The objective of this study is the development of improved methods and criteria for estimating blast casualties and for handling nuclear fire effects in order to determine means for improving survivability and injury avoidance for shelter occupants. The urban fire analysis model, FIREFLY, was developed to provide an automated method for assesing the potential damage to shelter buildings from fires which occur as a result of ignition from the thermal pulse of a nuclear weapon or fire spread from nearby buildings. Two promising approaches for classification of urban environments with regard to potential fire susceptibility were developed. Upon the basis of blast vulnerability analyses of structures including interior floors, walls and partitions, a set of blast fatality functions was produced which may be used to determine the survivability of personnel in shelters in various locations within three principal types of structures. Trial applications of improved methods and criteria served as a pilot sensitivity analysis for future shelter systems vulnerability analyses. Author
