In May 2014, Danish Decommissioning carried out a major operation: lifting the 22-ton heavy metal plug from Denmark's largest research reactor DR3. The actual lifting of the plug took one hour, and the operation can be viewed in timelapse here.
Attend the Open House at Danish Decommissioning and learn about our unique environmental mission at Risø: Friday, June 13, 3 PM-6 PM.
Success: The massive metal plug that sealed Denmark's largest research reactor DR3 has been successfully removed and replaced with a lid. Due to intense radiation from the reactor tank, this historic operation has been meticulously planned over recent years. DD commends the collaboration with Mammoet and Bladt Industries.
DD has achieved substantial progress in the decontamination and release of the facility where Risø manufactured fuel for the research reactors. We invite you to explore the building and learn about the intricate process of removing radioactive contamination from its floors, walls, and drainage systems.
They have raised the nuclear submarine Kursk from the bottom of the Arctic Ocean and uprighted a toppled 80-ton crane at the Lindø shipyard after the 1999 hurricane. Now, the Dutch company Mammoet, with its powerful cranes, is tasked with extracting a massive metal plug from Risø's largest research reactor.
The annual report contains an account of DD's activities in 2013 and reports on the results achieved in relation to the performance contract.
Danish Decommissioning is dismantling experimental reactors and other nuclear installations on Risø. Part of our task is to deal with radioactive waste, and a small part of the total is "special waste".
In 2013, DD achieved a significant milestone towards removing and packaging the internal components of Denmark's largest research reactor, DR3. We plan to lift the 22-ton steel plug on the reactor vessel in spring 2014.
Danish Decommissioning has been granted DKK 1.1 million to prepare a decision basis for the Danish Parliament regarding the establishment of a Danish interim storage facility for low and intermediate-level waste. This will be done in collaboration with GEUS and the Danish Institute for Radiation Protection (SIS).
Follow the progress of decommissioning Denmark's largest research reactor DR3 from the former Risø Research Centre. Our task is to decontaminate the former research area on the Risø peninsula to "green field" – meaning to remove radioactivity and chemicals so that the area can subsequently be used without restrictions. The DR3 reactor is one of these projects.
