STORAGE FOR SOIL AND VEGETABLE REMNANTS CONTAMINATED WITH RADIOACTIVE STRONTIUM AND CESIUM ISOTOPES Russian patent published in 2000 - IPC

FIELD: storage of radioactive wastes. SUBSTANCE: storage for soil or vegetable remnants contaminated with Strontium-90 and Cesium-137 isotopes is constructed as part of set of industrial barriers in mellow ground wherein they are self-cleaned to prevent propagation of radioactive isotopes in surface and underground water and in ground. Storage is made in the form of pit with layers of clay on its walls and bottom. Novelty is that clay used for the purpose is layer of montmorillonite clay carrying ash layer with limonite powder and gypsum chippings with lime chippings. Proportion of components of double- component insulating layers is 1:1. EFFECT: simplified design and improved reliability of storage. 2 cl, 1 dwg
