The Nuclear Energy Outlook's ambitious vision for the future of nuclear power is a call to action for OECD countries to embrace a transformative scenario. This scenario, while challenging, is the only way to reach the COP28 goal of achieving net-zero emissions by 2050. It requires a fundamental shift in government policies, project execution, industrial capabilities, and financing schemes. The report outlines four scenarios, each with a different outlook for nuclear capacity by 2050, but it's the transformative scenario that truly captures the potential for a sustainable energy future.
The transformative scenario envisions a global nuclear capacity of 1,324 GWe by 2050, a more than threefold increase from today's levels. This ambitious goal is achievable through a combination of long-term extensions of existing reactors, accelerated large-scale reactor new builds, and substantial small modular reactor (SMR) deployments. However, the report highlights the significant challenges that lie ahead, particularly in OECD countries.
One of the key challenges is the current concentration of new nuclear activity in non-OECD countries, especially China and Russia. These countries are driving 80% of near-term nuclear construction, leaving OECD nations struggling to keep up. To address this, the report emphasizes the need for a radical transformation of government policies and industrial approaches in OECD countries. This includes aggressive new build rates that far exceed recent experience, which is a daunting task.
Maximizing the operation of existing reactors is another critical aspect. Many reactors in OECD countries will reach the end of their initial licenses before 2040, and securing extensions to 60 or 80 years is essential. This requires addressing the challenges of reactor licensing and ensuring that power plants can continue to operate safely and efficiently.
SMR deployment is also a central part of the transformative scenario. The report suggests that mass manufacturing, product-based licensing, prequalified sites, and aggregated demand are necessary to support robust order books. While the enabling conditions for mass manufacturing are unlikely to be fully in place before the 2040s, the report predicts that SMRs may play a more significant role in the second half of the century, provided that regulatory harmonization, factory production, and customer demand aggregation can be advanced simultaneously.
The report also highlights the supply chain and workforce capacity challenges that OECD countries face. Limited new builds over the past 25 years have weakened the industrial workforce, supply chain, and project delivery capabilities. To overcome these obstacles, close cooperation among like-minded countries, stronger industrial partnerships, and a shift from project-by-project to program-based deployment are recommended. This approach provides visibility for investment, supports standardization, enables learning effects, and reduces construction costs.
Financing is another critical aspect of the transformative scenario. OECD countries face significant capital expenditure challenges, with recent global spending averaging around $30 billion per year, driven mostly by China and Russia. The report stresses that global capital expenditure needs to rise sharply, with OECD countries requiring an average of $143 billion per year during the 2030s. Mobilizing private capital through bankable project structures, clear risk allocation, credible revenue models, and government-backed mechanisms is essential to overcome fiscal pressures on public budgets.
In conclusion, the Nuclear Energy Outlook's transformative scenario is a bold vision that requires a comprehensive and coordinated effort from OECD countries. While the challenges are significant, the potential benefits are immense. By embracing this scenario, we can not only reach the COP28 goal but also ensure a sustainable and resilient energy future for generations to come. It is a call to action that demands urgent attention and collaboration from policymakers, industry leaders, and the global community.
