Abstract

Although nuclear accidents with large consequences are considered to have a very low probability, it is imperative to assess the consequences of severe accidents. Accidents are to be avoided, but to what price should an accident situation be prevented? One point of view is that the cost of prevention should be related to the cost of accident consequences. This paper presents a cost-benefit analysis, where the costs of accident consequences are included, along with all other costs of operating a nuclear reactor. The benefit of inspections is addressed in a computer intensive simulation model of the main coolant loops of a nuclear reactor. 1 Background Nuclear safety implies maintained cooling of the nuclear fuel and maintained structural integrity of the barriers. In a nuclear power plant there are several barriers for the nucle
