Western governments are reversing nuclear phase-outs just as renewables costs fall sharply — a collision of timelines that puts the role of nuclear in low-carbon energy transitions back at the center of policy debate.

A wave of Western governments are reversing decades-old nuclear phase-outs, with new small modular reactor projects attracting serious investment and political backing. Proponents argue nuclear is the only proven low-carbon baseload power source capable of replacing fossil fuels at scale, while critics point to cost overruns, waste storage, and the falling price of renewables. The debate sits at the intersection of climate policy, energy security, and long-term infrastructure planning.
