Design, fabrication, testing, and analyses of four 1:32-scale steel containment models

摘要

The fabrication, instrumentation, testing, and analyses of four 1: 32-scale containment models that are representative of hybrid and free standing steel containment buildings found in the commercial nuclear power industry is documented in this report. This phase of the containment testing and analysis program was conducted at Sandia National Laboratories for the US Nuclear Regulatory Commission from May 1981 to December 1984. The results from the testing provide data that was used to better understand the ultimate capacity of steel containment structures subjected to quasi-static pressure loadings and has provided structural data that can be further used to qualify and validate computer analysis programs and techniques. The baseline containment configuration was a cylindrical shell capped with a hemispherical dome. Two baseline models were tested. To this baseline model, circumferential ring stiffeners were added to the second configuration and three representations of large penetrations--an equipment hatch and two personnel air locks--were added to the third containment configuration. The fabrication, structural test data, and the analyses of the containment models are presented in this report.
