“…This program includes a two-fluid pressurizer model, a @ PRISM @ includes neutron kinetics, heat transfer from fuel to coolant, a multiple-loop primary coolant system, a pressurizer, and a steam generator. In Japan, a real-time, accidenttracking PWR simulation program has been developed to investigate small break loss-ofcoolant accidents [73]. Cabral developed a three-dimensional, thermal-hydraulic simulation model for a reactor core [59].…”
