The death toll of the Fukushima nuclear accident dominated headlines for weeks after the event and overshadowed the much larger tragedy that happened at the same time and place: the Tsunami killed 15,893 people, more than 25 times the number from the nuclear accident. However, the original design considerations did not provide comparable safety margins for extreme external flooding events, such as tsunamis.Despite the efforts of the operators at the Fukushima Daiichi nuclear power plant to maintain control, the reactor cores in units 1-3 overheated, the nuclear fuel melted and the three containment vessels were breached. Electrical switchgear was also disabled. Responses were submitted to the government in November.In August 2014 the Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF) was set up by government as a planning body with management support for R&D projects, taking over IRID’s planning role. Tepco accepted the conditions imposed on the company as part of the package. In May 2015 its final report was delivered to member states, and was published in September. The 2013 Japan trade deficit was JPY 11.5 trillion.In May 2011 a team of 18 experts from 12 countries spent a week at the plant on behalf of the International Atomic Energy Agency (IAEA), and that mission's final report was presented to the IAEA Ministerial Conference in Vienna in June. Initially cooling would have been maintained through the main steam circuit bypassing the turbine and going through the condensers.Then 41 minutes later, at 3:42 pm, the first tsunami wave hit, followed by a second 8 minutes later.
At 9.23 pm the Prime Minister extended this to 3 km, and at 5.44 am on 12th he extended it to 10 km. It included a new goal of cutting the amount of groundwater flowing into the buildings to less than 100 mHowever, Tepco’s latest roadmap shows fuel removal from the pond at unit 1 is now expected FY27-28, and from unit 2 FY24-FY26. It also summarised radioactive releases and their effects.Meanwhile a July 2011 report from MIT's Centre for Advanced Nuclear Energy Systems provided a useful series of observations, questions raised, and suggestions. Discussion was ongoing, but action minimal. "The most important health effect is on mental and social well-being, related to the enormous impact of the earthquake, tsunami and nuclear accident, and the fear and stigma related to the perceived risk of exposure to radiation." This assumption was accepted by nuclear power plant operators and was not challenged by regulators or by the government. The main problem initially centred on Fukushima Daiichi units 1-3. It received JPY 7 billion ($91 million) in public funds as well as a total of JPY 7 billion from 12 nuclear plant operators, the Tepco share of JPY 2379 million ($30 million) being largest. The average compensation for real estate was JPY 49.1 million ($490,000), JPY 10.9 million ($110,000) for lost wages, and JPY 30 million ($300,000) as “consolation money” for pain and suffering. Tepco said it appreciated the chance to 'transform to New Tepco'.The government and 12 utilities are contributing funds into the new institution to pay compensation to individuals and businesses claiming damages caused by the accident. At 3.36 pm on Saturday 12th, there was a In unit 1 most of the core – as corium comprised of melted fuel and control rods – was assumed to be in the bottom of the RPV, but later it appeared that it had mostly gone through the bottom of the RPV and eroded about 65 cm into the drywell concrete below (which is 2.6 m thick). The venting was designed to be through an external stack, but in the absence of power much of it apparently backflowed to the service floor at the top of the reactor building, representing a serious failure of this system (though another possibility is leakage from the drywell).
