The impact of nuclear accidents has been a topic of debate since the first nuclear reactors were constructed in 1954 and has been a key factor in public concern about nuclear facilities. Examples include lethal effects to individuals, large radioactivity release to the environment, reactor core melt.' The prime example of a 'major nuclear accident' is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima Daiichi nuclear disaster in 2011. Ī nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as 'an event that has led to significant consequences to people, the environment or the facility. Safety-critical systems were found to be undamaged by the earthquake. The Kashiwazaki-Kariwa Nuclear Power Plant, a Japanese nuclear plant with seven units, the largest single nuclear power station in the world, was completely shut down for 21 months following an earthquake in 2007.
