GoldSim is a very widely used probabilistic, generic modelling tool, designed to support investigation of complex systems in areas such as environmental impact assessment, water resources, engineering and finance. It is developed, maintained and sold by GoldSim Technology Group. Quintessa are GoldSim Certified Solution and Training Providers.

GoldSim's flexibility is achieved through a modular structure implemented through a highly graphical interface, with a heavy emphasis on exploring uncertainty through Monte Carlo and scenario-based analysis.

Quintessa use GoldSim as part of our range of modelling tools to support safety assessment work in radioactive waste management, most notably in support of the Low Level Waste Repository (LLWR) near Drigg in West Cumbria, UK, Sellafield Limited and Radioactive Waste Management Limited. For LLWR, GoldSim has been used for a wide range of activities, including to examining potential gas migration through the LLWR cap and the environmental impacts of coastal erosion at the LLWR site. For Sellafield, GoldSim has been used to undertake updated operational and post-closure radiological safety assessments for the Calder Landfill Extension Segregated Area (CLESA). The use of GoldSim in addition to other tools is part of our commitment to use the ‘right tool for the right job’ and reflect specific client needs.
