separator assemblies, along with two compressors (one mounted on each end), and two water-cooled heat exchangers. Advantages of this process are a lack of criticality concerns due to the highly diluted feedstock and suitability for batch processing. This means Helikon-type plants can be relatively small, making the technology a nuclear proliferation concern.
