High Wind Missile Strike Probability Tornado Tumbling Typhoon
Injection of objects into high wind and flight in the air are numerically simulated using a random orientation model in order to mimic the tumbling of the objects. The computed random trajectories are used to evaluate annual strike probability on a target by considering the annual exceedance probability of the wind speed at the points where the objects are initially placed. Assuming that the direction of tornado translational path or the direction of straight wind is stochastically random, such numerical sc...

Hazard model Nuclear power plant Path length Tornado Tornado intensity
Abstract: Most of Japanese tornados have been reported near the coast line, where all of Japanese nuclear power plants are located. It is necessary for Japanese electric power companies to assess tornado risks on the plants according to a new regulation in 2013. The new regulatory guide exemplifies a tornado hazard model, which cannot consider the variation of tornado intensity along the path length and consequently produces conservative risk estimates. The guide also recommends the long narrow strip a...

Building Missile Strike Probability Structure Tornado
A computer code, TOMAXI, was developed to evaluate annual strike probability of a tornado-borne missile for a vertical or horizontal plate of unit area placed in an arbitrary position in our previous study, assuming that the direction of tornado translational path is stochastically random. In the present study, the authors have extended the function of TOMAXI to compute annual strike probability of a tornado-borne missile for a building or a structure of arbitrary shape placed in an arbitrary position. As a...

Design speed Fujita model Liftoff Numerical simulation Standard Tornado missile
Abstract: Large variation was found among the design values of tornado missile speed shown in current stan dards and guides in Japan and U.S. It was also found that the design missile speed indicated in the Guide issued by the Nuclear Regulation Authority of Japan is the most restrictive among them. The primary reason is due to the evaluation method where all the objects are unconditionally assumed to be placed in air as gh as 40 m, even if the object should be on the ground. In order to solve this problem...
