Corrosion and fouling test setup (KorrVA/ PETrA)

  • Experimental investigation of corrosion processes as well as transport and deposition of corrosion products at core structures during loss-of-coolant accidents (LOCA) in pressurized water reactors (PWR)
  • Characterization and quantification of organic and crystallization fouling at process apparatuses (e.g. heat exchangers)
