Over the last several decades, scientists have addressed the problem of nonrenewable natural resources such as fossil fuels. Humans are using fossil fuels at a rapid rate and scientists believe that one day we will run out of them. To solve this problem, research has been conducted on alternative energy sources. One alternative energy source is nuclear energy. Although nuclear energy is a good solution to this problem, there are concerns.
