Tornado missile risk analysis: probability modeling, simulation methodology, and case studies. Final report. [TORMIS code]
Mathematical models of the contributing events to the tornado missile hazard at nuclear power plants have been developed in which the major sources of uncertainty have been considered in a probabilistic framework. These models have been structured into a sequential event formalism which permits the treatment of both single and multiple missile generation events. A simulation computer code utilizing these models has been developed to obtain estimates of tornado missile event likelihoods. Two case studies have been analyzed: a single unit plant using the current NRC set of missiles and a two unit arrangement using an expanded missile set. Preliminary results suggest that the likelihood of missile strike and that of subsequent plant damage may be acceptably small.
