In the manual development of rod bundle CHF correlation, there are shortcomings and deficiencies such as numerous links, tedious process, large amount of data, high error rate and long computing time, so the integrate CHF correlation development system (ICODES) is researched and implemented by Nuclear Power Institute of China (NPIC). This paper introduces the theory and structure of the ICODES, and performs the validation based on the rod bundle CHF test data and the basic shape of homemade CF-DRW correlation from NPIC. This study indicates that ICODES satisfies the requirements of the development of CHF correlation for fuel assembly design.
