Manually-operated wet-blasting cell for decontamination



Manually-operated decontamination cell system for removing surface contamination on lower-level radioactive wastes of dismantled parts due to abolition of nuclear reactors, or reducing their contamination levels.


  • The closed system - reuse of water after removals - Iron powder retriever as well as sludge recovery unit collect abrasive particles and remove residues.
  • The closed system does not discharge waste water all the time because of the water circulation within the cell.
  • Less secondary waste due to durable special stainless abrasives can be used.
