Title：An Overview of PWR Reactor Cores Design focusing on MHI Experience
MITSUBISHI HEAVY INDUSTRIES, LTD. (MHI) has considerable core design experience of 24 PWR plants in Japan since the first commercial operation of Mihama Unit 1 of Kansai Electric Power Co., Inc. in 1970. After a half century of continuous improvement on fuel and reactor core design, MHI has contributed to the enhancement of high reliability and efficiency of PWR core performance. With dedicated work, application of high discharged assembly burnup fuel and utilization of Mixed Oxide (MOX) fuel were successfully implemented in Japanese PWRs. This presentation shows the overview and achievements of MHI PWR core design technology. In addition, it also shows the outline of the reactor core design code system GalaxyCosmo-S developed in MHI and its application results to PWR core design and safety analysis including severe accident analysis (ATWS).
