[en] A 1/8 scale model of a steel containment building will be tested in late summer of this year by the Containment Integrity Division of Sandia National Laboratories, Albuquerque, NM. Included in the model are pipe penetrations, personnel locks, and operable equipment hatches. The 1/8 scale model will be pressurized in steps to well above the design pressure and data taken at each step via a computer controlled data acquisition system. Strain gages, thermocouples, and displacement and pressure transducers have been placed strategically throughout the inside and outside of the model to record data on the model's response to each pressure step. Particular effort has gone into instrumenting the area around and near penetrations although regions away from penetrations are also instrumented for comparison purposes
