Nuclear Power: Is It Blessing Or Disaster in East Asia?

Nuclear energy is economically feasible. Therefore, nuclear power plants produce about 16 % of the world’s electricity nowadays. Calder Hall in the United Kingdom is the world’s first commercial nuclear power station in 1956 (1). In the United States, Shippingport was first operated since 1957. However, the accident like Three Mile Island and Chernobyl disaster had awakened people to the dangers of nuclear energy; especially Fukushima disaster caused the pollution of radiation recently (2). There are 435 operating reactors all over the world in 2012 (3). Sixty-two reactors are under construction and 160 reactors are in the plan. East Asia has a lot of operating reactors besides planned atomic plant (Table 1). Planned reactors in East Asia have a proportion over 40 % of the whole world. Degree of nuclear accumulation is higher due to construction mostly on the coastal area. Germen government decided to close operating nuclear power plant and give more weight to renewable energy after Fukushima disaster. If East Asian countries have inevitable reasons to main-tain nuclear energy for electricity, economics has to be balanced against environmental and safe concerns
