Abstract: The study on nuclear energy development is summarized in the following four conclusions:the development of nuclear power can offset the electricity deficit of economic development;it is necessary to develop nuclear energy which is a kind of stable low-carbon energy considering CO₂ emission reduction;with a good foundation of industrial chain of steady progressing,nuclear development cannot be easily forsaken from sustainable development perspective;and the nuclear fuel is an important way of safeguarding energy security,promoting self-sufficiency of energy and replacing fossil energy import.Therefore it is very important to improve nuclear safety and the public acceptance to ensure that nuclear energy can be developed steadily.
