Developing Procedure for Nuclear Regulatory Vulnerability Assessment of Nuclear Power Plants

First attempts of developing the procedure and adopting the methodology for nuclear regulatory vulnerability assessment of nuclear power plants are presented. The development of the philosophy and computer tools could be new and important insight for management of nuclear operators and nuclear regulatory bodies who face difficult questions about how to assess the vulnerability of nuclear power plants and other nuclear facilities on external and internal threats. In the situation where different and hidden threat sources throughout the world are dispersed, the assessments of security and safe operation of nuclear power plants are very important. Most risk assessments of nuclear power plants emphasize probability more than consequences. In addition, the probabilities omit terrorists. As of 09/11/2001, the emphasis has changed and this paper tries to show how to do this. Probabilities are enhanced by showing they are dynamic, interactive, and include countermeasures. Consequences are also enhanced by their dynamic nature dividing them on short, intermediate and long term effects. Risk is enhanced by creatively distinguishing between perceived and estimated.Copyright © 2004 by ASME
