Fukushima nuclear accident has died away from us now, reactors are more stable. We look back at Chernobyl 25 anniversary, bound to compare the two. Is important in facing the global energy crisis, we want to have a vision. As more scholars in the study of when human growth in demand for clean energy, nuclear energy is on the brink of a new Renaissance. As mentioned in the Obama overall state of the Union, that nuclear power play an important role in resolving the existing energy. United States has a good record of safe use of nuclear energy, in fact, throughout the history of commercial nuclear power is not a public damage or death because of nuclear energy.
Today, Ukraine qienuobeili the 25 anniversary of the accident, it is necessary to explain to the public what happened to Chernobyl, how it had occurred and why it won’t happen again. Also, from Fukushima incident drew additional lessons are equally important. Looking back, looking ahead, better design, strict supervision of existing nuclear power stations, a full range of security measures was second by Chernobyl impossible.
The Chernobyl reactor, 4th, and a series of events eventually led to the most serious accident in the history of nuclear energy. The cause of the disaster include mistakes in design and operation of the reactors unsafe, it destroyed the reactor, in a few seconds to release a large amount of heat and flame and steam.
Chernobyl reactor design is very unique, high enrichment of uranium fuel it used graphite as a moderator. Postmortem analysis confirmed that only this type of catastrophic accident. The reactors provide power to the Soviet Union also provided military weapons-grade plutonium. Complex it controls, and the need to constantly adjust to maintain stability. And management officials at that time was an electrical engineer, nuclear power is not professional. Sequence of events leading to accidents is the main generator of building materials from the reactor building engineering testing began. Because the test had been delayed, and managers hoping to catch up with the progress, resulting in a series of events eventually caused the disaster.
Fukushima nuclear power plants, from the situation we now know, accidents are not due to a design flaw or human error, but because humans are too serious for exceeding our expectation of a natural disaster. To be precise, is not because of the tsunami earthquake led to a loss of power caused a reactor core cooling crisis. In fact, the reactor design and construction requirements on the line – automatically shut down after the earthquake.
It is also important, that is, none of the deaths occurred in the accident, all security measures are performed in accordance with planned in an orderly manner, all of which are public, and avoid the occurrence of panic. Furthermore, accident rate to account for so in accordance with the International Atomic Energy Agency, Fukushima nuclear accident like Chernobyl to level 7, but this is the sum 4 reactor accident hazards, not a heap. More important is that the Fukushima nuclear accident leaks of radiation is the Chernobyl one-tenth.
United States of existing nuclear power stations ensure that will not happen in the design of the Chernobyl accident, and after an earthquake testing, similar Fukushima nuclear accident is unlikely to happen. More important is because the nuclear scientists, engineers and even nuclear energy industry as a whole attaches great importance to safety culture, future nuclear power plants will add additional security measures, safety studies and accident prevention. This safety culture after the 911 all nuclear power plants for reasons of insufficient ability to analyze and improve the anti-terrorist attacks.
Nuclear scientists in the world have come together to create a professional organization, committed to making nuclear power stations reached the highest level of security in all aspects of the production process, there is no doubt that safety culture of nuclear safety regulations, and reached consensus on a global scale. Through the World Association of nuclear operators (WANO), all the nuclear power plant safety improvements and good practices are continuously monitoring, rich, and in the world is shared by all the nuclear power plant. These measures is to provide safe, reliable electricity in nuclear power station of fundamental guarantees.
Today, the 16% of the world’s power comes from nuclear power, China, India, more than 30 countries committed to dozens of new reactor, which embodies the world kernel industrial revival. For us, we not only want to consider our energy needs, we would leave the next generation of Earth is more. Do we want to continue using fossil energy and let our next generations suffer the consequences of global warming do? Alternatively, we can create an enjoy the clean and efficient energy for a bright future of nuclear energy.
The Chernobyl accident killed 50 people. Today, after disaster 25, in memory of the deceased, we also know that world within the nuclear industry has changed, we can ensure the safe use of nuclear energy worldwide. We would also like to know, no deaths in the Fukushima nuclear accident. We will also continue to study the Fukushima nuclear accidents, to further improve the security and reliability of nuclear power plants. We assure that in Chernobyl and Fukushima nuclear stability and pay tribute to the hard-working people, we know that nuclear energy will play an important role in future energy.
