Nuclear Accidents
World energy needs are doubling every 20 years. As of today, Nuclear power production is about 14 % of total power needs of the world. The power business is therefore hard-pressed to improve production and they do it by way of construction up new power generation plants throughout the world. Accepted methods of using wind power generators, diesel power generators and water powered generators are found to be insufficient to meet the growing demands of the world; and hence the shift towards power generation plants using nuclear power reactors. Though latter has been found to be economically viable to contribute sustainable energy, reducing carbon emissions ordinarily connected with the use of fossil materials, hazards are many due to inherent exposure of mankind to radiation. Hence a primary opposition is built up internationally on the basis of risk involved due to accidents and problems connected with nuclear waste management.

Apart from three major accidents including the newest one in Fukushima Japan, history of nuclear energy is more or less event free. This is due to spoton implementation of norms for nuclear security and constant monitoring by international agencies. Nuclear power generation techniques also improved with the amelioration of science and technology. More emphasis is given to the nuclear security and nuclear waste management. Nuclear community has learned lessons from Three Mile Island emergency in Pennsylvania in 1979 and Chernobyl, Ukraine in 1986. Since then, all the 440 reactors throughout world have been functioning free of major accidents till this Fukushima emergency occurred as a result of Tsunami and Sendai earthquake. Reports are being received about nuclear meltdown and explosions spreading radiation which may be carried on to distinct parts of world creating catastrophe. For damage control large evacuation procedures and distribution of potassium iodide tablets are going on. But how much efficient these measures are, only time can tell.
Nuclear security standards are very rigid and nuclear reactors are built with emphasis given on provisions for security during earthquake or other natural calamities. But there are confident elements which are beyond the power and control of human beings. The up-to-date example is one among them. 9/11 strike by terrorists has been someone else eye opener for all involved to reconsider inherent threats from terrorists on power generation plants.
The up-to-date emergency in Japan followed by tsunami is absolutely a setback to the proponents of nuclear power generation and it may lead to an introspection among world leaders. They are sure to understand it is dangerous to go ahead with nuclear programs with unabated speed and to build up as many nuclear power plants as inherent to meet the growing energy needs compromising on security aspects. The newest trend on the basis of opinions from master is changing and there is every likelihood that the course being followed may undertake a major change. Due to Economic compulsions internationally, it is doubted that there exist some sort of complacency even today and more and more nations are attracted towards nuclear energy. Getting an entry into the elite nuclear club is being thought about a status fastener even by small nations. The trend may now change and population will start thinking to give more point to enhancing techniques to harness wind energy, solar energy, hydro-electric etc. Which are eco-friendly and inoffensive to the mankind. And surely, scientists and technologists should try to make it economically viable to compete with the gift nuclear regime.
