Dismantling and decommissioning of an Uranium processing plant at Andujar (Spain)

The dismantling and decommissioning of the Uranium Processing Plant at Andujar is the first experience of such a kind in Spain. The factory houses almost 1 million cubic meters of uranium esterile ores concentrated in two different landfills covering 94,000 square meters, as a results of mining activities between 1959 and 1981. The project will stabilize both landfill containers ''in situ'' by using the products obtained after dismantling factory buildings and installation of processing. Decommissioning will take place at the end of 1993. Before dismantling works started, a number of geological, geotechnical, sysmologic, environmental, migration parameters of radionuclides from the landfill and socio-economical studies were conducted. The different phases of wastes conditioning and the updated situation of work plan are described
