What are some of the issues of nuclear power plants?

Nuclear power amounts for a somewhat large portion of our the energy that we use. However, nuclear spills can be devastating. When a nuclear power plant leaks, radioactive material is released into the environment. This material is extremely harmful to humans and can cause many health problems and cancer. Radiation is spread through the air. It can take many years for the harmful material in the environment to go away. One of the most well-known nuclear accidents was the disaster at Chernobyl. Also, the Fukushima Daiichi nuclear power plant in Japan recently had a spill.
