NUMERICAL MODELING OF MOISTURE TRANSFER IN THE STRUCTURES OF A NEAR-SURFACE RADIOACTIVE WASTE DISPOSAL FACILITY

The paper considers a model used to calculate the filtration flow in the structural elements of a near-surface radioactive waste disposal facility (RWDF). It presents the results of calculations focused on the filtration and humidity field rates inside the RWDF taking into account changes in the properties of the upper screen, concrete and packages with radioactive waste occurring over time. The study also analyzes the influence of the filtration flow field features on the safety barriers state.

Keywords: radioactive waste, RWDF structures, safety barriers, radioactive waste packages, degradation, filtration flow, humidity, rainfall drainage.
