Sillamäe |
Sillamäe was the site for a chemical factory that produced fuel rods and nuclear materials for the Soviet nuclear power plants and weapon facilities, while Paldiski was home to a Soviet Navy nuclear submarine training centre.
During 1946–1952, a marine variety of Dictyonema shale was used for uranium production in Sillamäe, Estonia, and during 1950–1989 alum shale was used in Sweden for the same purpose.
