EQUILIBRIUM P-V-T RELATIONS FOR EXPANDING LIQUID-VAPOR SYSTEMS IN A CONTAINMENT SHELL

TL;DRAbstract

From a time-independent standpoint, formulas are developed for determining a containment shell for a reactor plant should an unforeseen malfunction, where a compressed liquid, liquid-vapor, or vapor system is liberated and expands, occur. From the thermal equilibrium states, the pressure build-up inside a containment shell of known free volume is obtained, or for a specified containment shell pressure the required free volume is evolved. For the pressure build-up inside a containment shell due to ancident on a time- dependent basis, formulas are evolved from an open-system aspect. A table and graphs fur various initial states expanding into a containment shell have been prepared, where timeis not considered. Examples illustrating the usage of the developed time-independent equations are given. (auth)
