At the Committe on the Safety of Nuclear Installations (CSNI) meeting of June 2002, a proposal for an International Standard Problem on containment integrity (ISP 48) based on the NRC/NUPEC/Sandia test was approved. Objectives are to extend the understanding of capacities of actual containment structures based on results of the PCCV model test and other previous reserach. The ISP is sponsored by the USNRC, and results were made available thanks to NUPEC and to the USNRC. Sandia National Laboratory was contracted to manage the technical aspects of the ISP.
This report presents the pretest analysis results of the calculation of the limit state test (LST), i.e. static pressure loading, provided by the ISP 48 particpants.
