NEA projections for planned long-term operation of the existing nuclear fleet and planned nuclear new build. Existing nuclear fleet operations are extended to 60 years unless specific policies are in place to shut down reactors early or to continue operations beyond 60 years. While other sections of this report are modelled out to 2030, the nuclear section of this report is modelled out to 2050. Because of the longer the timelines for nuclear energy projects, the effects of near-term decisions do not become evident until the 2030-2050 period.
