L1C8 Core Operating Umits Report 1.0 Average Planar Linear Heat Generation Rate (APLHGR) (3/4.2.1) 1.1 Tech Soec

Reference:

Tech Spec 3.2.1 1.2 Descriction, The MAPLHGR Limit is the produd of the Fuel-Type MAPt.HGR Limit and the minimum of either the power dependerd MAPLHGR Factor, MAPFACp or the flow dependent MAPLHGR Factor, MAPFACp. The Fue6-Type Maximum Avera0e Planar Unear Heat Generation Rate (MAPLHGR) limits are determined from the tables listed below.

MAPFACp is determined from Figure 1.21 and MAPFACp is detemened 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%.
