Advantages and Disadvantages of a nuclear plant


Nuclear Plants
Advantages of nuclear plant
·       Bring jobs and prosperity to a town or country
·       Provides the world with most of its electricity 
·       Good for the country’s economy 
·       More efficient than ever before
o    New technology has made them more reliable and safer
§  Evidenced by more and more nations (such as China) building nuclear power plants.
·       Reduce greenhouse gas emissions
·       Although the initial cost of building is high, the running costs are low
·       Reduces dependence on foreign oils and natural gas (like bio fuels).
·       Can be safely stored underground 
·       Release a million times more energy, as compared to hydro or wind energy.

Disadvantages of nuclear plant
·       Radioactive waste
o   Produce a lot of waste material
o   Waste material is extremely hazardous and difficult to dispose off safely
§  Keep on site or is buried underground in huge concrete pits
§  Must be carefully looked after for many thousands of years.
·       High risks associated with accidents
o   Small radiation leaks can cause devastating effects on the surrounding environment and people (Japan)
o   A cataclysmic accident can cause widespread radiation poisoning across many countries
§  Chernobyl Nuclear disaster
·       Terrorist Targets 
o   Because of the wide spread damage a reactor breach could cause
§  Terrorist Targets
§  Some nuclear reactions also produce plutonium in large quantities
·       Used in nuclear weaponry



·       Not renewable
o   Uranium is a scarce metal
o   Will one day run out
§  All nuclear power plants obsolete




·       Time and Money
o   Long time
§  Plan and build a nuclear power plant that is safe and effective
o   Lot of money spent
§  Ensure it is safe
§  Unsafe nuclear plants more prone to accidents
