Localized fuel temperature instabilities resulted in heavy vessel contamination by Cs-137 and Sr-90. The reactor vessel was filled with light concrete in order to fix the radioactive dust and in 2012 the reactor vessel of was to be moved to intermediate storage until a permanent solution is devised. The reactor buildings were to be dismantled and soil and groundwater decontaminated. AVR dismantling costs were expected to far exceed its construction costs. In August 2010, the German government estimated costs for AVR dismantling without consideration of the vessel dismantling at 600 million € ( $750 million, which corresponded to 0.4 € ($0.55) per kWh of electricity generated by the AVR. A separate containment was erected for dismantling purposes, as seen in the AVR-picture.
