Heavy water cell from Vemork

An original piece of equipment from the Vemork heavy water plant on display in the Norwegian Resistance Museum in Oslo. The plant was destroyed by resistance saboteurs in 1943, a major setback for Germany's Second World War atomic weapons programme. The success of Operation Gunnerside was later regarded by Britain's Special Operations Executive as the most successful act of sabotage in the war. Here's to the real Heroes of Telemark.
