Dismantling of nuclear plants often gives rise to a large quantity of radioactive contaminated (the surfaces contaminated with radioactivity) residue. By removing (decontaminating) of surface layers, the contaminated materials can be separated into reusable materials and radioactive waste.

For this purpose a process - known as the PHADEC method (PHosphoric Acid DEContamination) - has been developed that decontaminates contaminated steel by using phosphoric acid. In doing so, the components are immersed in a phosphoric acid bath and the contamination is dissolved. Remaining waste is less than 2%

For the Caorso nuclear power plant in Italy, which has been shut down, BNG supplies a PHADEC plant for a throughput of 1000 t/a.

After obtaining release for manufacture, assembly began in spring 2008. The plant was delivered to the customer in May 2009.
