Human factors study conducted in conjunction with a Mini-Round Robin assessment of ultrasonic technician performance

Technical Report ·
OSTI ID:5423319
This report describes the findings from a limited human factors (HF) study conducted in conjunction with a Mini-Round Robin (MRR) held at the Pacific Northwest Laboratory. The purpose of the HF evaluation was to acquire preliminary data on performance shaping factors that affect ultrasonic testing (UT) reliability; to test the efficacy of relative operating characteristic analysis for representing UT accuracy; and to determine the direction of future HF efforts in the NDT area. The purpose of the MRR was to evaluate the ability of nondestructive testing (NDT) technicians to detect intergranular stress corrosion cracking (IGSCC) using UT techniques. A further purpose was to measure improvements in technician performance following implementation of I and E Bulletin 83-02 and qualification for IGSCC detection at the EPRI-NDE Center. Twelve UT technicians carried out UT for IGSCC on samples of welded sections of piping that either had IGSCC or did not have IGSCC. Each technician also filled out a questionnaire about performance shaping factors that could provide information on relevant UT inservice inspection experience. In addition, the UT equipment used by the MRR teams was evaluated for conformance to HF design principles. 11 refs., 18 figs.
