Modeling of CHASHMA NPP Reactor Core Using FUMACS Computer Code Package

Depletion modeling of the nuclear power plant (NPP) CHASHMA has been performed for the first and the second cycle. The NPP CHASHMA is 300 MWe PWR operating in Pakistan. The reactor core of the NPP CHASHMA has been modeled by FUMACS computer code package. The FUMACS code package has been developed for in-core fuel management calculations of NPP Krško. It has been validated on the reactor core of NPP Krško. Some modifications of the code package models were necessary in order to simulate depletion of the NPP CHASHMA reactor core. The depletion of the NPP CHASHMA core has been successfully modeled using the FUMACS computer code package. The obtained results for core parameters have been compared with design core parameters. The comparison demonstrated that the FUMACS computer code system has good calculational accuracy level for performing the scoping calculations and for loading pattern development of the NPP Chasma reactor core.
