Since the Fukushima reactor meltdowns, there has been increased public concern in Japan regarding nuclear issues and also on the potential of major natural hazards to cause accidents at nuclear facilities. In response to this – and to help rebuild the public confidence required to site a repository – studies have examined how the concept of resilience, as commonly applied in the nuclear power industry, could be applied to geological repositories for direct disposal of spent fuel or vitrified high level waste (HLW). This paper takes that work further, considering how the concepts could be taken over for the more technically challenging TRU waste.
