Title: Preliminary characterization of the pressure suppression experiment load response and source analysis: air test series. [BWR]

Abstract

Data from air tests conducted on the 1/5-Scale Model Mark I Pressure Suppression Facility at Lawrence Livermore Laboratory were analyzed for the purpose of determining the various sources of load signature characteristics. It was determined that hydrodynamic vertical loading function embodies effects from: (a) momentum flux associated with flow from the downcomers; (b) momentum rate associated with bulk pool motion; and (c) unbalanced internal pressure forces related to phenomena associated with vent clearing. The integral form of the linear momentum equation is used to derive qualitative and quantitative insight into the mechanics of the hydrodynamic loading function. Amplitude spectra derived from Fourier transformations show that the 25 Hz (approximate) structural mode is the only frequency which appears consistently in all wave forms which were spectrum analyzed.
