Technical University of Denmark
The Technical University of Denmark , often simply referred to as DTU, is a university just north of Copenhagen, Denmark. It was founded in 1829 at the initiative of Hans Christian Ørsted as Denmark's first polytechnic, and is today ranked among Europe's leading engineering institutions, and the...

, the Danish Transport Research Institute and Risø National Laboratory. Before this it was a research institute under the Danish Ministry of Science Technology and Innovation and consisted of eight research departments: Biosystems, Polymer Department, Fuel Cells and Solid State Chemistry, Materials Research, Optics and Plasma Research, Radiation Research, Systems Analysis and Wind Energy.

The mission of Risø is "to create new knowledge based on world-class research, and to ensure that our knowledge is used to promote the development of an innovative and sustainable society" (from the web page).

Risø was founded in 1956, but not officially inaugurated until 1958. Niels Bohr

 played a key role in the founding of Risø and was chairman of the Nuclear Energy Commission charged to promote the peaceful use of nuclear power.

The organization employs about 700 staff (660 man-years) as of 2005; the area of the grounds is over 2.6 square kilometres.

Risø is the site of three research nuclear reactors: DR-1, DR-2 and DR-3. DR-3 is a DIDO class nuclear reactor
Nuclear reactor
A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Most commonly they are used for generating electricity and for the propulsion of ships. Usually heat from nuclear fission is passed to a working fluid , which runs through turbines that power either ship's...

. All reactors are shut down and undergoing decommissioning.

Risø is today particularly noted for its involvement in wind energy

 and solid-oxide fuel cells.

Risø has strong competences in climate change effects studies and has "state of the art" facilities for realistic climate change experiments and monitoring. These include:
  • RERAF (Risø Environmental Risk Assessment facility) - a phytotrone controlled environment growth facility.
  • Sorø beech forest. A field station in an 80-year-old beech forest measuring carbon inputs, outputs and turnover processes by advanced techniques (e.g. eddy covariance
