GIF Research and Development Outlook for Generation IV Nuclear Energy Systems - 2018
The 2018 R&D Outlook for Generation IV Nuclear Energy Systems from the Generation IV International Forum (GIF) reviews advancements and challenges in the nuclear sector since the 2009 GIF R&D Outlook. Focused on addressing safety concerns post-Fukushima, economic and regulatory uncertainties, and construction challenges for new facilities, GIF emphasizes ongoing R&D and methodology development.
GIF operates as a multinational cooperative, driving R&D to demonstrate the feasibility and enhance the performance of next-generation nuclear systems. These aim to improve sustainability, safety, reliability, economics, proliferation resistance, and physical protection. Innovations in reactor designs intend to reduce costs and open new markets like hybrid energy systems, using high-temperature coolants like helium and supercritical water to increase thermal efficiency by up to 40% and enable industrial applications, significantly cutting fossil fuel use.
Key achievements include developing advanced fuel cycles that optimize uranium use and reduce waste toxicity. These efforts align with stringent safety standards for new nuclear plants. GIF also focuses on dispatchable energy to complement renewables, supporting institutional innovation globally by defining safety standards for advanced reactors, including sodium-cooled fast reactors.
The 2018 report notes variations in funding and priorities across GIF member countries, affecting the progress of the six identified nuclear energy systems. This discrepancy prompted timeline revisions in the 2014 Technology Roadmap Update. The 2018 update assesses progress against these objectives, identifies remaining challenges, and outlines necessary R&D to advance the demonstration and deployment of Gen IV systems.
This update thus details GIF’s strategic directions amidst evolving global energy needs and technological developments, aiming to position advanced nuclear technology at the forefront of future energy solutions.
