This report is a brief summary of risk science, which provides a good tool to understand quantitatively the potential for various kinds of hazards in our present environment from modern technologies. Risk is defined by two characteristics, that is, the degree of the effect of the hazard, and the uncertainties due to essentially stochastic effect and insufficient knowledge. A risk assessment technique is generally called PRA (Probabilistic Risk Assessment), when the probability is employed to calculate the initiating frequency of the stochastic event. The PRA is almost always sucessfully applied to the design of nuclear power plants to increase the performance of safety facilities. In addition, the PRA is considered to be a useful method to obtain an excellent insight into the risk perception and the risk acceptance for unclear power plants by the public in spite of the uncertainties mentioned above.
