METHOD OF SIMULATING FLOW OF REACTOR COOLANT IN A CORE AND CORE SIMPLIFIED MODEL FOR THE METHOD

摘要

Provided are a method for simulating the flow of a reactor coolant in a core and a core simplified model used therein. The method includes forming a simplified model by arranging a plurality of induction plates to be apart from one another in a vertical direction, each of the induction plates including a plurality of penetration holes for inducing a pressure drop when the reactor coolant flows in the core; performing a reactor coolant flow experiment by using the simplified model to measure a pressure drop when the reactor coolant flows in the core; and checking whether the measured pressure drop of the reactor coolant is within an error range by comparing the measured pressure drop to a reference value.
