Use of chemical reagent processes to remove oxide films in primary coolant system piping has been widely performed in US light water reactors in 1984 and 1985. The principle application of chemical decontamination was in boiling water reactor (BWR) primary coolant and cleanup systems and in pressurized water reactor (PWR) steam generators, both primary and secondary sides. These chemical decontaminations were performed prior to inservice inspections or system repair to reduce the man-rem that would be received by the work force to perform the specified task(s). This paper presents information and results on (1) methods used for determining decontamination factors (DFs), (2) actual DFs obtained with chemical decontamination methods, (3) waste forms and volumes generated, (4) resultant man-rem savings and (5) lessons learned.
