STUDIES OF REACTOR CONTAINMENT. Summary Report No. 2 for August 1, 1959 to January 31, 1960
Studies on the behavior of pressure waves in mirtures of water and its vapcr were completed. The approximations involved in a fluid dynamic model of non-linear solids in a zone of extremely high stress intensity were investigated. A pcssible fluid equation of state for the solid was derived which gives an analytical fit to shock compression data previously determined. Calculations were made of the shock pressure and wave front geometry of a I kt pcintsource explosion in water in contact with low, average, and high density concretes. A two-shock configuration resultirg from a pressure rise within the reactor vessel was determined. The interaction coefficients and boundary conditions governing a Mach configuration were investigated. Theoretical calculations of the dynamic compression properties of crushable solids by shock impingement experiments in a strong shock tube were made. Measurements of density and incident and reflected pressures for redwood, pine, balsa, celotex, foamglass, and styrofoam were made under conditions of shock compression. Modifications were made in the glass tube for controlled study of the explosive decompression of water. The effects of pressure magnitude and wave shapes associated with water hammer phenomena and pressure vessel diaphragm rupture characteristics were studied at 65 and 110 deg F. Apparatus and techniques were developed for the study of the behavior of porous materials when rapidly compressed. The displacement-time history of steel plates which were accelerated by means of explosives and retarded by porous materials, such as wood or felted fibers, was observed. A method of analysis for the deformation of cylindrical shells with rigid end closures under static load was developed. The method is applicable to cases of dynamic loading in which the inertia effects are negligible. (For preceding period see ARF
