The GIF Proliferation Resistance and Physical Protection (PR&PP) evaluation methodology has been developed for GEN IV nuclear energy systems under the international consensus. The PR&PP WG activities include development of the measures and metrics; establishment of the framework of PR&PP evaluation, the demonstration study using Example Sodium Fast Reactor (ESFR), which included the development of three evaluation approaches; the Case study using ESFR and four kinds of threat scenarios; the joint study with GIF System Steering Committees (SSCs) of the six reactor design concepts; and the harmonization study with the IAEA's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO). This paper reviews the status of GIF PR&PP studies and identifies the challenges and directions for applying the methodology to evaluate future nuclear energy systems in Japan.
