Abstract

Abstract

An experimental method in the confinement vessel for silver aerosol source-term investigation of metal under high explosive detonation was designed to simulate the plutonium aerosol source-term of nuclear devices under the circumstance of high explosive detonation. Seven silver source-term experiments under variable explosive pressure were conducted in the aerosol facility and the size distribution characteristics of the silver aerosol with an aerodynamic diameter less than 10 μm were examined and compared with the data from the field test. The results show that the silver aerosol source-term under specific conditions has good agreement with the plutonium aerosol source-term obtained by the U. S. government under test conditions simulating an open-air detonation accident of nuclear device. The amount of the silver aerosolized in the experiment is determined by the peak value of high explosive pressure that acted on the silver plate and exhibited a quadratic polynomial. The silver aerosol with an aerodynamic diameter ranging from 0.7 to 3.3 μm account for the major part of the silver aerosol induced by high explosive detonation. When the peak value exceeds a certain critical value, the total amount of aerosol reaches the maximum. Settlement and combination of aerosol were observed in the comparative analysis of the size-mass distribution of the samples collected at different times after the explosion.
