Simulation of an underground nuclear waste disposal site

nuclear-energy-insider 200A number of different approaches in nuclear waste disposal are being researched, with the primary goal being the prevention of leakage.

Burial designs can be assessed by analyzing the likely outcomes of potential failure modes using finite element analysis. The fully coupled temperature-displacement-pore pressure capability in Dassault Systèmes’ Abaqus can be used to perform such simulations.

Check out this paper that maps out the results from the testing and will enable you to:

  • Understand how physical processes including, heat generation from residual radioactivity, heat transfer, and material swelling—can induce stress in the waste containment structure can impact on devoloping safe long-term disposal schemes
  • Gain insight on the Abaqus Finite Element Analysis that was used to create a waste canister containing spent nuclear fuel located in a cylindrical cavity drilled deep in the bedrock
  • Understand which variables were monitored in order to create an accurate axisymmetric model of the scenario to gain cutting edge insight on results from the tests
