Abstract [en]

Nuclear power risks for the public were recognized as an important issue and are subject of several probabilistic risk assessments (PRAs) starting with the WASH-1400 risk study performed in early 1970s[1]. Nuclear safety goals were also formulated based on these studies and/or independently. Both the goals and the formulation of the risks considered the effects of radioactivity releases on the health of a population affected in the vicinity of a nuclear power plant undergoing an accident. WASH-1400 also considered the land contamination that a radioactive release may inflict. The Fukushima accident has highlighted that the principal consequences of a nuclear severe accident may not be the immediate fatalities and injuries and the latent (cancer) health effects, but the societal upheaval and the economic damage that could be caused by a major release of radioactivity to the environment. Such consequences of a severe nuclear accident bring a quite different focus to the risk profile of large-scale deployment of nuclear power in the world. This is addressed in this paper, along with the ancillary issues; design basis, residual risk, cost benefit and back-fit rules, GEN II plants, GEN III + plants, operator performance during severe accidents, fear of radioactivity, and finally public confidence in nuclear power.
