*YUZURU EGUCHI¹, TAKAHIRO MURAKAMI¹, KOSUKE NAMBA¹, YASUO HATTORI¹ (1. Central Research Institute of Electric Power Industry)

Keywords:tornado, tornado-borne missle, annual strike probability, computer code, applicability

Using the probabilistic tornado-borne missile analysis code, TONBOS-pro, and the annual strike probability evaluation code, TOMAXI-pro, we conducted a realistic analysis for equipment and structures of a postulated nuclear power plant to evaluate the applicability of the codes.
