In October 1983 a study titled ''Effectiveness and Safety Aspects of Selected Decontamination Processes'' was initiated by the Nuclear Regulatory Commission. The thrust of the program was to review the current chemical decontamination processes being used to remove oxide films in light water reactor (LWR) primary coolant systems. Four different process applications, CAN-DECON, LOMI, DOW NS-1 and Dilute CITROX were observed at nine different facilities, two pressurized water and seven boiling water reactors. In addition, information on chemical decontaminations at four additional facilities was obtained. This report presents the results of this study as they pertain to the effectiveness of the chemical decontamination processes observed. The general topic areas of this report are (a) decontamination factors, (b) man-rem savings, (c) decontamination radwaste, and (d) problems observed and lessons learned.
