Maximum reactivity insertion rate
In order to avoid damage to either the fuel or the core components, the designer has to be cognizant of the maximum reactivity insertion rate, due to control rod withdrawal (during normal or accident conditions), or by dilution of the boron in the coolant (if present). Limits on the maximum linear heat rate and margins to departure from nucleate boiling have to be demonstrated. By analyzing the reactivity worth and the potential allowed speed of movement of the control rods, the designer can limit the reactivity insertion rate.
