Get to the Point
Countries should significantly expand nuclear power to meet climate and energy-security goals.
Summary
Supporters say nuclear power’s low lifecycle emissions, firm generation, and fuel security make it a crucial complement to renewables for deep decarbonization. Critics counter that high upfront costs, long construction timelines, accident legacies, waste management, and safeguards concerns make other clean-energy options faster or less risky. The policy question is whether cost, timeline, and governance challenges can be solved quickly enough for nuclear to play a major role in climate and energy-security goals.
Historical Context
Commercial nuclear power expanded rapidly beginning in the 1960s, slowed after major accidents and cost overruns, and has re-entered climate debates as countries seek firm low-carbon power. Recent interest includes life extensions, new reactor construction, and advanced reactors or small modular reactors, alongside parallel growth in renewables, storage, and efficiency. International bodies such as the IPCC, IEA, and IAEA frame nuclear power’s potential alongside persistent challenges in cost, timelines, radioactive waste, and safeguards.
