When the International Energy Agency’s chief warned in March 2026 that Europe had “maybe six weeks of jet fuel left,” the statement landed like a flare over global energy markets already buckling under the Iran war. But the ripple effects of that conflict stretch far beyond European airports. Across Asia and Africa, governments are turning to nuclear power with a speed and seriousness that would have seemed unlikely just a year ago.
South Korea is restarting idled reactors on an emergency timeline. Kenya and Rwanda are compressing nuclear development schedules that were supposed to unfold over decades. South Africa is revisiting expansion plans for its sole nuclear plant. And a new World Bank partnership with the International Atomic Energy Agency is rewriting the rules on how developing nations can finance their way into the nuclear club.
The common thread: the Iran war has exposed a vulnerability that cheap oil once papered over, and nuclear energy is emerging as the hedge of choice for countries that can no longer afford to depend on Middle Eastern hydrocarbons.
South Korea shifts from gradual embrace to emergency pivot
South Korea’s Ministry of Trade, Industry and Energy announced in March 2026 that it would accelerate the restart of offline reactors to offset oil and gas shortages caused by the Middle East crisis. Officials explicitly tied the revised schedule to wartime supply risks, transforming what had been a measured return to nuclear power into an operational scramble.
South Korea is well positioned to move fast. The country operates one of the world’s most mature nuclear fleets, with 26 reactors that supplied roughly 30 percent of its electricity before several units were taken offline for maintenance and policy reasons under previous administrations. Trained operators, an established regulator (the Nuclear Safety and Security Commission), and existing grid connections mean that restarting idled units is a matter of adjusting maintenance cycles and regulatory approvals, not building from scratch. Industry analysts expect additional capacity to come online within months, not years.
The urgency is real. South Korea imports virtually all of its oil and roughly a third of its liquefied natural gas from the Middle East. With shipping routes through the Strait of Hormuz disrupted and spot prices for LNG cargoes surging across Asia in early 2026, the economic case for maximizing domestic nuclear output has become difficult to argue against, even for lawmakers who had previously favored phasing reactors out.
Africa’s nuclear ambitions collide with ground-level reality
The picture in Africa is more complex and far less immediate. Kenya, Rwanda, and South Africa are each accelerating nuclear energy planning as the energy shock lays bare their dependence on imported fossil fuels, according to Associated Press reporting from April 2026. But the three countries occupy very different positions on the nuclear learning curve.
South Africa is the only nation on the continent that currently operates a commercial nuclear power plant. The Koeberg station outside Cape Town, with two pressurized water reactors, has generated electricity since the 1980s. Eskom, the state utility, has discussed building additional units for years, but financing constraints and political uncertainty have repeatedly stalled those plans. The Iran war appears to have injected new momentum: South African energy officials have signaled a willingness to revisit expansion timelines, though no construction contracts or firm budget commitments have been announced as of May 2026.
Kenya and Rwanda face a fundamentally different challenge. Neither country operates a reactor or possesses the regulatory infrastructure, trained workforce, or waste management systems required to do so. Kenya’s Nuclear Power and Energy Agency has been conducting feasibility studies and site assessments for several years, but the gap between those preliminary steps and breaking ground on a reactor is enormous. Rwanda has expressed interest in small modular reactors, a newer technology that promises lower upfront costs and shorter construction timelines, but no SMR design has yet been deployed commercially in Africa.
For both countries, the realistic timeline from policy commitment to first electricity is at least a decade, and likely longer. Building a nuclear program from scratch requires establishing an independent regulatory body, training hundreds of specialized personnel, developing emergency preparedness plans, and upgrading grid infrastructure to handle large baseload generators. These are not steps that can be compressed by political urgency alone.
The vendor question no one is ignoring
Any discussion of nuclear expansion in Africa inevitably involves Russia’s Rosatom, the state nuclear corporation that has signed cooperation agreements with more than a dozen African governments over the past decade. Rosatom has positioned itself as the most accessible vendor for newcomer states, offering financing packages, training programs, and turnkey construction deals that Western competitors have struggled to match.
That dynamic creates a geopolitical layer beneath the energy story. Western governments and multilateral institutions have grown increasingly uncomfortable with Rosatom’s expanding footprint, particularly as the war in Ukraine continues to strain Russia’s relationships with the broader international community. The new World Bank-IAEA partnership can be read, in part, as an attempt to offer African nations a credible alternative pathway into nuclear energy, one that does not route through Moscow.
World Bank breaks a long-standing taboo
In June 2025, World Bank Group President Ajay Banga and IAEA Director General Rafael Grossi signed a memorandum of understanding formalizing cooperation on nuclear energy in developing countries. Banga framed the partnership around nuclear’s role in economic development, and the IAEA committed to providing support across the full lifecycle: planning, construction oversight, fuel supply coordination, waste management, and long-term safety supervision.
The significance of this agreement is easy to understate. The World Bank had effectively avoided nuclear power financing for decades, citing concerns about cost overruns, safety risks, and radioactive waste. A 2023 internal energy policy review cracked the door open by acknowledging nuclear as a potential tool for decarbonization, but the formal partnership with the IAEA represents a much more concrete step.
What remains unclear is whether the partnership will translate into direct project financing. The memorandum establishes a framework for technical assistance and policy advice, but the World Bank has not disclosed specific funding commitments for nuclear construction in any country. For African nations that lack the capital to build reactors on their own, the distinction between technical guidance and actual loans is the difference between a plan on paper and a plant on the ground.
The gap between rhetoric and reactors
The Iran war has undeniably strengthened the political case for nuclear energy across multiple continents. IEA chief Fatih Birol’s blunt warning about fuel reserves, South Korea’s emergency reactor restarts, and the World Bank’s institutional pivot all point in the same direction: nuclear power is being reconsidered with a seriousness that the pre-war energy landscape did not demand.
But political will and operational reality remain separated by years of work, billions of dollars, and unresolved questions about public acceptance. No polling data from Kenya, Rwanda, or South Africa has surfaced showing how citizens in potential host communities view nuclear expansion in the context of wartime energy insecurity. Nuclear projects worldwide have stalled when local opposition emerged around safety fears, land use disputes, or distrust of central authorities. Governments announcing accelerated timelines have not yet had to contend with that friction.
The most honest reading of the evidence as of May 2026 is this: the Iran conflict has compressed political timelines and elevated nuclear energy from a long-term aspiration to an urgent priority in several countries. South Korea, with its existing fleet and institutional capacity, can act on that urgency quickly. African newcomer states cannot, no matter how strong the political signal. The question that will define the next decade of global energy policy is whether the sense of crisis outlasts the crisis itself, sustaining the financing, regulatory development, and public engagement needed to turn today’s announcements into tomorrow’s operating reactors.
