The culminating argument of each program is a 'Safety Case' for a specific disposal concept containing, among other elements, the results of performance assessment simulations whose object is to model the release of radionuclides to the biosphere.
Future human intrusion into a geological repository for spent nuclear fuels and radioactive waste is a safety case that inherently involves a high uncertainty, especially in areas with a high population density.
This "just in case" measure can be a safety net in case any unforeseen accident happens e.g. a fire, an injury or a lawsuit.
The incident meant Mercedes were forced to bring forward Hamilton's stop in case there was a safety car, which in turn meant his tyres ran out of grip before the end of the race when he was trying to pass Bottas.
The intention, in this paper, is to show that if an accident involved the failure of multiple barriers, it is also possible to trace the common causes of those failures back to the assumptions and arguments that are embodied within a safety case.
As part of the student learning, groups of three to four students were each given a safety case study to investigate and report on to the rest of the class.
These insights could be used in making a safety case or developing a new licensing review infrastructure for advanced reactors including Generation IV reactors.
Next up is Shelter, which is a portable safety case where you can store essential goods, like the last ever Snickers bar on a post-apocalyptic earth.
The one activity that dominates the design, construction, commissioning, operation, and ultimately decommissioning of all nuclear facilities is their safety case: yet for all its importance, the development of a safety case is quite a nebulous activity that can be difficult to comprehend.
Identifying and evaluating the factors that might impact on the long-term integrity of a deep Geological Disposal Facility (GDF) and its surrounding geological and surface environment is central to developing a safety case for underground disposal of radioactive waste.
