Project: Modelling for DGR Safety Assessment, Ontario

Client: Nuclear Waste Management Organization

OPG is planning the construction of an underground facility for the management of low and intermediate level radioactive waste approximately 700 metres below the ground surface at their Western Waste Management Facility at the Bruce Nuclear site, in Kincardine, Ontario. Critical to the licensing process is modelling to demonstrate the safety of the facility in terms of the dose of radionuclides that would be experienced by various receptors at the ground surface over a million year period. The modelling involves simulation of a variety of processes which will occur following sealing and closure of the facility, including the generation of gas, the saturation of the mined-out caverns, the flow of groundwater within the tunnels and shafts, and the transport of radionuclides. Intera scientists and engineers have performed and continue to perform the necessary computations using sophisticated two and three-dimensional finite element and finite difference models of groundwater flow, gas flow, and contaminant transport, supported by our in-house code development and pre- and post-processors.
