This study is carrying out R&D of margin assessment methodology of decay heat removal function for sodium-cooled fast reactors against external hazards in the MEXT innovative nuclear system R&D project from 2012 to 2016. In 2014, the development has been completed for hazard evaluation and event sequence evaluation methods against external precipitation and volcanic eruption hazards. In forest fire, a hazard evaluation methodology has been developed using fire spread simulations.
