Beyond design basis accident have been evaluated in Joyo. Anticipated transient without scram, loss of reactor level and protected loss of heat sink are identified as main accident sequence group. Unprotected transient over power and protected loss of heat sink are selected as representative accident by the view point of frequency and impact. As the result of safety analysis of these accident, we confirmed that no beyond design basis accident reach to release a large amount of radioactive materials.
