Coolant condition monitor for nuclear power reactor

Patent ·
OSTI ID:5349203

The faster acting junction of a difference junction thermocouple associated with a gamma sensor is located vertically above the other junction to ordinarily monitor local power generation in the fuel core of a nuclear reactor and in response to a reversal in the signal voltage polarity indicate a drop in level of coolant to thereby also function as a coolant monitor. An internal electrical heater enhances the coolant monitoring capability of the sensor, which may also be extended into the dome of the reactor vessel for monitoring conditions therein.
