This report contains information concerning operation and calibration of detectors utilized at US nuclear power plants for determining concentration of hydrogen and oxygen within the containment structure.A study was prompted by reports that several plants had experienced problems in operating, calibrating, and maintaining the detectors supplied by various vendors. A survey of all nuclear power plants was conducted to identify the specific problems. Discussions were held with key vendors concerning these problems. The major area of interest was centered around problems associated with calibration of the detectors. Many variations from plant-to-plant concerning calibration accuracies, calibration time periods, and frequencies were identified. Another area of prime consideration involved variations as to maintenance of the equipment. Some plants devoted considerable effort to in-house maintenance of equipment while others relied heavily on the vendor for such maintenance. A workshop was conducted with key utility and vendor personnel in attendance to discuss findings of the survey. It was resolved that a much improved coordinated effort between the vendors and utilities would be initiated as a means to resolve existing problems.
