title = "Evaluation of VERA-CS transient capability for analyzing the AP1000{\textregistered}reactor control rod ejection accident",
abstract = "Control rod ejection events were simulated for the AP1000 reactor core at the end of cycle hot zero and hot full power conditions using the VERA-CS code system. The core was first depleted to end of Cycle 1 and then calculations were restarted to simulate the rod ejection events in full core geometry. These simulations were performed using MPACT standalone with its simplified thermal-hydraulics capability and also MPACT coupled to CTF within VERA-CS. Results from both sets of calculations were compared to identify the differences between MPACT standalone and VERA-CS. It was found that the VERA-CS code system was capable of simulating full core geometry rod ejection events in a stable manner with the expected power pulse resulting from a superprompt critical reactivity insertion and the resulting negative Doppler reactivity feedback. With high-fidelity simulation capabilities, VERA-CS is positioned to support the industry on reactivity initiated accidents, and to assist in recovering lost margin as well as to address data gaps.",
