MacDonald, D E

An evaluation and demonstration program has been conducted at the EPRI NDE Center to determine the effectiveness of a radiographic technique using the Miniature Linear Accelerator (MINAC) for the detection of intergranular stress corrosion cracking (IGSCC) in boiling water reactor (BWR) piping systems. Theoretical and experimental evidence, based on both field removed and laboratory grown IGSCC, is presented to establish the range of applicability of the MINAC technique. This evidence provides the technical basis for the MINAC for IGSCC detection. The technique has been shown to be highly effective for deep cracks. The detection threshold for the MINAC is not as low as for ultrasonic testing. However, where metallurgical or geometrical conditions prevent effective application of UT, the MINAC technique is the most suitable alternative.
