According to the World Nuclear Association, “The reactors proved strong seismically, however weak to the tsunami. Power, from grid or backup mills, was accessible to run the residual warmth removing (RHR) system cooling pumps at eight of the eleven models, and regardless of some issues, they achieved ‘chilly shutdown’ inside about 4 days. The different three, at Fukushima Daiichi, misplaced energy at three.42 PM, nearly an hour after the earthquake, when your complete website was flooded by the 15-metre tsunami. This disabled 12 of 13 back-up mills on website and likewise the warmth exchangers for dumping reactor waste warmth and decay warmth to the ocean. The three models misplaced the power to take care of correct reactor cooling and water circulation features. Electrical switchgear was additionally disabled”.
