Disadvantages of Nuclear Energy. 1. Radioactive Waste: The waste produced by nuclear reactors needs to be disposed off at a safe place since they are extremely hazardous and can leak radiations if not stored properly. Such kind of waste emits radiations from tens to hundreds of years.
This potentially results in cheaper energy, though, because of the very high (and necessary) safety standards used in the nuclear industry, the cost of building and operating fission nuclear reactors is increasing significantly over the years, resulting in nuclear energy being now usually more expensive than electricity from coal power plants.
