This document analyzes the thermal profiles of various power extraction limits in a pressurized water reactor (PWR) heated channel. It examines three cases: 1) keeping the coolant exit temperature sub-cooled, 2) keeping the maximum cladding temperature below saturation, and 3) keeping the fuel maximum temperature below the melting point. The second case had the lowest power extraction due to the low cladding surface temperature limiting outlet temperature. While the first and third cases extracted almost the same power, the document concludes the first case should be used as the standard, as it keeps outlet temperature away from saturation while also avoiding high temperature differences that can damage fuel. Numerical computations of the thermal profiles are performed for each case.
