What percentage of flow is associated with the SG low-low level?

The correct percentage of flow associated with the steam generator (SG) low-low level is 17%. In the context of steam generator operations, the low-low level indicates a critical condition where the water level is significantly below the normal operating range. This specific flow percentage is crucial for preventing damage to the generator and ensuring safe operation; at this level, the steam generation can start to compromise the integrity of the system.

Monitoring the flow percentage related to water levels is vital for operators, as it directly impacts safety protocols and operational adjustments. Understanding this threshold helps in maintaining optimal performance and avoiding the risks of dry-out conditions, which can lead to the overheating of the steam generator components. The other percentage options do not reflect the established industry standards, making 17% the correct choice in this context.
