Workshop on Non-Electric and Hybrid Applications of Nuclear Energy (NEANH 2024 Workshop)
The Generation IV International Forum (GIF) Task Force on Non-Electric Applications of Nuclear Heat (NEANH) and the Korea Atomic Energy Research Institute (KAERI) co-organised the Non-Electric and Hybrid Applications of Nuclear Energy Workshop on April 26, 2024, in Busan, Korea. The event was hosted by the Korean Nuclear Industry Association (KAIF) and the Korea Nuclear International Cooperation Foundation (KONICOF) on the margins of the 39th Korea Atomic Power (KAP) Annual Conference.
Overview of the event
This Non-Electric and Hybrid Applications of Nuclear Energy Workshop included approximately 75 participants from around the world, and featured participation from international organisations collaborating on exploring the opportunity for NEANH, energy end-users in hard-to-abate industrial sectors, regulators, and nuclear technology developers targeting non-electric applications. Participants shared information on specific needs, requirements, and potential challenges or concerns associated with coupling nuclear energy to industrial applications in pursuit of advancing technologies toward a net zero future.
The event featured the following sessions:
- Session 1: Historic context and overview of ongoing international efforts
- Session 2: Industrial end-user perspectives
- Session 3: Operational experience and the challenges associated with operating a co-located system
- Session 4: Panel with nuclear technology developers targeting non-electric applications.
- Session 5: Interactive discussion on the topics discussed, and next steps.
The day’s discussion followed Chatham house rules, and comments are hence included in the proceedings without attribution, unless permission was explicitly provided. The event featured simultaneous interpretation between English and Korean, and presentations were delivered in both languages.
This 2024 Workshop follows the first NEANH Workshop in Toronto, Canada in October 2022 and supports the NEANH Task Force’s efforts to enhance the general level of knowledge on non-grid applications of nuclear systems, highlight system configurations that are relevant for further investigation, and to develop a network to the high temperature community outside the nuclear field to inform systems analysis on non-electric applications of nuclear heat.
Key Insights from the Workshop
- There is a useful history of nuclear energy being used for non-electric applications, but this is limited to lower temperature applications using LWR technologies. Higher temperature industrial applications have different considerations and may benefit more from GenIV reactor technology.
- At higher temperatures, fuel switching industrial processes is challenging and requires significant alterations to existing processes. Integrated systems analysis and financial support are likely required to enable this transition.
- The heat and electricity demand from the decarbonisation of the industrial sector will be significant.
- Reports and tools exist to help end-users assess the opportunity for their operations, but increased engagement is encouraged.
- It is a significant opportunity to use nuclear energy to reduce emissions in industrial sectors, and end users would deploy nuclear energy today if they were commercially available.
- Hydrogen production is of particular interest, and value chain analysis is required to understand the competitiveness of nuclear energy.
- There is regulatory uncertainty for NEANH, and systems will require a case-by-case analysis using a risk-informed and graded approach. There are no obvious barriers that cannot be overcome.
- The opportunity for NEANH is geographically distinct due to unique regulatory landscapes, domestic policies, availability of alternative energy options, and supply chain capabilities.
- Increased collaboration beyond the nuclear sector is essential, including to communicate progress in this area. Communication and transparency are important to build confidence among regulators, investors, and the public.
- Future workshops should also include end users, and other impacted stakeholders such as financiers, investors, and insurers.
