Simulation Of The Effect Of X-rays On The Cellular Structure Of The Chamber Walls Of A Nuclear Power Facility

摘要

Computational and experimental methods are developed for simulating, by means of an explosion and shock, the wave processes occurring in the walls of the explosion chamber of pulsed nuclear power facilities under intense x-ray irradiation. The experimental measured and computed parameters of shock waves accompanying explosive and shock loading of different materials were in satisfactory agreement with one another. The methods developed are used to investigate the behavior of a liquid heat-protective film of Li_(17)Pb_(83) on the wall of the explosion chamber when the recoil pulse produced by evaporation is the main load factor. The possibilities of decreasing the explosive loads by changing the thickness of the lead shell of the charge and by including cellular structures and porous materials in the chamber walls are examined.
