French multinational company AREVA has been appointed by utility E.ON Kernkraft to decontaminate Grafenrheinfeld nuclear power plant in Germany.
This will help reduce the radiation level in the water reactor's pressure vessel, auxiliary systems, and piping.
The process will be carried out by using a combination of two AREVA techniques AMDA and CORD UV, which involve progressive injection of chemical products into the primary circuit of the reactor.
On completion, the chemical substances will be decomposed into carbon dioxide and water, with no waste product. The process can be effectively applied while the plant is in operation.
It can also be used as a preparatory measure before decommissioning, which can help reduce leftover radioactive waste.
AREVA Reactors and Services Business Group's sales executive vice president Michael Cerruti said: "AREVA's decontamination technology has already been used reliably in over 30 nuclear facilities worldwide, including boiling and pressurised water reactors.
"This new contract confirms customer confidence in our decontamination technology."
The Grafenrheinfeld nuclear power plant decontamination project is expected to be completed during Q4 of this year.
