abstract

In Eastern Germany uranium mining lasted from 1946 till 1990 including a production of in total 220,000 t of uranium. The Seelingstädt Uranium Mill and Processing Plant, located in Thuringia, Germany, was one of two large uranium mills owned by Wismut. The mill was erected by 1960 and covered an area of 93 ha. From 1961 till 1991 a total of about 110 million t of different types of uranium ores were milled and processed at the Seelingstädt mill. The mill produced ca. 110,000 t of uranium (in yellow cake). Demolition of the buildings and industrial facilities of the Seelingstädt mill and processing plant site are nearly completed. The site is being decommissioned with respect to after-use aiming at afforestation and grasslands allowing for a stable plant succession. Decommissioning includes excavation and relocation of contaminated materials, reshaping of the site and construction of ditches for granting a stable surface runoff as well construction of access and maintenance roads. About 85% of the demolition and relocation works have been completed till to date. Last decommissioning works shall be completed by 2015. The present paper presents experiences made and progress achieved till to date.
