Abstract

There is a significant lack of research regarding the coastal flood resilience of nuclear decommissioning sites, an issue that necessitates continuous assessment. As climate change associated sea level rise (SLR) projections are fuelling concerns about the long-term safe management of radiological inventory, and efficient progression of decommissioning, emphasised by the growing number of facilities entering decommissioning phases globally. A significant collection of literature was reviewed to collectively inform the reframing of resilience, which also aims to guide the development of coastal flood resilience index assessments through identification of indicators. Within this paper, resilience was reframed as the ability of the decommissioning site to maintain continuous essential operations, respond effectively, incorporate adaptations, and retain essential objectives. This approach presented decommissioning sites as systems, highlighting elements within dimensions that strongly influence resilience capabilities, further informed by the widely recognised framework (seismic resilience) that identifies key qualities required for sufficient resilience within a system. Focus on requirements of maintaining continuous essential operations was underpinned by the need to represent operational degradation and responses required to understand when resilience is being lost, and when it is no longer resilient, represented through thresholds. Overall, the synthesis of these elements into a reconceptualised resilience ability applicable for decommissioning contexts is significantly beneficial. As it provides a foundation not only for future research towards resilience in decommissioning sites, but for practical application, particularly in aiding index-based assessments with indicator identification within nuclear decommissioning sites for coastal flood and general natural hazard resilience.
