"Fukushima: The Story of a Nuclear Disaster" is just that. The 9.0 Tohoku earthquake off the coast of Honshu Island, the main island of Japan occurred on 11 March 2011 at about 5:30am local time. The earthquake lasted some 6 minutes on the land closest to the earthquake and the tsunami, created by the quake, arrived some 50 minutes after the initial earthquake. The tsunami, 14 metres (46 ft) high overwhelmed the plant's seawall, which was only 10 metres (33 ft) high. The tsunami water flooded the low-lying rooms in which the emergency diesel generators were housed. They began to fail soon after and were replaced by emergency battery-powered systems. When the batteries ran out the next day on 12 March, active cooling systems stopped, and the reactors began to heat up. The power failure also meant that many of the reactor control instruments also failed. With no power and no way to cool the housing around the reactors, they produced hydrogen which concentrated with the air and caused multiple hydrogen-air explosions in Reactors 1,2 and 3 from 12 March to 15 March. When the hydrogen had to be evacuated from the reactor pressure vessel, explosions occurred in the upper secondary containment building in all three reactors. Therefore there were meltdowns of the fuel rods in Reactors 1, 2 and 3 and the top to floors of Reactor 4 were reduced to bare frames from another hydrogen-air explosion.The meltdowns of Reactors 1, 2 and 3 in the previous sentence were not in that order and were not nearly as simple as making a sentence. Unit 1 was the first priority of the management at Fukushima-Daichi, when the diesel generators being in the basement and underwater from the tsunami stopped operating, The battery backup kicked in and kept electricity available to most of the plants site. But only for a couple of hours and the battery backup power dwindled to zero. The management at Plant Fukushima was now on its own to keep further destruction from occurring. The systems operations manual on restoring power after a failure of this type had ended when the power of the battery backups ended. The plant manager at Fukushima was Masao Yoshida, who thought the first explosion in Reactor 1 was another strong aftershock, then came the news that the top of the Unit 1 reactor building had blown off- this was still within the outer containment dome. a check of the water level around Unit 1 showed that it was about 5 feet below the top of the fuel. The melting of the fue had started about twenty hours previously. They had received three strikes on the first batter and there was one out. Now batter number two swung and missed- the emergency response center had been working for hours to lay an insulated cable on the ground and were within minutes of connecting the cable to restore power to units 1 and 2. Falling debris from the explosion had damaged that cable and also damaged the firehoses that the workers had put in pplace to inject sea water into Unit 1. The government operations response to the disaster was now at the prime ministers level. They were having trouble keeping the media and therefore the country aware of the continuing story.
The Authors of Fukushima, the book, are the three named authors Lockbaum, Lyman, and Stranahan and the Union of Concerned Scientists. These scientists have a good knowledge of the workings of a nuclear power plant and they have a theoretical knowledge of how the metals and other chemicals react to produce nuclear energy generation along with the knowledge of which elements create the deaddly radiation that is normally contained in the reactor itself. Ground was broken for the first nuclear reactor at Fukushima in July, 1967 will General Electric as the supplier and main contractor. TEPCO (Tokyo Electric Power Company) was the owner of the generation at this site and the largest supplier of electricity in Japan. They would choose GE to build the other five nuclear reactors at Fukushima-Daiichi and two of the four at Fukushima-Daini. There are two main types of nuclear reactors for generating electricity- they are the Boiling Water Reactor (BWR) and the Pressurized Water Reactor (PWR). The plants were to become a financial bonanza for the local communities and cities around these plants because they supplied the greater majority of the taxes these cities and towns used to operate. They also provided more than enough laborers to create full employment in the areas. There is a massive system of fault lines criss-crossing the islands of Japan and make it the country with the most earthquakes. the designers of the power plants had to make them extra strong to survive in tact from the very strongest earthquakes. But the companies who had the plants designed seemed to take the mostly likely strongest earthquakes and not the uniquely strongest earthquakes. In the Japanese language this often meant 90-95 percent of the strongest earthquake. The government officers who regulated the power companies and therefore regulated their nuclear power plants appeared to have a good cooperative working relationship with the power company officers and designers. It was much like the U.S. Congress and the private companies and individuals who befriend congressmen and give aid and advice for creating the laws Congress makes. With the Japanese these close working relationships seemed to sometimes bend the rules so that a plant construction project could come into fruition for a few dollars less. The story grows more unpredictable as the disaster moves from bad to worse, and the safety systems with backups for the backups failed like dominoes in a row.
The evacuation zone around Fukushima-Daiichi and Fukushima-Diani was now a ten mile semicircle around both plants and people in those areas were relocated. Seven or eight days into the disaster, relations between Japan and the U.S. tightened up again when the NRC was wanting the evacation extended from twenty kilometers to thirty kilometers. The U.S. reasoning was that Uniit 4 Reactor at Fukushima-Daiichi was still not under complete control and could still infuse radioactive material into the atmosphere and be blown over a wider area while Japan said that was highly unlikely and the increase in the largeer ara would add more unsettlement to the Japanese public. The results of this disaster are still in active study four years after the disaster has been contained to the ground area of Fukushima-Daiichi and a contaminated area around the plant. There is no measureable radioactivity coming from the plant site. The government and TEPCO received great criticism for not building the plannts more robust, for not building the 10 meter seawall to 15 meters and placing the diesel generators in the basement. The government of Japan and Tepco say on the other hand that no one could project an earthquake of magnitude 9.0 Mw {1} and a tsumami 50 feet high at the Fukushia Daiichi location and that these two events were the cause of the disaster at that location. These discussions will continue until a such time as they are no longer relevant to either party or until the next large nuclear power disaster occurs. There were several other reviews of this book which I read before finishing this book and a common objection in most of those reviews the writers thought the first part of the book which deals with the actual earthquake, tsunami, and nuclear meltdowns were well written and interesting but that the latter half discussed the various agencies, their reason-to-be and their opinions were too esoteric to be included in this book and signified a black mark on the story. I disagree with that theory.
"On 10 March 2015, a Japanese National Police Agency report confirmed 15,891 deaths, 6,152 injured, and 2,584 people missing across twenty prefectures, as well as 228,863 people living away from their home in either temporary housing or due to permanent relocation."{2}
