Hi, need to submit a 1750 words paper on the topic Japanese Earthquake and Tsunami: Fukushima. When the earthquake happened, all the nuclear reactors at the Fukushima plant automatically went off. Within a few seconds following the earthquake, the control rods were inserted in the core, which stopped the nuclear chain reaction. At this moment, the NISA (2011) notes that the cooling system was to take away the residual heat. this is about 7% of total power heat load on normal operation. However, this was not a normal operation. The earthquake damaged the external power supply of the Fukushima nuclear reactor.&nbsp. This was a difficult accident for any nuclear plant, and such incident is referred as “loss of offsite power.” A nuclear reactor and its backup system are built to manage this kind of an accident by using the backup power system to maintain the operations of the coolant pumps. More so, because the plant went off, it could not generate any electricity. For a period of one hour, the several installed emergency diesel power generators went on and provided the required electricity. Nonetheless, when the tsunami (a rare and larger one) happened, it caused floods to the diesel generators and made them fail (TEPCO press release (2011). A fundamental aspect of all nuclear power plant structure is “defense in depth.” This aspect results in engineers designing nuclear plants that can resist harsh disasters, even in the case of various systems failing. A big tsunami that damages all diesel generators at the same time is also anticipated. however, the tsunami that happened that day was not expected at all.
