Will offshore remote-controlled vehicles be used in nuclear applications

J. Johnston

In the nuclear power industry, the offshore remote control vehicle (RCV) concept and much of its developmental design can find direct application. With the addition of specialized sensors and the development of more precise control and reference techniques, the RCV can be …

Flammable Gas Explosion in Large Oil Circuit Breaker

J. Johnston

Although it has long been realized that flammable gases were produced by the decomposition of solid insulation and insulating oil due to faults in electric equipment, this generally has not been considered an explosion hazard in the operation or maintenance of the …
