On March 10, 2024, the first World Nuclear Energy Summit (WNES) convened in Paris. The French Government joined forces with the International Atomic Energy Agency (IAEA) to set the stage for this high-level gathering. Peaking at over 180, the summit brought together heads of state and leaders from over 60 countries. Collectively, their first priority was increasing the role of nuclear energy in global decarbonization efforts.
During the summit, participants engaged in discussions about financing models, fuel supply security, and the development of skilled workforces necessary for advancing nuclear energy initiatives. The WNES highlighted the need for global collaboration to make up for a significant gap in current aspirations for nuclear power generation by 2050.
The event celebrated the addition of four new countries—Belgium, Brazil, China, and Italy—to the Declaration to Triple Nuclear Energy. This declaration, which was first released in 2023, is remarkable for having a total of 38 signatories, at the time of writing, committed to building more nuclear energy capacity around the world.
Key Discussions on Financing and Workforce Development
Leaders at the WNES highlighted that meeting the goal of tripling nuclear energy production by 2050 necessitates strong international cooperation. From finance, technology, and energy, they underscored the need for enabling policy environments. Access to finance is critical not just to have built new nuclear plants.
The summit was a vibrant place for discussing new financing models to lower costs for developing nuclear energy. Conversations focused on where the opportunities are to mobilize private capital while using sovereign backing to address early-stage risks.
“To consider developing frameworks to mobilise private capital where sovereign backing helps to mitigate early-stage risks and incentivise private finance stakeholders to participate,” – Collective statement from summit leaders.
The skill gap Attendees talked about the immediate need for a skilled workforce that can help ramp up state and federal nuclear energy efforts. Making the development of our workforce a priority is essential. It lays the foundation for countries to meet their growing energy needs while transitioning to low-carbon, more sustainable energy sources.
Enhancing Safety and Security Standards
Safety, security, and non-proliferation were central topics of the summit’s discussions given their importance in guiding global cooperation in the nuclear energy space. Leaders understood well the need to maintain these principles as countries look to expand their use of nuclear energy.
IAEA Director General Rafael Mariano Grossi stated that for nuclear energy to be a viable option, it must be investible. He underscored the importance of keeping predictable policies and resilient supply chains in place. Accessible financing is another key component to reduce costs and scale up nuclear energy’s deployment.
“Nuclear power is not simply a nice-to-have, or a cleaner option. It is a strategic opportunity and we know it.” – Rafael Mariano Grossi
French President Emmanuel Macron has been a vocal advocate for countries and manufacturers alike to embrace standardization. One example he highlights is the need to develop harmonized safety and operational standards. He acknowledged that this method would go a long way toward minimizing expenses and hindering the deployment of nuclear power with delays.
“We need to standardise as much as possible between countries and manufacturers – to establish standards in terms of capacity, energy producers and countries. This is key to reducing costs and delays and ensuring that nuclear power will be part of the energy transition.” – Emmanuel Macron
The Role of Nuclear Energy in a Decarbonized Future
The conversations at WNES further instilled my conviction that nuclear energy is an essential partner in reaching the UN Sustainable Development Goals. Leaders advocated that as countries strive for electrification, digitalization, and advancements in technology such as artificial intelligence, reliable and predictable energy sources are essential.
In his speech, Grossi noted that nuclear energy is one of those dependable solutions. He emphasized its potential to contribute to a stable, low-carbon energy system while addressing global challenges such as climate change.
“When we speak about development, we speak about electrification, digitalisation and artificial intelligence; in all these areas, we will need reliable and predictable answers. Nuclear energy is one of those answers.” – Rafael Mariano Grossi
Macron made the case for nuclear power as a driver of advancement and prosperity. He highlighted its capacity to align global competitiveness, reducing CO2 emissions and increasing energy independence.
“Nuclear power is a source of progress and prosperity because it is a source of energy, particularly for electricity generation, which allows us to reconcile three objectives that are central to our ambitions.” – Emmanuel Macron
