Areva was chosen to decontaminate a pressurized water reactor at the Grafenrheinfeld nuclear plant as part of the end of the reactor’s operation. The work will reduce the radiation levels in the reactor pressure vessel, auxiliary systems and piping. The project is expected to be completed in late 2016.
The decontamination will proceed using the CORD UV and the AMDA techniques. It is based on the progressive injection of chemical products into the reactor’s primary circuit. Once the process is completed, the chemical substances used are decomposed into carbon dioxide and water. The process can be used in operating nuclear plants to reduce the dose level during maintenance activities, and it can also be used as a preparatory measure before decommissioning.
