Nuclear Grade Hydrogen Sensors

GLS’s Nuclear Grade Hydrogen Sensor detects hydrogen in the local area of the sensor and provides the location and concentration of hydrogen so that nuclear plant operators are alerted to the presence and location of hydrogen and directed mitigation activities can be taken to prevent hydrogen explosions.

GLS developed the sturdy Hydrogen sensor so that it can operate and measure hydrogen concentrations in even the worst conditions during a Severe Accident at a nuclear power plant and recent testing has confirmed the capability of the sensors to measure hydrogen before, during and after Severe Accidents at nuclear power plants.

GLS’s Nuclear Grade Hydrogen sensors are qualified to IEEE nuclear safety standards and Severe Accident service. Each hydrogen sensor converts hydrogen concentration from the local area of the sensor directly to an electrical signal. The hydrogen sensor is capable of operating in very high Severe Accident temperatures and radiation environments through the use of patented ceramic active materials and isolation sealing. GLS’s Nuclear Grade Hydrogen sensors have been tested significantly beyond the temperature levels in Design Basis Accidents.

GLS’s Nuclear Grade Hydrogen sensors add a whole new level of protection for nuclear plants by being able to locate and measure Hydrogen concentration inside containment including reactor top head flange and suppression pool hatches and outside containment for monitoring leakage from piping penetrations, electrical penetrations, machine hatches, air locks and spent fuel pool.
