[en] Open literature based research about evacuation planning and the preparedness for nuclear emergency was performed, focusing on the following issues; a) Reflex action phase and evacuation in France, b) Research on analytical models and database of evacuation time estimation (ETE) by practical examples in U.S. Reflex action phase introduced in France is a prompt shelter-in-place is requested in the case of accidents liable to cause radioactive release within a short period. Subsequent evacuation is conducted after the passage of the radioactive plume. Pre-distribution of stable iodine tablets to the populations living in this area is required to this prompt sheltering. In the case of evacuation at nuclear emergency, evacuees are transported to public reception centers by buses in France, as same as in Japan. The public reception center is selected from facilities where are outside of the sheltering area, that is, the area outside 10km radius in the case of nuclear power plant accident. According to examples of ETE report for commercial nuclear power plant licensing in U.S., ETE have to be conduct for external conditions, season, day of week, time of day, Weather (Good, Rain, Snow), and special or annual main events. ETE should be done to pre-defined evacuation regions. A telephone survey of residents within the EPZ is conducted to gather focused data needed for ETE study that were not contained within the census database. It is very important for ETE to consider a portion of the population outside the impacted region will elect to voluntary evacuate, so called, 'voluntarily evacuation' or 'shadow evacuation'. Furthermore, traffic simulation technology development for large scale road network composed of main and small roads, is very important in Japan. (author)
