英文小作文：

Fission is a process that occurs in atoms and releases energy. It involves the splitting of an atom, which releases a large amount of energy that can be used for various purposes, such as generating electricity or creating explosives. Fission reactors are used to generate electricity and are considered to be a clean source of energy because they do not produce radioactive waste. However, there are also concerns about the safety of fission, especially when it comes to the handling of radioactive materials and the potential for accidents or terrorist attacks. Nevertheless, fission has played an important role in the development of nuclear power and continues to be an important part of the nuclear energy industry today.
