SPECIATION OF RADIONUCLIDES IN BARRIER MATERIALS OF RADIOACTIVE WASTE STORAGES

JOURNAL: 2019, 9, p. 63-70

AUTHORS: G.A. Varlakova, A.S. Barinov

ANNOTATION:

The paper overviews the results of experiments performed to determine the speciation of cesium, cobalt and strontium in natural materials. Such materials are glaciolacustrine clay soils and sands considered as natural barriers in radioactive storage facilities. It was determined that changes in radionuclide speciation occur as the result of their continuous interaction with the barrier materials. Over time, fixed forms of cesium, cobalt and strontium radionuclides become predominant in the studied barrier materials.


Keywords: radioactive waste, radionuclides, speciation, barrier materials, interaction time, absorption.
