Hydraulic analysis on ITER component cooling water system 2B

The ITER Component Cooling Water System 2B (CCWS-2B) is a closed loop which supplies cooling water to the clients of aluminum material. These clients include Coil Power Supply and Distribution System and Neutral Beam Injector (NBI) System. Due to the different modes of operation and hundreds of clients require different inlet pressure, a complicated hydraulic model is developed by means of AFT Fathom 9.0 in this study to perform the hydraulic analysis on CCWS-2B. Flow distribution in different building is investigated, and the pressure profile is presented in this study. Three solutions are introduced to improve the lack of fluid at some worst case point by using the current selected pump. The results obtained in this study can provide support and reference to the final design of CCWS-2B.
