Preparing the Future through Innovative Nuclear Technology - Outlook for Generation IV technologies - 2018

The 2018 R&D Outlook for Generation IV Nuclear Energy Systems, produced by the Generation IV International Forum (GIF), addresses developments and hurdles in nuclear technology since the 2009 R&D Outlook. GIF's collaborative international effort focuses on innovative nuclear systems that enhance safety, sustainability, and efficiency.

Challenges in nuclear energy include safety concerns post-Fukushima, regulatory uncertainties, market distortions from low gas prices and renewable subsidies, and construction delays. Despite these challenges, GIF progresses in R&D aimed at improving nuclear technology through the deployment of advanced reactors and fuel cycles that offer substantial performance benefits over traditional technologies.

Key advancements include the use of high-temperature coolants, enhancing thermal efficiency and allowing broader industrial applications. Advanced reactors and fuel cycles promise improved uranium utilization and reduced waste radiotoxicity. These technological strides aim to integrate nuclear energy more effectively into the global low-carbon energy mix, supporting the transition to sustainable energy systems.

GIF's updated outlook also highlights the need for international cooperation in research and policy to facilitate the development and deployment of these advanced systems. It advocates for nuclear energy's role in achieving low-carbon goals and calls for increased policy support to foster the adoption of next-generation nuclear technologies. The report underscores the potential of nuclear innovations in meeting future energy demands while addressing environmental challenges.
