SIMFIC: A Simple, Efficient Fallout Prediction Model

摘要

Details are given of the basis and mathematical structure of a fast, simple code, SIMFIC, for prediction of local fallout from surface and above surface nuclear weapon explosions. Verification results are presented for five tests shot cases for which observed fallout patterns are available and which cover a yield range of 0.5 to 3380 KT. Prediction accuracy is as high as that obtained from the DELFIC code for these cases. Computing speed is on par with a code currently used for large-scale damage assessment studies. Other computing requirements are discussed briefly. (Author)
