Reference:

Tech Spec 3.2.1

1.2 Descrfotion

The MAPLHGR Limit is the product of the Fuel-Type MAPLHGR Limit and the minimum of either the power dependent MAPLHGR Fador, MAPFACp or the flow dependent MAPLHGR Fador, MAPFACp. The Fuel-Type Maximum Average Planar Linear Heat Generation Rate (MAPLHGR) limits are determined from the tables listed below.

MAPFACp is determined from Figure 1.2-1 and MAPFACp is determined from Figure 1.2-2.

Below 30% power, two MAPFACp curves are given, one for core flow Greater than 50% and one for core flow equal to or less than 50%.
