Operating experience review of an INL gas monitoring system

This article describes the operations of several types of gas monitors in use at the Idaho National Laboratory (INL) High Temperature Electrolysis (HTE) laboratory. The gases monitored in the lab room are hydrogen, carbon monoxide, carbon dioxide, and oxygen. The operating time, calibration, and both actual and unwanted alarms are described. The calibration session time durations are described. Some simple calculations are given to estimate the reliability of these monitors and the results are compared to operating experiences of other types of monitors.
