"It was the belief in Japan at that time that this facility was robust... and even that it was not a good idea to conduct upgrades or changes to the facility because this could demonstrate in terms of public communication some weaknesses," Juan Carlos Lentijo, head of nuclear safety at the IAEA, told AFP. To mitigate further disasters, a body called The World Association of Nuclear Operators (WANO) was set up that is geared towards safe and reliable operation of nuclear power plants by conducting independent peer reviews for every new nuclear power plant operating … Compared with other energy sources, nuclear power is relatively safe and relatively clean, and will be part of energy production for the foreseeable future.
