Public always perceive higher levels of risk perception of a nuclear power plant，this article tried to explore the impacts of risk information on public risk perception of nuclear facilities. In this article，construction of Haiyang nuclear power plant was set as the research situation，the questionnaire investigation was adopted. This article tried to explore the impacts of risk information on public risk perception of nuclear facilities and build a hypothetical model on the basis of the information flow of Protective Action Decision Model （PADM） to evaluate risk perception. The results showed that the formation of public risk perception is due to the information they received from the traditional information channels and the network information channels，along with their knowledge about nuclear energy and nuclear accidents. Nuclear power knowledge has negative effects on risk perception，while nuclear accident knowledge has positive effects on risk perception. Benefit perception also had a significant effect on risk perception with an inverted u-shaped relationship between them.
