'''Tornado Missile Strike Calculator (TMSC)'''<br />
<br />
The Tornado Missile Strike Calculator is an EPRI-developed tool that computes the conditional probability of wind-borne missile impact on structures at nuclear power plant sites. TMSC uses Monte Carlo simulation to model missile injection, flight trajectories, and target intersection for both tornado and straight-wind events. The primary output — conditional multiple missile hit probability — feeds directly into the plant response model of a high-wind probabilistic risk assessment.<br />
