The purpose of this study was to investigate the feasibility of using tracer gas technology to locate leaks in underground RIC-WIL steam pipe casings. A series of controlled model experiments at the contractors plant demonstrated that one or more leaks in a buried steel pipe could be detected by surface measurement of tracer gas concentrations. A full-scale demonstration test was conducted at Naval Air Station-North Island on a 400-foot casing with suspected leaks. Two leaks were localized to within three feet using the hardware and procedure developed during the controlled experiments. Simplification would be required before this tracer gas technique could be used on a routine service basis at Air Force bases. Author
