The Transportation System Development Department at Sandia National Laboratories (SNL) evaluates the structural response of casks being developed to transport radioactive materials. A major part of this activity includes gathering instrumentation data from dynamic impact tests of cask models. These test are performed per the requirements defined in the Code of Federal Regulations 10 CFR 71.73, which includes a 9-m (30-ft) impact onto a flat, unyielding target and a 1-m (40-in.) puncture test onto a 15-cm (6-in.) in diameter puncture probe. The acquisition of reliable, high quality data is an important component of cask certification. One method to estimate the reliability of instrumentation during impact testing is to include evaluation channels for the various transducers (e.g., accelerometers, strain gages) used for measuring the cask structural response. Some accelerometer manufacturers have produced evaluation channels for use in the structural testing of casks. These commercial devices produce very low output, or no output, to applied shock acceleration. There are no commercially available packaged strain gage evaluation channels, however. Consequently, SNL has developed strain gage evaluation channels to estimate unwanted non-strain induced resistance changes that could affect resistance strain measurement data. 3 refs., 1 fig.
