Temperature Fields with Deep Burial of Liquid Radioactive Wastes: Simulation of Multistage Disposal

Atomic Energy Aims and scope

Abstract

Newly developed computer codes were used to investigate the temporal and spatial variation of the temperature in a collector-stratum during multistage disposal of liquid wastes. It is shown that measurement of the temperature in the injection well after waste disposal has been completed can serve as an objective criterion for the thermal state of the stratum only if no technological operations are performed in the well. Comparing models with spherically and cylindrically symmetric arrangements of the wastes in the stratum shows that when calculating the temperature field at the active stage of the operation of the injection well both models give virtually identical results, while for calculations of the field after waste disposal has been completed the simplified spherically symmetrical model underestimates and the cylindrical model overestimates the maximum stratum temperature. 6 figures, 3 references.
