GAS RELEASE FROM DEEPLY BURIED LIQUID RADIOACTIVE WASTES

摘要

The results of a generalization and analysis of data accumulated over a period of 40 years on the actual gas release from injected wells in test areas for underground disposal of liquid wastes with various levels of activity from the Siberian Integrated Chemical Plant and the Zheleznogorskii Integrated Mining and Chemical Plant are presented. It is concluded that in order to extend the operation of the test areas beyond the prescribed time limits the presence of a gas phase in the reservoir formations, formed over the period during which they were actively used, must be taken into account carefully. The investigations should be extended to the problem of gas release and priority must be given to determining the contribution of the different components of this process and investigating their mechanisms and to developing a mathematical model of gas release and a computer program to predict the development in order to ensure safe operation of the areas used to test underground disposal.
