COVID-19 IMPACT

Pandemic decreased the market demand

The COVID-19 pandemic has had significant impacts on various industries worldwide, including the energy sector and Generation IV reactor market share. The pandemic has disrupted R&D activities across many sectors. Depending on the severity and duration of the disruptions, it is possible that research and development efforts for Generation IV reactors could have been delayed or slowed down. This could potentially impact the timeline for prototype development and commercial deployment. Economic uncertainty and shifting priorities during the pandemic may have affected funding and investment in the nuclear industry. Governments and private investors may have reassessed their financial commitments, which could have implications for the pace of development and deployment of these advanced reactors. The pandemic forced many regulatory bodies to shift their focus and resources towards addressing the immediate health crisis. This diversion of attention could have affected the regulatory processes and approvals necessary for the licensing and deployment of new nuclear technologies.

LATEST TRENDS

Innovations in nuclear fuel cycle to fuel the growth in the market

Innovations in the nuclear fuel cycle are playing a significant role in shaping the future of the nuclear power industry, including the Generation IV reactor market. These advancements aim to enhance the sustainability, efficiency, and safety of nuclear power generation. One area of innovation is advanced fuel designs. Researchers are exploring fuel options that offer higher burnup rates, improved thermal performance, and increased resistance to degradation. These designs can potentially enhance the fuel utilization efficiency of Generation IV reactors, leading to reduced waste generation and longer fuel lifecycles. Another aspect of innovation is the development of recycling options for nuclear fuel. Technologies such as advanced reprocessing techniques and advanced fuel cycles, including concepts like pyro processing and molten salt fuel cycles, are being explored. These approaches aim to extract more energy from nuclear fuel and reduce the amount of long-lived radioactive waste. By incorporating these innovative fuel cycle technologies, Generation IV reactors have the potential to achieve higher fuel efficiency, reduce waste production, and utilize nuclear resources more effectively.

• As of 2024, there are three commercial‑scale Generation IV reactors in operation (two BN‑series sodium‑cooled fast reactors in Russia totalling 1 480 MWe and one CFR‑600 reactor in China at 600 MWe), supplemented by six demonstration reactors (four in China, one in India, one in Russia) and one prototype under construction in Russia

• Established in 2001, the Generation IV International Forum (GIF) unites 13 countries plus Euratom (representing 27 EU member states) to coordinate R&D on six selected reactor technologies—SFR, LFR, MSR, GFR, SCWR and VHTR—with a collective goal of industrial deployment by 2030, according to the GIF portal.

DRIVING FACTORS

Energy security and independence to foster the market growth

The drive for energy security and independence is a significant driving factor in the Generation IV reactor market. Many countries aim to reduce their reliance on imported energy sources, which can be vulnerable to geopolitical tensions or supply disruptions. Generation IV reactors offer the potential for domestically sourced, reliable electricity generation, thereby enhancing energy security. By reducing dependence on fossil fuels, countries can diversify their energy mix and mitigate risks associated with fluctuating fuel prices and geopolitical instability, ensuring a more stable and self-sufficient energy supply.

• On May 23, 2025, the U.S. issued four Executive Orders aimed at “Deploying Advanced Nuclear Reactor Technologies for National Security,” “Reinvigorating the Nuclear Industrial Base,” “Reforming Nuclear Reactor Testing,” and “Ordering the Reform of the Nuclear Regulatory Commission,” to accelerate Gen IV deployment—according to the White House Presidential Actions.

• The U.S. Department of Energy launched the Advanced Reactor Demonstration Program on May 14, 2020, with an initial $230 million in cost‑shared R&D awards to support two first‑of‑a‑kind Gen IV reactor demonstrations—according to DOE.

Waste management and reduced environmental impact to result in the expansion of the market

Effective waste management and reduced environmental impact are crucial considerations in the development of Generation IV reactors. These advanced reactors aim to minimize the volume and toxicity of nuclear waste through innovative fuel cycle technologies, such as recycling and transmutation. By recycling nuclear fuel and utilizing advanced materials, Generation IV reactors can significantly reduce the long-term environmental impact of nuclear power generation. The ability to address waste management concerns and reduce environmental impact is a driving factor for countries seeking sustainable and environmentally friendly energy options in the face of climate change and increasing waste disposal challenges.

RESTRAINING FACTORS

Regulatory and licensing challenges to hamper the market growth

The regulatory framework for nuclear energy, including the licensing process, can present challenges for the deployment of Generation IV reactors. The regulatory authorities need to develop new frameworks or modify existing ones to address the unique characteristics and safety features of these advanced reactors. Delays in regulatory processes or the absence of clear guidelines can hinder project timelines and increase costs.

• Over 90 percent of global HALEU supply originated from Russia prior to 2022; subsequent geopolitical disruptions pushed U.S. domestic HALEU production facilities out to 2027, delaying fuel availability by at least 3 years for advanced reactor projects—according to Reuters.

• In its May 2025 proposal, the U.S. administration cut approximately $400 million from the DOE Office of Nuclear Energy’s FY 2026 budget—primarily reducing funding for non‑essential nuclear R&D—potentially slowing progress on Gen IV reactor initiatives.
