Nuclear Accidents
World power needs are doubling every 20 years. As of today, Nuclear power output is about 14 % of total power needs of the world. The power business is therefore hard-pressed to enhance output and they do it by way of building up new power generation plants throughout the world. Approved 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 regularly related with the use of fossil materials, hazards are many due to potential exposure of mankind to radiation. Hence a indispensable opposition is built up internationally on the basis of risk complex due to accidents and problems related with nuclear waste management.

Apart from three major accidents together with the latest one in Fukushima Japan, history of nuclear power is more or less event free. This is due to spoton implementation of norms for nuclear protection 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 protection 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 effect of Tsunami and Sendai earthquake. Reports are being received about nuclear meltdown and explosions spreading radiation which may be carried on to separate parts of world creating catastrophe. For damage control large evacuation procedures and distribution of potassium iodide tablets are going on. But how much productive these measures are, only time can tell.
Nuclear protection standards are very rigid and nuclear reactors are built with emphasis given on provisions for protection while earthquake or other natural calamities. But there are determined elements which are beyond the power and control of human beings. The modern example is one among them. 9/11 strike by terrorists has been someone else eye opener for all concerned to think potential threats from terrorists on power generation plants.
The modern emergency in Japan followed by tsunami is of course 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 potential to meet the growing power needs compromising on protection aspects. The latest trend on the basis of opinions from expert is changing and there is every likelihood that the policy 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 determined a status sticker even by small nations. The trend may now change and citizen will start thinking to give more point to improving techniques to harness wind energy, solar energy, hydro-electric etc. Which are eco-friendly and unobjectionable to the mankind. And surely, scientists and technologists should try to make it economically viable to compete with the gift nuclear regime.
