Description

Helium vessel is one of important equipments in target station of CSNS, which maintains an inert environment (helium at a slight positive pressure) around the moderators, provides credited confinement functions, and provides access ports for the proton beam, 20 neutron beams and the target. Helium vessel components should be designed to last more than 40 full power years. Water cooling has been arranged in sections of helium vessel to remove the heat deposited by a 500 kW beam. This paper describes the thermal analysis and thermal-solid coupling analysis which is performed to optimize structural design. (author)
