WebFeb 1, 2024 · Power peaking factors (PPF) is an important parameter for safe and efficient reactor operation. There are several methods to calculate the PPF at TRIGA research reactors such as MCNP and TRIGLAV codes. However, these methods are time-consuming and required high specifications of a computer system. WebInstantaneous maximum peaking factors for low-lift, pump-dominated systems ranged from 1.3 to 4.7, and the minimum instantaneous flow factors varied from 0 to 0.8. Low-lift pumping stations designed to provide the re- quired head and capacity without consideration of peaking effects can be the most dominant factor influencing peak-flow magnitudes. billy nelson raelyn nelson
