World Nuclear Association Launches Roadmap to Mainstream Finance as First Module of World Nuclear Investment Guide

As governments, industry and energy users accelerate efforts to at least triple global nuclear capacity by 2050, one challenge has emerged as critical to success: financing. While nuclear energy is increasingly recognised as essential for energy security, economic competitiveness and decarbonisation, achieving global ambitions will require investment to scale far beyond current levels. 

Today, World Nuclear Association is launching Roadmap to Mainstream Finance: The Path to Scale Nuclear Energy, the first module of the inaugural World Nuclear Investment Guide. The roadmap sets out how nuclear can evolve from a bespoke, government-led financing proposition into a mainstream infrastructure asset class capable of attracting broad institutional investment. 

A $6 Trillion Investment Opportunity 

The Roadmap highlights the scale of the opportunity ahead. Global demand for nuclear energy is real; Governments have collectively set targets for 1,446 GWe of nuclear capacity to be operating by 2050, more than triple today's installed capacity, and are deploying significant public resources to kick-start capacity growth in markets worldwide. Meeting governments’ ambitions will require approximately $6 trillion of cumulative investment by 2050. Finite government resources create a significant opportunity for investors and financial institutions to guide capital allocation in the market. Government programmes designed to support competitive and affordable nuclear infrastructure are naturally seeking to increase market crowding-in levels as the industry delivers to its economic and financial scaling targets. Most of this investment will be directed towards new nuclear generating capacity, but significant investment will also be required across the wider value chain, including fuel services and back-end capabilities that must scale too. 

The challenge is not a lack of capital. Rather, it is creating the conditions, confidence and financial frameworks necessary to attract larger pools of private capital and accelerate financial decision making all around the world. 

Closing the Gap Between Nuclear and Finance 

The World Nuclear Investment Guide is designed to address a longstanding structural gap between the nuclear and financial communities. Nuclear projects are often viewed as complex, bespoke investments with limited comparable data and few standardised frameworks for assessment. As a result, many investors and financial institutions remain unfamiliar with the sector despite growing interest in clean energy and infrastructure opportunities. 

Developed with strategic support from an Advisory Panel of senior nuclear and finance leaders, and a member-driven Task Force, the Guide aims to create a shared understanding of risk, opportunity and investment requirements. It reflects World Nuclear Association’s sustained engagement with both sectors through initiatives such as the Financing Nuclear Briefing Series (FNBS).  It will provide financially focused, practical tools that help investors better understand the nuclear sector while enabling project developers and governments to become more investment ready. 

The Guide: 

• Quantifies investment requirements across the nuclear value chain and key regions. 
• Builds financial literacy across the nuclear sector and nuclear literacy across the financial sector. 
• Provides practical frameworks and tools to support transactions and accelerate decision-making. 
• Helps establish more standardised approaches to evaluating and financing nuclear projects. 
• Fosters a common language between developers, governments, financial institutions and investors. 

Rather than offering investment advice, the Guide seeks to improve understanding and reduce barriers to investment, helping both sectors engage more effectively and systematically with one another. 

Six Conditions for Mainstream Finance 

The Roadmap identifies and details six structural conditions that will help nuclear transition towards mainstream finance and unlock access to larger pools of capital. These are: 

1. Institutional support: improved coordination between government, regulatory and industry bodies to raise investor confidence. 

2. Business standardisation: replicable technological designs, project structures, contractual arrangements and financial templates that reduce financial complexity. 

3. Priceable risk and reward: clearly identified and allocated risks that investors can independently assess and finance. 

4. Nuclear remuneration: market mechanisms that capture the full benefits of nuclear generation, incentivising investment at appropriate levels in each market. 

5. Supply chain capacity: political and market signals incentivising industrial capacity, skills and delivery capability to deliver full scale economics. 

6. Maturity transformation: nuclear financing backstop mechanisms and capacity to improve visibility on fair capital recovery and risk-adjusted return levels to support broader commercial market participation. 

The Roadmap emphasizes that these conditions are not unique to nuclear. Similar transitions to industrial scale have been achieved in sectors such as solar energy, offshore wind, LNG and other capital-intensive infrastructure industries.  

The Roadmap also provides practical recommendations for the role of key stakeholder groups (government, nuclear industry, financial institutions) to enable the transition from bespoke first-of-a-kind projects to a mainstream energy infrastructure asset class. 

Capturing Financial Interest and Capacity Through Global Engagement 

The launch of the Roadmap builds on more than a year of engagement between World Nuclear Association and the financial community. Through the Financing Nuclear Briefing Series, senior representatives from financial institutions, project developers, policymakers and industry organisations have come together to discuss shared challenges and opportunities in nuclear finance. Topics have included financing channels, fleet deployment models and the cost of capital required to support nuclear growth and achieve scale economics.  

The Roadmap has been shaped through the contribution of the Nuclear Investment Guide Advisory Board and Task Force (established through the Economics, Law and Financing Working Group). Drawing on expertise from across the nuclear, finance, legal, advisory and international policy communities, members have provided strategic guidance, expert review, challenge, practical examples and independent oversight to help ensure the Guide addresses the needs of the financial community and supports the development of more replicable nuclear financing models.  

Contributors have brought perspectives from a wide range of organisations, including Accenture, Arup, BNP Paribas, Cameco, CIBC Capital Markets, Denk Nuclear AG, EDF, Etara, the European Investment Bank (EIB), Export Development Canada (EDC), EY, GE Vernova, HSBC, the International Atomic Energy Agency (IAEA), , KEPCO, KPMG, La Caisse, Newcleo, , Pillsbury, Roland Berger, Rosatom, Rothschild & Co, Segra Capital Management, Sizewell C, the United Nations Economic Commission for Africa (UNECA), Uranium Energy Corp, URENCO, Vattenfall, White & Case LLP,  and Stifel, alongside a number of independent contributors. 

These discussions and contributions have reinforced a central message: closer and more systematic cooperation between the nuclear and finance communities is needed to bridge knowledge gaps, standardise approaches and enable the market conditions required for investment at scale. 

Looking Ahead to the Full Investment Guide 

The Roadmap marks the next step in a broader programme of work.  

The full Guide will be formally launched at the Finance Summit during the World Nuclear Symposium, where financial institutions, development banks, investors and industry leaders will convene to discuss the capital flow and partnership opportunities emerging worldwide in the nuclear investment pipeline.
