At the Committee on the Safety of Nuclear Installations (CSNI) meeting in June 2002, the proposal for an International Standard Problem on containment integrity (ISP 48) based on the NRC/NUPEC/Sandia test was approved. Objectives were to extend the understanding of capacities of actual containment structures based on results of the recent PCCV model test and other previous research. The ISP was sponsored by the USNRC, and results had been 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 analysis results of the calculation of the limit state test (LST), i.e. static pressure loading, and of the calculations of response to both thermal and mechanical loadings, provided by the ISP48 participants.
Volumes 2 and 3 contain the individual participant reports for both Phases 2 and 3.
