Abstract:

This report analyzes the use of optical flash sources in testing of Nuclear Burst Detection System NBDS devices. The primary case studied is that of the use of thermochemical reactions to simulate nuclear fireballs. The report reviews the NBDS requirements and weapon output, contrasting the outputs of a variety of simulation sources. Of the sources studied, the thermochemical reactions require detailed modeling, and this is reported. Two general types of models are reported. The first is based on very simple thermal behavior but predicts the growth of fireballs in agreement with previous thermochemical tests of a wide variety of types and sizes. The second type of model considers each step in detail in the fireball development. This is useful for tailoring of the fireball output. Detailed data comparison with a number of thermochemical reaction tests and recommendations conclude the report. Author
