In their latest findings, Nuclear experts have appreciated the benefits of designing a structure with enough safety margins that have been noticed now as a Japanese nuclear power plant that is built closer to the epicenter of last year's devastating earthquake than Fukushima is found to be good structure and largely undamaged.

The research was carried out by a team of a U. N.'s nuclear watchdog, which has reported in its submissions that though the Onagawa plant situated in northern Japan suffered higher levels of ground shaking as compared to the Fukushima Dai-ichi, the structure is still unaffected and undamaged as it was well designed and built with proper safety margins too.

The last year's earthquake reached magnitude of 9.0 on the scale and gave Fukushima multiple meltdowns, which further triggered a massive tsunami that destroyed almost all around.

The above facts were revealed by Mr. Sujit Samaddar, among the 19-member that carried the International Atomic Energy Agency mission. He has further confirmed for running similar inspections at other plants also to share the same information and try to improve safety measures for all.

"Exposure levels were much lower than those reported in studies even several years after the Chernobyl incident," said Mr. Masaharu Tsubokura of the University of Toyko, lead author of a short paper published in the Thursday issue of the Journal of the American Medical Association.
