METHOD OF CONSTRUCTING PSEUDO HOT PIN POWER DISTRIBUTION USING IN-CORE DETECTOR SIGNAL-BASED PLANAR RADIAL PEAKING FACTORS IN CORE OPERATING LIMIT SUPERVISORY SYSTEM

摘要

Disclosed herein is a method for constructing a pseudo hot pin power distribution using in-core detector signal-based planar radial peaking factors in a Core Operating Limit Supervisory System (COLSS). The method includes defining a planar radial peaking factor F_xy^K based on in-core detector signals in the COLSS, and expanding the planar radial peaking factor F_xy^K so that the planar radial peaking factor F_xy^K is suitable for a number of nodes of the COLSS. The planar radial peaking factor F_xy^K is calculated only for the in-core detector signals using a preset equation, rather than by using table lookup.
