Long- term solutions for high-level radioactive waste are under development (medium confidence)± Low impacts to biodiversity but high impact in case of an accident (medium confidence)Section 6.4.2.4, Figure 6.18Depends on the type of power plants being displaced Nuclear requires significantly less minerals than other low-carbon technologies Carbon capture and storage (CCS)+ CCS infrastructure generally requires reduction of air pol- lutants for optimal operation (high confidence)– Water use generally increases significantly; significant water treatment needs may also arise for brines (high confidence)+ Potential to spur technological innova- tion; also could reduce inequity risks for fossil workers (high confidence)+ Could help decarbonise some hard- to-decarbonise sectors (high confidence)± Use of resources and chemicals could increase unless appropriately managed (medium confidence)+ Low-carbon emissions
