b'Figure 2. Results from design-based loss of coolant accident tests performed with varied-length nuclear-grade FeCrAl.No significant difference could be determined between 4-inch and 12-inch specimens during SATS LOCA tests, so the 4-inch specimens were found to produce valid results.the short-sample setup with Hastelloythickness of3%, so specimens extensions is shown in Figure 1. were epoxy-mounted to measure Thermocouples were attached tospecimen wall thickness post-test for the front and back of the specimenshoop stress calculations.The burst 2 above and below centerline foropening length, width, height, and 12, 8, and 6-inch specimen lengths,tube Outer Diameter (OD) at the 1.5 above and below centerlineburst location were measured with a for 5-inch specimen length, andmicrometer to characterize the burst 1 above and below centerlinefor all specimens.
