FIELD: nuclear power engineering. SUBSTANCE: method involves water filtering on solid sorbent that has difficult-to-dissolve isotopes corresponding to radioactive isotopes being extracted; steady isotope content in sorbent should be at least 0.1 mass percent. Chosen as hard-to-dissolve steady isotope compound are combinations of minimal solubility and maximal specific isotope content. EFFECT: improved cleaning selectivity. 14 cl, 6 tbl

Изобретение относится к очистке воды, например, охлаждающей контуры АЭС, от радиоактивных изотопов. Результатом, на которое направлено изобретение, является повышение селективности очистки. Для этого предложен способ очистки воды от радиоактивных изотопов путем фильтрации на твердом сорбенте, содержащем труднорастворимые соединения стабильных изотопов, соответствующих извлекаемым радиоактивным изотопам, при этом содержание стабильного изотопа в сорбенте должно быть не менее 0,1 мас.%. В качестве труднорастворимого соединения стабильного изотопа выбирают соединения с минимальной растворимостью и максимальным удельным содержанием изотопа 13.The invention relates to the purification of water, for example, the cooling circuit of a nuclear power plant, from radioactive isotopes. The result to which the invention is directed is to increase the selectivity of purification. To this end, a method is proposed for purifying water from radioactive isotopes by filtration on a solid sorbent containing sparingly soluble compounds of stable isotopes corresponding to extracted radioactive isotopes, while the content of the stable isotope in the sorbent should be at least 0.1 wt.%. As a sparingly soluble compound of a stable isotope, compounds with a minimum solubility and a maximum specific content of the isotope 13 are selected.
