On March 11, 2011 and earthquake of grade 9 on the Richter scale sacudio (the larger on the 1400 years or records history ) the Pacific coast of Tohoku in which the Fukushima nuclear power complex is located. The initial disaster did not represented any significant risk even the power cut that isolate the complex from the electric grid the generators in place kept the cooling system of the generators running and the 3 operating reactors active at that moment initiated an automatic shutdown to protect the cores, what nobody at this point was expecting was a tsunami with a wave higher than 15 meters that forty-one minutes later hit the seawall that originally was designed to withstand waves up to 6 meters. This caused significant flooding on all the installations and malfunction on the diesel generators, replacement batteries in place powered the cooling system, but couldn’t prevent those from overheating oxidising their protective cladding and melting their radioactive cores, producing significant amount of hydrogen in reactors 1,2 and 3 which eventually exploded damaging the containing vessels. Reactors 1, 3 and 4 had significant leaking given the structural damage, and contaminated water was released to the environment. Overall by the end of the first crisis, three of the six reactors suffered a partial meltdown with the consequent release of radioactivity that contaminated the atmosphere and water from the reactors that reached the ocean.
The situation raised many ethical issues given the nature of the incident and the implications as well as the behaviour that Tokyo Electric Power Company, Incorporated (TEPCO) the company in charge of the installations handled the incident who during the whole crisis failure to communicate properly and promptly about the progress of the situation.

II. Ethical theories and principles
There are multiple ethical issues that must be taking into account given the risk and implications nuclear power operation and nuclear waste implies , the following document will focus on the most significant ethical theories that apply to the accident of the Fukushima power complex.
- Protection of human health – The release of radiation on the incident exposed thousands of people to radiations, no radiation death seem to be cause by the radiations but about 1600 people died  related to the evacuation conditions.
- Protection of the environment – By November 2011 the Science Ministry reported that long-lived radioactive Caesium had contaminated 30,000 sq. km of the land surface of Japan of which 700 sq. km were declare to have too radioactive for human habitation . The water leaked is not less significant, the complex had been having problems to contain contaminated...
