概要
An evaluation of failure probability for facilities in a real plant subjected to tornado missiles was introduced based on simple calculation. Impact speeds of the tornado missiles to the plant facility were calculated, assuming several initial locations for them and Rankine's model or Fujita's model as a tornado vortex model. Failure probability of each facility subjected to the tornado missiles was quantitatively evaluated, taking account of probabilities of tornado strike to the plant, number of missiles and so on. The results show that we can reduce the failure probability of the facilities by appropriate management of prospective missiles especially at the building roof.
