An evaluation of dilute chemical decontamination technology for Boiling Water Reactor (BWRs) was completed under the Dilute Chemical Decontamination Program. An integrated process was developed and demonstrated under simulated BWR decontamination chemical conditions using a 76 cm long section of 15 cm piping removed from an operating BWR. Reasonable process conditions are: 0.012 M oxalic acid and 0.005 M citric acid at pH 3.0 and 90/sup 0/C with a controlled dissolved oxygen concentration of 0.75 ppM. A novel reagent regeneration process using anion-exchange resin preloaded with oxalate and citrate anions was developed to remove the dissolved corrosion products, including Fe(III), from solution during the decontamination. A limited corrosion testing program was completed and no severe adverse effects were identified.
