The engineer says he moved offsite for a few days to a disaster-response building in the town of Okuma, 5 km away. But on 15 and 16 March 2011 the situation at Daiichi reached its most critical phase. A series of hydrogen explosions had left much of the complex a tangled mess of radioactive concrete and steel. Unit three had exploded, three reactors were in meltdown and over 1000 fuel rods [assemblies] in the reactor four building, normally covered under 16 feet of water, had boiled dry, raising the spectre of a nuclear fission chain reaction. In his darkest moments, Mr Yoshizawa admits he shared the same fear as other experts – that the crisis could also trigger the evacuation of the Fukushima Daini plant 10 km away. [...]
