Our government has been telling they would restart any nuclear power plant once Nnuclear Regulation Authority:NRA judges it as legitimate according to their regulation. NRA declares they won't guarantee its safety if they legitimize it. They insist they just judge it regulated properly. Our government says, however, NRA would guarantee the safety. Both of them, especially our government, are trying to avoid the responsibility for the safety issue.
In case of any serious accident at nuclear power plant, an actual serious problem is how the local people could evacuate from collapsed nuclear power plant. Compared with the plate type earthquake, an mega earthquake directly above the focus is known to damage the roads around there even more frequently. It would deprive the people there of the way to evacuate from the radio active substance contamination. Evacuation is supposed to be planned by the local government. Either central government or NRA won't concern about it. There is no financial and technical capability to plan for their evacuation in local governments. Evacuation of the people is abandoned from the beginning
Of 54 nuclear power plants in Japan, 5 are located in the Kansai Hokuriku area. They have 13 reactors in total. Here is the map, although it is described in Japanese. All of them are within 50km of distance. A mega earth quake could damage multiple reactors of these 13. Or a domino effect could cause serious accidents to all of them.
There is only one trunk road to those plants. It is highly suspected that this route could be damaged by the earthquake or tsunami. It means that there would be no way to have the people evacuated or to rescue and manage the damaged plants.
The large cities like Kyoto and Osaka are located within 100km in radius from those nuclear power plants. There could be serious radio active substance contamination over these areas. We should remember, in the case of Fukushima, most of radio active subvstances have flown away to the Pacific ocean with the land spared with the contamination. If Kyoto and Osaka areas are highly contaminated, there would be tens of millions people evacuated from there. I guess it almost means our country won't survive any longer.
