The greenhouse gas emissions from nuclear fission power are much smaller than those associated with coal , oil and gas , and the routine health risks are much smaller than those associated with coal . However , there is a " catastrophic risk " potential if containment fails , which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the environment . This potential risk could wipe out the benefits . The most long-lived radioactive wastes , including spent nuclear fuel , must be contained and isolated from the environment for a long period of time . On the other side , spent nuclear fuel could be reused , yielding even more energy , and reducing the amount of waste to be contained . The public has been made sensitive to these risks and there has been considerable public opposition , so because of that it may impact our day to day life it splits the viral fever because of petrol and coal factorys The 1979 Three Mile Island accident and 1986 Chernobyl disaster , along with high construction costs , also compounded by delays resulting from a steady schedule of demonstrations , injunctions and political actions , caused by the anti-nuclear opposition , ended the rapid growth of global nuclear power capacity . A release of radioactive materials followed the 2011 Japanese tsunami which damaged the Fukushima I Nuclear Power Plant , resulting in hydrogen gas explosions and partial meltdowns classified as a Level 7 event . The large-scale release of radioactivity resulted in people being evacuated from a 20 km exclusion zone set up around the power plant , similar to the 30 km radius Chernobyl Exclusion Zone still in effect . But published works suggest that the radioactivity levels have lowered enough to now have only a limited impact on wildlife . In Japan , in July 2016 , Fukushima Prefecture announced that the number of evacuees following the Great East Japan earthquake events , had fallen below 90,000 , in part following the lifting of evacuation orders issued in some municipalities
