- Cyclone dust
The cyclone filters and desiccant vessels within the CO2 filter rooms were used to remove particulates and water vapour from the coolant CO2 gas. During normal operations, a small proportion of the coolant gas was continuously passed through the multicyclones and then the drying plants.
Particulate material was collected within the dust canister of each cyclone, shielded by a dust bowl. The very fine particulate comprises of graphite dust and reactor vessel/component corrosion products, generated as a result of graphite core erosion and gradual corrosion/degradation of other mainly steel materials.
