At many nuclear power generating facilities throughout the United States and the world, the problem of intergranular stress corrosion cracking (IGSCC) has become the focus of increased attention due to its augmented examination requirements and potential effects in regard to plant economics and operational safety. As a result of this cracking problem, the process in which in-service inspection was performed received considerable attention over the last three years due to the difficulty of ultrasonic detection and sizing of the IGSCC flaws and the implementation of Regulatory Bulletin 82-03. General Electric established examination techniques to examine components at Carolina Power and Light's Brunswick plant maximizing the technique by employing the master/slave system. The system itself consisted of Krautkramer/Branson USIP-11 connected to a video cassette recorder and a separate, relatively inexpensive, video monitor. This mainframe unit is known as the master unit, and the video monitor as the slave unit. A video camera is then trained on the oscilloscope of the master unit and transmits the same presentation viewed on the oscilloscope to the slave unit. The actual operation of this system is described. The master/slave system represents but one method of new techniques developed to address nondestructive examination problems.
