from the former Risø Research Centre. Our task is to decontaminate the former experimental area on the Risø peninsula into a "green field" - i.e. to remove radioactivity and chemicals so that the area can be used without restrictions in the future. The DR3 reactor is one of the projects.
Danish Decommissioning had teamed up with Jan Sjöholm from 'Extrem Borr & Sågteknik AB' in Sweden, when the bearing holes from the top shelf in DR3 had to be removed.
By the end of 2012, Danish Decommissioning could tick off two major milestones.
After the last part of the 27 meter long conveyor channel was removed from the Hot Cell facility, the focus is on the next major stage; sandblasting of cell walls and floors via remote controlled equipment.
On 15 May, DD celebrate that an internal milestone was crossed when the last rig was selected by DR 3. It was a historic day for the technical crew, who were riding the lead-lined horizontal transport bottle for the last time.
DD has been busy this year with three major projects and a number of smaller tasks. There has been both momentum in the projects and teasing with procurement, and sometimes thinking outside the box to solve the tasks.
DDIn June, the expert panel will comment on the project description for the decommissioning of the DR 3 reactor, after which approval will be sought from the authorities and a dossier prepared for the Finance Committee of Parliament.
