There exists a so-called "experts-lay people" gap in discourses about nuclear safety, because experts and lay people have a different definition of 'safety'. However, it is getting increasingly important for nuclear practitioners to understand the lay people's subjective perception of nuclear safety. We developed the indices of effective safety in nuclear domain of Korea. The index of effective safety indicators (IOES) are based on data of the public survey of local inhabitants. The research results are as follows: Extraction of four sub-factors for effective safety indicators; Communication, Trust, Plant emergency response capability, and Personal emergency coping skills. The IOES was 38.22, which was extremely low. The IOES is a sort of an 'absolute' index and hard to imagine that people feel 'absolutely' safe regarding nuclear power plants. As a more realistic index, we devised a relative index of effective safety (RIOES), which is basically a proportion of residents' IOES to that of the employees of nuclear power plants. RIOES was 56.77, meaning that the level of effective safety of residents was only 56.77 % of that of the employees. The proposed indices can be utilized as an useful communication tool between the local inhabitants and nuclear practitioners.
