Underwater Remotely Operated Vehicles for Nuclear Reactor Vessels

摘要

This paper describes the development and application of remotely operated vehicles (ROVs) for reactor internals. Stress corrosion cracking (SCC) on reactor internal components have become one of the most important issues in recent years, and demand for the inspection of reactor internals is increasing. Toshiba has developed and applied several types of ROVs that can inspect and maintain welds in a narrow space underwater.
