The work of GIF on each of the six Gen-IV systems is governed by Systems Arrangements (SAs) or Memoranda of Understanding (MoU) that establish respectively System Steering Committees (SSCs) and provisional SSCs (pSSCs).
The SSCs report directly to the GIF Policy Group (PG), are in close communication with the Experts Group (EG) and are supported by the GIF Technical Secretariat (TS). They also provide input and can require support from Methodology Working Groups that look into cross cutting topics. Each SSC oversees several projects.
