[en] A brief review of the turbine missile problem at nuclear power generating facilities is presented. It includes information on present US requirements, the probability of missile generation, the shape, size, and velocity of potential missiles, as well as common barrier designs and the typical damage modes associated with each. Data from recent turbine missile impact tests conducted on both metal and concrete barriers is compiled from the US and around the world. The validity of scale modeling as a data acquisition method is discussed. Existing empirical formulas for each mode of barrier damage are evaluated using the turbine missile data sets. In addition, the effects of the pertinent parameters for each case are studied
