Summary

The two-phase flow model realistically simulates nuclear waste leaching, showing slower, wider contaminant spread compared to single-phase models. This stochastic approach offers probabilistic insights for better environmental and public health risk assessments.

Area of Science:

  • Environmental Science
  • Hydrogeology
  • Nuclear Engineering

Background:

  • Accurate modeling of contaminant transport from nuclear waste sites is crucial for environmental and public health protection.
  • Traditional single-phase flow models may not fully capture complex subsurface processes like gas-water interactions.
  • A physically motivated model is essential for analyzing leaching impacts.

Purpose of the Study:

  • To investigate the effect of the two-phase flow model on water content and solute transport.
  • To develop and apply a stochastic approach for probabilistic contamination assessment at a nuclear waste site.
  • To compare the outcomes of two-phase flow modeling with single-phase flow modeling.

Main Methods:

  • Theoretical investigation of two-phase flow effects on water content.

  • Monte Carlo simulation of solute transport using saturated hydraulic conductivity as a random variable.

    • Main Results:

    • The two-phase flow model yields slightly less water content (1.5%) than the single-phase model.
    • Two-phase flow results in slower but wider lateral spreading of contaminant plumes in the unsaturated zone.
    • The stochastic approach provides probabilistic contamination assessments, unlike deterministic methods.

    Conclusions:

    • The two-phase flow model offers a more realistic representation of solute transport from nuclear waste sites.
    • Stochastic modeling enhances understanding of contaminant plume behavior and uncertainty.
    • Probabilistic assessments support informed waste management, environmental evaluation, and public health impact assessment.
