Tornado missile simulation and design methodology. Volume 1: Simulation methodology, design applications and TORMIS computer code
Abstract
A probabilistic methodology was developed to predict the probabilities of tornado propelled missiles impacting and damaging nuclear power plant structures. Mathematical models of each event in the tornado missile hazard were developed and sequenced to form an integrated, time history simulation methodology. The models are data based where feasible. The data include documented records of tornado occurrence, field observations of missile transport, results of wind tunnel experiments, and missile impact tests. Probabilistic Monte Carlo techniques are used to estimate the risk probabilities. The methodology was encoded in the TORMIS computer code to facilitate numerical analysis and plant specific tornado missile probability assessments. Sensitivity analyses were performed on both the individual models and the integrated methodology, and risk was assessed for a hypothetical nuclear power plant design case study.
