ICONE14-89378 EXPERIMENTAL STUDY ON STRUCTUAL INTEGRITY OF A CORE SHROUD SUPPORT WITH A CRACK UNDER SEISMIC LOAD

ABSTRACT This study was performed to experimentally confirm the conservatism of the integrity assessment procedure for a cracked core shroud support of the boiling water reactor (BWR) under seismic load. From the comparison of the experimental and analytical results, it is shown that finite element method (FEM) is accurate and collapse load estimated by twice-elastic slope method is conservative
