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.
Very large amounts of energy can be created with very small amounts of uranium through nuclear fission in a reactor. Nuclear power is a reliable energy source and it produces minute amounts of waste. Now looking at the cons of nuclear power we see the same small amount of waste with no fail safe way of managing it. Then because uranium is a non-renewable energy we could eventually run out, leaving many very expensive reactors useless. On to probably the biggest problem of nuclear energy is the worry of accidents.
