Nuclear energy represents only 15% of the electricity produced worldwide. Though in France, 80% of its electricity production is from nuclear energy and more than one-fourth of electricity in Europe comes from nuclear energy. Nuclear energy represents a very small percentage in many countries’ total electricity production, but this percentage is likely to go up in the coming years. Nuclear power is generated using Uranium, a mineral of which one of the isotopes, U- 234 is unstable. The nucleus breaks down resulting in the emission of heat and radiation followed by a chain reaction. This is called nuclear fission and this process liberates a large amount of energy, but the process also releases radiation which is very dangerous.
On 1 May 1989 the American Physical Society held a session on cold fusion in Baltimore, including many reports of experiments that failed to produce evidence of cold fusion. At the end of the session, eight of the nine leading speakers stated that they considered the initial Fleischmann and Pons claim dead, with the ninth, Johann Rafelski , abstaining.  Steven E. Koonin of Caltech called the Utah report a result of " the incompetence and delusion of Pons and Fleischmann, " which was met with a standing ovation.  Douglas R. O. Morrison , a physicist representing CERN , was the first to call the episode an example of pathological science .
