Human Factors Study Conducted in Conjunction with a Mini-Round Robin Asssessment of Ultrasonic Technician Performance.

摘要

The 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&E Bulletin 83-02 and qualification for IGSCC detection at the EPRI-NDE Center.
