NEA RWMC Workshop on Developing Safety Cases for Various Radioactive Waste Disposal Facilities Needs and Challenges of RWMC Organisations
A safety case is a collection of safety evidence and arguments that demonstrate the safety of a management process or facility throughout its lifetime. While the types of data, calculations, and analyses are different for demonstrating safety in various waste management processes, the approach and strategies used to structure safety cases for different back end processes have aspects in common. For example, the safety objectives for both geological and near surface disposal are to identify a suitable disposal site, in which to design, construct, operate and close a disposal facility so that protection before and after closure is optimised, with social and economic factors taken into account. Thus, the expertise, approach and strategies required for the development of assessment scenarios, the management of uncertainties and the associated risk evaluations in compiling and presenting safety cases for different disposal facilities share some commonalities.
