English.news.cn 2011-05-15 14:19:34 – TOKYO, May 15 (Xinhua) -- Key facilities at the Fukushima No. 1 nuclear power may have been damaged by the quake itself that day rather than tsunami-caused power loss that failed the reactor's cooling function, Kyodo News quoted a utility source said Saturday.Data taken by workers entering the No. 1 reactor building at the crippled plant on the night of March 11 showing the radiation level was as high as 300 millisieverts per hour suggest a large amount of radioactive materials from nuclear fuel in the reactor was already released.
The findings may call for a review of preparedness against quakes at various nuclear power stations in Japan as they have primarily focused on securing auxiliary power supplies and embankment enhancement against tsunami after the Fukushima plant crisis, assuming that reactor facilities at the plant were unscathed by trembling.
