Super Critical Water Reactors GIF System Steering Committee

The Super Critical Water Reactors System Steering Committee (SCWR SSC) was initially formed following the signing of the SCWR System Arrangement in 2006. This FA expired in early 2025. A new SCWR FA has been proposed under the current 2025 GIF FA. It will become effective once three signatories are gathered. The resulting committee goal is to supervise four projects encompassing a wide array of subjects pertaining to Super Critical Water Reactors. The SCWR is the only water cooled reactor among the six Generation IV systems and is a relatively evolutionary approach from current light water reactors (LWRs) that compose the majority of the reactors operated today, it also benefits from the experience of modern fossil fueled plants that rely on a energy conversion system using super-critical water.

DISCLAIMER: The entry into force of the 2025 GIF Framework Agreement on 1st March 2025 brings changes to the GIF membership. The website will be updated in due course to reflect these changes.
