AbstractAbstract
[en] Electrochemical decontamination has been demonstrated to be very effective in removing plutonium nitrate contamination (0.5 μg cm-2) on stainless steels. The amount of metal dissolved to achieve a DF of 102 to 103 was 2 to 7 μm depending on the electrolyte used. In unstirred electrolytes 1M HNO3, 1M HNO3/0.1M NaF, 5M HNO3 perform best. Under stirred electrolyte conditions, there is a general marginal fall in effectiveness except for 5M HNO3 where there is a slight improvement. The optimum performance is a compromise between maximizing the electrolyte throwing power and minimizing substrate surface roughening during decontamination. (author)
