The specified SMM Alarm Ratio setting ensures that the assumption that an alarm isgenerated at flux doubling in the Boron Dilution Event analysis remains valid. The countrate is displayed on the SMM.2 Limit not applicable during either a THERMAL POWER ramp in excess of 5% ofRATED THERMAL POWER per minute or a THERMAL POWER step in excess of10% of RATED THERMAL POWER.3 Section 2.14 is based on cycle-specific boron dilution analyses performed byDominion.
