System Decontamination at Stade Nuclear Power Station in the Run-up to Dismantling Procedural Implementation

摘要

The Stade nuclear power plant, which is located right next to the river Elbe was decommissioned on 14 November 2003. Planning for the post-closure phase and later dismantling of the overall facility began already during regular operation. Chemical cleaning of radioactively contaminated surfaces, i. e. system decontamination, was prepared and carried out as a preliminary measure. The procedural implementation of the system decontamination described here incorporates stipulations for the expedient scope of the facility that is to be included in the system decontamination. As a result of the successfully completed system decontamination, it was possible to reduce substantially the dose-rate in the rooms of the facility.
