Design of component cooling water system for Comprehensive Research Facilities in Support of CFETR

Abstract

Comprehensive Research Facilities in Support of CFETR is aimed to demonstrate a comprehensive research platform with the highest parameters and the most complete functions in the field of magnetic confinement. The cooling water system is an integral part of a comprehensive research platform. The cooling water system includes component cooling water system (CCWS), chilled water system (CHWS) and heat removal system (HRS). The component cooling water system is mainly responsible for transferring the heat load generated by each subsystem during the operation, preventing the system from overheating. This paper presents the thermal hydraulic design of CCWS for Comprehensive Research Facilities in Support of CFETR. Through the development of the thermal hydraulic model of the CCWS, the AFT Fathom code is used to calculate the key thermal hydraulic parameters and predict the thermal hydraulic behaviour. Based on the results of thermal hydraulic analysis, the key thermal hydraulic parameters have been plotted to evaluate the capability of CCWS, such as the required pump head, inlet pressure, flow rate, inlet and outlet temperature and pressure drop of the customer. This paper will provide design guidance for the construction of component cooling water system (CCWS) for Comprehensive Research Facilities in Support of CFETR.
