Life is filled with work and home obligations, errands to run and to-do lists that never seem to get done. And yet, some people seem to be unaffected by it all. A house can be on fire on one side of them and an earthquake on the other and they still seem calm and collected.
As the reactors were unable to generate power to run their own coolant pumps, emergency diesel generators came online, as designed, to power electronics and coolant systems.
These operated nominally until the tsunami destroyed the generators for Reactors 1—5. The Chernobyl outline essay example generators cooling Reactor 6 were undamaged and were sufficient to be pressed into service to cool the neighboring Reactor 5 along with their own reactor, averting the overheating issues that Reactor 4 suffered.
These pumps needed to continuously circulate coolant water through a Generation II reactor for several days to keep the fuel rods from melting, as the fuel rods continued to generate decay heat after the SCRAM event.
The fuel rods would become hot enough to melt during the fuel decay time period if an adequate heat sink was not available. After the secondary emergency pumps run by back-up electrical batteries ran out, one day after the tsunami, 12 March,  the water pumps stopped and the reactors began to overheat.
Meanwhile, as workers struggled to supply power to the reactors' coolant systems and restore power to their control roomsa number of hydrogen-air chemical explosions occurred, the first in Unit 1, on 12 March and the last in Unit 4, on 15 March.
The pressurized gas was vented out of the reactor pressure vessel where it mixed with the ambient air, and eventually reached explosive concentration limits in Units 1 and 3. Due to piping connections between Units 3 and 4, or alternatively from the same reaction occurring in the spent fuel pool in Unit 4 itself,  Unit 4 also filled with hydrogen, resulting in an explosion.
In each case, the hydrogen-air explosions occurred at the top of each unit, that was in their upper secondary containment buildings. The full extent of the movement of the resulting corium is unknown but it is now considered to be at least through the bottom of each reactor pressure vessel RPVresiding somewhere between there and the water-table below each reactor.
In a similar manner to what was observed at reactor 4 in Chernobyl. As of Septemberthere has been one confirmed fatality linked to short term overexposure to radiation reported due to the Fukushima accident,  while approximately 18, people died due to the earthquake and tsunami.
The maximum cancer mortality and morbidity estimate according to the linear no-threshold theory is 1, and 1, but with most estimates considerably lower, in the range of a few hundred. The risks from a number of additional radiation-induced cancers are also expected to be elevated due to exposure caused by the other low boiling point fission products that were released by the safety failures.
Inthe number of thyroid cancers or detections of developing thyroid cancers numbered The exact causes of the majority of these evacuation related deaths were not specified, as according to the municipalities, that would hinder application for condolence money compensation   by the relatives of the deceased.
The report also found that the Fukushima Daiichi Nuclear Power Plant was incapable of withstanding the earthquake and tsunami. TEPCO, the regulatory bodies NISA and NSC and the government body promoting the nuclear power industry METIall failed to correctly develop the most basic safety requirements—such as assessing the probability of damage, preparing for containing collateral damage from such a disaster, and developing evacuation plans for the public in the case of a serious radiation release.
Fukushima is in the 50 hertz Tohoku region.
