A Comparative Analysis of the Impact of the IAEA Cooperation Instruments in the Field of Nuclear Safety to Deal with the Fukushima Daiichi Accident vis-a-vis the Chernobyl Accident

On 26 April 1986, an explosion at Unit 4 at the Chernobyl nuclear power plant released a very large amount of radioactive material into the atmosphere. According to the conclusions raised at the "International Forum on Chernobyl´s Nuclear Safety Aspects" held in Vienna from 1 to 3 April 1996, two important causes of the accident were that: "there were significant deficiencies in the design of the reactor – in particular of its shutdown system – and operating procedures were severely violated at the time of the accident" and "there was a lack of safety culture in the organizations responsible for operation and for control: important safety weaknesses had been recognized long before the accident occurred but were not remedied." Only thanks to the discovery of an increase in environmental radioactivity in Nordic countries the international community was informed about the accident. On 11 March 2011, as one of the consequences of the tsunami waves generated by the Great East Japan Earthquake off the Pacific coast of Japan, the Fukushima Daiichi nuclear power plant accident took place. In his statement to the "International Conference on Chernobyl: Twenty-Five Years On - Safety for the Future" the International Atomic Energy Agency Director General, Mr. Yukiya Amano, pointed out "Chernobyl led to a great step forward in international cooperation in the field of nuclear safety. We now have four safety conventions, two Codes of Conduct, fundamental safety principles and a body of globally recognised IAEA Safety Standards." [ ] "An international coordinated response system, with the IAEA's Incident and Emergency Centre at its heart, is now in place." [ ] "We also have an IAEA peer review system, based on the Agency's Safety Standards." But Mr. Amano also recognized that "despite the great progress made in the last 25 years, more needs to be done to ensure that a ''Safety First'' approach becomes fully entrenched among nuclear power plant operators, governments and regulators." This work intends to make a comparative analysis of the impact of the IAEA cooperation instruments in the field of nuclear safety to deal with the Fukushima Daiichi accident vis-a-vis the Chernobyl accident.
