The results of research and regular monitoring of the outflow of radioactive aerosols, as well as leakages of contaminated water from Shelter rooms, were summarized. Formation of radioactive aerosols and liquid radioactive waste (LRW) inside the Shelter were shown to be interconnected, which should be taken into account when addressing the problem of improving the safety of the Shelter. An efficient and economical process flowsheet was proposed for management of the Shelter LRW involving separation of the LRW flows with high and low content of transuranium elements and organic compounds, treatment of a relatively small LRW flow to remove transuranium elements and organic compounds, and processing of the pretreated waste on standard installations of the Chernobyl NPP.
