Reprocessing of Liquid Radioactive Wastes, from Nuclear Power Generation, in Autonomous Mobile Purification Facilities

The necessity for and ways to improve the technology for reprocessing liquid radioactive wastes from nuclear power generation are substantiated taking account of the chemical contaminants (petroleum products and products of corrosion). As a general solution, it is proposed that autonomous modular purification facilities, operating on the principle of combining baromembrane and sorption methods, be developed. The basic scheme of the proposed technology and the construction of the purification facilities are described. The results of industrial tests performed on a tanker for collecting liquid wastes from the Pacific Ocean fleet are presented. It is shown that purification to the level of allowed discharges into the sea is possible and that the radioactive concentrates formed can be solidified by cementation.
