This study simulated a control rod assembly (CRA), which is a part of reactor shutdown systems, inimmersed and fluid flow conditions. The CRA was inserted into the reactor core within a predeterminedtime limit under normal and abnormal operating conditions, and the CRA (which consists of complexgeometric shapes) drop behavior is numerically modeled for simulation. A full-scale prototype CRA droptest is established under room temperature and water-fluid conditions for verification and validation. This paper describes the details of the numerical modeling and analysis results of the several conditions. Results from the developed numerical simulation code are compared with the test results to verify thenumerical model and developed computer code. The developed code is in very good agreement with thetest results and this numerical analysis model and method may replace the experimental and CFDmethod to predict the drop behavior of CRA.
