Deep borehole disposal of nuclear waste: engineering challenges
In recent years, geological disposal of radioactive waste has focused on placement of highand intermediate-level wastes in mined underground caverns at depths of 500–800 m. Notwithstanding the billions of dollars spent to date on this approach, the difficulty of finding suitable sites and demonstrating to the public and regulators that a robust safety case can be developed has frustrated attemp...
متن کاملSensitivity Analysis of Seals Permeability and Performance Assessment of Deep Borehole Disposal of Radioactive Waste
The concept of disposal of high-level radioactive waste in deep boreholes, and probabilistic performance assessment (PA) of a generic disposal system are described. A series of preliminary PA simulations, conducted to evaluate the possible migration of radionuclides to an accessible environment, are presented. The PA simulations provide estimates of radionuclide releases and mean annual radiati...
متن کاملNumerical modeling of radionuclide migration through a borehole disposal site
The migration of radionuclides from a borehole repository located about 20 km from the Akwapim fault line which lies in an area of high seismicity was analyzed for some selected radionuclides. In the event of a seismic activity, fractures and faults could be rejuvenated or initiated resulting in container failure leading to the release of radionuclides. A numerical model was solved using a two-...
متن کاملSafety Indicators for the Safety Assessment of Radioactive Waste Disposal
FOREWORD Plans for disposing of radioactive waste have raised a number of unique and mostly philosophical problems, mainly due to the very long timescales which have to be considered. While there is general agreement on disposal concepts and on the approach to establishing that disposal facilities are safe, consensus on a number of issues remains to be achieved. To assist in promoting discussio...
متن کاملMODFLOW/MT3DMS Based Modeling Leachate Pollution Transfer in Solid Waste Disposal of Bahar Plain Deep Aquifer
Abstract Background and purpose: This paper presents a case study in simulation of process governing leachate occurrence and subsequent transport, and investigates its migration away from the landfill to control environmental adverse effects on a deep aquifer. Materials and Methods: The landfill examined in this study was an area of 240 ha and received 500 ton/day of solid waste generated fro...
