This document by the Proliferation Resistance and Physical Protection Working Group (PRPPWG) of GIF examines various siting options for advanced modular reactors (AMRs) and microreactors and implications for proliferation resistance and physical protection. The report considers the following four siting options for AMRs: 

  • remote locations,
  • near population centres,
  • floating or underwater power stations, and
  • civilian marine propulsion. 

Additionally, it explores five crosscutting considerations: Single versus multi-modules, ultimate heat sink, autonomous and remote operation, high assay low enriched uranium (HALEU) versus low enriched uranium (LEU), and transit of reactors. Each section concludes with key findings and high-level conclusions are consolidated at the end of the report.
