Abstract:
Computational and experimental methods are developed to model (using explosion and impact) shock-wave processes in the walls of the explosion chamber of pulsed nuclear power plants exposed to powerful X-ray radiation. A comparison shows that experimental and calculated parameters of shock waves produced by explosive and shock loading of various materials are in good agreement with each other. The methods developed were used to study the behavior of a Li$_{17}$Pb$_{83}$ cooling liquid film on the explosion-chamber wall when the recoil momentum caused by vaporization is the major loading factor. The possibilities of reducing the explosive loads on the walls are considered.
