Sensitivity analysis of parameters influencing solute transport from a deep repository of spent nuclear fuel

Popis výsledku v původním jazyce

This contribution deals with computation of concentration of radioactive species released from a deep repository of spent nuclear fuel. Flow123D, a 3D modelling software based on the finite volume method, was used. Multiple scenarios were computed for selected critical isotopes. The scenarios differ in the lifespan of spent nuclear fuel containers. Based on the computed concentrations, the sensitivity analysis was performed for the C14, Cl36 and I129 isotopes (with I129 being the most critical one). Certain input parameters (hydraulic conductivity, fracture ap-erture and sorption parameters) were being changed to determine their influence on the change in concentra-tion. Next, the Monte Carlo method was applied with the same input parameters being changed. 100 realisations were carried out. The result was the determination of probability that for the selected scenario of "drinking 1 m3 of groundwater per year" the maximum allowed dose of 0.25 mSv will not be exceeded.
