Radiating change

Teollisuuden Voima Oyj will dispose of low and intermediate-level radioactive waste generated at the Olkiluoto NPP in a final disposal facility. It was commissioned in 1992 and in 2012 the government gave permission for the disposal of radioactive waste generated in industry, medical care and research and for which the State is responsible, at the Olkiluoto VLJ repository. The Olkiluoto VLJ repository consists of an access tunnel, a shaft and two rock silos at a depth of 60–95m, where the waste is disposed of. Low-level waste is packed in concrete boxes, placed in their own silo. The intermediate-level waste silo mainly contains liquid waste mixed with bitumen. The bitumen barrels are packed in concrete boxes. At the end of the disposal, the facility spaces are filled with concrete. Source: TVO / STUK
