However, this rosy picture was deeply broken by the Japanese nuclear incident in March 2011. People can not help but called a big question mark in the heart: nuclear power: blessing or disaster?
As we all know, nuclear energy is a kind of safe and clean energy, On the one hand, as a future substitute for fossil fuels, its greenhouse gas emissions almost to zero, and since the nuclear fuel is expended only as much as one-third coal, moreover , all fission energy released by 1 kilograms of uranium fission, roughly equivalent to 2500 tons of coal or 2,000 tons of oil combustion energy released, it is believed that nuclear power exactly more economical and durable. On the other hand, Compared with other new energy sources such as wind ` hydro `solar `bio-energy, nuclear power also could not be neglected in advantage. Not only can it grows extremely fast, but also be used on a large scale. Especially with the energy supply and demand contradiction hardly reconciled and the environmental protection pressure over-burdened. Obviously , The use of nuclear energy has become an important guarantee for the energy strategy to achieve sustainable development and the construction of human society in future.
However, in March 2011, Fukushima Japan nuclear leak has sounded the alarm for human using nuclear power. Recalling the process of nuclear energy of developed by human, nuclear crisis, or continue to unfold. The Wim Wenders Kyle nuclear power plant incident in 1957 has been the UK's "political minefield In 1979, the Three Mile Island nuclear leaks into the anti-nuclear movement "assembly", and In 1986, the Ukraine's Chernobyl nuclear accident led to a major disaster, making people "on the nuclear pale." According to data from the world nuclear association, there are 201 nuclear power plants in the whole world, besides, 443 nuclear power plant is running, not including plants under construction or design. Some people even regard twenty-first Century as "the nuclear century “. This high-density aggregation of nuclear power plants critically disturbs people’s mind: whether the Earth is becoming a time bomb, exploding the future of mankind in any time.
But please note, the history of the nuclear leakage tragedy mostly caused by design defects and deliberately concealment of potential safety hazard, that is to say, the cardinal reason is human factor. With the rapid development of science and technology, nuclear power plant safety performance has greatly improved, what aspect we should pay more attention to is the loopholes in management.
I have always believed that human have two kinds of rational, one is technology, another is reflection. The Fukushima nuclear explosion may be nothing less than an improvement opportunity, because the concern on technology and capacity of their own precisely represent human’s prudent and wise. Nuclear power plant is an achievement of human technological development and humanity's achievements, but more rational, is that of rational reflection.
Former U.S. President Jimmy Carter has said: "nuclear energy should be as a last alternative energy", in a time of frustration, we should not stop the pace of progress, nuclear power is a benefit or destruction, rests in you, I, of all mankind hands, I do believe that the world in my mind will eventually become a reality!
