Summary:
This paper describes some of Battelle's experiences in developing J-R data for nuclear piping materials. Compact specimens were machined from both carbon steel and stainless steel pipe and subjected to testing at elevated temperatures, similar to temperatures encountered in nuclear reactor coolant piping. In many cases, the specimens displayed toughness levels above those considered valid by ASTM standard methods of testing. Furthermore, cracks were grown by about 50% of the original ligament, well in excess of the 10% limit imposed by ASTM Test Method for Determining J-R Curves (E 1152-87)
