【 摘 要 】

Molten salt extraction and electrorefining of plutonium were successfully conducted with only a 200g initial charge. Due to this small scale, the electrorefining cell components were redesigned relative to conventional, multi-kg standards. The efficiency and yield of this small-scale process are comparable to those of larger-scale exemplars. Chemical analysis of the plutonium product and the anode heel is presented. The product was 99.8% pure. The anode heel was able to be depleted beyond the expected freezing point without significant impurity carryover. (c) 2021 Elsevier B.V. All rights reserved.
