Title: Analysis of HDR blowdown experiment for fluid-structure interactions

Abstract

The HDR experimental facility, comprised of a full-scale pressure vessel, core barrel, and piping systems is described. In the blowdown experiment, V31.1, the fluid-structure interaction of the core barrel and downcomer water is significant. This experiment is analyzed to assess the MULTIFLEX code. The HDR downcomer annulus is modeled by the one-dimensional network that is equivalent to two-dimensional fluid-structure interactions. The core barrel is modeled by the projector method for combined beam and shell models. The vessel motion is taken into account by means of the relative modal analysis proposed in this paper. Computed time histories of pressure, pressure differentials, and barrel wall displacements are compared with experimental data. Agreement between experiment and post-test computation is found. 11 refs.
