GSL are world leaders in radiological and non-radiological impact assessment and modelling. This includes scenario development, FEP (feature, event and process) management, uncertainty management, environmental simulation, and probabilisitc and deterministic modelling of different exposure pathways and mechanisms. The general approaches we take to developing safety cases and safety assessments parallel the procedures developed and refined in national and international programmes over many years. However, the actual approach followed in each project is discussed and agreed according to the specific objectives and context.
A particular aspect of risk assessment and management in which GSL specialises, is the development of safety cases and permit or licence applications. For example, GSL was involved in the successful application for the licensing of the world’s only deep geologic repository for long-lived transuranic waste, and GSL has led the development of Environmental Safety Cases for authorisation of waste disposal facilities in the UK.
